Dellner Dampers AB specialises in solving vehicle dynamics by developing a unique damping product optimised for your specific application. Supplier of a wide range of customer standard solutions, the Dellner factory is also adapted to manufacture shock absorbers of unusual sizes and extreme specifications.

SHOCK ABSORBER APPLICATIONS

Dellner shock absorbers cater to a wide range of trains and trams worldwide. Additionally, Dellner supports specialised vehicle and industrial applications including:

• Rolling stock bogies

DAMPING PRODUCTS

• Primary and secondary suspension dampers
• Roll dampers (e.g. 2.5m long between cars)
• Yaw dampers
• Secondary coupler dampers
• Displacement sensitive dampers
• Hydraulic Buffers
• Support springs with hydraulic damping

The Dellner shock absorber is designed to meet the market demand for long damper life and extensive functionality. Substantial lab and field-testing are performed to guarantee full product functionality and long trouble-free life. Each damper is individually tested before delivery.

TECHNICAL HIGHLIGHTS

Large hydraulic flow and pressure areas on valve components ensure that the Dellner damper maintains its performance at frequencies over 20Hz and at relative velocities of 2m/s. The 80mm piston diameter of our yaw dampers results in high dynamic stiffness. Depending on type of damper the damping characteristic can be set from 10 to 4,000kN/m/s. All dampers are fully reconditionable.
