INSTALLATION INSTRUCTIONS
C.J. ANDERSON INTERLOCK HG1 INSTALLATION (Refer to Figure 15)
The HG-1 interlock can be used at any level. It is important that the actuating roller be
properly adjusted so that that the actuating cam does not cause the actuating roller on
the interlock to over travel.
1. After the gate has been erected and tested for proper operation, the interlock can be
installed.
2. Mount the interlock to the gate post using the three 1/4”-20 UNC screws that have
been supplied as shown.
3. Mount the HG-1 strike weldment, attached to the gate panel, to the Unistrut channel
with two ¼”-20 UNC screws and the Unistrut nuts. Adjust the strike so that it is
seated in the interlock body and held in place when the actuating roller arm is in its
normal forward position. It is also necessary that the HG-1 strike weldment actuates
the switch arm to close the contact switch in the bottom of the HG-1 interlock.
4. Mount the actuating cam to the lift platform railing so that it moves the actuating
roller back into position to release the HG-1 strike weldment.
NOTE: When positioning the cam on the railing, do not allow the cam to interfere with
any objects during the full travel of the lift.
5. When the proper position is established, clamp or tack weld the cam in place.
6. Verify the operation of the cam, actuating roller, and the HG-1 strike weldment when
the lift platform moves to and from each level.
NOTE: The HG-1 strike weldment must activate the contact switch when the gate is
closed. Failure to activate the contact switch will prevent the lift from operating.
7. After assuring proper operation, weld the actuating cam into its final position.
8. Repeat this procedure for all levels using this type of interlock.
NOTE: This style of interlock does not need a gate status switch. The contact switch in
the HG-1 is the gate status switch.
