PRECAUTIONS FOR OPERATION SAFETY TOWING WHEN TOWING G Injury or death could result if a disabled machine is towed incorrectly or if there is mistake in the selection of the wire rope, so always do as follows. G Do not tow in a different way from the method given in the section "METHOD OF TOWING MACHINE (PAGE 3-130)". G Always wear leather gloves when handling wire rope. G When carrying out the preparation for towing with another worker, agree on signals before starting the operation. G If your machine is towed by another machine, stop the engine and release the brake. Please contact your Komatsu distributor to have the brake released.
G It is dangerous to tow a machine on a slope, so choose a place where there is a gradual slope. If there is no place with a gradual slope, carry out work to make the slope as small as possible. G When connecting up a towing machine,do not let anyone enter the area between the towing machine and the equip- ment being towed. G Do not straddle the towing cable or wire rope. G If your machine is towed by another machine, ALWAYS use a wire rope with a sufficient towing capacity. G Set the towing machine and the towing connection of the equipment being towed in a straight line when connecting it. G Take up the slack in the wire rope and tow the machine.
G When pulling out the machine getting stuck in mud, use the towing hook. G If the machine is stuck in sandy soil, dig out the soil around the towing hook, then use the towing hook to pull the machine out. Permissible load for towing hook: 29,300 kg (288,371 N) G Never use a wire rope which has cut strands (A), reduced diameter (B), or kinks (C).
