•
Warning signs and barriers shall be utilized on the floor beneath the hoist, crane or lifting system where overhead
maintenance, repair or inspection work creates a hazardous area on the floor beneath the hoist, crane or lifting
system.
•
If the crane runway or monorail remains energized because other hoists or cranes are on the same runway or
monorail are in operation, rail stops or a signal person(s) shall be located full-time at a visual vantage point for
observing the approach of an active hoist(s) or an active crane(s) to prohibit contact by the active hoist(s) or
crane(s) with the idle hoist or crane, persons performing maintenance, repair or inspection and equipment used
in performing maintenance, repair or inspection.
•
A guard or barrier shall be installed between adjacent runways for the length of the established work area to
prevent contact between persons performing maintenance, repair, or inspection and a crane on the adjacent
runway.
•
Safe Access to the hoist, crane or lifting system, such as, scaffolding, work platforms, etc., shall be provided for
personnel that will perform maintenance, repair or inspection. I personnel are required to work at elevations in
excess of 6 feet above floor or ground level, a fall prevention policy and procedures shall be developed,
documented and implemented by the owner/user.
•
After maintenance, repair, or inspection work is completed, and before the hoist, crane or lifting system is
returned to normal operation:
o
Any guards on the hoist, crane or lifting system that were removed to perform maintenance, repairs or
inspection work shall be reinstalled.
o
An safety devices on the hoist, crane or lifting system that were deactivated to perform maintenance,
repair or inspection work shall be reactivated.
o
Any parts that were replaced and other loose material shall be removed.
o
All equipment used in the maintenance, repair or inspection work shall be removed.
•
Warning signs, barriers and guards shall be removed only by authorized personnel.
•
Lock and tag on the main switch (disconnect) of the hoist, crane or lifting device shall be removed only by the
person that locked and tagged the main switch originally, or an authorized person.
6.1.1
Inspection Records
Dated inspection reports and records of the condition of critical components such as load chain, hooks and brakes
observed during frequent and periodic inspections should be established. This record should also record replacement,
maintenance and repair information. Use of this recorded information will allow a preventative maintenance program to
be established for replacement of wearing components on a regular basis, thereby eliminating ore reducing
unscheduled downtime situations. These records should be stored where they are available to personnel involved with
the inspection, maintenance, or operation of the hoist.
6.2
Inspection Classification
Many factors influence the inspection and preventative maintenance programs required for the hoist. Frequency and
severity of service and material handled, local environmental conditions and various applicable codes are some of the
factors that the user must consider and adjust the inspection and maintenance programs outlined in this section to meet
the specific conditions.
Inspection procedure for hoists in regular service is divided into two general classifications as outlined in ASME B30.16.
These two general classifications are based upon the intervals at which the inspections should be performed. The
intervals are dependent upon the nature of the critical components of the hoist and the degree of exposure the hoist
components and parts to wear and deterioration. The degree of exposure is dependent upon hoist activity and severity of
hoist service. Environmental conditions in which the hoist operates are also important considerations for the user when
adjusting hoist inspection and maintenance programs to local conditions. Frequency of inspection and maintenance
