Changzhou, Jiangsu – March 2026 — Jiangsu Guchuan Machinery Co., Ltd., a leading manufacturer of hydraulic breakers and excavator attachments, announced the release of its latest generation of hydraulic breakers designed for superior performance, durability, and compatibility across various excavator classes.
With over a decade of experience in hydraulic system engineering, Guchuan Machinery continues to set new benchmarks in the construction equipment industry. The company’s updated SB series — including models such as SB30, SB50, and SB121 — introduces significant advancements in both design and material technology.
Each Guchuan breaker is built using advanced CNC machining and cryogenic nitrogen treatment, a deep-freezing process that strengthens steel by refining its crystalline structure. This treatment dramatically enhances wear resistance, increases structural stability, and reduces failure rates under continuous heavy impact.
“We’re not just building tools — we’re building long-term reliability," said a Guchuan senior engineer. “Our cryogenic treatment technology has extended the lifespan of key components such as pistons, chisels, and bushings by more than 30%."
The new Guchuan breakers employ auto-frequency tuning technology and optimized hydraulic flow design, enabling each unit to adapt its impact rate to the project environment automatically. This not only improves breaking efficiency but also minimizes vibration and backpressure, extending the life of both the breaker and carrier excavator.
With operating pressures ranging from 110–140 bar and oil flow rates of 40–150 L/min, Guchuan breakers cover a working range suitable for 1–50 ton excavators, ensuring maximum adaptability to various job site conditions — from small-scale trenching and road repair to large quarry and demolition work.
As part of Guchuan’s continuous international growth strategy, the company now serves customers across Asia, Europe, South America, and the Middle East, supported by an expanding network of distributors and authorized service centers.
“Our goal is not only to provide high-performance equipment but to be a partner in efficiency," said a spokesperson from Guchuan’s international sales team. “With reliable after-sales support and readily available parts, our customers can focus on the job, not the downtime."
Founded in 2010, Jiangsu Guchuan Machinery Co., Ltd. is based in Changzhou, Jiangsu Province, China, covering over 18,000 square meters and staffed by more than 120 skilled professionals. The company specializes in hydraulic breakers, quick couplers, and other excavator attachments, serving the global construction, mining, and demolition industries with full in-house R&D, production, and technical support capabilities.
