A winch (100, 200) includes a rope (105), an overwinding sensor (106) coupled to the rope (105) where the overwinding sensor (106) is moveable between a first position and a second position upon winding and/or unwinding of the rope (105). The overwinding sensor (106) includes a first electrically conducting member, a contact member (104) having a second electrically conducting member which is contactable by the first electrically conducting member when the overwinding sensor (106) is in the second position. The second electrically conducting member is not contactable by the first electrically conducting member when the overwinding sensor (106) is in the first position. The winch (100, 200) is configured to stop and/or prevent and/or hamper winding of the rope (105) upon establishment of an electrical contact between the first electrically conducting member and the second electrically conducting member when the overwinding sensor (106) is in the second position.

A system has a hoist system to lift a payload to a position adjacent to a ceiling of a room Image sensor systems collect visual data and payload depth data within the payload and ambient depth data within the room. A controller is connected to the hoist system and the image sensor systems. The controller is configured to control the motion of the hoist system. The motion of the hoist system is controlled in part by the ambient depth data from the room.

A hoist system that includes a hook; a cable connected to the hook; a motor configured to move the hook and the cable; and an overload protection device (OLPD) configured to limit loads imparted on one or more of the hook, the cable, and the motor. The hoist system further includes an overload protection device (OLPD) slip detection system configured to detect activation of the overload protection device (OLPD).

A spare tire winch mechanism which performs the steps of lowering the spare tire from its location and locating the flat tire on this location via a rope winding assembly. A worm gear and a threaded drum prevent the rope from winding onto the threaded drum in an overlapping and irregular manner which results in locking of the parts and the damage to the parts due to the application of extreme force during the winding. The spare tire performs free fall movement with its own weight as a result of the tire wrench being activated with a pulling force applied perpendicular to the floor axis and the worm gear disconnects from the drum body, in case one of the tires of the motor vehicle needs to be changed.

A system arrangement for the drive train of lifting mechanisms, such as crane lifting mechanisms, is disclosed. The system arrangement includes at least one drive motor (1, 1′), at least one cable drum (2, 2′) connected thereto, a reduction transmission (3) arranged between the drive motor (1, 1′) and the cable drum (2, 2′), an automatic overrun shutdown freewheel (6), and at least one safety brake (4, 4′). To optimize such a drive train, at least one active motor locking assembly (5, 5′) is utilized to hold the load when the drive motor (1, 1′) is decelerated electrically to a rotary speed of zero. The active motor locking assembly is utilized instead of at least one passive operating brake.

An elevator with a brake device may be configured to provide a variable brake force, from a minimum brake force up to a maximum brake force (Vmax). The brake device may include a first energy store that provides the maximum brake force and a second energy store that provides an adjustable counterforce. The adjustable counterforce may be directed in an opposed manner with respect to the maximum brake force provided from the first energy store. Further, the variable brake force may amount to a difference between the maximum brake force and the adjustable counterforce. In some cases, the first energy store may comprise a compression spring for providing the maximum brake force.
