6-3 Handling Precautions
1. Check to ensure that the load point is in the line with the hoist head.
2. When applying a load, it must be directly in line with hoist. Avoid off-center
loading of any kind.
3. Take up a slack load chain carefully and start load easily to avoid shock and
jerking of hoist load chain. if there is any evidence of overloading,
immediately lower the load and remove the excess load.
4. Do not allow the load to swing or twist while lifting.
5. Do not allow the load and/or attachments to bear against the hook latch
and/or hook tip. Apply load to hook bowl or saddle only.
6. The DUKE can be mounted upright as “motor up” in the traditional industry
situation or “motor down”, which has become standard in the entertainment
touring industry. Always ensure that it is clear whether the load chain shall
move or whether the hoist housing shall move. This does have effect on the
way power and control cables should be run.
