The W.L.L. is adequate for the load.
The colour coding (where applicable) is current and the trolley has a plant number. ID mark.
Examine side plates and check for ware, distortion and cracks.
Examine wheels, axles, bearings, wheel treads and flanges.
If geared travel, check gear teeth on wheel flanges and drives sprocket of hand chain wheel shaft for alignment, broken teeth etc.
Examine hand chain and hand chain wheel to ensure chain seats properly in the chain sprockets.

Where an adjusting bar is fitted, check for straightness and examine threads for stretch/damage and check function of locking device.
Ensure both the female threaded knuckles (mounted on the side plates) are not damaged or deformed.
ERECTION OF BEAM TROLLEYS
10.6 Measure the beam flange on which the trolley is to be fitted and while the trolley is still on the ground/deck, open out to just over the beam flange width, hook on one side of the trolley and close again until desired width is obtained.
10.7 Remember to lock the adjusting bar. Please note, on the PT model’s the adjusting bar is locked by a screw located in the adjusting bar collar.
10.8 Whichever type of trolley is being fitted the recommended clearance between the edge of the beam flange and the wheel flange is 2.5mm (332″) i.e. flange width plus 5mm (316″) total
10.9 Ensure the beam flange is clear of any obstructions and is clean and free from debris.
10.10 Ensure operating chains will not foul or snag during travel.
