<p>Adjustable Slider Bearing Assembly The invention provides several embodiments of support assemblies suitable for use in a lift mast. Each support assembly has two slider bearings for symetrically loading the main loading surface and the inboard and outboard flange edge of the corresponding I-beams used in an upright assembly incorporated in the lift mast. The support assemblies include positioning screws for adjusting the slider bearings against the flange edges. The need for shims is thereby avoided. These positioning screws permit the slider bearings to pivot so as to ensure they remain in full face contact with the corresponding flange edge. The slider bearings each accept two, mutually perpendicular loadings simplifying the construction of these support assemblies.</p> |
