Abstract
Yieldably suspended attachments for lifting trailers or containers are difficult to accurately position. Therefore, load pick-up and deposit is inefficient and inaccurate. A load lifting attachment having an elevationally movable connecting frame, a load engaging frame having first and second end portions, and first and second link assemblies yieldably connecting the load engaging frame to the connecting frame first end portion is provided. A connecting arrangement connects the load engaging frame second end portion to the connecting frame, maintains the load engaging frame for free elevational movement relative to the connecting frame, and controllably moves the load engaging frame second end portion between elevationally spaced apart locations relative to the connecting frame. Therefore, the aforementioned problems related to the positioning of the load lifting attachment are alleviated. The load lifting attachment is particularly suited for use on a material handling vehicle having a lift mast.
