3030DD Piggyback Heavy Duty Long Stroke Chamber

The 3030DD Piggyback Heavy-Duty Long-Stroke Brake Chamber is designed for use with the 3030 long-stroke double-diaphragm series; it is a robust braking solution developed specifically to meet the rigorous demands of heavy-duty trailers and large trucks. The long-stroke design is engineered to ensure that—even during prolonged descents or heavy-load braking scenarios—sufficient pushrod travel is maintained to deliver effective braking force, even if the brake linings experience a certain degree of wear. Thanks to its innovative Piggyback structure, this product offers not only superior safety but also exceptional ease of maintenance, thereby significantly boosting operational efficiency for heavy-duty vehicles at service centers.
Operating at an air pressure of 10 Bar, this product demonstrates exceptional environmental adaptability, functioning reliably across a wide temperature range of -40°C to +80°C. To guarantee long-term reliability, the product comes with a 12-month warranty and has successfully passed a 72-hour salt spray corrosion test. We welcome customer customization requests—such as modifications to surface finishes or adjustments to pushrod configurations—and offer laser marking and custom packaging services. During the shipping and logistics phase, the product's air inlet is fitted with a threaded protective plug, while the pushrod is encased in a protective mesh sleeve and further enclosed in a protective bag; this comprehensive packaging strategy prevents transit damage and ensures the product is delivered in pristine condition.
