The hoist unit comprises a generally “U” shaped base frame having spaced side members provided with multi-terrain wheel assemblies, a closed forward end having a hitch member for releasable attachment to a towing vehicle, a rearwardly open center section adapted to receive and straddle the load, a power cylinder, a boom operated by the power cylinder for lifting and securely holding the load in a transport position during movement of the hoist unit and for accurately depositing the load at the desired destination.

Abstract: In a counterweight attaching and detaching apparatus for a crane, the length of a suspension member is adjusted by an extendable member and links because the distance provided between the peak of a gantry and an upper surface of each of weights when the gantry is suspending the weight at a respective mounting position varies depending on the mounting position. In order to complement the adjustment of the length, different amounts of protrusion of rings from the upper surfaces of the weights are set so that the protrusion amount in the forefront weight is the largest and the protrusion amount in the rearmost weight is the smallest. This reduces the number of types of necessary links used in the suspension member to attach and detach the weights, and the number of operations of connecting and removing the links, and improves operation efficiency.

Abstract: A sway dampener is provided for reducing sway motion of a gantry crane spreader that is suspended from hanger chains. The sway dampener is configured to resist motion of the hanger chain relative to the spreader, thereby retarding sway. The dampener includes first and second portions that are movable relative to each other in a resistive fashion, for example a piston-cylinder structure. The first portion is mounted to the spreader and the second portion is mounted to the hanger chain at an attachment point located a vertical distance above a point at which the hanger chain is pivotally mounted to the spreader so that horizontal sway motion of the attachment point relative to the spreader displaces the first and second portions.

Abstract: A crane tower device includes a basket that supports a tower crane and sits within a bay formed by the vertical columns of a building under construction. The basket and the tower crane are supported by support stubs that are attached to the vertical columns. Because the lateral and vertical load is principally distributed vertically to the vertical columns rather than horizontally, no reinforcement of the horizontal beams, floors or any other portion of the building structure are needed, which results in substantial cost savings.
