Note – Having the telescoping cylinder repaired
The supplied maintenance manual GMK 4100L-1 already specifies that you
must have the locking system on the main boom inspected annually (M12)
by Manitowoc Crane Care or an authorised GROVE dealer.
Especially the head of the telescoping cylinder is checked and adjusted
during this annual maintenance work. Components can be replaced if
necessary. The gap dimensions are corrected with shims if necessary.
Conversion from head type (A) to type (B) is possible after consultation with
Manitowoc Crane Care;
