Selection and installation

Automated warehouses, rail systems, gantry cranes and heavy production lines. Review hourly energy and the required return cycle.

Series working principle

Metered hydraulic flow absorbs energy, while the accumulator accommodates displaced oil. Orifice configuration and accumulator options depend on the application and cycle rate.

Catalog application and mounting notes

The ED1.5x12 heavy-duty buffer has a published 300 mm stroke. Confirm the impact remains aligned with the buffer axis and review the model dimensions and mounting space before final selection.

Engineering limits to confirm for this model

Published data below describes the model. A missing value needs confirmation; it is never a passed check. Use the cited model drawing and operating conditions when requesting a review.

Temperature ranges are series catalog references. Confirm the fluid, seals and ordered configuration; an optional range is not a standard-model rating.

Return force is separate from allowable impact force and drive thrust. BA denotes the optional bladder accumulator; do not assume it is fitted.

Catalog operating conditions

  • Catalog cycle limits: 60 cycles/hour with BA, 30 without BA. Also check energy per cycle, hourly energy, temperature and full return before the next impact.
  • For impact speeds above 4.5 m/s or any side loading, request engineering review. The energy tables assume linear impact.
  • For strokes of 300 mm or more, the catalog advises against rear-flange-only mounting; review front-and-rear flange or foot mounting.
  • Below 5% of the maximum rated energy per cycle, the catalog calls for a smaller model. Confirm low-energy damping for the actual application.
