Specialty Models
Flex EX radios are available with special operational functions to provide even more control options.
A/B Selector Switch (AB)
A three-position selector switch allows one operator to switch operation between two trolley/hoists (A, B, or Both) that are located on a single bridge. The operator can easily identify which trolley hoist is active on the crane by the position of the selector switch.
Tandem Operation (T)
This system allows two operators to control two bridge cranes or trolley/hoists independently or simultaneously with the three position selector switch. One operator can maximize the capabilities and lifting power of two bridge cranes or both users can operate each bridge crane independently. (Available on 8- and 12-button models)
Receiver Select Operation (RS)
The system allows one operator to select multiple receiver units at one time, so one operator can control up to 2 bridges and 4 trolley/hoists simultaneously or independently. This simplifies installation by eliminating control festooning between the bridge and trolley/hoists and freeing up the trolley/hoist to run from one bridge to the next. (Available on 8- and 12-button models)
Flex EX Receivers
Flex EX receivers were designed with field installation and serviceability in mind. Receivers come prewired with 6’ of cable and mounting hardware allowing fast installation. Onboard diagnostic and output LEDs provide system status information useful when installing and troubleshooting. All components are easily accessible and field replaceable. The IP66 rated fully sealed receiver enclosures provide you with confidence and protection in the harshest indoor or outdoor environments.
