A wide selection of monorail track switches are available for use in monorail systems. Switches are rated light-duty, medium- duty, or heavy duty. They are available in tongue or sliding operation models. Sliding switches offer smoother trolley operation than tongue switches because the track sections of sliding switches are curved and form an integral part of the track system curve. Some switches are limited to non-electrical operating systems. LOUDEN® monorail track switches are available with various operating mechanisms and controls. Depending upon the type of switch, they may be operated manually, by electric motor, or by air cylinder. Switch operation may be accomplished with pull ropes, pushbutton pendant stations, or remote control signals.
