A slidable load lift apparatus is selectively completely retractable into the bed of a standard pickup truck. The load lift apparatus includes a base frame member attached to the pickup truck bed, the base frame member supporting a substantially planar roller platform member slidably engaged with the base frame member. The base frame member includes a pair of elongate rail members extending in parallel along a first longitudinal axis and adapted to engage a set of roller wheels provided on the bottom of the roller platform member. A substantially planar lift platform member is operatively connected to the roller platform member through a set of parallelogram linkages which permit the lift platform to be moved between a raised position coplanar with the roller platform member and a lowered position out of the plane of the roller member for convenient loading of the lift platform at ground level. In the raised coplanar orientation between the lift platform member and the roller platform member, the platform member pair are slidable together relative to the base frame member. A locking arrangement is provided to prevent the inadvertent sliding of the roller platform member relative to the base frame member when the pickup truck vehicle supporting the load lift apparatus is in motion.

A method is provided to inspect a resiliently deflectable O-ring which tends to distort under the influence of its own weight. The O-ring is placed on a transparent support member with the central axis of the O-ring in a vertical orientation. Light is directed toward the O-ring and through the support member to cause the O-ring to cast a shadow. The distance between portions of the shadow cast by diametrically spaced apart portions of the O-ring indicate diametral measurements of the O-ring. The distance between radial edge portions of the shadow cast by the O-ring indicates the thickness of the O-ring. To detect surface flaws in the O-ring, light is directed against a small area on the surface of the O-ring while it is rotated. A variation in the characteristics of the reflected light indicates the presence of a flaw in the surface of the O-ring. To provide for scanning of inner and outer surface areas of the O-ring to detect surface flaws, the O-ring may be rotated about an axis which extends perpendicular to the central axis of the O-ring and is tangential to a circle through the center of the cross section of the O-ring.
