DIFFERENTIAL GP 1094717 - Caterpillar

Personal injury or death could result when towing a disabled machine incorrectly.Block the machine to prevent movement before releasing the brakes. The machine can roll free if it is not blocked.Follow the recommendations below, to properly perform the towing procedure.Be sure all necessary repairs and adjustments have been made before a machine that has been towed to a service area, is put back into operation.
This machine is equipped with spring applied, hydraulic pressure released brakes. If the engine is inoperable or auxiliary system pressure drops below 8613 kPa (1250 psi), the brakes are applied and the machine cannot be moved.These towing instructions are for moving a disabled machine a short distance, only a few meters (feet) at very low speed, no faster than 2 km/h (1.2 mph), to a convenient location for repair. These instructions are for emergencies only. Always haul the machine if long distance moving is required.Shielding must be provided on the towing machine, to protect the operator if the tow line or bar should break.Do not allow operator on the machine being towed, unless the operator can control the steering and/or braking.Before towing, make sure the tow line or bar is in good condition and has enough strength for the towing situation involved. Use a towing line or bar with a strength of 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.When towing, attach the tow line only to the tow eyes on the frame. The front tow eye is centered below the radiator grill. The rear tow eye is centered above the bearings in the rear bolster oscillation joint.Do not use a chain for pulling. A chain link can break causing possible personal injury. Use a wire rope cable with loop or ring ends. Use an observer in a safe position to stop the pulling procedure if the cable starts to break or unravel. Stop pulling whenever the pulling machine moves without moving the towed machine.Keep the tow line angle to a minimum. Do not exceed a 30° angle from the straight ahead position.Quick machine movement could overload the tow line or bar and cause it to break. Gradual and smooth machine movement will work better.Normally, the towing machine should be as large as the disabled machine. Satisfy yourself that the towing machine has enough brake capacity, weight and power, to control both machines for the grade and distance involved.To provide sufficient control and braking when moving a disabled machine downhill, a larger towing machine or additional machines connected to the rear could be required. This will prevent it from rolling uncontrolled.The different situation requirements cannot be given, as minimal towing machine capacity is required on smooth level surfaces to maximum on inclines or poor surface conditions.Consult your Caterpillar dealer for towing a disabled machine.
