  • Patent number: 4506866
    Abstract: A vehicle hoist has an inclined column along which a carriage having normally horizontal support members is moved. The carriage is moved by a hydraulic cylinder and engages the column in a ratchet-like fashion allowing upwards movement but preventing the lowering of the carriage unless a release mechanism is actuated simultaneously with the hydraulic valve governing the cylinder. The invention improves safety and provides smooth surfaces about the column.
