Assembly and Disassembly
Accidents during assembly and disassembly of lattice boom and tower cranes are one of the major causes of crane-related fatalities.
These sections are designed to prevent such accidents by requiring safe Assembly and Disassembly procedures for lattice boom and tower cranes. Hydraulic-boom cranes are not generally assembled on-site, but these sections contain some provisions, such as the requirement (Standard 1404(q)) for proper setting of outriggers and stabilizers, which apply to cranes with hydraulic booms.
Required Procedures
When assembling or disassembling a crane, you must comply with either manufacturer or employer procedures, which must be developed by a qualified person.
The qualified person must ensure that, at a minimum, procedures include the following:
- prevention of unintended dangerous movement or collapse of any part of the equipment,
- provision of adequate support and stability of all parts of the equipment, and
- mitigation of employee exposure to unintended movement or collapse of equipment while involved in the assembly and disassembly operation.
Regardless of which of these options you choose, you must follow any manufacturer prohibitions that apply to the assembly and disassembly operation.
