The next three decades found MHE expanding and increasing their market share. They added Apron Conveyors and an array of specially designed conveyors for the most severe operating conditions. In the mid 70's, Jervis B. Webb Company purchased MHE to expand their product line and soon consolidated the operation of Chicago to Marietta, Georgia.
Sprinkler Locations For Protecting Conveyor Belts. Automatic closed head sprinklers are adequate in most circumstances. However, provide automatic open head water spray systems to protect conveyor belts and drives when conveyors have of the any following characteristics: • Conveyor belts over 4 ft (1.2 m) wide. • Stacked conveyor belts.
A standard belt conveyor system has a head pulley, tail pulley, idler rollers, belt, and frame. Head Pulley. The head pulley is coupled with the actuator and the electric motor. It drives the conveyor, acting as the pulling force. The head pulley is located at the point that the conveyor offloads, known as the discharge end of a belt conveyor.

The backstop is often specified on multi-drive systems, such as large inclined conveyors, where two or more backstops share the reverse load. The torque limiting function is performed through a multi-disc brake working in oil. This solution not only provides for a high torque density of the complete unit, but also ensures that the set slip ...
A Belt Change Out in a Shift The 2,200-ft refuse conveyor at a West ia prep plant had reached the end of its life and needed to be replaced.
