Conveyor belt holding devices

Flights of the conveyors installed in the mine roadways with inclination angles of 10 and more degrees are equipped with safety casing of the carrying run. The safety casing consists of break frame installed hingedly on two axes with their arms mounted on connection. During the belt motion under the action of the drive pulling load it inclines the break frame forward (along the belt), which touches the belt with support plate only. If the belt starts to move invertedly, the break frame together with the belt will move until its stop into the lock pin. The belt will lift above the roller and will lie on the scraper of the break frame.
