Abstract
The operator's station of a lift truck is optionally elevatable with the carriage and the electric control interconnection between the operator's station, and the truck main frame includes a novel reel mechanism for the multiple lead electric conduit which does not use slip rings. The reel mechanism includes two drums which rotate together on a stationary shaft secured to the main frame. One drum is for coiling a flexible multi-lead round conduit which has its free end connected to the electric control console at the operator's station. The other drum contains a multiple lead flexible ribbon having its outer end connected to the inner end of the round conduit. The ribbon is coiled about the stationary shaft with its radially inner end passing through a hollowed portion of the stationary shaft and thence to a point of connection to a terminal block on the main frame. As the operator's station is raised with the carriage the round conduit is reeled out from the primary drum thereby rotating it against the bias of a windup spring. As the round conduit is reeled out from the primary drum the secondary drum is coiling the loosely wound ribbon about the shaft thus increasing the number o…
