LEBEN-DÄMPFUNGSTECHNIK GMBH - LEBEN manufactures industrial shock absorbers, vibration dampers, hydraulic buffers & crash-elements

The hydraulic industrial shock absorber of the C-series (COMPENSER®) is the ideal hydraulic buffer for storage and retrieval machines or smaller conveyor systems, crane systems, test stands etc. in light to medium mechanical engineering. Due to its short design, this hydraulic buffer (COMPENSER®) can be used in a spacesaving manner as limitation of the end position (as emergency end stop) in industrial applications. In addition, the low reset force allow operational pushin cycles at creep speed. Design & Function: The piston rod 2 enters the metering tube 3. The damping medium flows from the pressure chamber 6 through the throttle orifices 4 of the metering tube 3 into the volume balance chamber 5. The nitrogen gas between the outer tube 7 and the metering tube 3 is compressed and stores the energy required for the reset of the piston rod. When the piston rod 2 returns to the initial position, the damping medium flows back into the pressure chamber 6.

The preferred field of application for the (gas) hydraulic industrial buffer (COMPENSER®) of the S-series is in the medium to heavy engineering industry sector. As a heavy duty shock absorber it is used in large crane systems (e.g. harbour crane, shipyard crane or container crane), metallurgical plants, rolling mills, loading systems or as end stop integrated in a rail buffer stop. Design & Function: The gas-filled inner tube 2 enters the outer tube 9. The damping medium flows from the pressure chamber 6 through the throttle orifices 8 of the metering tube 7 into the volume balance chamber 5. The separating piston 4 simultaneously moves in the direction of the impact cap 1 and compresses the nitrogen gas filling. In the gas space 3, the energy is stored which is required for the reset of the inner tube. When the inner tube 2 returns to the initial position, the separating piston 4 moves in the opposite direction and presses the damping medium back into the pressure chamber 6.

The COMPENSER® of the CE-series is a nonreversible maintenancefree shock reducing element / shock absorber which can be used for emergency use, for example as a fall protection. If necessary, several deformation tubes (so-called crash element) can be installed in parallel as end stops. Design & Function: The crash element is attached to the support structure using the flange 3. In the event of an impact, the stamp (acting as a mandrel) 1 enters the deformation tube 2 and expands it. Applications: Automated storage and retrieval system | Conveyor system | Storage technology | Automation | Heavy duty | Heavy equipment | Engineering | Crashtest | Flight simulator | Special construction | Special machines | Actuator | Test device | Small parts warehouse | High-bay warehouse | STC | HRL | Storage and retrieval systems (AS/RS) equipment | non reversible | Leakage-free | Shuttle

The COMPENSER® of the KL-series is an industrial shock absorber for light mechanical engineering, e.g. handling equipment, small storage and retrieval machines and small crane systems. Due to the low reset force of the compression spring, this buffer of the KL-series is well suited for operational push-in cycles at creep speed. Design & Function: The piston rod 2 pushes the piston 6 into the pressure chamber 7. At the same time, the damping medium flows through the metering grooves placed in the outer tube 8, via the piston 6 and into the volume balance chamber 5. The return spring 3 is tensioned and, after the impact has occurred, pushes the piston rod 2 back to the initial position. By this the damping medium flows back into the pressure chamber 7.
