Engineering Equipment Wiper Demand Verification Guidelines
Precisely confirm the customer’s engineering machinery type (excavator/crane/road roller), wiper installation dimensions, motor voltage (12V/24V), performance requirements (e.g., high-low temperature resistance, salt spray resistance), and clarify the need for customized design.

Technical Solution & Order Process for Engineering Equipment Wipers
Select the optimal wiper assembly type (one-drive-one single-blade or upright configuration) per customer requirements, deliver targeted technical solutions and samples, support customers with installation testing and performance validation, and finalize the official order upon sample qualification.

Engineering Wiper Mass Production & Quality Control
Initiate mass production on automated lines per order requirements, implement full-cycle quality control compliant with the ISO/TS16949 quality management system, and conduct comprehensive testing—including power performance testing, noise level testing, and heavy-duty durability testing—to ensure the wiper assembly quality meets stringent engineering standards.

Engineering Wiper Logistics & After-sales Service
Organize international logistics services (covering full-range supporting services like customs clearance and freight forwarding), provide professional installation and commissioning guidance upon delivery; set up dedicated after-sales files, deliver warranty-period maintenance and replacement services, and conduct regular follow-ups on equipment operation status.

How will we design it for you?
Basic Vehicle & Adaptation Information
- Model and production year of the target vehicle (e.g., specific bus, public transport vehicle, school bus, or engineering vehicle model).
- Dimensions and curvature of the windshield (length × width, radius of curvature) to avoid wiping blind spots or interference between the wiper arm and glass.
- Mounting hole specifications (hole spacing, diameter, and shape of the mounting base).
- Length and swing angle range of the wiper arm, as well as the connection interface standard between the wiper arm and motor.
- Space limitations for motor installation (e.g., length, width and height of the reserved installation area) and motor voltage (24V is commonly used for commercial vehicles, while 12V for passenger vehicles).
- Operating environment requirements (e.g., high and low temperature resistance range, salt spray and dust resistance, applicable altitude).
- Wiping performance indicators (e.g., wiper frequency levels, noise reduction requirements, wiping cleanliness rate standards).
- Special working condition requirements (e.g., whether it needs to be compatible with the camera field of view for autonomous vehicles, whether anti-freezing or anti-icing functions are required).
- Preferred wiper type (e.g., opposed overlapping type, parallel type, vertical type, etc.).
- Certification standards for the target market (e.g., CE, DOT, ISO/TS16949 and other certification requirements for international trade).
- Appearance and material requirements (e.g., wiper blade rubber material, surface treatment process of wiper arms).
- Estimated order quantity and delivery lead time.
- Compatibility requirements with the customer’s existing wiper motors/control systems.
Testing and Inspection Standards
- Wiping Cleanliness Rate Test: Verify whether water marks remaining on the glass surface meet the specified standards; for commercial vehicles, a wider field of view coverage is required.
- Durability Test: Simulate tens of thousands of wiping cycles to verify the wear resistance of wiper blades and the service life of motors.
- Noise Test: Control the noise level during the wiping process to enhance the driving and riding experience.
- Motor Performance Test: For different voltage specifications of 12V and 24V, test the motor power, rotational speed stability, and overload protection capability.
- Test the mounting hole positions, dimensional tolerances, and interface compatibility of the wiper assembly to ensure precise matching with the customer’s vehicle models.
