Users must be knowledgeable about the safe and proper use of Hoists, Cranes, and other Lifting
and material-movement-related 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-rela-
ted
equipment.
As OSHA’s, ASME, and ANSI standards state, a qualied 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 sucient 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 recom-
mended by the manufacturer. Once you have performed a rated load test, paragraph
1910.179(k)(2) requires that test reports be placed on le 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
fullling 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.

SAFETY BULLETIN

V.01.23 [LM]

(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 qualied, 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

Do not allow chain to run dry
Lubricant dramatically increases the life of the load chain. Weekly lubrication and cleaning are satisfactory, but under hot, dirty,
and extreme conditions, it may be necessary to clean the chain at least once a day and lubricate it several times between
cleanings. Apply sucient lubricant to obtain natural runo and full coverage, especially in interlink areas.
Suspension pins should be lubricated at least twice per year for normal usage; more frequently for heavier use or severe condi-
tions.
