The boom-raising movement should be performed slowly and stably. And during the operation, the
crane operator must observe the data shown on the display, while other workers must observe the
surrounding areas for potential dangers.
(3) Standing beneath the boom frame is prohibited.
(4) Working radius stipulated in the Load Capacity Charts should be adhered to, even if
no load is attached on the load hook! Non-observance of it is likely to cause the
crane turnover.
5.8.5 Lowering and disassembling main boom
5.8.5.1 Lowering main boom
a) Move right control lever (30) to the right to reel derricking winch off, and then the main
boom will be lowered gradually. When the main boom is lowered to 30° position, return
the control lever (30) to neutral position.
b) Push left control lever (20) forwards to reel off hoisting winch 2 to lower stably the load
hook on the ground.
c) Move right control lever (30) to the right until the main boom head comes into contact
with the ground. Return right control lever (30) to neutral position.
(1) In the process of lowering main boom, the hoisting winch 2 must be reeled off to
avoid the hook’s collision with the pulley head.
(2) Standing within danger area of crane during operation is prohibited.
(3) The boom-lowering movement should be performed slowly and stably. And during
the operation, the crane operator must observe the data shown on the display, while
other workers must observe the surrounding areas for potential dangers.
5.8.5.2 Dismantling boom sections and anchoring rods
a) After the anchoring rods are lowered down on the anchoring rod supports on the
relevant boom sections, remove the pin spindles from anchoring rods, and then
secure them on anchoring rod supports with pin spindles for transportation.
b) Separate boom sections using self-assembly system or an auxiliary crane.
c) Lower A-frame down on the slewing table.
(1) Dismantling is carried out in the reverse order to assembly.
Warnings and safety precautions for assembly should be followed during
dismantling operation.
