A lifting cabinet includes a transmission assembly and a power unit for raising and lowering a shelf. The transmission assembly comprises a first transmission unit, comprising a screw rod which is connected with a driving device and a sliding piece which is connected with the lifting shelf, and the sliding piece is coupled to the screw rod. The screw rod rotates under the action of the driving device and drives the sliding piece to move back and forth along the axis of the screw rod; and then the sliding piece drives the lifting shelf to move up and down. For the lifting cabinet and the power unit thereof, the transmission assembly converts a rotary motion outputted from the driving device into a linear motion through the cooperation between the screw rod and the sliding piece, and a greater axial force is thereby outputted. Thus, a relatively small motor with a lower output torque can be used in the lifting cabinet to drive a lifting shelf of the same weight when compared to the conventional lifting cabinet, and the problem of large motor in conventional lifting cabinet taking up too much space is thereby solved.

An innovative drive system for a hoist assembly is disclosed. The hoist drive system is designed to lift at fixed speeds or at variable speeds. The hoist drive system operates with little noise and provides for minimal maintenance during the life of the hoist that requires no lubrication, has superior environmental resistance, and a compact design.

A hoist brake system is disclosed. The brake system incorporates an electro-mechanical device that acts as a fail-safe stopping mechanism for a hoist and has a default engaged. This allows the brake system to quickly and safely stop a device when power is lost, an emergency signal is provided or any other fault condition and be completely self-contained within the hoist itself.

The invention relates to a drive device (1) for the spool (6) of a winch. The drive device (1) comprises a drive motor (2) having a drive shaft (5), a transmission (3) and an output shaft (4) that drives a spool (6). The transmission has a first drive connection (10) between the drive shaft (5) of the drive motor (2) and the output shaft (4) to the spool (6). The first drive connection (10) drives the output shaft (4) over a first rotational speed range (DB1) in a first gear. According to the invention, a second drive connection (30) is provided between the drive motor (2) and the output shaft (4), wherein the second drive connection (30) drives the output shaft (4) over a second rotational speed range (DB2) in a second gear. The second drive connection (30) is designed to be separate from the first drive connection (10) as a parallel drive path, and is driven by the drive motor (2) together with the first drive connection (10). If the output shaft (4) is driven by the second drive connection (30), the power flow of the first drive connection (10) from the drive shaft (5) to the output shaft (4) is interrupted.

A lifting cabinet has left and right lifting mechanisms each comprising a steel cable; a power mechanism which is connected with a first end of the steel cable; an internal guide rail which is connected with a second end of the steel cable; and an external guide rail which is fixed on a frame of the lifting cabinet and is configured with an accommodation space therein. The internal guide rail is located within the accommodation space. The lifting cabinet solves the problem of exposure of the steel cable.

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 lifting cabinet, comprises a cabinet body, wherein the cabinet body comprises a side plate in which at least two wire through-holes are configured, a trunking which is configured in the side plate for communicating with the two wire through-holes, and wires which are placed in the trunking and are respectively connected to electric parts in different spaces within the cabinet body through the two wire through-holes. The cabinet solves the problem of messy and unsightly appearance caused by unreasonable wire arrangement.
