PANTECHNICON. A pantechnicon is a train of sleds carrying the services to the longwall face. It is generally located on the maingate road, along the belt conveyor. It is usually pulled or dragged along the roadway in concert with the advance of the face. The dragging of the system is achieved either by a winch, or by a hydraulic ram.
