Case Study: Hitachi Construction Machinery achieves uninterrupted ±1 cm 3D machine guidance precision with Proemion

Hitachi Construction Machinery delivers ±1 cm 3D machine guidance with Proemion

Hitachi Construction Machinery Co., Ltd needed to overcome the limitations of GNSS technology for its "Solution Linkage MG" 3D machine guidance system. The challenge was to maintain uninterrupted ±1 cm precision in environments with poor satellite reception, which required integrating data from a Robotic Total Station. This necessitated a robust wireless interface from vendor Proemion that could handle a proprietary data format and withstand harsh environmental conditions.

Proemion provided its CANlink® wireless 4000, which featured custom firmware developed to translate the Total Station's proprietary data. The device's rugged, weatherproof housing met Hitachi's rigorous testing standards. This solution from Proemion enabled Hitachi to offer the 3D guidance system with uninterrupted ±1 cm precision under all conditions, maintaining the company's high quality standards for its ZX200-7 hydraulic excavator.
