The parking brake includes a brake housing, a brake shaft supported rotatably around the axis of the brake housing, a brake gear attached to the brake shaft and meshed with a transmission gear, first brake plates attached to the brake shaft, second brake plates attached to the brake housing and alternately arranged with the first brake plates, and a brake piston arranged so as to move toward and away from the plates and in the brake housing for bringing the plates into pressure contact with each other.

A brake disc release device, a turning device, and an elevator rescue package and method. The brake disc release device comprises: an actuating mechanism; a gear connected to a first end of the actuating mechanism; a first slider capable of sliding along a first guide piece and comprising a rack portion for engagement with the gear and a first wedge portion; a second slider capable of sliding along a second guide piece and comprising a second wedge portion for engagement with the first wedge portion of the first slider; and a pulling cable having a first end connected to the second slider and a second end connected to the brake disc.

A lifting-device brake system includes at least one brake assembly configured to be activated by a spring force. The at least one brake assembly is configured to achieve a braking effect. At least one piston/cylinder assembly is configured to be actuated by a hydraulic or pneumatic pressure via which the braking effect achieved by the at least one brake assembly can be reduced by at least partially overcoming the spring force. A hydraulic or pneumatic assembly is configured to provide the hydraulic or pneumatic pressure to actuate the at least one piston/cylinder assembly. The hydraulic or pneumatic assembly comprises an apparatus configured to maintain the hydraulic or pneumatic pressure applied to the at least one piston/cylinder assembly.

A no-back device for resisting feedback torque from an actuator. The no-back device comprises: a flange arranged to receive torque via a shaft; a ratchet assembly comprising a ratchet wheel arranged parallel to the flange; and a braking assembly comprising a resistance wheel, which is sandwiched between the flange and the ratchet wheel, and a braking device, which acts on the resistance wheel to generate a resistive angular force reacting against torque exerted on the resistance wheel. The braking device comprises a follower arranged to roll, under bias from a spring in the braking device, on a cam surface extending around a circumferential perimeter of the resistance wheel. Radial displacement of the follower energizes the spring to generate resistive angular force.

To realize a mechanism that can support an article at a desired position in such a way as to be able to move the article, with a thin, simple configuration. A load support mechanism 1 includes a fixed support section 2, which includes a fixed cam 8; a movable support section 3, which receives a load and can move vertically; a horizontal cam groove 13, which is provided in the movable support section; a cam follower member 15, which can move horizontally along the cam groove; a first spring 4, which is mounted between the fixed support section and the movable support section to support a load; and a second spring 18, which pushes the cam follower member horizontally and presses the cam follower member against a fixed cam surface 9 of the fixed cam. A reaction force of the fixed cam against the cam follower contains a vertical component depending on a height position of the movable support section, and the vertical component assists or reduces the spring's force to push up the load. A cam shape of the fixed cam surface is provided in such a way that the load acting around the cam follower, the spring forces of the first and second springs, and the reaction force applied from the fixed cam are balanced against each other.

A rotating table is maintained in a stationary state by generating a clamping torque while ensuring a long enough lifetime of a plate spring. Provided is a rotating table device including: base members; a rotating member that is supported by the base members so as to be rotatable about an axis; a brake disk that is secured to the rotating member; and a clamping mechanism that clamps the brake disk, wherein the clamping mechanism is provided with a piston that is attached so as to be movable between a clamped position and an unclamped position in a direction along the axis with respect to the base members, a plate spring that is secured to the piston and the base members and that biases the piston toward the clamped position, and a coil spring that is disposed between the piston and the base members, and that constantly biases the piston toward the clamped position.

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.

A medical device assembly including a support member, a first arm rotatably connected to the support member at a first rotary axis, a second arm rotatably connected to the first arm at a second rotary axis, and a medical unit connected to an end of the second arm opposite the first arm. The first arm is prevented from rotating about the first rotary axis when the first arm and the second arm are substantially aligned. The first arm and/or the second arm can also be prevented from rotating to prevent the medical device assembly from abutting against an obstacle.
