GEROTOR AS 3G8996 - Caterpillar

Use of incorrect methods during preparation or towing of disabled machines.This could result in a serious accident causing injury or death.The following procedures must be followed when preparing and towing the machine.
This machine is equipped with spring applied, air pressure released parking brakes. If the engine cannot be run the air compressor will be inoperable and it may not be possible to release the park brake using the hand control. In this case the wheels must be blocked and the brakes released manually.The transmission mounted parking brake cannot be released manually and it will be necessary to disconnect the transmission from the road wheels by removing the final drive covers and withdrawing the sun gear and axle shaft assemblies.The towing instructions which follow are for moving the machine a short distance at low speed to a convenient location for repair. Do not exceed 2km/h (1.2 m.p.h.). These instructions are for emergencies only. For long distance hauling load the machine onto a suitable breakdown vehicle.Shielding must be provided on the towing machine if the operator can be injured due to the tow line or bar breaking. Similarly, the operator's compartment of the disabled machine must be shielded if a man is to be present during towing.Do not allow any person on the disabled machine unless the operator can control the steering and/or braking. Even then only the operator should be allowed on the machine.Before towing, make sure the tow line or bar is in good condition and is strong enough for the towing situation involved. Use a tow line or bar which is strong enough to pull at least 1.5 times the gross weight of the towing machine, for a disabled machine stuck in mud or when towing on a grade.Gradual and smooth machine movement is necessary during towing. Quick machine movement could overload the tow line or bar and cause it to break.Normally, the towing machine should be at least as big as the disabled machine. Satisfy yourself that the towing machine has enough brake capacity, weight and power to control both machines. Take due account of the grade, distance and conditions involved.To provide sufficient control and braking when moving a disabled machine downhill, a larger towing machine and a solid tow bar will be required. The steering frame lock links must also be in place - see the section "Lifting the Machine." Additional machines connected to the rear may also be required to prevent the disabled machine from rolling away.If the machine is to be towed downhill and needs to be articulated (manouvred) it is necessary to have a towing machine at the front to manouvre the tractor unit and additional machines at the rear to control the trailer unit. Only then can the steering frame lock links be left off.The specific requirements of all towing situations cannot be anticipated. Minimum towing machine capacity is required on smooth level surfaces while maximum towing machine capacity is required on grades with poor ground conditions. If in doubt consult
