Retractable Runaway Car Protection Device

Main Features:

This device is used in all single-track or double-track inclined tunnels with a slope of less than 30 degrees in coal mines, metal mines, non-metal mines, etc. It features fully automated control and monitoring, effectively preventing mine runaway car accidents.

This device consists of an operation box, electric control box, encoder, sensors, winch barrier, and energy absorber.

Functional Characteristics

The device adopts an advanced PLC control system and infrared sensors for speed measurement, improving the accuracy of the control system.

The audible and visual alarm system is interlocked with the winch control to ensure safe hoisting and transportation.

Uses pneumatic cylinders (hydraulic cylinders) or retractable winch drive to realize automated control of runaway prevention for inclined shaft hoisting transportation.

The PLC control system also has a detection function. By detecting the working status of position sensors, it controls the opening and closing of the barrier, avoiding false operations.

The device also features a normally closed barrier function and a smooth buffering function.
