9. Crane may tip at less than rated loads if the surface is uncompacted or wet dirt, or
soft soil with frozen crust, thin or cracked pavement, or surface near a hole or ledge.
Always use adequate outrigger floats and/or cribbing. See page 2-13.
10. The operator shall not leave the controls while the load is suspended.
11. Always use adequate parts of load hoist line for lifting heavy loads.
12. Always be sure the rope is properly seated and wound level on hoist drum.
13. Keep hands away from load hoist rope when hoist is being operated.
14. Be sure at least five wraps of rope are left on the hoist drum to insure against rope
pulling out of its anchor.
15. Never wrap the hoist rope around a load. Always use approved rigging.
16. Avoid pinch points such as between a rotating turret and the cab or operator guard or
in access holes of a telescoping boom.
17. Avoid two blocking.
A. Stop raising hoist line before downhaul or hook block strikes boom tip plates.
B. Pay out hoist line while extending boom.
C. Maintain clearance between downhaul weight or hook block and boom tip
while booming down.
CAUTION
Keep hands out of Anti-Two-Block mechanism. Serious injury can result from
moving parts.
DANGER
Two blocking will abruptly stop boom lowering as well as hoist and extend. If
the boom is moving fast, this will cause the load to bounce or swing which
could cause loss of control of load or tipping.
