Abstract: An apparatus for bidirectionally translating and positioning loads under tension includes a linear hydraulic actuator suspendible from a hoist such as a crane and is useable to support, raise and lower heavy loads in precisely controllable small incremental distances. The apparatus utilizes a strain-gauge type load cell positioned between an upper end of the actuator and an upper anchor connector eye suspendible from a crane. A digital display device operatively coupled to the load cell provides an accurate indication of static weight of a load supported by a load connector eye attached to a lower end of a piston rod protruding from the actuator, and accurate and immediate indications of any load weight deviation resulting from contact of a load with an obstruction while being raised or lowered. A pressure relief valve is provided to enable flow of hydraulic fluid from the actuator cylinder to a fluid reservoir to prevent inadvertent over-pressuring of the cylinder.
