The suspension test bench creates vibrations in the vehicle's suspension, thus capturing the play in the suspension. The SZ-4H uses hydraulic power and is suitable for inspecting vehicles up to 3.5 t. The movement of the equipment pallets is both horizontal and vertical, thus improving the testing process. The plates are galvanized to ensure durability and the surfaces of the plates are engraved to ensure adhesion. The equipment is equipped with an LED flashlight for a smooth inspection of the chassis.
