The 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 be created with a telescoping status which satisfies
the lifting capacity tables necessary for maintenance;
à Lifting capacity
table
; Section Telescoping sequences for greasing the boom.
– 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
50/100/0/0/0 are released in the context of the corresponding lifting capacity
table, this rigging mode allows you to perform the complete maintenance
work on the main boom.
