Abstract
A crane hoist apparatus and method of use for moving items within, into, out of, or adjacent to an interior of a containerized cargo enclosure causing minimal loss of interior enclosure volume from the crane. The crane includes a first frame with a plurality of beams each having a span, a width, and a depth, the first frame is supported by the enclosure, also a second frame having a beam with a span, a width, and a depth, that is slidably supported by the first frame in a transverse span orientation, with the second frame depth not extending below the first frame depth, the second frame moves in a direction parallel to the first frame span. A winch carriage is slidably supported by the second frame wherein the winch does not extend below the second frame depth, the winch moving in a direction parallel to the second frame span.
Claims14
A crane hoist apparatus for use in moving items within, into, out of, and adjacent to an interior of a containerized cargo enclosure with a minimal loss of interior enclosure volume from the crane, comprising:
- (a) a first frame having a plurality of beams that each include a lengthwise span, a width, and a depth, said first frame is supported by the containerized cargo enclosure;
- (b) a second frame having a beam with a lengthwise span, a width, and a depth, said second frame is slidably supported by said first frame in an approximately transverse span orientation such that said second beam depth does not extend below said first frame depth, said second frame is able to move in a direction parallel to said first frame span;
- and
- (c) a winch carriage that is slidably supported by said second frame beam such that said winch carriage does not extend beyond said second frame beam depth, said winch carriage being able to move in a direction parallel to said second frame beam span, wherein said second frame beam is a single “L” beam and further including a cable attached to said winch carriage for lifting an item.
A crane hoist apparatus for use in moving items within, into, out of, and adjacent to an interior of a containerized cargo enclosure with a minimal loss of interior enclosure volume from the crane, comprising:
- (a) a first frame having a plurality of beams that are each constructed of a “L” beam that includes a horizontal extension, a vertical extension and a lengthwise span, said first frame is supported by the containerized cargo enclosure;
- (b) a second frame having a beam that is constructed of a “L” beam that includes a horizontal extension, a vertical extension and a lengthwise span, said second frame is slidably supported by said first frame in an approximately transverse span orientation such that said second frame does not extend below said beam vertical extension of said first frame, said second frame is able to move in a direction parallel to said first frame span;
- and
- (c) a winch carriage that is slidably supported by said second frame “L” beam such that said winch carriage does not extend beyond said second frame “L” beam vertical extension, said winch carriage being able to move in a direction parallel to said second frame “L” beam span wherein said second frame “L” beam is a single beam and said winch carriage has a cable attached for lifting an item.
