ABSTRACT:
The invention in a preferred embodiment contemplates a dual-lift hydraulic arrangement in which each of two hydraulic-lift systems employs a power integrator in the connection between a charged hydraulic accumulator and a hydraulic actuator for cable suspension of a load. The accumulator may be a single device serving the respective hydraulic systems, each of which terminates in a traction cylinder for operating a cable lift for its end of the load suspension. A single prime mover serves both power integrators, and the pressurized charge of the accumulator is advisedly set to accommodate (counterbalance) a predetermined average of the combined load on the two actuators. The arrangement lends itself to single-handed control of both hydraulic systems and to the corrective tilt orientation of a load which may be relatively heavy at one end and relatively light at the other end.
