Dual Rope Push/Pull Winch
Blast proof doors in mining ventilation
Two off Dual Rope winches were designed in conjunction with our client for the rapid opening and closing of Blast proof doors in a mining application. Each winch has two ropes, as one rope winds off the other winds on, each rope is connected through a series of sheaves to one end of each door, the winch is reversed to open/shut the doors. In addition the winches are fitted with a manual override crank handle in case of power failure the doors can still be operated.
All we need is a few details and we'll be in touch.
