NJ type contact backstop
The NJ type backstop is a contact anti-reverse device suitable for low speed shafts. Compared with the ordinary backstop (roller backstop ratchet, with brake), it has the advantages of light weight, compact structure, reliable force transmission, easy release, convenient installation and low installation accuracy requirements under the condition of transmitting the same backstop torque. Its comprehensive mechanical properties are significantly superior to other ordinary backcheck devices, is the preferred safety protection device for lifting transportation equipment, generally suitable for lifting belt conveyor, bucket elevator, scraper conveyor and other equipment with backcheck requirements.
