GANTRY LIMIT SWITCH
The gantry has a limit switch (3, Figure 4-6) which provides a
digital input to the crane’s programmable control for mast
raising operation.
Operation
When gantry (1) is less than fully raised, limit switch (3) is
open.
When gantry is fully raised, actuator (2) closes limit switch
(3).
Check limit switch for proper operation each time crane is
assembled.
Adjustment
The gantry limit switch was set at the factory and should not
require periodic adjustment. Adjustment is required if parts
are replaced.
1. Park crane on a firm level surface or level crane by
blocking under crawlers.
2. Fully raise gantry (see mast raising procedure in Section
4 of Operator Manual).
3. Loosen screws securing limit switch (3) to frame.

5. Slide limit switch up against actuator (2) until switch
“clicks” closed.
6. Hold limit switch in place and tighten mounting screws.
