Abstract
A standard hook-type carriage assembly designed for lift truck use in the handling of palletized cargo is converted for use in the handling of concrete blocks by hooking block-handling forks on the carriage plate and positioning such forks on the carriage plate with predetermined lateral spacings between the forks by a removable elongated spacer bar to which all of the forks are attached. Lost-motion connections are made between the forks and the spacer bar and limited lengthwise movement of the spacer bar relative to the carriage plate is permitted so that the forks can float, relative to each other and in unison, laterally along the carriage plate. The forks can also move independently of each other through a limited vertical distance relative to the carriage plate.
