A cable steering system directs steel cables, for lifting cabinet shelf. The cable steering system includes left and right devices each comprising a first transmission wheel for horizontally turning the cable, and a second transmission wheel for vertically turning the cable which extends out from the first transmission wheel; and the cable extending out from the second transmission wheel is located in the middle of a side edge of the cabinet body. With the steel cable steering devices of the lifting cabinet, each steel cable extends horizontally along the first transmission wheel, and then is directed vertically downwardly by the second transmission wheel, thereby the cable is connected to a middle part of a side edge of the lifting shelf, so that the lifting shelf bears a balanced force.

A counterweighted theatrical rigging system for movably supporting theatrical equipment above a stage floor. The rigging system includes a batten on which the theatrical equipment is configured to be supported. A counterweight arbor of the rigging system is configured to balance and offset the weight of the loaded batten. The counterweighted theatrical rigging system is convertible between a first configuration in which the batten and the counterweight arbor are linked for corresponding movement in opposite vertical directions, and a second configuration that allows the batten to be lowered to the stage floor while the counterweight arbor remains in a lowered position for ballasting the counterweight arbor from the stage floor.
