2. Radio Controlled Safety
Flex radio remote control system should be operated by persons with sufficient amount of knowledge
and skill in crane operation and safety. Persons being trained to operate a radio remote controlled crane should
possess the knowledge of all hazards peculiar to radio remote controlled crane operation, ability to judge
distance and moving objects, equipment capacity and radio remote controlled safety rules. Radio remote
controlled cranes should not be operated by any person with insufficient eyesight, hearing, illness, and under
influence of drugs and medications that may cause loss of crane control.
Below are some general operating safety tips that should be strictly followed when operating a radio
remote controlled crane.
1. Prior to crane operation always check the transmitter handset for any damage that might inhibit proper
crane operation.
2. Always check if the red emergency stop button is working properly prior to crane operation.
3. Check the Status LED on the transmitter for any signs of low battery power (refer to page 37).
4. Check the Status LED on the transmitter for any signs of irregularities (refer to page 37).
5. The crane limit switches should be checked prior to crane operation or at the beginning of each shift.
When checking limit switches the hoist should be centered over an area free of personnel and
equipment.
6. If the power to the crane is removed, the operator should turn off the transmitter power immediately
until the power to the crane is restored.
7. If the crane fails to respond properly to operator’s command the operator should stop operation, turn
the transmitter power off, and then report the condition to their supervisor.
8. The transmitter power should be turned off after each use. If the transmitter handset is not in use always
turn the power off and stored it in a safe or designated location. Never leave the transmitter handset
unattended in the working area.
9. Make sure the system is not set to the same channel as any other Flex systems in use within a distance
of 300 meters (900 feet).
10. Never operate a crane or equipment with two transmitter handsets at the same time unless they are
programmed with “Pitch & Catch” function. For information on the “Pitch & Catch” feature, please
refer to page 25 and page 36 of this manual.
