Section 2 - Radio Controlled Crane Safety (continued)
Telemotive TR12 inteleSmart Receiver Instruction Manual – 03/01/07

The operator should be trained in transferring radio
transmitter to another person.
The operator should be trained how and when to
report unsafe or unusual operating conditions.
The operator should be trained how to exhibit caution
in approaching bridge or trolley bumpers.
The operator should know equipment capacity.
The operator should be trained in making lifts below
floor level.
The operator should be trained in making side pulls.
The operator should know how to keep himself and
other people clear of lifts and to avoid "pinch" points.
The operator should know cable and hook inspection
procedures.
The operator should know procedures for testing
hoist, trolley, and bridge brakes.
2-5. Operating Area.
Aisles between equipment, stock, etc., should be free
of obstructions so the crane operator can move freely.
These aisles should be a minimum of three feet (one
meter) wide, or meet local regulations.
Crane operators should always position themselves
for the best view of the crane they are controlling.
The crane should never be operated blindly. The
operator should stay as close to the crane load as
possible. Operators should never position themselves
in a "pinch" point.
2-6. Transmitter Unit.
Transmitter switches should never be mechanically
blocked ON or OFF for any crane motion. When not
in use turn the transmitter OFF. A secure storage
space should be provided for the transmitter unit and
the transmitter unit should always be placed there
when not in use. This precaution will prevent
unauthorized people from operating the crane.
Spare transmitters should be stored in a secure
storage space and only removed from the storage
space after the current transmitter in use has been
turned OFF, taken out of the service area and
secured.
Before putting the transmitter in service the
transmitter unit should be inspected for any damage
or excessive wear. Units with, but not limited to, any
of the following: broken housings, switches or
handles, missing battery doors, switch boots or
switch knobs should be repaired before putting into
service.
2-7. Operating The Crane.
2-7.1. Pre-operation Test.
At the start of each work shift, or when a new op-
erator takes control of the crane, operators shall do as
a minimum the following steps before making lifts
with any crane or hoist:
Test the upper-limit switch. Slowly raise the
unloaded hook block until the limit switch trips.
When checking limit switches the hoist should be
centered over an area free of personnel and
equipment.
Visually inspect the hook, load lines, trolley, and
bridge as much as possible from the operator's
station; in most instances, this will be the floor of the
building.
The bridge and trolley brakes should be tested. On
transmitter units equipped with two or more speeds,
use the "lowest" speed when testing braking devices.
When lifting maximum loads, the crane operator
should test the hoist brakes by raising the load a few
inches from the floor. If the brakes do not hold, the
load should immediately be lowered to the floor.
If provided, test the lower-limit switch.
Test all warning devices.
Test all direction and speed controls for both bridge
and trolley travel.
Test all bridge and trolley limit switches, where
provided, if operation will bring the equipment in
close proximity to the limit switches.
Test the transmitter emergency stop.
Test the hoist brake to verify there is no drift without
a load.
If any crane or hoist fails any of the above tests notify
the supervisor and lock out and tag for repair.
