Three off 4 channel controllers were manufactured in wheeled flight cases, these were provided for large capacity, 2 speed Electric Chain Hoists. The Chain Hoists needed 32 Amp input power to each and as the hoists were 2 speed we fitted Buccaneer multi pin connectors.
A phase reverse switch was provided complete with indicator lights showing if the controller is correctly or mis phased.
The Controllers had Industrial type remote control handsets to allow hoists to be operated individually or together. Run and E-Stop button were also provided as were selection buttons for fast and slow speed.. To enable work to be carried out on site 2 off 220V and 110V, 1 phase outlets were provided complete with breakers.
