HD21 Series

Small versatile units with a lower capacity than other Oleo buffers and are often found on overhead and small gantry cranes

An industry standard buffer with a robust design that can be impacted repeatedly. With six different buffer units available within the series, ranging from Type 21-50 (50mm stroke) to Type 21-300 (300mm stroke), making them suitable for a wide range of applications.

Product Advantages

Efficiency of up to 90%, compared to 50% for spring buffers, allows a reduction in damaging forces and/or installation length.
Performance can be optimised for one or more impact scenarios; reaction forces will then be optimal at any velocity.
Durable against prolonged exposure to chemical corrosion, weathering or UV radiation.
Protective bellow design has passed extensive environmental, endurance and particulate testing.
Negligible energy passed back to mass after impact.
