48T Mobile Material Handler (WZYS48-9) - Tracked

The WZYS48-9 is a 48-ton super-heavy-duty dual-power tracked material handler, the dual-power flagship of the series, integrating both a diesel engine and a three-phase electric motor for flexible switching between operating modes. In diesel mode, a 194 kW engine (2200 rpm rated / 2000 rpm operating) with a 454 L fuel tank delivers mobile heavy-duty performance for off-grid, outdoor operation. In electric mode, a 132 kW standard or 160 kW optional motor (380V / 50Hz, 1485 rpm) provides zero emissions, low noise, and low operating cost for indoor and fixed-station work. One machine, two power sources — balancing mobility and economy.

The hydraulic system features dual-pump confluence with a maximum flow of 2×280 L/min in diesel mode and 2×208 L/min in electric mode, at 32 MPa operating pressure. Hydraulic pilot control ensures smooth compound movements and strong gripping force, while the 390 L hydraulic oil tank supports sustained heavy-duty stability.

The tracked undercarriage offers a low ground pressure of just 0.089 MPa, excellent mobility, and 290 kN maximum traction, with travel speeds of 3.1 / 5.1 km/h (diesel) and 2.3 / 3.8 km/h (electric). An 8,200 mm boom and 6,300 mm stick are paired with a 5-tine semi-closed orange peel grab available in 1.0 m³ and 1.2 m³ capacities, delivering a maximum grabbing reach of 15,472 mm, height of 12,684 mm, and depth of 7,572 mm. With dual-power switching and multiple grab configurations, it is widely suited for large scrap processing, port bulk handling, waste-to-energy, and heavy industrial yards — a flagship solution balancing environmental compliance and heavy-duty efficiency.
