The second generation Big Tow winches are the first choice for theater installations and touring productions that need to move scenery or fly performers across the stage. The BT2 winches incorporate zero fleet technology, allowing the winch to be mounted easily in any position by ensuring the drum take-off point remains static. The BT2 winches conform to the BS7905-1:2001 standard and the European Machinery Directive due to safety features such as dual brakes and a crossed groove detector. The winches also offer optional safety features including load cells, a slack rope detector, and a secondary encoder. Optional winch control systems are available for applications to be incorporated into SIL 3 installations.
