Advantages of XCMG Road Construction Machine 27 ton 1.1-1.4m3 Hydraulic Crawler Excavator XE270DK

A. More energy saving and environmental protection

The engine is tailor-made for the excavator and meets the national emission standards; low speed and large torque, low fuel consumption; rear gear room, low noise, low vibration; good altitude adaptability, can use 5000 meters above sea level.

(1) The new generation of Kawasaki key hydraulic components in Japan has higher efficiency, more precise control, and higher quality and reliability, ensuring long-term and reliable strong digging force and excellent operating efficiency;

(2) The new generation of microcomputer control technology accurately controls the injection time and injection volume of the engine, so that the engine always runs in the economic area, ensuring the efficiency and economy of the machine under various operating conditions.

B. More efficient returns

1. Comprehensively optimized new hydraulic system to increase the workload. The new hydraulic main pump has a 12% higher displacement than the previous generation.

2. Powerful walking and digging forces increase the workload.

New walking motor

1) Replace with new model walking motor

2) Traction increased from 194 to 206, an increase of 6%

3. The bucket is increased from 1.2m³ to 1.3m³, increasing the workload.

C. More reliable and durable

1.Four-round and one-belt enhancement upgrades

(1) The shaft diameter of the supporting sprocket is increased by 22%, and the overall related size is increased, which increases the service life of the supporting sprocket.

(1) The thickness of the sprocket is increased, and the overall related size is increased, which increases the service life of the sprocket.

(2) The axle diameter of track rollers increased by 18%, and the overall related size increased, which increased the service life of track rollers.

(3) The tensioning force of the tensioning device is increased by 8%, which effectively prevents crawler teeth and derailment.

(4) The diameter of the guide wheel shaft is increased by 15%, and the overall related size is increased, which improves the guide service life.

(5) The length of the track chain track was increased from 190mm to 203mm, and the height increased by 8.5%, which improved the service life of the track.

2. Chassis enhancement and upgrade

(1) The guide base is provided with reinforcing ribs to prevent the guide base from opening and deforming, thereby improving the durability of the chain rail and the guide wheel.

(2) Extend the inner protrusion of the guide seat to prevent the chain rail from detaching from the guide wheel.

(3) The longitudinal beam bending plate is changed from "mountain" shape to "half-mountain" shape, the thickness of the bending plate is increased by 20%, the internal ribs of the longitudinal beam are strengthened, and the overall strength of the longitudinal beam is improved.

(4) The bent plate of the driving seat is changed from a welded type to an integral type, and the durability of the driving seat is improved.

(5) Strengthen the X beam position, and increase the end face strength by increasing the box beam size, plate thickness and improving the structure.

(6) The cover plate is increased by 2mm, and the rib plate is increased by 6mm.

3. Strengthening and upgrading of working equipment

(1) The root of the front end of the stick adopts a grease filling structure in the middle to improve reliability.

(2) New T-sleeve bearings are used at the joints of the bucket and bucket to improve wear resistance.

(3) Casting type single connecting rod, fully optimizing stress distribution and improving reliability

(4) The suspension type of the front fork of the boom is changed to the bilateral type, which improves the reliability.

(5) Except for the copper sleeve at the root of the boom, the other bearings are oil-hole bearings.

(6) Dovetail design at the root of the boom to reduce stress concentration

(7) A new type of bucket with improved digging performance and improved abrasion resistance. Further enhance the strength of the ear plate and the arc plate, and improve the service life.

4. World-class electrical plug-in components, waterproof level reaches IP56 level, more reliable.

D, smarter control

1. The advanced XCMG excavator intelligent management system adopts CAN bus communication and Internet of Things technology. It integrates the main control system, engine ECM, monitoring system, control panel, GPS cloud control system and on-site diagnostic system to realize the digital sharing of machine information and improve Product intelligence level. Convenient mobile APP micro-service, grasp the position, operation status, working time, fuel consumption and maintenance cycle of the excavator at any time and place.

2. The autonomous controller collects the altitude of the vehicle position and the intake pressure of the engine, automatically determines and determines the database, and prompts the operator to select the plateau mode on the display. Intelligently match the power of the hydraulic pump and the engine, so as to ensure the flow output of the pump, reduce the engine speed ratio, prevent black smoke and car jams, and ensure the efficiency of the excavator.

E, more comfortable and safer

1. The new cab with large field of view, lower noise, more comfortable operating environment, better power air conditioning, better cooling effect, integrated control panel, more comfortable control, 8-inch large display, more stylish.

2. The family-style gold shield-shaped appearance, with stable lines, the whole machine is more atmospheric, the painting of the whole machine is simple and generous, it is highly discerning, full of strength, three-dimensional and impressive.

3. The use of silicone oil clutch fan to achieve on-demand opening control of the cooling fan, reducing indoor noise by 3db (A) on average

4. One-click emergency stop, safety is guaranteed.

F. Convenient maintenance: The engine filter is placed centrally, which makes maintenance convenient and quick.
