The Underground LHD Hydraulic Tester is a professional testing device specially designed for the hydraulic system of underground LHD (Load-Haul-Dump Machine) in mines, and it is an ideal tool for hydraulic system fault diagnosis. The device as a whole has the advantage of lightweight and portable; even in the narrow and complex working environment underground, workers can easily carry and operate it, greatly reducing the labor intensity of on-site testing.​ In terms of core performance, relying on precise sensing technology and mature data analysis algorithms, this tester can quickly capture key parameters of the hydraulic system such as pressure, flow rate, and temperature, realizing accurate data collection. Its error rate is far lower than the industry standard, providing reliable data support for fault location. Whether it is hidden faults of hydraulic pumps and valves, or common problems such as pipeline leakage, the device can quickly diagnose them, helping workers shorten the fa
