Zylinderheber

A Zylinderheber, or cylinder lift, is a mechanical device used to raise heavy objects. It typically employs a hydraulic or pneumatic system to generate the lifting force. In its simplest form, a hydraulic Zylinderheber consists of a cylinder, a piston, and a reservoir of hydraulic fluid. Pumping the fluid into the cylinder beneath the piston causes the piston to extend, thereby lifting the attached load. When the valve is opened, the fluid is released, allowing the piston to retract and the load to be lowered.

These devices are commonly found in automotive repair shops for lifting vehicles, allowing mechanics access to the underside. They are also utilized in construction and industrial settings for moving heavy machinery or structural components. Zylinderheber can vary significantly in size and lifting capacity, from small, portable jacks used for changing a flat tire to large, industrial units capable of lifting hundreds of tons. The principle of operation relies on Pascal's law, which states that pressure applied to an enclosed fluid is transmitted undiminished to every portion of the fluid and the walls of the containing vessel. This allows a relatively small force applied to a small piston to generate a much larger force on a larger piston. Safety features such as locking mechanisms are often incorporated to prevent accidental lowering of the load.
