Grove Crane GMK 7450 Lattice Extension Operating Instruction Manual 3112671 – PDF DOWNLOAD

• These operating instructions only apply to lattice extensions which were delivered by Deutsche
  GROVE GmbH.
• In addition, for the operation of the truck crane with a lattice extension described in these
  operating instructions, all details in the included Operat- ing instructions for the GMK 7450 for
  which the lattice extension was deliv- ered, are applicable.

Prerequisites for assembly and operation:

The lattice extensions described in these operating instructions may only be operated together with
a GROVE truck crane GMK 7450 whose serial number is identical with the serial number that is marked
on the lattice extensions.

Safety instructions:

The operation of GMK 7450 with one of the lattice extensions 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 supplied operating instructions of
GMK 7450.
