Winch (1) comprising a drum (2), a cable (6) which can be wound around the drum (2), means (7) for fastening the load (20) to the cable (6), a motor (3) with a motor shaft (4), a control (17) for the motor (3) that drives the motor shaft (4) to rotate in two opposite directions, and mechanical transmission means (5) for transmitting the rotational movement of the motor shaft (4) to the drum (2), said means (5) being configured so as to allow, in the state in which the motor shaft (4) is driven to rotate in a first direction D1, the transmission of the rotational movement of the motor shaft (4) to the drum (2) in the direction of winding the cable (6) around the drum (2). In the state in which the motor shaft (4) is driven to rotate in the second direction D2, the mechanical movement transmission means (5) are configured so as to not allow the transmission of the rotational movement of the motor shaft (4) to the drum (2), and at least part of these mechanical means (5) is configured to form, in this second operating mode, a brake preventing the drum (2) from being driven to rotate.

A hoist comprising: an upper hook; a support shaft that includes a hook-side large-diameter portion inserted through an insertion hole of the hook at a center portion, end large-diameter portions at both ends, an intermediate portion between the hook-side large-diameter portion and the end large-diameter portion, and a strain deformation portion that is provided at the intermediate portion; a main frame that includes a pair of support holes and is suspended and supported by the upper hook via the support shaft with the end large-diameter portion on one side inserted in the one support hole and the end large-diameter portion on the other side inserted in the other support hole; and a load measurement means that is attached to the strain deformation portion and measures a shear load acting on the strain deformation portion, wherein at least a portion of the intermediate portion is inserted in the support hole.

The invention relates to a winch comprising a winding device, which is simply constructed and works very reliably, regardless of the position and orientation of the winch.

A shut-down buffer for a lifting device, in particular a chain hoist, includes two opposing end surfaces and at least two mutually spaced web elements extending between the end surfaces. The shut-down buffer is defined by the end surfaces, between which a through-opening for passage of a load-bearing element of the lifting device extends through the shut-down buffer.

A winch assembly includes a motor, a drum, and a gearbox. The drum extends from the motor to the gearbox. The winch assembly further includes a housing. The drum extends through the housing. The winch assembly further includes a fairlead. The fairlead is directly coupled to a face of the housing and provides structural support for the winch assembly.

A remote controlled lift assembly includes a pair of supports is each mountable to a respective outrigger of scaffolding. A winch unit is positionable on the supports when the supports are mounted on the scaffolding and the winch unit has a cable extending downwardly therefrom. The cable is lowered or lifted when the winch is actuated. A receiver is coupled to the winch unit and the receiver is in electrical communication with the winch unit. A remote control is provided that is carried by a user and the remote control is in wireless electrical communication with the receiver. In this way the user can remotely lift and lower the cable for lifting and lowering cargo.
