[Hangzhou, China] – COMOTECH ASIA PACIFIC (CAP), a globally trusted Sino-French OE specialist in professional wiper system engineering, is pleased to spotlight its precision-engineered Pantograph Double-Arm Wiper Arm (Model: CAP315095). Purpose-built for the demanding visibility requirements of excavators and bulldozers, this double-arm wiper assembly is currently exported to France for active use in heavy construction machinery — a market validation that speaks directly to the product's compliance with European engineering and performance standards.
Dual-Arm Pantograph Design: Full Coverage for Wide Construction Windscreens The CAP315095 uses a pantograph (parallel double-arm) configuration, which maintains the wiper blade in a consistent vertical orientation throughout its entire sweep arc. Unlike single-arm designs that allow the blade angle to change as it traverses the windscreen, the pantograph mechanism ensures uniform contact pressure and a true parallel sweep across the full glass surface. This is particularly critical for the wide, flat windscreens of excavators and bulldozers, where uncleared zones can create dangerous blind spots during earthmoving, demolition, or grading operations.
Engineered for 700mm Heavy-Duty Blade Compatibility The CAP315095 is specifically designed to mount and drive 700mm wiper blades — a length appropriate for the large windscreen panels of heavy construction equipment cabs. The blade attachment uses a U-connection with integrated nozzle washer mount, providing a secure, flutter-free blade interface while simultaneously enabling washer fluid to be delivered directly to the blade contact point. The U-width of 16.2mm and C12×M8 joint hole provide a standardized, robust connection that accommodates the mechanical stress of driving a heavy blade against the high-pressure aerodynamic forces encountered when machines are operating in open, windswept environments.
12N Constant Blade Pressure Over a 573mm Sweep Radius The arm delivers a calibrated 12N blade contact pressure across its 573mm sweep radius — precisely engineered to maintain consistent windscreen clearing without scratching the glass or overloading the wiper motor. Insufficient blade pressure causes streaking and incomplete clearing; excessive pressure accelerates blade wear and motor fatigue. CAP's 12N specification represents the optimal balance for heavy construction equipment cabs, where wiper systems may run continuously for hours during rainy or muddy work sessions.
UV-Resistant Low-Glare Black Powder Coating: Built for Outdoor Endurance All external surfaces of the CAP315095 are finished with a spray black plastic powder coating controlling reflectivity to 20–30%, the same low-glare specification applied across CAP's professional wiper arm range. This matte finish resists UV radiation and physical abrasion — critical for equipment that spends years operating outdoors in direct sunlight, dust, and rain. The controlled low reflectivity also eliminates glare artifacts on the cab windscreen interior that could distract or fatigue the operator during extended shifts.
ISO9001 Quality, Exported to France Manufactured at CAP's Hangzhou facility under ISO9001-certified quality management with a supply capacity of 500,000 units, the CAP315095 is an established export product serving the French construction machinery market. At USD 100 per unit with FOB shipping from Ningbo and Shanghai, it offers international construction equipment dealers, OEM integrators, and aftermarket distributors a precision-engineered, market-validated wiper arm solution for the most demanding heavy machinery applications.
