5.2 HOISTING MACHINE
5.2.1 HOISTING MACHINE WITH BOOM LOWERED
• For the dimensions and mass of this machine, refer to “Specifications 1. Principal
Specifications List”.
• A person who uses the crane to perform hoisting operation must have the crane operation
qualifications.
• Do not perform hoisting operation with a worker placed on the machine.
• Only use a sling (e.g. wire rope and shackles) which is approved and capable of lifting the
mass of the machine.
• Put the machine into a level state when lifting.
• When performing lifting work, place the lock lever at the lock position to prevent the machine
from moving unexpectedly.
• Never get under or around the lifted machine.
• Do not lift the machine in a posture other than that shown in the procedure below, or by using
a sling.
Otherwise, there is a danger that the machine will be out of balance (equilibrium).
CAUTION
• When lifting the machine, use four wire ropes for slinging of the same standard and four
shackles. When lifting the machine, be careful not to allow the wire ropes for slinging to
contact the main body of the machine.
• Wire rope: breaking load 96.7 KN or more (6

37 – ϕ 14

2.5 m)
• Shackle: working load 2.0 t or more Nominal 18 (except format SD)
• When lifting the machine with the boom lowered, be sure to store the hook block in the
normal stowage position. For details, refer to “Operation 3.17.2 Crane Stowage Operation at
the Time of Normal Stowage of Hook Block”.
When lifting the machine, perform the following on a firm, level ground.
1. Attach the hook to the hooking wire rope, set the boom
to the position on the right figure, and fix the hook and
boom to the vehicle body.
CAUTION
If hoisting is performed with the hook stored at the tip
of the boom, the boom will be raised due to the weight
of the vehicle preventing hoisting.
When hoisting with the boom in a lowered state, be
sure to fix the hook and boom to the vehicle body with
the hooking wire rope.
