Attachments/Hammers

Products & Range Coverage
A&S MACHINERY CO., LTD. delivers an extensive inventory of hydraulic hammer assemblies and wear parts, eliminating procurement gaps across global machine fleets:
• Machine Compatibility: Engineered for Caterpillar series from mini/compact excavators (CAT 301.7–308), medium/heavy units (CAT 320, 330, 336, 345, 374), to ultra-large excavators and skid steer loaders, ensuring exact alignment with mounting brackets, auxiliary hydraulic flows, and operating pressures.
• Complete Breakers & Wear Parts: 1. Breaker Assemblies: Triangular, box-silenced, and side-mounted hydraulic breakers; 2. Chisels & Internal/External Wear Parts: High-strength alloy chisels (point, moil, wedge, blunt); upper/lower wear-resistant copper guide bushings; precision heat-treated pistons and cylinder assemblies; imported hydraulic seal kits and accumulators; nitrogen charging components; high-strength through-bolts, side plates, and shock absorbers.
• OEM & Heavy-Duty Aftermarket: Offering genuine OEM Caterpillar breaker parts alongside rigorously tested aftermarket alternatives manufactured from wear-resistant special steels, guaranteeing equivalent impact energy efficiency and extended wear life in extreme environments.

Supply Chain & Logistics
We maintain a robust operational infrastructure designed to support global heavy machinery and hydraulic attachment procurement through direct supply channels, delivering reliable stock availability and rapid dispatch to build trust with international buyers.
• Ready-to-Ship Inventory: We maintain large-volume stock of high-demand chisels in various specifications, seal kits, guide bushings, and medium to large hydraulic breaker assemblies to ensure immediate order processing and rapid dispatch upon confirmation, directly minimizing equipment downtime for mining sites and construction projects.
• Global Shipping and Industrial Packaging: Our international logistics framework utilizes efficient air freight courier services and express lines for urgent chisels and seal kits, alongside ocean freight and specialized heavy transport for breaker assemblies and heavy steel components, ensuring secure delivery covering core mining and infrastructure markets across North America, South America, the Middle East, Europe, Australia, Southeast Asia, and Africa.
• Anti-Corrosion and Heavy-Duty Protection Standards: We implement rigorous industrial packaging standards specifically designed for elongated heat-treated chisels utilizing anti-rust spray coatings and impact-resistant wooden crating, alongside robust steel pallet fixation and fumigation-free wooden box sealing for precision hydraulic seals and breaker bodies to guarantee that products withstand long-distance ocean transport without damage.

Engineering Solutions & Technical Support
Our technical framework focuses on resolving field-level operational challenges to eliminate equipment downtime, moving beyond simple parts distribution to deliver comprehensive engineering and service capabilities.
• Application-Specific Breaker Solutions: We address common field issues in high-hardness granite extraction, abrasive ore crushing, underground narrow tunnel operations, and massive reinforced concrete demolition, where chisels experience burning, rapid alloy tip wear, or through-bolt fatigue failure. We also provide professional engineering solutions, including customized wear-resistant alloy chisel selections, high-durability bushing upgrades, and impact-resistant structural optimizations.
• Hydraulic Flow and Pressure Expertise: We solve hydraulic matching issues frequently encountered by global buyers when cross-brand selecting or installing hydraulic breakers regarding mismatched Caterpillar machine hydraulic flow rates, operating pressures, and return oil backpressures, and we provide professional guidance on piping configurations, relief valve adjustments, and accumulator parameter matching to ensure breaker striking efficiency reaches peak levels without compromising machine hydraulic systems.
• Expert Technical Support and Safety Guidelines: We provide professional technical guidance covering breaker initial installation air bleeding, daily grease lubrication intervals to prevent dry firing and chisel burning, nitrogen pressure testing procedures, and safe operation protocols. Clear warranty policies ensure complete peace of mind for global mining contractors, demolition firms, equipment rental businesses, and parts distributors.
