Hoists, Cranes, and other Lifting and material-movement-related equipment users must be
knowledgeable about the safe and proper use of this equipment and be aware of their responsibilities
as outlined in all applicable standards and regulations.
The ASME/ANSI B30 Standard contains provisions for the construction, installation, operation,
inspection, testing, maintenance, and use of cranes and other lifting and material-movement-related
equipment.
As OSHA’s, ASME, and ANSI standards state, a qualified person shall perform the installation, setup,
and operation of these units and equipment.
OSHA requires rated load tests for new and altered cranes. OSHA’s standard at 29 CFR 1910.179(k)
states:
Operational tests.
Before initial use, all new and altered cranes must be tested to ensure compliance with this section,
including the following functions:
Hoisting and lowering.
Trolley travel.
Bridge travel.
Limit switches, locking, and safety devices.
The trip setting of hoist limit switches shall be determined by tests with an empty hook traveling at
increasing speeds up to the maximum speed. The actuating mechanism of the limit switch must be
located so that it will trip the switch, under all conditions, in sufficient time to prevent contact of the
hook or hook block with any part of the trolley.
Rated load test. Test loads shall be at most 125 percent of the rated load unless otherwise
recommended by the manufacturer. Once you have performed a rated load test, paragraph
1910.179(k)(2) requires that test reports be placed on file where readily available to appropriate
personnel.”
To ensure safety and installation requirements, Prowinch requires a Load Test to be performed before
initial use for all Hoists, Winches, and Cranes, as well as other related components. Not fulfilling this
requirement is dangerous, could lead to equipment failure, and will automatically void the warranty.
The B30 Standard is intended to:
(a) Prevent or minimize worker injury and otherwise provide for protecting life, limb, and property
by prescribing safety requirements.
(b) Provide direction to manufacturers, owners, employers, users, and others responsible for proper
application.

(c) Guide governments and other regulatory bodies in developing, communicating, and enforcing
appropriate safety directives. The equipment covered by the B30 Standard is subject to hazards that
cannot be reduced by mechanical means but only by the exercise of intelligence, care, and common
sense. It is essential to have personnel involved in the use and operation of equipment that is
competent, careful, physically, and mentally qualified, and trained in the proper operation of the
equipment and the handling of loads. Serious hazards include, but are not limited to, improper or
inadequate maintenance, overloading, dropping, or slipping of the load, obstructing the free passage of
the load, and using equipment for a purpose for which it was not intended or designed.
Failure to Read, understand and follow the corresponding ASME B30 Standard information for your
Hoist and Lifting equipment may result in severe INJURY or DEATH. It is YOUR RESPONSIBILITY
to consider all risk factors and follow all the equipment-related ASME B30 standard, which comprises
the following volumes:
B30.1 Jacks, Industrial Rollers, Air Casters, and Hydraulic Gantries.
B30.2 Overhead and Gantry Cranes (Top Running Bridge, Single or Multiple Girder, Top Running
Trolley Hoist).
B30.3 Tower Cranes.
B30.4 Portal and Pedestal Cranes.
B30.5 Mobile and Locomotive Cranes.
B30.6 Derricks.
B30.7 Winches.
B30.8 Floating Cranes and Floating Derricks.
B30.9 Slings.
B30.10 Hooks.
B30.11 Monorails and Underhung Cranes.
B30.12 Handling Loads Suspended From Rotorcraft.
B30.13 Storage/Retrieval (S/R) Machines and Associated Equipment.
B30.14 Side Boom Tractors.
B30.15 Mobile Hydraulic Cranes.
B30.16 Overhead Hoists (Underhung).
B30.17 Overhead and Gantry Cranes (Top Running Bridge, Single Girder, Underhung Hoist).
B30.18 Stacker Cranes (Top or Under Running Bridge, Multiple Girder With Top or Under Running
Trolley Hoist).
B30.19 Cableways.
B30.20 Below-the-Hook Lifting Devices.
B30.21 Lever Hoists.
B30.22 Articulating Boom Cranes.
