The Hubbell Mid-Size Transmitter is for use  
with Hubbell microcontroller receivers. It is  
used for the remote control of overhead  
cranes, locomotives and other moving  
equipment. The transmitter is fully self  
contained with battery, controller board, rf  
board, antenna, switches and indicators in a  
small, lightweight, rugged plastic case. The  
transmitter is equipped with either a 72–  
76 MHz or 450–470 MHz rf board and  
antenna, per customer order.  
Levers similar to a crane cab master controller  
are provided for the control of bridge, trolley,  
main hoist, and auxiliary hoist motions. Each  
control switch has a positive detent  
arrangement to provide operator feedback of  
individual speed points. Additional toggle or  
spring return switches, key switches or  
pushbuttons can be provided for the control of  
other functions such as horn, brakes, magnets,  
tongs, etc. A Master Key Switch is provided  
for turning battery power on and off to the  
transmitter control circuit. A Run/Emergency  
Stop toggle switch is provided for quick stop  
in case of emergency. This switch must be in  
the Run position for the transmitter to operate.  
The battery is a 12 volt Ni-Cad module  
having the capacity to power the transmitter  
for two work shifts (20 hours) when fully  
charged. It is easily removed for quick  
recharging in the battery charger.  
Each transmitter comes with a battery pack,  
two keys for the Master Switch and a fully  
adjustable shoulder harness.
