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"
control 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 "OFF" button will also stop hoist operation
if pressed.
5. The "ON" button must be pushed to restart the
hoist after the "Emergency Stop" or "OFF"
button have 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.
