device for lifting and moving heavy gegenstaende.

摘要

An arrangement is proposed for hoisting and transporting heavy objects, in particular a gantry for raising and transporting hatch covers on ships. The bridge forming the gantry is provided with travelling supports, on each of which two unilaterally supported levers are arranged, which can be raised by way of hydraulic cylinders. In the area of the free end of each lever a retractable and extendable bolt is provided which engages in a corresponding recess or an eye of the hatch cover. IMAGE
