VPC Trolley Limit Switch Checks
Perform the VPC trolley limit switch checks each time the
crane is assembled at a new job site.
1. Verify that all three limit switch levers Figure 4-46
are
installed parallel to the VPC trolley limit switch housings.
The levers must be positioned straight up-and-down
on the shafts.
To access the limit switches, remove the access cover
over the hole in the bottom left end of the VPC trolley.
Reinstall the cover when done.
2. With the setup mode on (live mast configuration
selected in the RCL/RCI display), proceed as follows:
a. Access the limit switch status information screen in
the main display (Figure 4-47
).
b. Using the switch on the remote control, position the
VPC trolley (1, Figure 4-46
) at dimension B.
c. In the main display (Figure 4-47
), the maximum
position (B) limit switch icon (3) must indicate that
the limit switch is TRIPPED.
If the icon indicates that the limit switch is NOT
TRIPPED, troubleshoot the electric control system
and fix the problem.
The limit switch (3) must be TRIPPED when the
VPC trolley is at the maximum position.
d. Using the switch on the remote control, position the
VPC trolley (1, Figure 4-46
) at dimension A.
e. In the main display (Figure 4-47
), the minimum
position (A) limit switch icon (2) must indicate that
the limit switch is TRIPPED.
If the icon indicates that the limit switch is NOT
TRIPPED, troubleshoot the electric control system
and fix the problem.
The limit switch (2) must be TRIPPED when the
VPC trolley is at the minimum position.
3. Return to step 20c
on page 4-63.
