I. Engine Core Advantages (Mercedes-Benz Powertrain’s Biggest Highlight)
Extremely abundant low-speed torque, maximizing heavy-load power.
The 12.8L large-displacement six-cylinder engine delivers maximum torque at just 1100 rpm, handling hard soil, large stones, and wet, sticky debris without stalling or losing revs. Heavy-load climbing and full-load starts are effortless, offering significantly more power than later smaller-displacement models in harsh construction site conditions.
Simple and durable structure, virtually indestructible.
Euro II emission standard, eliminating the need for a urea system, DPF particulate filter, or complex electronic aftertreatment devices, resulting in fewer wiring and sensors. It is unaffected by low-quality diesel or dirty construction site environments; it can operate on regular diesel without the risk of aftertreatment blockage or torque limiting issues, making maintenance extremely easy.
Extremely Long Overhaul Cycle
The Mercedes-Benz OM460 is a heavy-duty machine derived from heavy trucks and mining trucks. Its robust body and dry cylinder liner design allow for 30,000-40,000 hours of normal maintenance without requiring major overhauls of the cylinder block and crankshaft. Many older used models still have excellent power after over 40,000 hours of operation, demonstrating durability far exceeding that of Hitachi’s own machines.
Smooth Power Output and Low Vibration
The inherent advantages of its large displacement engine result in stable idling and minimal machine vibration. Even during extended working periods, the machine remains stable, and the cab comfort surpasses that of comparable Japanese loaders.
II. Advantages in Overall Structure and Dry Operation Performance
Highest Digging Force Among All ZW310 Models
With a maximum digging force of 213kN, it cuts deeper into hard surfaces, compacted soil, and rock piles. The bucket retracts cleanly, preventing material sticking and resulting in high loading efficiency.
The chassis and boom are made of thicker and more robust materials. Early imported original chassis steel plates, articulated joints, and boom steel standards are higher than those of later domestically adapted models. Years of heavy-duty loading and driving on bumpy roads have resulted in a chassis less prone to deformation and cracking, exhibiting strong fatigue resistance.
The hydraulic system is classically tuned for smooth operation. Hitachi load-sensitive hydraulics ensure smooth, lag-free operation of complex movements (lifting + bucket retraction + steering), with precise micro-motion control. This provides excellent handling for precise material stacking and bulk cargo loading/unloading at docks, making work easier for experienced operators.
The four-wheel drive offers superior off-road capability. Equipped with a differential lock, it reduces the risk of slipping and getting stuck on muddy or potholed construction sites, providing better adaptability to off-road terrain.
