Abstract: A jacking assembly for a rotor of a turbine includes an arc-shaped saddle which extends around and supports a lower portion of a rotor. A lifting beam extends over the rotor transversely to an axial direction of the rotor. The lifting beam is axially aligned with the arc-shaped saddle. Two connectors are disposed on respective lateral sides of the rotor, each connector extending between and being coupled to the lifting beam and the arc-shaped saddle such that the saddle is configured to lift the rotor vertically when the lifting beam is displaced vertically.

Abstract: A system for enabling servicing of a rotor of a wind turbine is provided. A rotor servicing fixture attaches to a first and second rotor blade, and contacts a wind turbine tower. A clamp assembly is connected to the rotor servicing fixture, and clamps onto a third rotor blade. The clamp assembly lowers the third rotor blade from a hub and raises it back to the hub. A lifting assembly is connected to the rotor servicing fixture and the clamp assembly, and is configured for raising and lowering the third rotor blade via the clamp assembly. A slide assembly is connected to the rotor servicing fixture, and is configured to support the rotor part and to slidably move the rotor part away from or towards the wind turbine. The system enables the rotor part to be removed or replaced without requiring the rotor to be removed from the wind turbine.

Abstract: Jack units attach skates to an object to be moved. Each jack unit has a tongue that slidably engages a coupling slot affixed to the object, and can be operated to raise or lower the tongue; when raised, the object is supported on the skates and can be rolled to a new location. A crane can attach to lift eyes on the jack units to allow the system to be lifted with the skates attached to the object, avoiding the risk to operators of positioning the skates under the object while it is suspended. Rotation-limiting structures can be selectively employed to block rotation of the trailing skates to facilitate steering when rolling the object supported by the system. The coupling slots can be provided in coupling elements which can attach directly to the object or which can be employed to form a freestanding frame to which the object is secured.

Abstract: An apparatus for raising and lowering a payload, particularly a chair and its user to provide assistance with the sit-to-stand task. The apparatus comprises a base, a platform, linkages attached between base and platform to allow only vertical motion therebetween, an inflatable bag also situated between base and platform, and a source of pressurized fluid such as compressed air, whereby the bag is inflated and deflated to raise and lower the platform. The user may use an existing, favorite chair, including a reclining chair, which is placed upon the platform without modification. In a low position, the platform is quite close to the floor, providing comfort during sitting. In a high position, the platform is greatly elevated, to provide a full measure of sit-to-stand assistance. The apparatus is compact, doesn't interfere with reclining or rocking while sitting, and is easily deployable, movable, and storable.

Abstract: A collapsible hoisting device for use in the construction of large metal containers and to a removable accessory applicable thereto. It facilitates construction procedures by reducing project times and costs. The collapsible device includes a column (2) along which respective upper bodies (6) and lower bodies (7) that have been inserted into said column (2) move. The bodies (6, 7) are linked by an extendable means (8). The upper bodies (6) and lower bodies (7) have a corresponding mechanism to lock or attach (9) to the column (2), The column (2) is mounted so that it pivots with respect to a base (1) and the upper body (6) has a housing (609) suitable for the insertion of a removable, fingernail-shaped accessory (12).

Abstract: Implementations described herein provide a lift pin actuator. The lift pin actuator has a housing. The housing has an interior volume. A track is disposed in the interior volume and coupled to the housing. A center shaft is at least partially disposed in the interior volume of the housing. A guide is movably coupled to the track. At least one internal bellows is disposed in the interior volume, the internal bellows form a seal between the center shaft and the housing. An elastic member is disposed in the interior volume and configured to apply a force that retracts the center shaft into the housing. An inlet port is configured to introduce fluid into the interior volume between the internal bellows and the housing. The fluid generates a force opposing the elastic member to extend the center shaft relative to the housing.
