The high speed of 12,000 r/min covers both low-speed, heavy-load and high-speed, light-load operating conditions of ship deck machinery (such as winches and steering gear). The 45 MPa pressure adapts to the hydraulic pump requirements of small and medium-sized metallurgical and engineering machinery, avoiding the waste of testing resources caused by "a large horse pulling a small cart."

(2) Cost-effective energy-saving design

With an energy retransmission efficiency of over 85%, it recovers approximately 93.5kWh of electricity per hour at a full 110kW load, saving over 60% in annual energy costs compared to traditional resistive load test benches. It is particularly suitable for batch quality inspection (such as hydraulic pump factory testing) and short-to medium-cycle endurance testing in small and medium-sized enterprises.

(3) Flexible switching between multiple scenes

The load module supports rapid switching between three modes: high-pressure overflow (small metallurgy), proportional throttling (ship anchoring), and heavy-load loading (construction machinery). It can complete hydraulic transmission tests on three types of small and medium-sized equipment without replacing core components, thereby improving test bench utilization.

(4) High adaptability to industrial environment

The variable frequency inverter system has IP54 protection and forced water cooling, making it suitable for the dusty environments of metallurgical workshops and the humid environments of ship repair yards. It supports Modbus protocol and docking with the workshop MES system, allowing it to be integrated into existing production chains without additional modifications.

(5) High reliability and low maintenance cost

The dynamometer's core bearings are from the SKF Small and Medium-sized Industrial Heavy-Duty Series. The oil tank's three-stage filtration system reduces wear on hydraulic components, ensuring annual maintenance time of ≤30 hours. Key components come with a one-year warranty, reducing operational and maintenance pressure on small and medium-sized enterprises.
