OPERATION OVERLOAD PREVENTION
!
1. Know the weight of the load.
2. Load radius will increase when the load is lifted. Reduce radius at start of lift
to allow for this.
3. Know the weight of hook, and rigging.
4. Know boom length, jib length, parts of line and operating area.
5. Use next lower rated capacity when working at boom lengths or radius
between the figures on the rated lifting capacity chart.
6. Never lift a load without knowing whether it is within the rated capacity.
7. Never operate with anything other than recommended counterweight.
Unauthorized reduction or additions of counterweight constitute a safety
hazard.
8. Do not lift loads if winds create a hazard. Lower the boom if necessary. See
the Rating Chart Manual for possible restrictions.
9. Avoid side loading.
10. Never let the load or any other object strike the boom.
11. Release load slowly, be sure boom never tightens against back stops. (Lattice
Boom).
12. Place the boom point directly above the load when lifting.
13. Be sure loads are freely suspended.
