Abstract
A personnel lift (20) having adjustable side-to-side shim assemblies (38a-d) used in conjunction with a series of slide blocks (39, 40) in the mast of the personnel lift. The mast of the personnel lift includes a number of nested columns (24a-e) that extend to lift a person and an aerial work platform (22) to a desired height. The shim assemblies (38a-d) and slide blocks (39, 40) are used to maintain the nested columns (24a-e) in proper alignment, and the shim assemblies (38a-d) are adjustable to account for wear. The adjustable features of the shim assemblies (38a-d) are accessible when the columns are fully assembled, which allows the shim assemblies (38a-d) to be adjusted without requiring that the mast be disassembled.
