The system uses the moving conveyor to generate electricity,
powering a compressor to maintain optimum blade pressure.
Sensors detect whether the belt is loaded, automatically relieving
tension when the conveyor is empty to help minimise wear.
New automated tensioner offers precision, extends service life
The Automated Blade System
(ABS) can be supplied in two
variations, for locations with or
without an existing power source.
On sites with available power, the
company will offer a 120/240V AC
version of the system to power
the system’s 24V compressor. In
facilities able to supply power and
compressed air to the head pulley,
Martin designs the system so
that the panel simply handles the
‘smart’ portion of engaging and
disengaging the cleaner blade.
For locations lacking convenient
power access, the self-contained
version uses the moving conveyor
to generate its own electricity,
Martin Engineering has
introduced an automated
pneumatic tensioning system
for belt cleaners that delivers
precise monitoring and tensioning
throughout all stages of blade
life, reducing labour required to
maintain optimum blade pressure
and extending the service life of
both belt and cleaner.
Equipped with sensors to
confirm that the belt is loaded and
running, the system automatically
backs the blade away during
stoppages or when the conveyor
is running empty, minimising
unnecessary wear to both the belt
and the cleaner.
which powers a small 24V DC air
compressor to maintain optimum
blade pressure always.
Built around the patented
Martin Roll Generator, the new
self-powered version includes
a proprietary storage system
developed specifically for this
application. With lead acid
batteries to hold the energy,
the system can produce ample
power to drive the compressor,
which maintains pressure in the
reservoir to re-tension the cleaner
as needed.
The generator can produce up
to 40W at maximum speed, which
is sufficient to run components
such as weigh scales, proximity
switches, moisture sensors,
solenoids and relays, as well as
timers, lights and safety devices.
The batteries, which re-charge
during normal running of the belt,
supply the extra energy to power
the compressor.
Wireless communication can
be used to transmit directly
to a central controller, giving
operators a cost-effective way
to access data that has not been
readily available in the past.
The system’s regulated outputs
can be individually adjusted to
the desired pressure to tension
multiple cleaners.
MB Crusher’s smallest bucket gets an upgrade
system has been added to
simplify and speed up on-
site maintenance operations.
“All our products undergo
MB Crusher’s smallest model of
crusher bucket, the BF60.1, has
been upgraded and the fourth
generation is now available.
The new series 4 BF60.1 is
suitable for heavy equipment
from 7.25 tonnes upwards. This
version of the crusher bucket has
been updated and strengthened,
both structurally and technically.
A restyling of the BF60.1’s
structural layout allows for
more agile movement and
increased speed during crushing
operations, facilitating its use
on the excavator. Parts that
are subject to stress have been
reinforced, new regulation
options have been added, the
dimension range of crushed
material has been extended
and a new centralised greasing
continuous testing and
experimentation to improve
them and render them more
efficient in the several types
of work sites that our clients
deal with every day,” says Diego
Azzolin, head of MB Crusher
design and production.
The new series 4 BF60.1 is suitable for heavy
equipment from 7.25 tonnes upwards.
