13. TRANSPORTATION 13.3 METHOD OF LIFTING MACHINE ¤ WARNING Never raise the machine with any worker on it. Always make sure that the wire rope used for lifting the machine is of ample strength for the weight of the machine. Never try to lift the machine in any posture other than the posture given in the procedure below. There is danger that the machine may lose its balance. Never lift the machine with the upper structure swung to the side. Swing the work equipment so that it is at the sprocket end and set the undercarriage and upper structure parallel before lifting. When lifting, be careful of the center of gravity and be sure to maintain the balance.
NOTICE The lifting procedure given below applies to machines with standard specifications. The method of lifting differs according to the attachments and options actually installed. In such cases, please contact your Komatsu distributor. For details of the weight, see “25. SPECIFICATIONS”. When lifting the machine, carry out the operation on flat ground as follows. 1. Start the engine, then swing the upper structure so that the work equipment is at the rear of the machine. 2. Extend the bucket cylinder and arm cylinder fully, then lower the work equipment to the ground as shown in the diagram on the right using the boom cylinder. 3.
Stop the engine, check that there is nothing around the opera- tor’s compartment, then get off the machine. Close the cab door and front glass securely. 4. Pass the wire rope between the 1st and 2nd track rollers from the front of the machine and the 1st and 2nd track rollers from the rear of the machine. Note: For machines equipped with a full roller guard for the track roller, pass the wire rope from under the track shoe. 5. Set the lifting angle of the wire rope to 30 – 40°, then lift the machine slowly. 6. After the machine comes off the ground, check carefully that the machine is balanced, then lift slowly. 2-92
