THE FAILURE POINT

Why Brake Accumulators Fail

Brake failure on a 45-ton Reach Stacker isn’t an option. Yet, standard accumulator bladders lose elasticity after 2,000 cycles, causing nitrogen permeation into the hydraulic oil. This results in “spongy” braking and pump cavitation.

Zhenke Technology counters this with high-density NBR (Nitrile Butadiene Rubber) bladders reinforced with a multi-layer polymer matrix. Our shells are forged from seamless Chromium-Molybdenum steel (35CrMo), ensuring zero fatigue even under rapid pressure fluctuations typical of Kalmar container handling.

Zero Permeation Guarantee

The difference is in the compound. While generic accumulators use standard rubber, we formulate our own NBR/Eco-Rubber blend. This reduces gas permeation by 85%, ensuring your Kalmar braking system maintains instant response even after months of operation.
