In terms of performance, the Ensign 677HV boasts an impressive bucket capacity ranging from 3.5 to 7.0 cubic meters, enabling it to handle large volumes of materials such as gravel, sand, and dirt in a single pass. With a rated load capacity of 7500 kg and an overall operating weight of 25220 kg, it delivers substantial lifting and carrying power. The maximum traction force of 200 kN and a maximum digging force of 200 kN allow it to tackle tough terrain and digging tasks with ease. It can climb slopes up to 28 degrees, ensuring good mobility in hilly or uneven work sites.
Maneuverability is another strong suit. The minimum turning radius (outside of the bucket) is 7540 mm, and for the tire outside, it is 6680 mm, which helps it navigate through narrow spaces and make tight turns on the job site. The vehicle width (outside of the wheels) is 3130 mm, and the overall dimensions (length * width * height) are 9460 * 3300 * 3485 mm, striking a balance between size for productivity and the ability to access different work areas. The wheelbase is 3500 mm and the tread is 2380 mm, contributing to stable operation during lifting, transporting, and maneuvering.
Powering the Ensign 677HV is an engine model WP10G286E301. This engine features a vertical, in – line layout with electronic – controlled high – pressure common rail technology, water – cooling, a four – stroke cycle, and supercharging. It provides a rated power of 210 kW at a rated speed of 2200 r/min and a maximum torque of 1185 N•m, ensuring sufficient power output for all operating conditions while meeting China’s National III emission standards for environmental friendliness. The transmission system consists of a single – stage single – phase three – element torque converter and a fixed – shaft electro – hydraulic shifting transmission with 4 forward and 3 reverse gears.
Operational efficiency is enhanced by features like a three – item summation time of ≤10.3 s, which refers to the combined time for lifting, dumping, and lowering operations, reducing cycle times and boosting productivity. The unloading angle is 45 degrees, the unloading height is 3440 mm, and the unloading distance is 1440 mm, facilitating convenient and accurate dumping of materials. The minimum ground clearance is 440 mm, preventing damage to the undercarriage when working on rough surfaces.
For operator comfort, although not elaborated in detail here, the design likely takes into account aspects such as a spacious cab, ergonomic controls, and possibly features to reduce noise and vibration, ensuring that operators can work efficiently and comfortably for extended periods.
