4. When first operating the hoist and trolley it is recommended that the motors be driven slowly in both directions for
a few minutes.
5. Operate the trolley along the entire length of the beam.
6. Check operation of limit devices.
7. Check that trolley (if equipped) and hook movement is the same direction as arrows or information on the pendant
control.
8. Check to see that the hoist is securely connected to the overhead crane, monorail, trolley or supporting member.
9. Check to see that the load is securely inserted in the hook, and that the hook latch is engaged.
10. Raise and lower a light load to check operation of the hoist brake.
11. Check hoist operation by raising and lowering a load equal to the rated capacity of the hoist a few centimeters off
the floor.
12. Check to see that the hoist is directly over the load. Do not lift the load at an angle (side pull or "yard").
13. Inspect hoist and trolley performance when raising, moving and lowering test load(s). Hoist and trolley must
operate smoothly and at rated specifications prior to being placed in service.
• Only allow personnel instructed in safety and operation of this product to operate the hoist and trolley.
• The hoist is not designed or suitable for lifting, lowering or moving persons. Never lift loads over people.
Hoist Controls
Two Lever Pendant
Two lever pendants provide operation of the hoist only.
For units with powered trolleys a four lever pendant is
required. Refer to manufacturers information on Pendant
Throttle Handle Assemblies for two and three motor
functions.
The pendant control throttle uses two separate levers for
hoist operation.
Direction of hook travel is controlled by whichever lever
is depressed.
1. To start hoist operation press the "ON" button.
2. To operate hoist, press the "UP" or "DOWN" con-
trol lever.
3. In the event of an emergency all hoist operation can
be stopped by pushing the emergency stop button.
This will prevent air from reaching the hoist motor
which will stop any movement.
4. The "ON" button must be pushed to restart the
hoist after the "Emergency Stop" button has been
used.
• The hook latch is intended to retain loose slings or devices under slack conditions. Caution must be used to
prevent the latch from supporting any of the load.
