A brake cylinder includes a locking device for mechanical brake force locking, in particular for rail vehicles, and a service brake piston which can be axially moved inside a housing, which can be moved by applying a pressure medium thereto, and which is coupled to a piston tube, said piston tube being provided with a non-self-locking thread which is engaged with a threaded nut which is rotatably mounted in the housing, and the locking device cooperating with toothing of the threaded nut. The brake cylinder is designed such that the locking device comprises one or more pawl(s), a control piston, an emergency release tappet, and a locking element of the emergency release tappet.

A parking lock-releasing device for a vehicle, which is capable of improving workability in manually releasing a parking lock while ensuring sealing performance of an outer casing, and easily holding the locking released state. The locking release operation section includes a base having a hollow cylindrical guide portion and concentrically continuous with a front end of the outer casing, with a female screw formed on an inner peripheral surface thereof, and an operating section body which is screwed via a male screw formed on an outer peripheral surface thereof into the female screw of the guide portion, closes the guide portion, holds a front end of the inner cable, and when releasing the locking, is rotatingly operated in a predetermined direction relative to the base, to thereby cause the inner cable to slide to be pulled in the direction away from the parking mechanism.

A hydraulic power take-off is provided for use with industrial drives that deliver power to industrial equipment. The hydraulic power take-off has a brake disconnect system that can manually release a brake assembly to allow low-effort rotating of the industrial equipment components to facilitate servicing.

Provided is a non-excitation operable electromagnetic brake that includes a manually operable rotary cam for switching over a rotor to a brake releasing state, but that allows easy recognition of switchover to the brake released state via an operation reaction force and that also allows reliable keeping of the rotary cam under its acting state. Even when an electromagnet is under a non-excited state, when a rotary cam is rotatably operated to an acting position, an acting portion of the rotary cam slidably operates a rotor via a releasing plate to a brake releasing state against springs. The acting portion of the rotary cam is formed linear along a tangent at a center of the acting portion with respect to a rotary cam rotational direction.

A traction assembly for terrestrial traction machines, which includes at least one gearmotor adapted to be associated with a track or wheel of the terrestrial traction machine, and a parking brake of an electromagnetic type which is associated with the gearmotor, and wherein the parking brake is of a multi-dry-disk type and is interposed between the driving component of the gearmotor and a speed limiter of the gearmotor.

A turning device includes a hand disc coupled to an input shaft; a reduction gear set accommodated in a housing and connected to the input shaft and an output shaft; and a shaft connector for connecting the output shaft and a motor spindle.

A lift vehicle comprises a base having a plurality of wheels, a battery arranged within the base, a drive motor powered by the battery and configured to drive at least one of the plurality of wheels and propel the base, a retractable lift including a first end coupled to the base and being movable between an extended position and a retracted position, a work platform supported by a second end of the retractable lift, and a linear actuator having a lift motor with a rotor. The lift motor is powered by the battery, and the linear actuator is coupled to the retractable lift so that rotation of the rotor moves the retractable lift between the extended position and the retracted position. The lift vehicle further includes an electromagnetic brake coupled to a first side of the lift motor.

A scissor lift includes a base, a platform, a lift assembly, and a linear actuator coupled to the lift assembly. The lift assembly includes a first support member pivotally coupled to a second support member and a third support member pivotally coupled to a fourth support member. The linear actuator includes a housing, a screw coupled to the housing, an extending member slidably coupled to the housing, and an electric motor coupled to the housing and configured to drive the screw to move the extending member relative to the housing. The housing includes a first mount coupled to the first support member and configured to rotate relative to the first support member about a first lateral axis. The extending member includes a second mount coupled to the third support member and configured to rotate relative to the third support member about a second lateral axis.

An electric linear actuator for a lift assembly of a scissor lift includes a housing having a first end defining an aperture and a second end opposite the first end, an extending member received within the aperture and slidably coupled to the housing, a screw coupled to the housing, and an electric motor coupled to the housing and configured to drive rotation of the screw to control movement of the extending member along an axis of extension. The housing includes a mount configured to pivotally couple the housing to the lift assembly of the scissor lift. The mount is offset from the second end of the housing along the axis of extension such that the mount is positioned between the first end and the second end of the housing.
