At Alta we make sure that every major wiper system that goes to an assembly plant is well designed, manufactured with acceptable tolerances and tested per OE customer design specifications.
Recognizing that wiper systems have safety implications, we make sure extensive design and production validation testing is performed. This ensures that drivers can see properly in adverse weather conditions. Durability and Reliability are designed into the product. Wiper systems are tailored to each vehicle line so that drivers get optimum performance.
Description of Systems
When selecting a wiper system one must take into account the size of the glass, mounting position, and application. Other consideration include if you would like a "wet system" that requires a fluid container with tubing kit or a "dry system" that does not have washing capabilities.

Different Types of Systems
1) Internal Linkage Motor
Used primarily on small glass. Popular in the agricultural, specialty, and marine industries. These motors have the linkage controlling the wipe angle inside the motor. |
 |
2) Unitized Assemblies (Pony Direct)
Used on large glass. These assemblies can utilize the largest arms and blades available. One motor operates one arm and blade. These systems are the most versatile but require a larger mounting space than the internal linkage motor. |
 |
3) Unitized & Loose Linkage Assemblies (Single Motor / Dual Arm)
Seen most often in automotive and motor home applications. One motor is attached to a linkage system that controls two pivot shafts that are connected to the arms and blades. Both arms and blades move together at the same time.
Pantograph System - This single motor system uses a bicycle style linkage, which makes the arms and blades park in the up / vertical position in the middle of the glass.
Conventional System - This single motor system uses a double drive unit for the transference of motion from the passenger side to the driver side. This system is much like what you would see on a car. The arms and blades park in the down position.
