Lifting procedure
CAUTION
When the machine is raised, check that there is no oil leakage
from the hydraulic circuits.
When carrying out the lifting operation, please contact your
KOMATSU distributor.
Lifting work can be carried out only for machines with lifting
marks. Before starting the lifting operation, stop the machine in
a horizontal place and do as follows.
1. Start the engine, make sure that the machine is horizontal,
then set the work equipment to the travel posture.
For details, see "Preparations for moving the machine
(3-113)".
2. Check that the work equipment control lever is at the HOLD
position, then set the work equipment lock lever to the LOCK
position.
3. Stop the engine, check that the area around the operator’s
compartment is safe, then lock with the safety bar so that the
front frame and rear frame do not articulate.
4. Use wire ropes and slings that match the weight of the
machine, and wind the wire rope and fix it to the lifting points
as shown in the figure.
NOTE
z
Use protectors, etc. so that the wire ropes will not be broken
at sharp edges or narrow places.
z
Use spreaders and bars having sufficient width so that they
will not touch the machine.
z For machines equipped with a rear full fender, remove the
rear full fender before carrying out the operation.
5. After setting the wire ropes, lift up the machine and stop at
100 to 200 mm (3.9 to 7.9 in) above the ground, and check
that the wire ropes are not slack and the machine is level,
then lift up slowly.
