In May 2021, the specialists of the ADAMANT company manufactured and shipped a ratchet stop part 2Bu 07856 SB for JSC YUZHNIY GOK.
The ratchet stop consists of a ratchet wheel mounted on a toothed clutch of the frame, an articulated lever mechanism with ratchet pawls and an electromagnet.
Ratchet stop specifications:
height………………………………………………………………………………………2255mm
width……………………………………………………………………………………….3080
weight……………………………………………………………………………………..3600kg
maximum torque …………………………………………………………………..56000kg·m
flywheel moment……………………………………………………………………1160kg·cm²
rotation frequency, max………………………………………………………..375rpm.
In metallurgy, on inclined conveyors, to prevent the spontaneous movement of the belt with a load downward, in case of a power outage or emergency disruption of the kinematic connection, reverse stops are provided in the drives. During normal operation of the conveyor drive, the electromagnet is turned on and the ratchet stop pawls are raised above the ratchet wheel. With the reverse rotation of the drum, the electromagnet is turned off, and the pawls are lowered onto the teeth of the ratchet wheel.
