Limit Switches
Check that the following limit switches function properly by
attempting to exceed the preset limits.
1. Lowered Position Limit Switch - Outriggers cannot be
deployed beyond the height of 9.8 ft (3 m).
2. Limit Switches for Drive Mode:
a. High Drive Speed Limit Switch - High drive speed is
possible up to a platform height of 11.5 ft (3.5 m).
Once the platform exceeds this limit, only low drive
speed is possible.
b. Maximum Drive Height/Maximum Height without
Outriggers Limit Switch - The maximum allowable
drive height is 50 ft (15.2 m). The liftling function,
without outriggers deployed, is only permitted up to
a platform height of 50 ft (15.2 m) as well.
3. Tilt Switch - If the machine is exceeding a tilt angle of 3°,
the platform cannot be elevated beyond 11.5 ft (3.5 m),
or if driving while elevated, the drive function will be cut
out.
4. Maximum Height Switch - The Maximum Height Switch
cuts out the lift function once the platform reaches 66.6
ft (20.3 m). This maximum height is only achieved when
the outriggers are selected and deployed.
5. Outrigger Interlocks - These switches allow the machine
to be driven when all outriggers are completely
retracted. The switch also prevents the platform from
being raised until the machine is level.
