Manitowoc Crane Group Germany GmbH recommends pneumatic grease
spray guns for more effective lubrication of the telescopic slide faces:
Prerequisites – The truck crane must be level.
– The hook block must be unreeved.
– The main boom must be completely retracted and lowered into horizontal
position.
–
A rigging mode must have been set up using the telescope positions
required for maintenance as specified in the rigging tables;
à Lifting
capacity table
.
– The RCL code for the current rigging mode must be entered.
H
If at the start you set up a rigging mode under which the telescope positions
47/100/0/0/0 are released in the context of the corresponding rigging table,
this rigging mode allows you to perform the complete maintenance work on
the main boom.
