damage to the sheaves, or causing the wire rope to fail,
dropping the lifting device to the ground and possibly injuring
personnel working below.
Caution must be used when lowering the boom, extending
the boom or hoisting up. Let out load line(s) simultaneously
to prevent two-blocking the boom tip(s) and the hook block,
etc. The closer the load is carried to the boom nose the more
important it becomes to simultaneously let out wire rope as
the boom is lowered. Keep load handling devices a minimum
of 42 in (107 cm) below the boom nose at all times.
Two-blocking can be prevented. Operator awareness of the
hazards of two-blocking is the most important factor in
preventing this condition. An Anti-Two-Block System is
intended to assist the operator in preventing dangerous two-
block conditions. It is not a replacement for operator
awareness and competence.
Never interfere with the proper functioning of operational
aids or warning devices.
Work Area Definition System (WADS) (If
Equipped)
If your crane is equipped with a WADS, you must read and
understand the manufacturer’s Operator’s Manual before
operating the system. Become familiar with all proper
operating procedures and with the identification of symbol
usage.
The work area definition system is intended as an aid to the
operator. It is not a substitute for safe crane operating
practices, experience and good operator judgements.
CRANE STABILITY/STRUCTURAL
STRENGTH
To avoid death or serious injury, ensure that the crane is on a
firm surface with load and crane’s configuration within
capacity as shown on the crane’s Load Chart and notes.
Ensure all pins and floats are properly installed and outrigger
beams are properly extended before lifting on outriggers. On
models equipped with outriggers that can be pinned at the
mid-extend position (vertical strip, if applicable), the
outriggers must also be pinned when operating from the mid-
extend position.
Use adequate cribbing under outrigger floats to distribute
weight over a greater area. Check frequently for settling.
