The DS331W is equipped with a W-shaped wireless LED/LCD display, clamp hangers, and can accurately measure key alignment parameters such as wheel camber and toe angle, providing data support for vehicle driving stability, tire wear control, and handling safety.

Users fix the left and right camera bracket fixing arms to the front of the lifting platform with screws, then install two 3-series camera assemblies on the fixed brackets respectively. In this way, the 3-series four-wheel aligner cameras and the target boards on the wheels form a fixed positional relationship, which will not change due to the lifting of the lifting platform. Users can realize convenient operation of the four-wheel aligner measurement by lifting the platform.
