Working principle
Large bore hydraulic damping and gas or air/oil accumulator systems absorb high impact energy while controlling return behavior.
Construction
Heavy cylinders, piston rods, oil chambers, gas or air accumulators, custom orifices, flanges, bellows and safety cables.
Applications
Cranes, rail systems, steel industry, coal handling, automated storage, trolley cranes and heavy production lines.
Selection checks before choosing a model
1. Choose the construction
Separate routine stopping from emergency protection. Compare EI gas return, ED accumulator arrangements and application-specific HS configurations.
2. Match the model ratings
Check mass, impact speed, drive force, stroke, energy per stop and hourly energy together. Return requirements and accumulator options affect the permitted duty.
3. Prepare review data
Provide stopping distance, reaction-force limit, cycle rate, mounting and outdoor/dust conditions. Confirm the exact metering and return configuration.
Sources and selection boundaries
Catalogue values apply to the stated model and configuration. Missing ratings require confirmation; similar appearance is not proof of interchangeability.
