ORANGE Arrow = Direction
of counterweight movement.
GREEN = Target position (where the counterweight needs to be for a given load).
The crane’s control system moves the counterweight in and out in response to
changes in boom angle, luffing jib angle, and load conditions.
The target position will not be green if the bar in either direction has turned yellow.
GREEN = Up to Full Drum Speed
YELLOW = Indicates reduced drum speed. The shorter the bar, the slower the
drum speed. Speed can be so slow that it appears the drums are not turning.
TARGET RANGE = Movement of the green bar toward the turtle in
either direction indicates that the counterweight is ready to move.
The bar remains green only until it reaches the turtle in either direction
and counterweight movement is required. Then it turns yellow.
YELLOW = Indicates the speed
the counterweight is moving to
get back to the target position.
WHITE = If the bar turns completely white while you are trying to
operate a drum in the corresponding direction, it indicates that the
VPC counterweight is locked. Some functions may not be operable.
RABBIT = Fast
TURTLE = Slow
