Personnel Lift With Adjustable Shim Wear Blocks

US Patent:
6095286, Aug 1, 2000
Filed:
Oct 15, 1998
Appl. No.:
9/173537
Inventors:
Steven D. Citron - Redmond WA
Ronald A. Teter - Kirkland WA
John Busuttil - Redmond WA
Matthew G. Kraemer - Redmond WA
Ronald L. Williams - Woodinville WA
Assignee:
Genie Industries, Inc. - Redmond WA
International Classification:
E04G 118
US Classification:
182148
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.
