ABSTRACT:
A crane and lift apparatus for controlling the lifting and lowering of large cargo containers. A trolley assembly includes a hoist drum from which is suspended a system of cable or rope reevings connected to material securing assembly. The apparatus is effective to unload containers stacked one above another from one location to an alternate location. The system of cable reevings permits the raising and lowering of containers in planes defined by X, Y, and Z axes. The cables are deployed from the hoist drum on the trolley assembly to sheaves disposed at the four corners of the material securing assembly and then returned to anchor assemblies secured to an undercarriage of the trolley assembly. The sheaves are selectively angled and located in headblock assemblies positioned on the material securing assembly. A system of brakes controls movement of the cables through the sheaves. By selectively combining the angling of the sheaves with selective application of the sheave brakes, it is possible to resolve moment forces acting at each corner of a container so as to abosrb the constantly changing inertial movements that occur when the container is raised, lowered or moved horizontally. As a result, the apparatus is effective to dampen or retard the container from swaying, rolling, or pitching, from pendulous movement, and can thereby control the deployment of the container within precise vertical, horizontal, or skewed planes of orientation.
