2. Radio Controlled Safety
Flex radio remote control systems should be operated by persons with a 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, any
severe or debilitating illness, or 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. Always check the transmitter handset for any damage that might inhibit proper crane operation
prior to 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 33).
4. Check the Status LED on the transmitter for any signs of irregularities (refer to page 33).
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 store 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 21 and page 32 of this manual.
