摘要： This method for protecting a lifting member against an overload, the lifting member comprising a lifting drum over which a cable is wound at the end of which a load is fixed, said lifting drum being mechanically connected to an electric motor capable of ensuring its rotation, the mechanical connection comprising a clutch or equivalent device, comprises at least two distinct operating thresholds:
a first threshold, the exceeding of which generates the freewheel operation of the lifting drum with respect to the kinematic chain coming from the electric motor;
a second threshold, of value greater than that corresponding to the nominal load of the lifting member, but of value less than that of the first threshold, generating the braking of the rotation of the lifting drum, and an attempt to progressively stop said rotation of the drum.-

摘要： The invention relates to a brake assembly (1) for securing a conveyor device, in particular a crane system (100), comprising a first brake device (7) which acts on a first drive element (3), a second brake device (8) which acts on a second drive element (5), a transmission device (4), in particular a gearbox, acting between the first and second drive element, a load sensor (13, 13′) which detects a load signal and passes same on to a controller (9), and the controller (9) is designed in such a way that, based on a load signal that exceeds an overload threshold, it initiates an emergency brake status and actuates the first and the second brake device (7, 8) in such a way that they act on the first and second drive element (3, 5) simultaneously within a first brake acting time, wherein one of the first and second brake devices is designed such that it acts on the first and/or the second drive element within a second brake acting time in a normal brake status, and the first brake acting time is shorter than the second brake acting time.

摘要： Disclosed are a winch, a rope guide, and a transmission device having a clutch function. The winch includes a base seat, a reel, a rope guide, a transmission assembly, and a motor. The reel is rotatably provided to the base seat. The rope guide is provided to the base seat. The transmission assembly is connected with the rope guide. The motor is connected with the reel to drive the reel to rotate, and the motor drives the rope guide through the transmission assembly. In the winch according to embodiments of the present disclosure, the rope guide is an active rope guide, bringing about a good rope guiding effect. Moreover, the reel and the rope guide are driven by the same motor, which reduces the number of components and parts, simplifies the structure and control, and lowers costs.

摘要： The invention relates to an abseiling device comprising a bidirectionally rotatable guiding arrangement (25) for guiding a pulling means (26); further comprising a braking mechanism (30) that is coupled to the guiding arrangement (25); a driving means (34; 35) can be connected to the guiding arrangement (25) so as to actuate the guiding arrangement (25). In order to create an abseiling device that prevents an individual from being injured or parts of the abseiling device from being damaged during rescue operations in particular of people, a mechanical torque limiter (33) decouples the driving means (34; 35) and the guiding arrangement (25) or the pulling means (26) when the torque exceeds a certain threshold value.

摘要： An apparatus includes a drum to draw in or let out a line, and a motor and transmission coupled to the drum to apply a torque thereto. In certain embodiments, the motor and transmission are substantially entirely contained within the drum. In the same or other embodiments, a bearing may provide support for both the transmission and the drum.

摘要： Disclosed is a torque limiter for a power winch, and a torque limit mechanism is installed for timely cut off the power transmission whenever the reverse torque generated by a carrying load exceeds a torque bearable by the power supply during a power transmission process for transmitting the power outputted from a power supply to a reduction mechanism through a long shaft, so as to prevent the power supply from being damaged by overload. The torque limit mechanism is formed by a torsion shaft, a friction plate, a brake pad, a disc-shaped elastic member, an adjustable positioning ring and a positioning screw ring.

摘要： 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.

摘要： A lifting hoist (10) having a drive train (14) containing a slip clutch arrangement (23) with a hysteresis clutch (26). The drive train (14) transfers torque, friction-free, in both forward and backward directions of movement between the motor (15) and a gearing (16). The hysteresis clutch (23) forms an unbranched torque transmission path between the motor (15) and the gearing (16). The hysteresis clutch (26) acts as a vibration damper, allows controlled emergency load lowering, and acts as a secure torque limiter in emergency malfunctions when lowering a load. It further can be used as a load indicator by reducing the load-lifting speed before the nominal load is reached or in the event of an overload.

摘要： A lifting hoist (10) having a powertrain (14) that includes a hysteresis clutch (23) for transmitting torque from a driving motor (15) to a transmission for moving a load pulling element (11). The hysteresis clutch (23) can be set to incur a slippage differing significantly from zero before a nominal load bearing capacity (FNom) of the hysteresis clutch is reached by the pulling element (11). Hence, when the lifting hoist operates within the range at or near the nominal load-bearing capacity (FNom), it is operable with continuous slip. The waste heat generated in the process is preferably transferred to the wall of the transmission housing via an oil bath, with the wall serving as a cooling surface. The lifting hoist can be built smaller and has improved operating properties.
