22T Mobile Material Handler (WZY22-8) - Tracked

The WZY22-8 is a 22-ton wheeled material handler powered by a Cummins QSF3.8T3 diesel engine, delivering 93 kW at 1900 rpm with a 281 L fuel tank — built for extended, high-duty-cycle operation.

Its hydraulic system features dual-pump confluence with a maximum flow of 2×152 L/min and 30 MPa operating pressure. Hydraulic pilot control delivers smooth, precise movements, while the 228 L hydraulic oil tank ensures sustained system stability.

Performance highlights include a 14.5 rpm slewing speed and a two-speed travel system (3.3 / 5.7 km/h) balancing heavy-load tractive effort with efficient site-to-site mobility, with a working cycle of 13–20 s. Equipped with a 5-tine semi-closed orange peel grab (0.6 m³), a 6,200 mm boom and 4,200 mm stick, it offers a maximum grabbing reach of 11,354 mm, height of 9,181 mm, and depth of 5,124 mm — ideal for scrap recycling, port bulk handling, and waste management applications.
