1 SCOPE

This document is intended to be read in conjunction with Anglo Fatal Risk Standard 2:

Surface Mobile Equipment and its associated technical guideline.

This document provides information concerning towing and recovery procedures. It isrecommended that the example be modified to suit the mine site needs.

2 TOWING OF TRAILERS

a) Weight ratios and suitability of towing vehicles and trailers

The towing vehicle must be of sufficient size to control the tow. Vehicles shall onlytow trailers where the drawbar colour matches the allowable colour shown on thesticker attached to the vehicle. The sticker also stipulates the maximum speedallowable on a formed road.

b) General requirements to tow purpose built trailers:

The towing hitch must be of sound construction and be inspected prior toattaching.

The trailer drawbar must be connected at the correct purpose built towbar orhitch device.

Two-way radio advice shall be given to other road users where the towingprocess constitutes a greater risk to those users.

Consideration should be given to the use of an escort vehicle.

A flashing light is to be attached to the rear of the towed trailer, if it is not fittedwith connected and operating trailer lights.

Safety chains shall be fitted and used as detailed below.

Where high tensile towing chains are used, a break away safety link is to beincluded in the towing chains.

c) Hitch Classification

All trailer and tow vehicle hitches should be common, and should be 70 mm ringdrawbar with matching suitable towbar configuration (Approved Towbar). Onlyvehicles permitted to be used for towing are to be fitted with an Approved Towbar,and these vehicles must carry a sticker in the cabin indicating what (colour) categorytrailers may be towed.

Towbar may be pintle hook, pin and clevis, ringfeeder or other suitable device.

d) Trailer Drawbar Colour Coding

Any trailers permanently based on the mine sites shall have its drawbar colourcoded to allow identification of vehicles permitted to tow it.

8/12/2019 AA_AFRBP_000021

4/12





The Aggregate Trailer Mass (ATM) which is the total mass of the trailer includingany load transferred to the towing vehicle through the drawbar, shall be determinedby the supplier or manufacturer; or by weighing with a crane load cell or other

suitably accurate method.

The trailer colour code and category is determined from the following table:

Drawbar Colour Trailer ATM tonnes

1. White ATM 1.5 t

2. Brown 1.5 < ATM 3.0 t

3. Green 3.0 < ATM 5.5 t

4. Blue 5.5 < ATM 11.0 t

5. Yellow 11.0 t < ATM

The drawbar or A frame shall be painted the associated colour and the ATM shouldbe recorded and marked on the drawbar with legibility checked any time the drawbaris repainted.

e) Towing Vehicle Classification

Light vehicles

Vehicles with manufacturers recommended towing capacity of 2.5tonnes or greater.Vehicles with a capacity of less than 2.5 tonnes shall not be fitted with an approvedtow bar.

Category 1. White 2. Brown 3. Green 4. Blue 5. Yellow

Speed (kph) 60 40 XX XX XX

Brakes not required required

Light medium vehicles

Vehicles with a GVM (Gross Vehicle Mass) of less than 6.0tonnes can tow trailersup to 3.0 tonnes without brakes and 5.5tonnes with Active Brakes. Note that if usualgross operating weight is expected to be less than 3tonnes (the truck has no fixedequipment and is usually unladen) the vehicle should be down graded a category.


Speed (kph) 80 60 40 X X

Brakes not required not required required

Medium vehicles

Vehicles with a GVM in the range 6.0 to 15.0tonnes may tow trailers up to 5.5tonnes

ATM without brakes and 11.0tonnes with Active Brakes operational. Note that ifusual gross operating weight is expected to be less than 5tonnes the vehicle shouldbe down graded a category.

Category 1. White 2. Brown 3. Green 4. Blue

Speed (kph) 80 60 60 40

Brakes not required not required not required required

Heavy Medium vehic les

Vehicles with a GVM of 15.0tonnes or greater can tow trailers up to11.0tonnes ATM

and trailers heavier than 11.0tonnes with additional caution at reduced speed. Notethat if usual gross operating weight is expected to be less than 11tonnes the vehicleshould be down graded a category.


Speed (kph) 80 80 60 60 40

Brakes not required not required not required recommended required

Heavy vehic les

Heavy equipment (Dozers, Graders, Loaders, etc.) can tow any trailer fitted with aconventional drawbar. *Usually the equipment itself will have a speed limit lower

than consideration of the trailer and few items of this equipment are capable of even60kph.


Speed (kph) 80* 80* 60* 60* 60*

Brakes not required not required not required recommended recommended

Brakes on Trailers

Towing vehicles are generally permitted to tow a heavier class of trailer (up to thetowing vehicle weight) if the trailer has brakes fitted and operational. Trailers in thesize range 1.5 to 3.0tonnes (Brown Category) may be towed by suitable light

vehicles providing the trailers are fitted with brakes. Over-ride brakes are permittedfor this category but should be on all wheels excluding wheels on turntables fortrailers over 2.0tonnes.

If brakes are inoperable, the trailer may be manoeuvred by an appropriate lightvehicle on the bench or in the excavation at no more than walking speed, but shallnot be towed on a formed road.

8/12/2019 AA_AFRBP_000021

6/12





Heavier trailers (Green, Blue, and Yellow Categories) should be fitted with brakes(Active Brakes) which are:

operated from the towing vehicle drivers position

acting on all wheels excluding wheels on turntables; and

automatically applying if the trailer becomes detached and for parking.

The brakes on trailers, when fitted as required by this policy, are to be testedwhenever the operating equipment on the trailer is serviced or maintained, and inany event at intervals not exceeding six month.

Safety Chains

All trailers should be provided with twin safety chains, and towing vehicles with twinattachment points. These must be used if the vehicle is to be moved at abovewalking speed or on a formed road. If one chain is missing, the trailer may be towed

with caution at reduced speed, and the defect reported on the shift it occurs, by anyoperator who tows it.

Parking

Trailers shall be safely immobilised prior to disconnection from the towing vehicle.This may be by side stands (stabilising jacks), parking brakes, chocks, or suitableparking rill. Trailers with no provision for parking brakes or jacks should carry chocksfor this purpose.

Contractors and hired equipment

Any trailer coming on site for a short period of time must be marked with itsAggregate Trailer Mass on the drawbar in clearly legible marking, and the trailer

must only be towed by an appropriate vehicle in compliance with this policy as if itwere colour coded according to its weight and brakes.

Special Vehicles

There are a number of special vehicles (cable tractors etc) designed to tow muchmore than their own weight. These need to be considered specially; the limitsincluded in the operator training for these vehicles, and appropriate controls orsignage specially placed.

3 TOWING OF EQUIPMENT

Following safety requirements must be followed for towing equipment not designed as a

trailer: The safest route to destination is to be determined and taken.

The towing vehicle must be of sufficient size to control the tow.

The towing link must be of sound construction and be inspected prior to attaching.

The towing link must be attached to tow points on both vehicles; if this is notpossible, then a secure tow point is to be determined and used.

8/12/2019 AA_AFRBP_000021

7/12





Both vehicles shall be controlled by competent persons after determining the towingmethod to be used.

Two-way radio advice shall be given to other road users.

Consideration should be given to the use of an escort vehicle.

Both vehicles are to have their hazard lights activated while travelling under tow.

The towing speed shall not exceed 40kph unless a light vehicle is towing anotherlight vehicle where the maximum speed shall be 60kph.

4 SAFETY OF PERSONS WHEN RECOVERING EQUIPMENT

Ensure area has been isolated or restricted if necessary before commencingrecovery operations.

A person shall be nominated to supervise the recovery operations (recovery

Supervisor).

Hazard identification and risk assessment shall be conducted prior to recoveryoperations.

Such common things to look out for before entering the area are, but not limited to:

live power

fuel leaks

is the equipment or plant secure (from further movement)?

further movement of ground

water or mud

other equipment working in the vicinity

potential of falling objects

It may be necessary to prevent further movement of the equipment requiringretrieval.

The area may need to be secured to make safe for subsequent operations.

Inspect with caution the equipment to be recovered to assess what equipment andattachments are adequate for a safe recovery.

Prepare recovery area, if necessary, for recovery equipment to work safely in area.

Check integrity of lifting / towing attachments.

Recovery Supervisor shall, prior to the recovery, discuss with all people involved inthe recovery action plan for recovery.

Prior to recovery of equipment, the recovery Supervisor shall nominate person todirect operation of equipment during recovery.

Ensure a means of communication shall be developed e.g. radio, visual, handsignals.

Ensure all unnecessary people shall be removed from area prior to final retrieval /recovery operation.

Ensure the equipment is retrieved to a safe location.

8/12/2019 AA_AFRBP_000021

8/12





Ensure caution is taken whilst removing attachments. Recovery Supervisor shallcommunicate to all personnel involved prior to removing towing or liftingattachments, highlighting hazards and work instructions to reduce risk of personal

injury e.g. harnesses if working at height, gloves, use of mechanical lifting aids suchas cranes.

If towing required after retrieval, see towing procedure.

5 STROPS: RECOVERY OF EQUIPMENT AND VEHICLES

This procedure provides guidelines to ensure the safety of all personnel, when recoveringstuck equipment or vehicles.

1. Ensure the area has been isolated, or access restricted if necessary, beforebeginning the recovery operation.

2. A Designated Competent Person (DCP) must supervise the recovery operations.

3. SLAM the task before beginning the recovery.

4. Some things to look out for before entering the area, may include, but not be limitedto:

a) live power

b) fuelleaks

c) Istheequipment/vehiclesecurefromfurthermovement?

d) furthermovementofground

e) water,mud,slip,triporfallhazards

f) otherequipmentworkinginthevicinity

g) potential of falling objects

5. Before starting the process, make certain that there cannot be an uncontrolledmovement of the equipment or vehicle. This would include provisions for stopping it,once it has been freed.

6. The area may need to be secured to make it safe for your recovery efforts.

7. Determine the strop size required for a safe recovery. There should be a redRecovery Requires nameplate on the dash, or near the ignition key/switch startingcontrol. If the nameplate does not exist the DCP shall determine the correct class ofthe equipment and then later ensure that the correct identifying nameplate isattached to that equipment. This nameplate will identify the minimum class of strop

required. You may use a larger class of strop if desired but if shackles are used theymust comply with the table below.

8. Strop inspection and care: If in doubt, obtain another strop. Tag questionablestrops Out of Service then contact your supervisor as to suitability for use.

Black Snake- rubber coated with yellow stripe. The following items should beexamined before using:

8/12/2019 AA_AFRBP_000021

9/12





a) Eyes at each end are not distorted or damaged, beyond normal wearand tear

b) Cuts in the rubber cover do not violate the Kevlar core beyond a very

minimal degree

c) No abnormal distortion or signs of physical distress are observable

d) Power washing is acceptable; allow to dry before use

e) Store in an enclosed container when not in use

f) Only use in straight-line loading. Never double back or use as a choker.

g) Do not connect two or more strops together in line

h) When in doubt, tag it out!

Plasma 12 Strand, purple with black protective sleeve over its length, grayurethane coated sleeve covering eyes. The following items should be

examined before usinga) Eyes at each end are sound, and do not have cuts through the

protective sleeve, that violate the purple inner core, more than a veryminimal degree

b) Along its length, cuts in the black fabric protective sleeve do not carryinto an individual purple strand more than 1/3rd of the way. Cuts only inthe sleeve are OK, as it does not provide any strength to the strop

c) Abnormal soaking with grease/solvents, or wear and tear beyondnormal use, shall be cause for removal from service and destruction

d) Gentle, low pressure washing is acceptable; allow to thoroughly drybefore use

e) Use edge protectors when necessary to prevent damage to the strop

f) Store in an enclosed container when not in use- do not leave exposedoutdoors

g) Only use in straight-line loading. Never double back or use as a choker.

h) Do not connect two or more strops together in line

i) When in doubt, tag it out!

9. Evaluate the adequacy of the attachment points, and the size of any connectors(such as shackles) to be used. Shackles are only to be used if they are required tohook the strop up to the pulling equipment, or the equipment to be pulled. Manyapplications will not require a connector at all. Refer to the following table for the

minimum strengths required for each class of strop.

3R-Underground 220,000 35ton(fails@420K)

3R-40 314,000 55ton(fails@660K)

10. The lower left-hand corner of the stainless tag on each strop must have stamped theminimum strength shackle required for that class of strop.

11. If you need to use a shackle, make certain that the rating is stamped on the corner.If it is not stamped, tag Out of Service until it is properly marked. The tags on class

LV and 1TR strops shall be stamped 4and 8respectively.

12. Prepare the area, if necessary, to allow the recovery equipment to work safely.

13. Prior to attempting recovery, evaluate if material/payload needs to be removed frominside of the stuck equipment, or from beneath it, to lessen the force requiredwithdrawing it.

14. Check integrity of lifting/towing attachments.

15. The Designated Competent Person shall discuss with all people involved prior tobeginning the process, the exact action plan for recovery.

16. Prior to recovery of equipment, the DCP shall nominate a person to direct operation

of the equipment used during recovery.

17. Ensure a means of communication is used, such as radio, visual, or hand signals.

18. Ensure all unnecessary people are removed from area prior to finalretrieval/recovery operation.

19. Any persons that are required to remain, must always stay out of the line of fireshould a recovery strop or shackle fail.

20. Ensure the equipment is taken to a safe location when recovery has ceased.

21. Ensure caution is taken while removing attachments. The DCP shall communicateto all personnel involved prior to removing towing or lifting attachments, highlighting

the task hazards and detail work instructions to reduce the risk of personal injury.Some examples would include: harnesses if working at height, gloves, use ofmechanical lifting aids such as cranes, etc.

22. If towing is required after recovery, refer to the NMC towing procedure.

23. Only Class LV or 1TR vehicles may be towed using the corresponding strops.
