  • Patent number: 9604823
    Abstract: An assembly for controlling a vertically extending member includes a device (22) having a stop member (34) and a speed control member (36) for controlling movement of the vertically extending member such as an elevator load bearing member (32) during a roping procedure. In a disclosed example, the stop member (34) is biased into a stop position where the vertically extending member (32) is locked between a brake pad (60) and a guiding member (54) so that the vertically extending member (32) cannot move relative to the device (22). An example input member for moving the stop member (34) out of the stop position comprises a foot pedal (70) that can be manipulated to control a position of the stop member (34). Absent manual manipulation of the input member, the stop member (34) prevents movement of the vertically extending member (32).

  • Publication number: 20130306406
    Abstract: A lift includes a mast and a brake module. The mast is for disposing on a working surface and has at least one track. The brake module is connected to a lift module mounted on the mast and includes at least one friction member and at least one forcing member. The friction member has a pressing portion and an axle oppositely arranged. The pressing portion is substantially shaped to engage the track. The forcing member is rotatably disposed on the axle for pivoting axially between a first position and a second position. At the first position, the pressing portion can be moved along the track and stopped by the lift module. At the second position, the forcing member displaces the friction member to force the pressing portion tightly against the track. Thus, the brake module is held in position relative to the mast.

  • Patent number: 8584801
    Abstract: The invention is a hoisting and placement system that also serves as a mobile land based complete crane system that is useful on a building under construction. The crane system can be installed on any floor that has been completed. As the height of the building of the building rises with upper floors that have been completed, the completed crane system can follow the upward work progress by virtue of its own construction. This construction includes a vertical tower mast system that can be attached to completed floors. The crane system can climb up or down on this tower mast system by using various mechanisms to engage one of the masts which form the tower mast system. The tower mast system can support various lengths loading platforms that can move into or out of a building floor.

  • Publication number: 20130240294
    Abstract: A step stool includes an inner frame, an outer frame, an actuator, and a coupler. The inner frame includes two inner pillars, and the outer frame includes two outer pillars attached to a platform near opposite ends of the platform and configured to receive the two inner pillars. The actuator is coupled to one of the two inner pillars and one of the two outer pillars, and is operable to raise the outer frame relative to the inner frame. The coupler couples the two outer pillars to each other to evenly lift the opposite ends of the platform when the actuator raises the outer frame.

  • Patent number: 8534420
    Abstract: An apparatus is disclosed for safely lowering a user from a structure. The apparatus includes a ring structure configured to coaxially surround a pole structure including a spiraling inclined surface, wherein the ring structure includes a circular track; a brake mechanism having a first portion configured to travel along the spiraling inclined surface and a second portion configured to travel along the circular track when the apparatus is descending; and a user support assembly for supporting a user when the apparatus is descending, wherein the user support assembly is securely attached to the ring structure. The user support assembly includes a seat or net securely coupled to a vertically-adjustable member which is, in turn, coupled to a fixed member by way of a ratchet interface. The apparatus also includes a torque limiting mechanism configured to prevent or reduce axial rotation of the ring structure when the apparatus is descending.

  • Publication number: 20130228397
    Abstract: Provided herein are wind turbine tower assembly and maintenance systems and schemes. In particular, wind tower maintenance platforms are provided in order to allow service personnel to perform assembly and maintenance tasks on wind turbine towers. Some platforms disclosed herein adjust to the outer diameter of the tower, which varies tuned to the general conical shape of the tower. Other platforms provide a platform shape that allows the platform to encircle both the tower and wholly or partially encircle the turbine blade to allow personnel easy access to the blade. Other variations disclosed herein provide powerful climbing mechanisms to allow the turbine service platform to externally climb the tower carrying service personnel, parts, or even turbine blades. Gripping or braking mechanisms are provided to secure the service platform to the tower. A system is provided for lowering or raising turbine blades to and from the hub without requiring a crane.
