3. Procedures

3.1. General Safety Regulations

1. NRC Industries recommend that all carrier operators wear long sleeves, bright-

colored clothing, work gloves and safety boots.

2. Never jump off the carrier and never use the control box or wheel lift to climb onto

your carrier. If your carrier model is too high to climb, use the side ladders

(optional on 10,000TB models).

3. When climbing onto the carrier, make sure to wear adequate boots, that there is

no ice, cooling liquid, oil, water or any other material that can make the surface

slippery.

4. When operating your equipment, make sure that anyone who is not adequately

trained is outside the security perimeter.

5. When placing your carrier back into the transport position, make sure that no one

is between the vehicle and the carrier.

6. Never place yourself behind, in front or under a load that is moving or that is not

properly secured.

7. Never step over a cable or chain, whether it is tense or not.

8. Always follow your sector’s tie down procedures and regulations.

3.3. Control Box

The two control boxes are located on your NRC carrier. The main control is located on

the driver side, while the auxiliary control is on the passenger side.

Figure 3 – Main control box

The main control includes five (5) hydraulic controls as listed below. They are activated

by an upward or downward motion. When facing the controls, you will find them in the

following order, from left to right:

- The winch lever

- The carrier sliding lever

- The carrier tilt lever

- The wheel lift elevation lever

- The wheel lift extension lever

Both the pressure gauge and the pneumatic winch disengagement control are optional.

The auxiliary control only includes hydraulic commands. When in front of the controls,

they are in reverse order. The controls are activated by pushing or pulling on the control

levers.

A label clearly indicates the commands for each of the control movements.


- 11 -

Figure 4 – Control box label

3.4. Chassis Control Panel

A touch control panel is installed inside your vehicle. It is generally located on the

dashboard, depending on the configuration of the vehicle, and features the following:

- Enable flashing lights switch

- Carrier working lights switch

- PTO sensor indicator light

- Auxiliary fog lights switch

Figure 5 – Vehicle touch control panel

3.5. PTO Control

The PTO is what allows the power of your engine to be transferred to your NRC carrier’s

hydraulic pump. The control in your vehicle will allow you to enable it or disable the

PTO. Following the type of vehicle and transmission, it will be one of the following PTO

types: pneumatic or electric.


- 12 -

3.5.1. Pneumatic PTO Control

Vehicles with a manual transmission generally come with a pneumatic PTO control

similar to the one found in Figure 6.

Figure 6 – Pneumatic PTO control

Follow this procedure to engage the PTO:

- Start the vehicle, put the transmission into neutral and activate the parking

brake.

- Press down on the clutch pedal.

- Pull on the red ring lock valve button found on the pneumatic control and push

the lever to the “IN” position. A red light should appear on the switch along with

an orange light on the control panel.

- Release the clutch pedal.

- Set RPM as required: see the label on the vehicle.

To disengage the PTO:

- Press down on the clutch pedal.

- Pull on the red lock valve button found on the pneumatic control and push the

lever to the “OUT” position. The red light on the switch along with the orange

light on the control panel should turn off.

- Release the clutch pedal.


- 13 -

3.5.2. Electric PTO Control

Vehicles with an automatic transmission or vehicles without a pneumatic circuit

generally come with an electric control to activate the PTO. This control may be similar

to the one found in Figure 7 or may be on a button that is already programmed for this

purpose on the vehicle’s dashboard.

Figure 7 – Electric PTO Control

If your vehicle has a manual transmission, follow the same steps for the pneumatic

control. If it has an automatic transmission, follow the steps below to engage the PTO:

- Start the vehicle, put the transmission into neutral and activate the parking

brake.

- Press on the electrical command to engage or disengage the PTO.

3.6. Standard Accessories

The NRC carrier includes the following standard accessories:

3.7. Winch Procedures


- 15 -

3.7.1. General Procedures

When the winch is operating steadily and gradually, it enables you to ensure that you

are rolling and unwinding the cable correctly, limiting the risk of damaging the hauled

vehicle. It also increases the life expectancy of the equipment.

For a smooth operation, the winch is activated by a directional and proportional

hydraulic control. Roll or unwind the cable by moving the control lever in the direction

that is indicated on the control label.

3.7.2. Disengaging the Winch

To allow the cable to unwind quicker, you can disengage the drum from the winch.

There are two devices that disconnect the winches. Your NRC carrier will be equipped

with one of these devices following the type of vehicle and options selected.

To manually disengage the winch, pull directly on the winch handle; shapes and

positions may vary depending on the model. An example of a handle is shown in the

next figure.

- Always remember that your NRC carrier winch is powerful and that it can

cause serious damage.


- 16 -

Figure 10 – Winch with the manual disengagement handle

The pneumatic disengagement is done by the toggle pull switch found at the bottom of

the main control panel. Push to disengage the winch and simply pull to engage it again.

3.7.3. Use of Winch in Movement

Winches are not designed to retain or secure the load during transport; therefore, a

winch should never be over extended during transport. Shocks and after-effects of a

restrained load may damage the winch. Keep a minor tension on the cable when your

vehicle is in movement. Use adequate devices to secure the load onto the carrier.

3.8. Standard Carrier Procedures

- Vigilance is required when operating a carrier because it is difficult to

see all around it.

- Before operating the carrier, walk all the way around it to make sure

the way is clear.


- 17 -

Your NRC carrier’s deck is operated by two levers located on the hydraulic valve. The

lever controlling horizontal movement moves the carrier back and forth, while the lever

controlling vertical movement serves to tilt the carrier into its loading position, and back

down to its horizontal position.

3.8.1. Putting the Carrier into Loading Position

- Using the hydraulic valve lever, slide the carrier back until the yellow arrow

reaches the control panel position. (This operation kicks the carrier deck away

from its front lock.)

Figure 11 – Step 1: Sliding back the carrier

- Tilt the bed at a 20-degree angle and, with the help of the hydraulic valve lever,

continue to slide the carrier deck backward.

Figure 12 – Step 2: Inclination of the carrier

- When the deck has reached the furthest position back, tilt it so that it touches

the ground.

Figure 13 – Step 3: Sliding the carrier backward to the ground


- 18 -

- If there is a load on the carrier, you can use the tow bar to stabilize the truck

during this procedure. (See Section 3.9 for the tow bar procedure.)

3.8.2. Returning the Carrier to Transport Position

- If there is a load on the carrier, you can use the tow bar to help the carrier off

the ground before initiating the procedure. This will stabilize the truck, preventing

the carrier from dragging along the ground and damaging the pavement.

- Slightly lower the carrier’s inclination.

- To place a load on the truck, slide the carrier forward until the arrow is aligned

with the control panel.

- Return the carrier to a complete horizontal position.

- Slide the carrier forward until it rests in its back position over the bolt.

- Before moving the carrier forward or backward, make sure that there

are no chains, hooks or other devices underneath the body. They could

collide with the carrier’s components and cause serious damage.

- If there is a load on the carrier, make sure it is blocked and braced to

prevent movement during inclination.

- Never fully slide the carrier backward prior to tilting it, especially if it is

loaded. The carrier is not designed to support or lift heavy loads at its

extremity.


- 19 -

Figure 14 – Avoid this position when load is at far end of carrier


- 20 -

3.9. Tow Bar Procedures

3.9.1. Standard Procedures

The last two control box levers are for operating the tow bar. In order to move the tow

bar up or down, and to extend or retract the telescopic section (tow bar extension),

move the levers as per the instructions printed on the control panel label.

3.9.2. Stabilization using the Tow Bar and Spades

When loading or unloading vehicles, you can use the tow bar as a stabilizer. This will

prevent your truck from lifting up due to the load and the rear axle.

To help secure your truck when hauling with a winch, use the spades to lower the tow

bar until the wheels begin to lift off the ground, bringing the entire weight to bear on

the spades.

- Never exceed the tow bar’s indicated capacity for your specific NRC car-

carrier and truck. Disregarding this warning may cause loss of control of

the vehicle or even an accident.

- Never use the tow bar to jack up your truck or any other vehicle for the

intention of working underneath it. The tow bar is not designed to be

used as a jack.

- When backing up, keep in mind that the tow bar exceeds the lenght of

your truck.


- 21 -

Figure 15 – Using the spades

3.9.3. Tow Bar Accessories

There are two types of tow bars available for hauling with different accessories that can

be added on. The accessories are illustrated below, and their functions are described in

Section 3.12.

3.9.4. Lifting Accessories

Figure 16 – Hauling plate

Figure 17 – Heavy towing bracket


- 22 -

Figure 18 – Pivoting bracket adaptor

Figure 19 – Wheel-lift system


23

3.10. Truck and Carrier Stability

- Always respect your NRC carrier’s capacity. If you exceed the loading

capacity, you may damage some components and put your safety and

that of others at risk.

- Never exceed your truck’s loading capacity and respect loading limits

stated by provincial/state regulations.


24

3.10.1. Lengthwise Weight Distribution

It is important to consider the lengthwise weight distribution to ensure stable and

adequate control of your truck and to respect loading regulations.

Figure 20 – Load too far back

Figure 21 – Correctly centered load

Generally, you will exceed the loading capacity of your truck's front axle if you place the

load too far forward. Conversely, if you place the load too far back, or pick up a heavy

load with the tow bar, chances are that you will exceed the rear axle’s capacity, and

steering won’t be sufficiently heavy, possibly risking loss of control of the truck.

Therefore, make sure that the load is well placed, ensuring adequate weight

distribution. NRC recommends to keep at least 50% of the initial charge on the front

axle.

. Figure 22 – Load too heavy for the tow bar


25

Refer to the local regulatory documentation to find out how to compute weight

distribution over your vehicle’s axles.

3.10.2. Lateral Weight Distribution

It is necessary to centralize the load on your carrier, as much as possible, to prevent the

truck from tipping over. The vehicle will not tend to rock as much, and the weight of

your NRC carrier’s components will be evenly distributed.

Figure 23 – Correct load distribution

Figure 24 – Incorrect load distribution

3.10.3. Suspension Results

Some vehicles must be braced with devices used to block the wheels. If this is the

case, keep in mind that the part of the carried vehicle hung over the suspension may

sway on the carrier during transport. You will need to adjust your driving accordingly.


26

3.11. Bracing the Load

Your NRC carrier has several chain anchors located all around and along the middle of

the carrier. An NRC carrier anchor has a capacity of 5,000 lbs. (2 270 kg).

Figure 25 – Anchorage locations

Insert the chain’s link into the anchor to fasten the chain as shown in Figure 26. Never

use hooks as shown in Figure 27 to secure a chain to an anchor. If anchoring is not

performed appropriately, you can cause damage and put your security and that of

others at risk.

- Always respect you provincial or state tie-down standards. - Always use chains, straps or other bracing devices approved by

regulatory organisations.


27

Figure 26 – RIGHT way to use anchors

Figure 27 – WRONG way to use anchors

When choosing bracing devices, make sure that they are compatible with your NRC

carrier’s anchorages. Your authorized NRC distributor supplies all of the necessary

products for your carrier and they can provide information about those items.

Regularly inspect your carrier's anchors for deformations and perforations. Never use a

damaged anchor; have it repaired as soon as possible by an authorized NRC Distributor.


28

3.12. Loading and Unloading a Vehicle

The procedure below is a generality and may not apply to all situations that you may

encounter with your NRC carrier. Due to various situations, NRC does not accept any

responsibilities for the procedures suggested below.

3.12.1. Estimating the Distance

- When you need to haul a vehicle, first make sure that the site is secure and that

the way is clear for the hauling procedures.

Before loading or unloading, you must observe all of the following criteria:

- Familiarize yourself with all of your NRC carrier’s controls and

accessories.

- Understand the basic principles of hauling a vehicle.

- Create a safe environment for yourself and for others by working, as

much as possible, in a secure place and by clearly indicating your

presence.

- Keep anyone who is not adequately trained away from your working

zone and shielded from danger.


29

- Position your truck in front of the vehicle to be hauled and engage reverse. Back

up, leaving a distance of 10 to 15 feet between the two vehicles, as illustrated in

Figure 28.

Figure 28 – Preparation distance: 10 to 15 feet

3.12.2. Loading the Vehicle

- Before getting out of your truck, engage the PTO and adjust the engine speed

according to your vehicle’s and your NRC carrier’s required RPM.

- Lower the end of the carrier to the ground. (Refer to Section 3.8 for the carrier

procedures.)

Figure 29 – Positioning the carrier

- Disengage the winch and pull the cable up to the front of the vehicle to be

hauled.

- Secure a chain (or an adequate belt) to the anchors recommended by the

manufacturer of the vehicle being hauled. Never connect the cable’s hook directly

to the hauled vehicle.

- Engage the winch and wind the cable in, but make sure that the cable is not

under tension.

- Place the vehicle in neutral and load it onto the carrier. (Refer to Section 3.7 for

the winch procedures.)


30

- When the vehicle is positioned on the carrier, install two blocking devices on the

front (one on each side). Do not stand behind the hauled vehicle until it has been

securely blocked and braced.

Figure 30 – hauling the vehicle

- Put the vehicle’s parking brake on and engage the parking position.

- Raise the carrier by following steps 1 to 3 in Section 3.8. If necessary, use the

tow bar as a stabilizer.

- To install the rear blocking devices, keep the carrier slightly tilted. This will

prevent the vehicle from moving forward.

Figure 31 – Securing the vehicle with adequate blocking devices

- Install recommended blocking devices for the hauled vehicle.

- Secure the carrier platform in the transport position.

Figure 32 – Bolt-in transport position

- Perform a final inspection. Make sure that the blocking devices are secured and

that none of the vehicle’s (or your carrier’s) components will move during

transportation.


31

Figure 33 – Verify all blocking devices before heading out

- Before leaving, disengage the PTO.

3.12.3. Unloading

- Before getting out of your truck, engage the PTO and adjust the engine speed

according to your vehicle’s and your NRC’s carrier requirements.

- Bring the carrier back and tilt slightly.

- Remove rear blocking devices.

- Lower the carrier's extremity to the ground. (Refer to Section 3.8 for the carrier

procedures.) If necessary, use the tow bar as a stabilizer.

- Place the hauled vehicle into neutral and disengage the parking brake.

- Make sure that nobody is behind the hauled vehicle before removing the blocking

devices.

- Unwind the winch’s cable in order to lower the vehicle to the ground.

- Once the vehicle is completely off the carrier, put it in the parking position and

engage the parking brakes.

- Unfasten the cable, chain or belt.

- Raise the carrier, gather all accessories and secure the cable to prevent

movement during transportation.

- Before leaving, disengage the PTO.

- Consult the vehicle’s manual to locate where the chains need to be

used on the hauled vehicle.

- Always respect your provincial or state blocking/bracing and hauling

regulations.


32

3.12.4. Using the Wheel-lift A load must be on the carrier before using the wheel lift, as indicated in Figure 34.

Figure 34 - Load on carrier

The following section outlines the procedure for using the wheel-lift.1

- Place the truck in line with the vehicle to be hauled. Position the truck at a

distance of three to four feet from the hauled vehicle, as indicated in Figure 35.

Figure 35 – Place your truck about four feet from the hauled vehicle

- Lower the tow bar to the ground and extend it so it leans slightly against the

front wheels of the vehicle to be hauled.

- Install the wheel lift retainers onto the tow bar by placing them on the rear of the

tire and on the outside of the wheels, as indicated in Figure 34.

- 1 See Section 3.9 Tow Bar Procedures for more details.


33

Figure 36 – Installation of wheel-lift retainer

- Install the L-arm and retaining pins, as indicated in Figure 37. The wheel-lift

retainers may have to be adjusted to line up properly with the holes for the pins.

Figure 37 – Installation of L-Arm

- Check that the wheel lift does not cause any obstruction as the tow bar is slowly

raised, lifting the hauled vehicle, as indicated in Figure 38.

Figure 38 – Raise the hauled vehicle and check for obstructions

- Raise the vehicle high enough so that it does not touch the ground during

transport. Verify that the tail end of the hauled vehicle does not drag on the

ground.

- Use the tow bar extension to adjust the distance between the truck and the

hauled vehicle. Check that there is enough room between the hauled vehicle and

the truck for turning, as indicated in Figure 39.


34

Figure 39 – Leave enough room between the truck and the hauled vehicle for turning

- To secure the hauled vehicle, use the retractable safety chains found in the

centre of the truck. Do not forget to cross chains to ease turning.

- Place one chain under the tow bar and secure it into the provided anchor.

- Reverse the procedure when unloading the vehicle from the wheel-lift.

3.12.5. Using Tow Plates

- The following section outlines the procedure for using tow plates.2

- Install the tow plates onto the T-bar and adjust them according to the width of

the hauled vehicle.

- Back up the truck to the recommended distance (refer to Section 3.12.1) and use

the tow bar’s extension to bring the T-bar close to the hauled vehicle.

- Attach chains to the hauled vehicle’s anchors as recommended by the

manufacturer.

- Insert a chain link from each of the chains into the tow plates and secure them

into the hooks situated at the back of the tow plate.

- Install the accessory supports onto the T-bar and adjust the function to the width

of the hauled vehicle.

- Place the bracket accessories in the wheel-lift anchors and adjust the length to

the diameter of the hauled vehicle’s wheel. Install pins to keep the bracket in

place.

- Lower the tow bar close to the ground and extend it to lean slightly against the

front wheels of the hauled vehicle.

- Install slide onto the bus adaptor’s arm accessories and tighten behind the

wheels. Install pins to keep in place.

- Verify that the wheel lift does not interfere with any other parts as you slowly

raise the tow bar to lift the hauled vehicle.

- Put belts around the wheels and attach them to the carrier’s rails.

- Tighten belt with tensioner to secure the wheels correctly.

- Lift the vehicle high enough so that it does not touch the ground during

transport. Verify that the tail end of the hauled vehicle does not drag on the

ground.

3.12.9. Using the Winch for Recovery The carrier's winch can be used for certain recovery operations; however, note that a NRC carrier is not a wrecker and is not intended for such activity. The following procedure is for using the winch for recovery operations.

- Verify the carrier is in a locked-in position.

- Install the roller-guide at the end of the carrier into the anchor provided.

(Recommended for side and straight recovery operations.)

Figure 40 – Roller-guide (optional)

- Install the retaining pin and hair pin.When on a slippery surface, install the

spades onto the tow bar.

- Use the tow bar to stabilize and slightly raise the truck.

Figure 41 – Use the tow bar to stabilize truck

- Disengage the winch and pass the cable through the roller-guide.

4. Maintenance

4.1. General Parts Maintenance 1. Inspect and grease cables.

2. Verify the winch oil level and grease.

3. Change the oil filter after the first six months and afterwards yearly.

4. Grease all of the lubrication points. To find all of the areas to be greased see

Section 4.2.

5. Lubricate the slide strips (see Section 4.3) by using grease to increase life

expectancy and reduce friction.

6. Equipment inspection is recommended after use to make sure everything is in

good condition for continued use.

7. Regular maintenance will keep equipment in good condition, saving or delaying

costly repairs.

4.5. Hydraulic Pressure Adjustment The carrier's hydraulic pressure is factory set. A pressure gauge winch is an

available option. To record an exact reading, adjust the engine speed to be

between 600 and 800 RPM for a large engine (more than 270 hp) and

between 600 and 1,000 RPM for a small engine (less than 270 hp). For

Ainsin or Allison transmissions, contact the manufacturer to adjust the PTO

versus the engine speed.

4.6. Tow Bar’s Lock Valve It is normal for the lock valve to make noise while operating, depending on

speed and the weight of your load.
