CRANES, HOISTS, RIGGING EQUIPMENT, AND ELEVATORS
6.1 Cranes and Hoists
Due to the potential for injury to personnel and damage to equipment, periodic inspection and maintenance
of cranes and hoists is very important. A preventive maintenance and inspection program based on the
manufacturer's recommendations and applicable industry standards should be established for all cranes,
hoists, or other lifting devices. This program should be well documented with detailed records of the
inspections and maintenance performed on the equipment.
Section 18 of Reclamation Safety and Health Standards lists the requirements for the installation and
maintenance of hoisting equipment for Reclamation forces. The American National Standards Institute
(ANSI) publishes the following standards that may be useful in setting up an inspection and maintenance
program for cranes and hoists: B30.2 "Safety Standard for Overhead and Gantry Cranes"; B30.5 "Safety
Code for Crawler, Locomotive, and Truck Cranes"; B30.10 "Hooks"; B30.11 "Monorails and Underhung
Cranes"; and B30.16 "Overhead Hoists (Underhung)."
6.2 Ropes, Slings, Chains, and Rigging Hardware
Section 17 of Reclamation Safety and Health Standards provides information on ropes, slings, chains, and
accessories and their safe use. The
Rigging Manual published by the Construction Safety Association of
Ontario, 74 Victoria Street, Toronto, Canada, M5C2A5 has been designated as the Reclamation Rigging
Manual. This publication provides information on safe rigging, load capacities of slings and other rigging
equipment, and the inspection of wire rope and slings. The
Rigging Manual should be used as a guide in
determining whether rigging practices are safe and in conformance with industry-wide practices; and while
its use is recommended, it is advisory in nature and intended to complement the safety requirements of
section 17 of Reclamation Safety and Health Standards. ANSI standard B30.9 "Safety Standard for
Slings" also may be helpful in the use and inspection of slings.
Prior to any lift, all of the rigging should be inspected to ensure that it is safe to use. Defective equipment
that is repairable should immediately be clearly marked as unsafe and removed from service. Repairs
should be made by the manufacturer or in accordance with the manufacturer's written instructions.
Repaired equipment shall be tested at twice their rated safe working load. Defective equipment that is not
repairable should be cut in half or otherwise rendered unusable to ensure it will not be used. Capacity
charts should be consulted; and all variables, such as sling angle, should be considered, to assure that the
rigging hardware's rated capacity is not exceeded by the load being lifted.
6.3 Shop Fabricated Lifting Devices and Rigging Hardware
Shop fabricated lifting devices or rigging hardware, including supports or components of a hoist or lifting
device, shall not be used unless designed and certified by an engineer qualified in this field and tested at
twice the rated safe working load. All lifting devices and rigging hardware shall be designed with a 5:1
factor of safety and in accordance with any applicable ANSI standard.
