Abstract
A lifting device for containers comprises at least one hydraulic cylinder arranged on a support frame with a piston and piston rod and at least two, spaced-apart horizontal guiding cross-bars. Lengthwise displacement of the piston rod is transformed into a synchronous upward and downward movement by at least one angle lever pivoted on the support frame. The at least one angle lever comprises two lever arms, one of the lever arms being connected to the piston rod and the other of the lever arms being connected to one of the guiding cross-bars. The guiding cross-bars are connected to a load receiving device for the container and are guided on vertical support pillars of the support frame at both ends for lifting and lowering the container.
Claims15
A lifting device for containers which can be handled by means of container handling equipment, said lifting device comprising:
- at least one hydraulic cylinder arranged on a support frame with a piston and a piston rod,
- at least two horizontal guiding cross-bars spaced apart from each other, wherein lengthwise displacement of said piston rod is transformed into a synchronous upward and downward movement of said horizontal guiding cross-bars, said horizontal guiding cross-bars connected to a load-receiving device for the container, said horizontal guiding cross-bars being guided on vertical support pillars of the support frame at both ends, for the lifting and lowering of the container,
- wherein transformation of the lengthwise displacement of said piston rod into the upward and downward movement of said horizontal guiding cross-bars is accomplished by at least one angle lever pivoted on said support frame, said at least one angle lever comprising two lever arms, one of said lever arms being connected to said piston rod and the other of said lever arms being connected to one of said guiding cross-bars.
