Abstract

A device for connecting to, lifting at a first location load support surface, moving, inverting and releasing at a second load support surface individual heavy loads. The device includes a support frame for carrying heavy loads. The frame carries a mechanism for selective and controlled connection to and selective and controlled detachment from individual heavy loads, such as concrete molds with or without concrete in the molds. A lifting mechanism for providing selective and controlled vertical upward and downward movement to the connection mechanism and to any individual heavy load carried by the connection mechanism is associated with the connection mechanism. A mechanism for providing selective and controlled rotational movement of at least about 180.degree. to the connection mechanism and to any individual heavy load carried by the connection mechanism is also associated with the connection mechanism. Finally, the device includes a mechanism for moving the support frame and any individual heavy load carried by the support frame in a selective and controlled direction. The resulting device is capable of selective and controlled connection and attachment to individual heavy loads located at a first location, the lifting of such loads vertically upward, the moving of such loads, the rotation of such loads by at least about 180.degree., the lowering of such loads vertically downward at a second location, and detaching of the connection mechanism from the individual heavy loads to deposit them at that second location.
