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.
