• If, during the course of repairs, it becomes necessary to move the crane, it shall be the responsibility of
the crew leader to ensure that all personnel located on and within the operational area of the crane are in
a safe position, out of harm’s way. In addition the crew leader shall ensure all tools and materials are
stowed or tightly restrained before the crane is moved
• When the repair work is completed, the crew leader shall see that all crew members are off the crane
before he or she closes the main switch
• If more than one person is on board the PRC crane, one person shall be made responsible for seeing that
all workers are off the crane before the portable remote controller is returned to operational use
Remote Controlled Crane Under Repair
• All persons operating other cranes on the same or adjacent runways shall be notified before anyone
boards the subject crane. Such notification should include limitations of adjacent crane movement while
others are on board
• PRC cranes which have been pre-positioned for repairs and cannot be moved should be protected
against being bumped by other cranes on the runway. Suitable bumpers adequate for the job should be
installed on the exposed sides of the crane under repair and as far away from the crane as possible, with
a minimum distance of 20 ft (approximately 6.1 m). The location of these bumpers shall be indicated by
red lights so that they are clearly visible to other persons operating cranes traveling on the same runway.
When it is impossible to use bumpers for protection, red lights shall be placed in clear view of other
persons operating cranes on the same runway to indicate the restricted travel zone. It is desirable that
such red lights be located a minimum of 20 ft (approximately 6.1 m) from the crane under repair
• All operators of cranes on the same runway must be informed of the repair work, thoroughly instructed as
to what their conduct should be for the duration of said repairs, and informed when repairs are completed
• When there is a runway adjacent to the runway on which the crane is being repaired, and if any hazard
exists that involves the repairmen, red lights shall be placed in clear view of persons traveling on the
adjacent runway to indicate the restricted travel zone. It is desirable that such red lights be located a
minimum of 20 ft (approximately 6.1 m) from the crane under repair. When it is necessary to operate
cranes on adjacent runways, such cranes shall come to a full stop before entering the restricted area.
Cranes traveling on adjacent runways may only proceed through the restricted area when permission has
been received from a signalman posted for this purpose
• Access of persons to and from the crane being repaired shall be under the control of the repair crew
leader
• The floor area below the point where crane repairs are being made shall be roped off and posted with
danger signs
• Handling of all small tools and materials, etc., from ground level to workers above shall be accomplished
through the use of hand lines. Tools, materials, etc., shall not be tossed from the crane to the ground
level and vice versa
• If crane repairs make it necessary for crew members to work on areas of the crane other than those
protected by standard handrails, such crew members shall wear approved safety belts
• If it is necessary to move the crane to check the performance of operation, the crew leader shall
designate who remains on the crane. The crew leader shall ensure that all personnel located on and
within the operational area of the crane are physically located in a safe position, out of harm’s way. In
addition, the crew leader shall ensure all tools and materials are stowed or tightly restrained before the
main switch is closed and the crane is put into operation
• Upon completion of repairs, it is the crew leader's duty to personally ensure that each person has left the
crane and is clear before he or she removes the lock above the main switch and the crane is put back in
operation
