generator, which does not rotate and is rigidly
mounted to the idler support structure. The
generator is sealed from fugitive material and
forms an integral unit independent of the
conveyor roll. The bearings of the generator are
able to handle the conveyor belt load, as they are
of similar size to the roller.
On conveyors that already employ Martin TracMount Idlers™ (TMI) outside of a loading zone,
installation is as easy as removing the wing slide
on one end and replacing it with the Roll
Generator slide, a two-minute procedure. The TMI
design is particularly well-suited to tight spaces,
with just 203 mm of clearance needed for 152
mm rolls. While standard rollers can be difficult
to replace without ample clearance, the slidein/slide-out roller frames allow quick service,
without the need to raise the belt or remove
adjacent idlers.
“The generator can also be installed on its
own mount or on other existing support
structures, such as a belt tracker,” added
Harrison. “All components to ‘condition’ the
power to a steady 24v DC are enclosed in a
protective cabinet, typically mounted directly on
the idler support slide.”
The reliable power supply allows conveyor
system designers to equip them with devices
such as weigh scales, proximity switches,
moisture sensors, pressure switches, solenoids
and relays, as well as timers, lights and even
additional safety mechanisms. Wireless
communication can be used to transmit directly
to a central controller, giving operators a costeffective way to access data that has not been
readily available in the past.
“The capability to store power in a small
battery bank is already in development,”
Harrison added. “This will allow the
generator to produce five to ten times
higher amperage for short periods to
power higher-wattage devices.”
Doppelmayr Transport Technology
provides solutions for all types of bulk
material and unit load transport
requirements with a wide range of
technically proven systems. It is a
pioneer and technology leader in
ropeway engineering, and has built
more than 14,700 passenger and
material transport systems in 90
countries. The company is an expert in
material handling solutions, and, as
one can expect from a company which
has established a long tradition of
excellence in ropeway engineering, the
systems are especially well suited for
difficult terrain or to cross obstacles.
Ropeways effortlessly span valleys
and cross obstacles, while transporting
their load reliably and safely.
