Cranesafety 4 01/2001, CATTRON - THEIMEG
TM
4. TRAINING CHECKLIST FOR OPERATORS OF REMOTE CONTROLLED CRANES,
continued.
As a minimum, Portable Remote Control Operators shall:
+
observe signal lights on crane.
+
avoid striking any obstructions.
+
check for proper clearance of lifts or hooks before moving bridge or trolley.
+
properly store the portable remote controller when not in use.
+
know how to properly transfer the portable remote controller to another person.
+
report unsafe or unusual operating conditions.
+
use caution in approaching bridge or trolley end-stops.
+
know the crane’s capacity.
+
keep body clear of lifts, avoiding ‘pinch’ points.
+
Inspect cables and hooks.
5. THE OPERATING AREA FOR THE REMOTE CONTROLLED CRANE.
+
Unobstructed aisles between equipment, stock, etc. shall be maintained for the PRC
crane operator's movement. These aisles should be a minimum of 3 feet wide (1m) or
per local regulations.
+
PRC crane operators shall always position themselves in a safe location with the best
view of the crane they are controlling and never operate the crane blindly. They shall
always keep the crane and load in sight, staying as close as practical to the crane load
while maintaining a safe harms-way distance. Operators shall never position
themselves or others underneath the load or in a ‘pinch’ point.
6. THE HAND-HELD PORTABLE REMOTE CONTROLLER.
+
Typically, the portable remote controller incorporates a Push-To-Operate (PTO) bar
or START button, and its motion switches are spring return to OFF. The PTO bar
acts as a guard for these switches to prevent movement of the crane if one of the
switches is accidentally bumped. These switches and the PTO bar must never be
mechanically blocked in any ‘ON’ position.
+
Using the power ON/OFF switch(es), the portable remote controller shall be switched
‘OFF’ when not in use. When the controller is equipped with a STOP button, it shall
be set to the ‘STOP’ position before switching off power to the controller. In
addition, if equipped with a key, the key should be removed after use and kept in a
secure location.
+
A prescribed, controlled, storage space shall be provided for portable remote
controllers. All controllers shall have their batteries removed and be placed there
when not in use. This precaution is intended to prevent unauthorized personnel from
operating the remote controlled crane.
