DANGER
!
Never go under a platform! To avoid personal injury or death, be
sure the platform has been blocked from underneath! See “Blocking
Instructions.”
LEVEL LIMIT SWITCHES (Fig. 29)
Level limit switch Kits (quantity depends on application – typically one per level),
including field-located cam strikes, have been shipped loose to be field mounted, wired,
and adjusted to sense the status/position of the lift carriage.
1. Locate & weld the limit switch cam striker assembly to the top of the 48” carriage side
guard or hand rail in the orientation & location shown.
2. Find & assemble the adjustable limit switch kits as shown, including the Unistrut
mounting channel (Fig. 31).
3. Once assembled, orientate and field weld the Unistrut channels in such a way as to
allow the limit switch arm to make contact with the limit switch cam when the carriage
is at that corresponding level – leaving room for adjustment.
4. For best results in adjusting position of the switch, loosen the mounting bolts that hold
the switch to the Unistrut channel just enough so that the switch can be lightly
“tapped” into position.
NOTE: To change the actuation direction of the switch, remove the switch head. Change
the actuating control knob/mechanism to the desired actuation direction.
(Reference Figure 32)
OVER-TRAVEL LIMIT SWITCH (Fig. 30)
1. Find & assemble the adjustable limit switch kit as shown, including the Unistrut
mounting channel (Fig.31).
2. Locate and weld the Over-travel limit switch approximately 6” above the top level
limit switch kit and adjust position per steps 3 & 4 above.
NOTE: You will have to temporarily remove the upper level switch arm to be able
to travel past the upper level switch to the over-travel switch. Replace when done.
