  • Publication number: 20110260127
    Abstract: The inventive concept involves a tree mounted hoist that can be attached to a tree at any desired height. The tree hoist consists of a support platform that has an electric motor therein. The other direction of the support platform has a plate that has serrated teeth thereon that will dig into a tree when forced thereat. The support platform has an upstanding frame thereon and the ends of the upstanding frame each have a locking sleeve thereon. The locking sleeve each receive the end of a flexible cable that surrounds the tree and when tightened around the tree stabilizes the support platform on the tree. The support platform has a forward extension thereon that has a cable pulley at its forward ends over which a hoist cable is trained which hoist cable connects to a winch which is operated by the motor. The electric motor is a 12 Volt vehicle starter motor which can be operated by a remote switch.

  • Publication number: 20110052326
    Abstract: An embodiment of a self-releasing cable lift system may include a latch coupled to a winch and operable to lift an object, such as a gangway, into a secured position before self-releasing after the object is locked into place. Such a latch may be biased to an open position when setting free, but biased to a closed position when acted upon by an outside surface. Thus, the latch includes a first biasing surface that is operable to bias the latch to the closed position when the latch is moved into contact with a latch receptacle in a first direction. Further, the latch includes a second biasing surface that is operable the bias the latch to a closed position when it is moved into contact with a sleeve, in a second direction. In this manner, the latch may engage a gangway, when lowered, but then self-release when the gangway has been raised.

  • Publication number: 20110042634
    Abstract: A rigging system for raising and lowering a load includes at least one tether suspended between first and second spaced apart connection points. A hoist apparatus is selectively movable along the at least one tether and is coupled to the load so that movement of the hoist apparatus causes the raising and lowering of the load. The hoist apparatus can include drive pulleys and guide pulleys. A connection apparatus for connecting a tether to a fixed surface includes a base plate, a spring mechanism, at least at least one end plate, and a bushing member coupling the second end of the spring mechanism to the end plate. Tension on the tether causes the spring mechanism to compress and reduce distance between the end and base plates.
