LIFTING:
1. Always refer to Crane Capacity Chart in operator's compartment before handling
load. Do not exceed load ratings. Under some conditions the standard capacity
ratings cannot be recommended and must be adjusted downward to compensate for
special hazards, such as weak supporting ground, wind, hazardous surroundings,
operator inexperience, etc. The weight of the load should always be known.
2. Be careful to prevent load swinging. A swinging load can cause instability or loss of
control of the load. Be aware that the Anti-Two-Block System and the Rated
Capacity Limiter can cause sudden stopping of boom movement, which can cause
the load to swing. Move the boom slowly whenever these systems might stop the
boom.
3. Do not allow anyone
to put any part of his
body under a load.
The load may lower or
fall if there are
damaged parts in the
crane. Also, the load
may drop a short
distance due to
thermal contraction of
the hydraulic oil in the
cylinders.
4. Do not use crane to drag loads sideways. Do not use crane to raise grounded or
fixed load by using Boom Raise function.
5.
6.
7. Level the crane before lifting. A small incline will significantly reduce the capacity.
Use appropriate cribbing under the outriggers for leveling. All tires must clear the
ground to use the ON OUTRIGGERS ratings.
8. Always use outriggers if possible. If you must lift on rubber, keep the load as close
to the ground as possible to prevent tipover. Move the load very slowly and use tag
lines to prevent load swinging.
