摘要： A braking mechanism for a hoist incorporating two winding drums with brakes biased to move to the brakes applied state and fluid pressure means controllable by valves to operate in opposition to the biasing means has a bridge pipe containing a stop valve interconnecting the individual fluid supply lines leading from the control valves to the fluid pressure means. It also has isolator stop valve means arranged to control the flow of operating fluid to the control valves. The stop valve in the bridge pipe and the isolator stop valve may be arranged for remote control and may be biased so that the stop valve in the bridge pipe tends to open and the isolator stop valve tends to close.

摘要： A mine winder has two cable drums and a braking mechanism for each. Each braking mechanism includes means operable to sense if the cable is moving and in which direction and the length of cable paid out and to issue a control signal containing this information. Brake control means is operable on receipt of the control signal to operate braking means and apply to the drum a braking effort based on the information in the control signal. A cable movement detector sensitive to the speed of movement of the cable may be provided to be operative to send a corresponding control signal to the brake control means. The braking means may be air-pressure operated, the brake control means adjusting the air pressure according to the control signal received.
