发明名称 Adjustable load lifting spreader frame
摘要 A spreader frame assembly for connecting onto large, elongate loads such as shipping containers and trailer vans for lifting and moving such loads. The assembly includes a trolley mounted on a straddle carrier with a spreader frame supported beneath the trolley. A positioning column descends from the trolley and makes a swivel connection at the middle of the spreader frame, and a pair of load lifting hydraulic cylinders mounted on the trolley connect at widely spaced points with the spreader frame. A rotate cylinder between the spreader frame and positioning column rotates the frame around a vertical axis, a tilt cylinder also between the spreader frame and column tilts the frame around a horizontal axis, and a translating cylinder between the trolley and column pivots the column to translate the spreader frame.
