Two-blocking will abruptly stop boom lowering and boom swing, 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.
18.The amount of counterweight supplied with this crane should never be changed.
Unauthorized addition of counterweight in the field to increase lifting ability constitutes a
safety hazard.

side of turntable for boom clearance.)
20. If boom should accidentally contact a power line, keep ground personnel away from
crane. Stay in the crane until the power source is de-energized. Move the crane away
from electrical hazard, if this does not cause new hazards. If it is absolutely necessary
to leave the crane,
jump clear of the crane with both feet together. Hop away from the
crane with feet together.The ground surface may be energized.
