China Sdlg E6125f 12 Ton Hydraulic Excavator with Mature MID-Digging Platform of Lingong

Product Description

SDLG E6125F 12 ton hydraulic excavator with mature mid-digging platform of Lingong
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, high fuel injection pressure, strong power, high productivity; full combustion, meeting the national three emission requirements, energy saving and environmental protection;
The structure of the electronically controlled unit pump, the inlet of the injector channel is equipped with a slit filter to ensure the cleanliness of the fuel entering the injector, and the fuel oil quality is adaptable;
The engine performance is carefully adjusted to not only meet the high-speed section efficiency requirements, but also reduce the fuel consumption in the medium-speed section economic zone;
The setting of "five modes and ten gears" of the engine 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.
A new type of load-sensitive hydraulic system can realize fine and load-independent manipulation, with excellent maneuverability of small excavators, and high efficiency and energy saving;
The bucket has fast digging speed and strong digging capacity; the bucket speed is fast, and the efficiency is high when working on level ground;
The regeneration function of the working device can supply part of the pressure oil in the small cavity of the cylinder and the pressure oil output by the pump to the large cavity of the cylinder at the same time, so that the recovery speed of the stick is fast and stable, and the work efficiency is improved.
Reliable and durable
Enhanced boom/stick: low failure rate of structural parts;
Reinforced bucket: The wear-prone parts of the bucket (front, two sides and bottom) 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;
Strengthen the "X" walking frame: Strengthen the design of the beam structure with concentrated stress, so that the strength of the cross section is increased by more than 35% compared with the traditional model, and it is more suitable for harsh working conditions and heavy load conditions.
Comfortable and convenient
The maintenance point is 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 arranged 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 engine hood have a large opening angle, which is very convenient for maintenance;
Centralized maintenance points: centralized electrical layout: EECU, fuses, and relays are centrally arranged in the left front cover (adjacent to the air filter), and the layout is also printed on the back of the cover
Figure, maintenance and overhaul * for convenience;
Side-by-side heat dissipation: The engine intercooler, the water diffuser and the hydraulic oil radiator are arranged in triple parallel, with good heat dissipation effect and easy cleaning and maintenance.
