Products & Range Coverage
A&S MACHINERY CO., LTD. delivers an extensive inventory of wiper and washer assemblies and core components to support diverse excavation, earthmoving, material handling, and roadbuilding requirements:
• Machine & Wiper System Compatibility: Engineered for a broad range of Caterpillar equipment—including medium/large excavators (e.g., CAT 320, 336, 349), wheel loaders (e.g., CAT 950, 966, 980), and track-type tractors (e.g., CAT D6, D8, D9)—our parts ensure exact voltage compatibility (12V/24V), precise mounting alignment, and mechanical integration with original factory structures to guarantee a perfect match.
• Complete Wiper & Washer Components: 1. Drive & Linkage Assemblies: Heavy-duty wiper motors, reduction gearboxes, and wiper linkage arm assemblies; 2. Terminal Wiping Components: Corrosion-resistant wiper arms and high-strength rubber/silicone blades designed for extreme cold and intense sunlight; 3. Washing & Spraying System: High-output washer pumps, fluid reservoirs, multi-angle spray nozzles, pressure-resistant hoses, and one-way check valves.
• OEM & Heavy-Duty Aftermarket: We offer genuine Caterpillar wiper/washer accessories alongside rigorously tested heavy-duty aftermarket parts certified for high-dust mining and strong UV exposure, delivering equivalent efficiency and extended durability at a cost-effective price point for global fleets.
Supply Chain & Logistics
We maintain a robust operational infrastructure designed to support global machinery climate maintenance component procurement through direct supply channels, delivering reliable stock availability and rapid dispatch to build trust with international buyers.
• Seasonal and Ready-to-Ship Inventory: We maintain large-volume stock of high-demand CAT excavator and loader wiper motors, linkage assemblies, and high-wear wiper blades specifically tailored for rainy season and winter maintenance surges. We also guarantee direct dispatch upon order confirmation to minimize unplanned equipment downtime caused by reduced visibility and safety compliance violations resulting from wiper failures.
• Anti-Vibration and Moisture-Proof Packaging: We implement specialized industrial packaging standards for precision wiper motors and linkage assemblies, utilizing moisture-proof and shock-resistant independent bubble wrap, thickened honeycomb corrugated master cartons, and rust-preventive encapsulation to ensure parts remain free from humidity corrosion and mechanical impact during transcontinental ocean or air transit.
• Consolidated Sourcing: We support overseas clients by consolidating wiper systems and washer pumps alongside glass, rearview mirrors, and cab panels into bundled shipments, maximizing container space utilization and significantly reducing international freight costs.
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 Durability Solutions: We address common field issues in extreme working environments, such as high-dust mining operations, sub-zero freezing zones, and desert sun exposure areas, where wiper blade rubber rapidly hardens and cracks, mud buildup causes motor overload and burnout, or winter washer fluid freezes. We also provide professional engineering upgrades, including upgraded tear-resistant silicone wiper blades, heavy-duty wiper motors featuring thermal overload protection, and freeze-resistant washer tubing assemblies.
• Wiper Troubleshooting and Diagnostics: We address common user concerns regarding wiper faults by providing professional diagnostic and replacement guidance. This includes instructions on how to check linkage ball joint wear and motor gearbox lubrication states to avoid unnecessary system-wide replacements, alongside rapid clearing and adjustment methods for weak washer pumps, aged leaking hoses, or sediment-clogged spray nozzles.
• Expert Technical Support and Safety Guidelines: We provide technical documentation covering wiper arm downward pressure adjustment standards, motor waterproof connector wiring specifications, and routine cleaning recommendations for glass surfaces burdened with oil film and abrasive sand.
