Limited work space, multiple obstacles, and heavy parts lead to ergonomic problems. Restricted
power sources and underground environmental conditions limited the available equipment to
perform the tasks. The end-user was looking for a solution to improve operator ergonomics as
well as the overall efficiency of this maintenance process.
Maintenance personel were required to
change out failed rollers on a mine grade conveyor system
running several miles underground. Personnel had to lift
the conveyor belt for access to the rollers and then reach
across the conveyor support structure to remove the 72 lb.
Custom designed Rail Car Manipulator with roller
flow rack system, manipulator arm for roller removal and
placement, a special jib and hoist to lift and hold the conveyor
belt to facilitate access to the rollers, including a dump
station with tilt feature for the expired rollers. Using a tamper
car provided by the end-user, Positech designed,
manufactured, assembled and mounted a complete integrated
system with the power source generated by and pulled along
the tracks accompanying the conveyor, by the end-user's
locomotive. The material handling solution included adjustable
flood lights and increased the efficiency and ergonomics for
this difficult maintenance task.
