Abstract
A radiator hoist and positioner includes an upright post supporting a rotatable swing arm. An extensible hoist line is mounted on the swing arm. A swivel connects a yoke structure to the hoist line. Rotatably mounted on the yoke structure are two clamp mechanisms; the clamp mechanisms are aligned for rotation. A pair of opposed pad members included in each clamp mechanism are advanced and retracted by an activator mechanism to clamp and unclamp a radiator. A clamped radiator is positioned as desired by rotating the clamp mechanisms, the yoke structure and the swing arm, and by extending or retracting the hoist line.
Claims8
An improved radiator hoist and positioner comprising:
- an upright post;
- a swing arm supported on the upright post for rotation about a first, substantially vertical axis;
- an extensible and retractable hoist line mounted on the swing arm;
- a yoke structure mounted on the hoist line for rotation about a second, substantially vertical axis;
- at least two clamp mechanisms each including a pair of opposed pad members having generally planar radiator contacting surfaces defined thereon and further having an actuator mechanism (1) for advancing and retracting the pad members toward and away from each other so as to clamp and unclamp a radiator between the radiator contacting surfaces, and (2) for applying a force to the pad members so as to retain the pad members in the position in which the radiator is clamped, the clamp mechanisms mounted on the yoke structure for rotation about a common, substantially horizontal axis the clamp mechanisms each further including a base plate, and the actuator mechanism including a trunnion member, links connecting the pad members and the trunnion member, and means for drawing the trunnion member toward and away from the base plate, whereby the links are moved, respectively, toward and away from the base plate and the pad members are moved, respectively, toward and away from each other;
- whereby a radiator is clamped, and raised or lowered by retracting or extending the hoist line, or rotated about the axes of rotation of the swing arm, yoke structure and clamp mechanisms, to a variety of desired positions.
