About these operating instructions:
Abbreviations used:
These operating instructions describe a load increasing system, which is available as additional
equipment. The system is called Mega Wing Lift and is abbreviated in these operating instructions
to MWL (Mega Wing Lift).

Validity of these operating instructions:

• These operating instructions only apply to original parts supplied by Manitowoc Crane Group Germany
  GmbH and describe the operation of the MWL.
• In addition, operation of the truck crane is also subject to all the specifica- tions in the
  Operating instructions accompanying the GMK 7450 for which the MWL was manufactured.
  For the operation of the truck crane with the lattice extensions described in these operating
  instructions, but without the MWL, the GMK 7450 Lattice extension operating instructions apply.

Prerequisites for assembly and operation:

The MWL described in these operating instructions may only be operated together with a GROVE GMK
7450 truck crane whose serial number is iden- tical with the serial number that is marked on the
MWL.

Safety instructions:

The operation of GMK 7450 with the MWL described in these operating instructions is subject to:
– the basic safety instructions to be found in the subsequent section Basic safety instructions
and
– the safety instructions contained in the operating instructions supplied for the GMK 7450.
