Gantry Crane Operator ReminderDID YOU INSPECT YOUR UNIT TODAY

A bridge crane means;a powered crane comprising a bridge beam mounted at each end to a carriage, capable of travelling along elevated runways and having one or more hoisting mechanisms arranged to traverse across the bridge.

The information in this show is for operating a Remote Operated Bridge and Gantry Crane.

A gantry crane means;a powered crane comprising a bridge beam, supported at each end by legs mounted on end carriages capable of travelling on supporting surfaces or deck levels, whether fixed or not and which has a crab with one or more hoisting units arranged to travel across the bridge.

Daily Operator Inspection Requirements

– Daily inspections should be performed at the beginning of each shift or before initial use of the crane each shift by the operator or appointed person.


– Make sure crane or hoist is not tagged out. If a tag is in place, it is usually located at the power disconnect to the runway or on the pushbutton station.

– Check the load block to make sure all sheaves are running freely and sheave covers/guards are in place.


– Inspect the hook for the following:1. Is the safety latch in place? Does it operate correctly?2. Is the hook bent or twisted? The twist cannot exceed 10° from the plane of the

unbent hook or as recommended by the manufacturer.3. Has the throat opening increased? The throat opening cannot increase by

more than 15% or as recommended by manufacturer. 4. Check the bowl conditions. Are there any gauges, nicks or cuts that could

damage synthetic slings and etc.?5. Check the rotation of the hook. Does it rotate freely the whole 360°?


– Inspect the wire rope to make sure it is lubricated and that none of the following conditions exist:

1. No kinks2. No broken or cut strands3. No bird caging4. No corrosion5. No core protrusion6. No crushed sections of rope

6.


– Inspect the control device to make sure all warning labels are in place and there are no cracks or missing bolts in the case.


– Inspect the system conditions1. Visually inspect the runway system. Are all bolts in place? Are there

any obstructions on the runway?2. Visually inspect bridge, trolley and hoist connections. Does everything

appear normal?3. Visually inspect the mainline conductor bar system. Are the

conductors aligned properly? Are all joint covers in place? Are there any broken or loose support brackets?


– Check Operational Functions1. Does the “E” stop function correctly?2. Do all the directional buttons and motions function correctly?3. Test the hoist limit switches and any travel limit switches, if present, to

ensure they are operating correctly. This should be done without load.4. If there are any horns or lights present, do they function properly?5. Do all motions of travel run smoothly with no unusual sounds

present?6. Check the ground for any signs of oil leakage.7. Pick up a load and make sure the brakes are functioning properly.


If any damage or malfunctions are noted during the daily inspection, the operator shall immediately advise the appointed person so corrective action can be taken.

If a malfunction occurs during operation, the operator shall immediately advise the appointed person so corrective action can be taken.

If corrective action has not been completed by the end of the shift, the operator will advise the operator or operators of the next shift that corrective action is required and verify the crane is tagged out with an out of order sign.

Periodic Inspection A periodic inspection is a detailed

visual and operational inspection whereby individual components are examined to determine their condition. The periodic inspection is performed as often as quarterly and is based on service, environmental and application factors as determined by a qualified person or as outlined in the following table.

Operational Safety • Do not overload the crane or hoist. Make sure the

combined weight of the lifter and load does not exceed the rated load capacity of the crane or hoist.

• Refuse to make lift if you are unsure of any issues. Do not proceed until all issues are resolved.

Operational Safety • Take instructions only from the person designated to give

signals.

• Do not ride or allow other people to do so.

Operational Safety

• To pick up a load, move the crane and hoist/hook directly above the load to eliminate the possibility of side loading and minimize load swing.

Operational Safety

• Before lifting, ensure that everyone is clear of any pinch or crush zones.

• When starting to lift the load, only lift it a few inches off the ground to verify hoist brake is functioning properly before continuing with the lift.

Operational Safety

• Make sure the rigging is in good condition and that safe rigging practices are applied.

• Ensure rigging is appropriate for the load size, shape and weight.

Operational Safety

• Always maintain a clear view of the crane path so you can observe any obstacles or personnel in your path.

Operational Safety

• Use one continuous motion when traveling. Try not to start/stop (plug) as this will result in load swing.

Operational Safety – Moving a Load

• Do not lift loads over people. Stay out from under the load and make sure other people remain at a distance.

• Do not become distracted while traveling. If you need to speak with someone, cease operation of the crane.

Operational Safety

• Never leave a suspended load unattended. If you must leave the area, lower the load to the ground before doing so.

Operational Safety – Moving a Load

• Stay clear while moving a load. Do not allow the load to swing. Use a rod to push the load or a tag line to pull the load. Exercise particular caution with sheet lifters. Be sure to keep the load level. Tilting the lifter could cause the load to slide off the lifter.

Operational Safety • When the crane is not in use, always raise the crane

hook above head level.
