Patent

CA 2297494

An inclined elevator for excavating an open cut mine in scopes has a traveling platform and counterweight coupled by cables whose upper and lower passes extend over upper and lower cable pulleys to the drum of a conveyor or drive machine. The cables can pass around a rerouting pulley which can be shifted on the foundation for the inclined elevator to compensate for increased depth of the excavation. The traveling platform which carries the car or truck for the mined material can have pins engaging in a bottom which is removable from the platform and can be locked in upper and lower positions relative to the foundation by pawls engaging in notches or recesses of the bottom.
