BOOM DISASSEMBLY SAFETY
NOTE: The term “boom” used in the following instructions
applies to all lattice attachments (for example,
boom, fixed jib, luffing jib, and mast).
Safe handling of lattice booms during disassembly is a
primary concern for preventing serious or fatal injuries. A
boom can collapse during disassembly if workers fail to
observe safe working practices.
Accidents during boom disassembly usually result from one
of three primary causes:
• Workers are not familiar with equipment or are not
properly trained.
• The disassembly area is not suitable.
• Safe procedures are overlooked because not enough
time is allocated for the task.
General
See Figure 2-3 for a safety decal example.
Safety decals are placed near the connections on each
boom section. See Boom Disassembly Decal Drawing for
more information.
Workers involved with boom disassembly shall be trained
and experienced in the operation and disassembly of
construction cranes. The workers shall read and thoroughly
understand the assembly and disassembly instructions in
the Boom Assembly Drawing and in the assembly and
disassembly instructions in Section 4 before beginning
disassembly. Anyone who has a question should ask for an
explanation. One worker who does not fully understand or
fails to follow correct procedures can be killed or seriously
injured or endanger other workers.
Location
Select a suitable location for boom disassembly. It must be
firm, level, and free of obstructions. It should have enough
open space to accommodate the crane and the length of
boom. Also take into consideration whether an assist crane
or other equipment is required. If possible, secure the area to
keep unauthorized personnel and vehicles away.
FIGURE 2-3
DANGER
Collapsing Boom Hazard!
Prevent death or serious injury when disassembling boom
sections. Read and adhere to these instructions.
WARNING
Falling Boom Hazard!
The crane can tip or boom can collapse if excess boom is
cantilevered. Never cantilever more boom than specified
in Boom Assembly Drawing.
