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.

The present disclosure relates to a fork-lift truck, comprising, a housing, a mast, an actuating device, a framework extension assembly, a control unit, a pair of support legs. The fork-lift truck is provided with a sensor device that is arranged to detect a predetermined rotary position of at least one rotary axis of the framework extension assembly. The control unit is arranged to determine and set a maximal speed and/or a maximal acceleration, and/or a maximal deceleration, and/or a maximal lift height, and/or a maximal load weight, of the fork-lift truck based on the detected predetermined rotary position of the said at least one rotary axis.

A rotating shaft lifting jig is inserted between a rotating shaft of a rotary machine and a bearing stand surrounding the outer periphery of at least a lower part of the rotating shaft. The jig for lifting the rotating shaft includes: a pedestal which is supported on an inner peripheral surface of the bearing stand; and a jack part which is disposed between the pedestal and the outer peripheral surface of the rotating shaft and extends/contracts in the radial direction. The radial dimension of the pedestal is smaller than a radial clearance between the rotating shaft and the bearing stand. A rotor receiver having a cylindrical surface conforming to the outer peripheral surface of the rotating shaft is provided between the jack part and the rotating shaft. The rotor receiver is provided with a plurality of support members in directions different from the direction of the jack part.

A scissor boom system including a scissor boom assembly having a telescopic boom section including a base-boom, a middle-boom, and a top-boom, a scissor links assembly, a chassis, and a power hoist. The chassis supports the power hoist, the power moves the telescopic boom section and the scissor links assembly between raised and lowered conditions when manipulated. The scissor boom assembly provides a stable work platform for workers. The telescopic boom section provides for horizontal-movement of a work platform, and the scissor links assembly is thus able to provide vertical-movement of the work platform, as desired.

A lift device includes a chassis, a lift boom, a sensor, and a controller. The chassis includes a frame, an axle pivotally coupled to the frame, and an actuator positioned to move the axle. The lift boom is rotatably coupled to the chassis and operable within a work envelope, and the sensor is positioned to monitor an orientation of the lift boom. The controller is configured to engage the actuator based on the orientation of the lift boom. Engagement of the actuator moves the axle to adjust the work envelope of the lift boom.

An anchoring assembly is provided for the aerial lift platform of an aerial lift vehicle. The anchor assembly extends through the walls of a bucket liner and a bucket platform, and provides a strong anchor disposed inside of the bucket liner for use in attaching an operator harness to prevent the operator from being ejected from the bucket platform. The anchor assembly also provides dielectric protection mandated by OSHA and ANSI standards.
