Accessories on the boom system
Manual extensions [option]
Manual extension is slid by hand into the
hydraulic extension.
Hoist [option]
The hoist is a crane accessory which 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 is achieved by
winding/ unwinding the rope. A number of
auxiliary components are needed, such as inter-
mediate pulleys and a hook pulley. As an option,
a snatch block can be installed to duplicate lifting
capacity.
The Hoist consists of the following compo-
nents:
•
Wear plate
