Description
The E6125F hydraulic excavator adopts the mature mid-digging platform of Lingong, with a new load-sensitive hydraulic system, a new engine and an electronic control system, which is energy-saving, emission-reducing, comfortable and reliable. Provide customers with a new product that adapts to the working conditions of loose materials such as earth and stone. Energy-saving and high-efficiency – supercharged and inter-cooled engine, with high fuel injection pressure, strong power and high productivity; sufficient combustion, meeting the national three emission requirements, energy saving and environmental protection; electronically controlled unit pump structure, with slit filter at the inlet of the fuel injector , To ensure the cleanliness of the fuel entering the injector, and the fuel oil product adaptability; the engine performance is carefully adjusted to not only meet the high-speed section efficiency requirements, but also reduce the fuel consumption in the middle-speed section of the economic zone; the engine has “five modes, ten gears” The setting of ?position? automatically adjusts the power matching, optimizes the operation mode, and meets the customer’s multi-condition selection requirements; the unique automatic idling function reduces to different speeds according to different operations of the user, and the energy saving and noise reduction effects are more obvious. The new load-sensitive hydraulic system can realize fine and load-independent operation, has excellent maneuverability of small excavators, and is highly efficient and energy-saving; the bucket has fast digging speed and strong digging ability; the stick speed is fast, and the efficiency is high when performing flat operations; The regeneration function of the working device can supply part of the pressure oil in the small cavity of the oil cylinder and the pressure oil output by the pump to the large cavity of the oil cylinder at the same time. The recovery speed of the stick is fast and stable, and the work efficiency is improved. Reliable and durable – reinforced boom/stick: structural parts have the lowest failure rate in the industry; reinforced bucket: the wear parts (front, two sides and bottom) of the bucket are all welded with super wear-resistant materials. The average service life of the bucket is more than 20% longer than that of the traditional model; strengthened “X” walking frame: strengthened design of the beam structure with concentrated stress, so that the strength of the cross section is increased by more than 35% than that of the traditional model, and it is more suitable for harsh working conditions And heavy load conditions. Comfortable and convenient – Maintenance points are concentrated on one side: the electronically controlled unit pump is arranged on the cylinder block and is directly driven by the camshaft through the tappet. The structure is compact, the rigidity is good, so the vibration is low, the noise is low (less than 96 decibels), and the operating environment is comfortable; Except for the starter and the supercharger, the maintenance points of the engine are concentrated on the same side of the engine, which is easy to maintain; the open hood opens at a large angle: the left and right hoods of the excavator and the top hood have a large opening angle, which is very convenient for maintenance; Centralized maintenance points: centralized electrical layout: EECU, complete fuses, and relays are centrally arranged in the left front cover (adjacent to the air filter). The back of the cover is also printed with a layout diagram, which is very convenient for maintenance and repair; side-by-side heat dissipation: in the engine The cooler, the water diffuser and the hydraulic oil radiator are arranged in triple parallel, which has good heat dissipation effect and is convenient for cleaning and maintenance.
