The length of the hydraulic extension depends on the type of crane.
(4) Manual extensions [option]
(5) Hook [option]
2.5. Accessories on the boom system
Manual extensions [option]
The manual extension is slid by hand into the hydraulic
extension.
Hoist [option]
The hoist is a crane accessory that permits load handling without any or only limited boom
movement. An obvious advantage is that the hoist makes it possible to handle loads far below
ground level. Lifting and lowering are achieved by winding/ unwinding the rope. A number of
auxiliary components are needed, such as intermediate pulleys and a hook pulley. As an option, a
snatch block can be installed to multiply the lifting capacity.
The hoist consists of the following components:
(1) Pressure roller
(2) Switch (for rope-end-monitoring)
(3) Rope
(4) Load sensor
(5) Electronic box
(6) Motor
(7) Hydraulic valve
JIB [option]
The JIB is an additional, folding, lifting device that extends the crane boom. Use the JIB to be able
to reach further.
