And winch

Overview of retractable winch

Jf-150zd Sports car protective device The retraction winch is the supporting part of sports car protective device and is used as the opening and closing device to control the blocking of the car. When the harvester approached the bar, the winch made the car block raised; When the harvester passes through the bar, the winch makes the car block closed. If there is a sports car accident, the car bar block in the normally closed state, the car can be accurately and reliably stopped.

The winch is used as a protective device to intercept the runaway harvarder in the inclined shaft of single-track or double-track transportation in coal mine shaft or underground.

Functions and features of winch

Under the control of the control box of the sports car protective device, the winch can reliably lift and lower the bar, and automatically stop when lifting and lowering it into place. When the harvesters run at a normal speed, the harvesters run to the bar scheduled lifting point, the winch will block the bar to lift, let the harvesters through; When the harvesters run to the point where the guardrail is lowered, the winch will lower the guardrail and the guardrail will resume its normal closed state.

In case of overspeed or runaway sports car with broken rope, the winch will not work, and the bar will be in normal closed state to intercept the harvesters and play a role of safety protection.
