Martin Engineering has designed a family
of conveyor tail pulley protection
products that are intended to reduce
fugitive material entrapment under virtually
any belt conditions. The equipment
provides consistent blade pressure
across the belt plane, producing
little wear on the splice, with specific
designs for regular- and heavy-duty
applications, reversing belts and wing
pulleys. The result is improved conveyor
performance, as well as prolonged
belt and tail pulley health, reducing
maintenance and contributing to a
safer work area. To fight the damaging
effects of fugitive material on singledirection
belts, the Martin Torsion
VPlow is engineered with a unique
spring-loaded suspension system that
allows the plow to rise and fall with
fluctuations in belt tension and travel.
Attached with dual steel crossbars bolted
to the conveyor frame a few feet
from the tail pulley, the unit is secured
by two heavy-duty safety cords. Three
torsion arms system adjust independently,
maintaining consistent pressure
for effective cleaning in all stages of
blade wear.
For less extreme service environments,
the Martin VPlow HD offers an
economical solution designed for medium-
to heavy-duty applications, featuring
a durable 60 Shore A durometer
nitrile rubber blade that delivers 2 in.
(5 cm) of wear life. The unit is suitable
for non-reversing belt speeds as high as
900 fpm (4.6 m/sec). For conveyor systems
running at faster speeds or carrying
heavy loads, the Martin VPlow XHD
protects non-reversing standard tail
pulleys even at belt speeds exceeding
1,000 fpm (5.08 m/sec). Its 1.25-in.
(3.18-cm) thick urethane side blades
deliver 3 in. (7.62 cm) of wear.
The Martin Durt Dozer plow is designed
to handle standard tail pulleys or
wing pulleys on single-direction belts. It
sits across the belt at a 45° angle and
uses its curved blade to remove fugitive
material from the inside surface of belts
traveling at speeds up to 700 fpm (3.5
m/sec). The company offers 11 different
sizes to accommodate single-direction
belts from 18 in. (45.7 cm) to 96 in.
(243.5 cm) wide.
