Four-Arm Precision for the Widest Windshields: CAP Introduces CAP727012 Four-Output-Shaft Wiper Linkage for Wide-Body Trucks and Special Vehicles

2026 07/23

[Hangzhou, China] – COMOTECH ASIA PACIFIC (CAP), a globally recognized OE specialist in professional wiper transmission engineering, is proud to introduce its most comprehensive single-unit linkage solution to date: the Four-Output-Shaft Wiper Linkage Assembly (Model: CAP727012). Purpose-engineered for the demanding visibility requirements of wide-body trucks and specialized heavy vehicles with high or low windscreen configurations, this parallel four-arm actuator system delivers complete, synchronized windshield coverage from a single motor drive — eliminating the need for multiple independent assemblies on the widest commercial cab front panels.
 
Four Parallel Output Shafts: Comprehensive Coverage from a Single Drive The defining engineering achievement of the CAP727012 is its four-output-shaft parallel configuration, simultaneously driving four independent wiper arms from a single motor input. The four shafts are positioned at a precisely calculated installation center distance of 475mm × 332mm × 332mm × 375mm — a deliberate asymmetric spacing designed to optimize blade sweep coverage across the irregular windshield geometry typical of wide-body trucks, airport ground support vehicles, and heavy industrial machinery. All four M8 output shaft threads deliver consistent torque to each arm, while the M20 tube sleeve mounting provides the structural rigidity required to hold the entire assembly stable under high-frequency operation and road vibration.
 
Engineered for High and Low Windscreen Truck Configurations The CAP727012 addresses one of the most technically challenging segments of commercial vehicle wiper design: vehicles featuring both high and low windscreen panels, common in European long-haul trucks, articulated special-purpose vehicles, and off-highway construction equipment. By spanning the full width with four synchronized arms at optimally spaced intervals, the CAP727012 ensures that both upper and lower glass panels receive consistent wiper pressure and coverage, eliminating the incomplete clearing zones that single or dual-arm systems leave on multi-panel cabs.
 
European-Compliant Surface Treatment — Customizable on Request The standard surface finish on the CAP727012 is a specialized chromium-free electroplating layer meeting European environmental standards for chemical substance restrictions. For customers requiring alternative protection specifications, the surface treatment can be changed to general galvanizing upon request — providing flexibility for diverse procurement requirements across different regional markets and end-use environments. The low-noise, long-life design philosophy applied across all CAP linkage products ensures that the CAP727012 delivers smooth, quiet operation throughout its service life.
 
ISO9001-Certified Manufacturing, High-Volume Global Supply Manufactured in Hangzhou, China under strict ISO9001-certified quality management, the CAP727012 is backed by a supply capacity of up to 500,000 units per cycle. Flexible FOB shipping from Ningbo and Shanghai ports under L/C or T/T terms makes it accessible to truck manufacturers, Tier-1 wiper integrators, and international aftermarket distributors serving the heavy vehicle maintenance sector worldwide.
