MLC650 VPC-MAX™ OPERATOR MANUAL OPERATING CONTROLS AND PROCEDURES
AUXILIARY FRAME ASSEMBLY
The auxiliary frame assembly (Figure 3-2) has two operating
positions:
WORKING Position (View A):
This is the recommended operating position.
RAISED Position (View B):
This position can be used if additional clearance is
required for swinging over job site obstacles.
Lower the auxiliary frame assembly after the
obstacle is cleared. Continued operation with the
auxiliary frame assembly raised is not
recommended.
To change the operating position, see Auxiliary Frame
Operating Positions in Section 4 of this manual.

WARNING
Death or Serious Injury Hazard!
A sudden release of load and/or dynamic loading (due to
swinging, hoisting, or lowering and adverse weather
conditions to include wind) may cause structural damage
which could result in death or serious injury due to shock
loading and unintended motion of the crane.
The auxiliary frame assembly is provided to limit
unintended motion of the VPC-MAX beam and
counterweights during a sudden release of load and/or
dynamic loading (due to swinging, hoisting, or lowering
and adverse weather conditions to include wind).
The auxiliary frame assembly in no way substitutes for, or
lessens, the requirement that the crane must be operated
properly and safely, and that it must be inspected,
serviced, and maintained regularly to minimize the
potential for a sudden release of load and/or dynamic
loading (due to swinging, hoisting, or lowering and
adverse weather conditions to include wind).
