A transfer assembly for a hoist unit for a patient includes a motor base, a first frame secured to the motor base for rotation about a pitch axis. The first frame includes one or more first suspension wheels rotatably affixed thereto for rotation about a laterally extending axis. The transfer assembly also includes a second frame secured to the first frame for rotation about a yaw axis. The second frame includes one or more second suspension wheels each of which is rotatably affixed thereto for rotation about a laterally extending axis. The transfer assembly also includes a drive wheel assembly rotatably mounted on the motor base for rotation about a laterally extending drive wheel axis. The transfer assembly also includes a motor assembly secured to the motor base and operatively connected to the drive wheel assembly such that operation of the motor rotates the drive wheel assembly.

An overhead lift unit includes a carriage, a first wheel assembly, a second wheel assembly, and an actuator. The first wheel assembly includes a first wheel coupled to the carriage through a first support arm. The second wheel assembly includes a second wheel coupled to the carriage through a second support arm. The actuator is coupled to the second wheel assembly and is configured to shift the second wheel assembly in a lateral direction relative to the first wheel assembly between an expanded position and a retracted position. Lift systems including the overhead lift unit and methods of transporting the overhead lift unit to and from an overhead rail are also described.

A low-construction trolley for a wire rope hoist is arranged to travel along a lower flange of a horizontal rail, on both longitudinal edges thereof. The trolley includes a trolley frame; bearing wheels that are attached to the trolley frame and arranged to travel on an upper surface of the lower flange of the rail; a hoisting mechanism including a rope drum for a hoisting rope, a hoisting member in cooperation with the hoisting rope for hoisting a load, a hoisting motor for driving the rope drum, and a gear to interconnect the hoisting motor and the rope drum; whereby the rope drum is supported to one side of the trolley frame and the hoisting member is arranged to travel under the rail in a vertical plane (A) passing substantially through the middle of the beam. For balancing the trolley without using a counterweight, the hoisting motor is placed under the rail and at least partly on a different side than the rope drum in relation to a vertical plane (B) passing through contact lines of the bearing wheels that touch the lower flange of the rail on the rope drum side.

A plate assembly for mounting an electrical enclosure in a position vertically aligned atop an overhead rail used to support a traveling hoist which traverses back and forth along the rails on a trolley. The plate assembly includes a plate which is shaped like an inverted U by a central opening extending up from the bottom with mounting portions projecting normal to the plate which are configured to be attached to the enclosure when installed in the opening at the top and to respective rail pieces clamped against respective sides of the opening.

A trolley of a crane is arranged to move along a main support structure of the crane. The trolley includes a support frame structure; bearing wheels fastened to the support frame structure and by means of which the trolley is arranged to move along the main support structure; a hoisting mechanism that has a rope drum for a hoisting rope; a rope pulley arrangement through which the hoisting rope may be guided from the rope drum to a fixed fastening point on the trolley; and a hoisting member in cooperation with the hoisting rope for hoisting a load. The rope drum is supported to the support frame structure of the trolley so that the axle of the rope drum is parallel to the main support structure. The rope pulley arrangement is located, in the axial direction of the rope drum, at least partly outside one rope drum end which is on the side of said fastening point. The support frame structure is divided into two separate frame parts, whereby the first frame part supports the rope pulley arrangement and the rope drum end on the side thereof, and whereby the second frame part supports the opposite end of the rope drum.
