4.4 Working area definition system (WADS)
The LMI system has programmed functions for monitoring the working area in accordance with the
area of use of the crane:
• easy to program by menus
• functions can be used individually or in combination
• acoustic alarm and display of a symbol when a programmed limit value is reached or exceeded
• clear display of the programmed limit value in an information menu screen.
The “Working area definition” function described below is an aid for moving the crane
within adjustable boom ranges.
Reaching or exceeding a programmed limit value
does not stop the boom movements!
The crane driver alone is responsible for the safe operation of the crane!
Working area limits are indicated by the following symbols:
Limit type:
Radius
(min. and max.)
Height
Boom angle
(min. and max.)
Slew angle
(left and right)
"Virtual" wall
(up to 5 walls)
