An aluminum alloy gantry structure is used to support the LDW calibration target board. A Siemens servo motor and linear slide rail are equipped in the Z direction. The target board adopts a servo-driven synchronous belt transmission method for movement in the Z direction, achieving precise positioning, with a Z-direction movement speed greater than 150mm/s.

A hidden counterweight is installed inside the column of the gantry. The target board is designed with a 1:1 weight ratio, which can effectively reduce the operating load of the motor.

Secondary anti-fall chains and alarm switches are designed on both left and right sides of the target board. When the belt falls off or breaks, the system can effectively detect the fault and prevent the target board from falling, thus avoiding damage to people or vehicles.
