Used XCMG XE305D crawler excavator

Product Introduction

XCMG XE305D excavator adopts Cummins three-stage engine, XCMG proprietary power characteristic curve, low speed and high torque, strong power, fuel economy, and meets the construction needs of 5000m above sea level. Equipped with the Kawasaki hydraulic system imported from Japan, and the hydraulic pipeline upgrade design at the same time reduces the pressure loss of the oil return, improves the combined operation of the front-end working device, improves the handling performance of the whole machine, and comprehensively improves the operating efficiency, coordination and performance of the whole machine. stability. The new control system realizes the reasonable matching of the power characteristics of the engine and the main pump, and improves the power utilization rate and fuel economy.

Product Features

1. For harsh working conditions such as heavy dust, the air intake system is a three-stage filter, and dry or wet air pre-filters can be selected. It is equipped with extended and reinforced chassis system as standard, which has better stability and reliability in mine work. The reinforced four-wheel belt adopts the reinforced four-wheel belt to ensure the service life under harsh working conditions such as mines. Working device: Use finite element analysis to strengthen the key parts of the boom and stick. The root of the front end of the stick is filled with grease in the middle to improve reliability. A new T-shaped sleeve bearing is used at the joint of the stick and bucket to improve wear resistance. Except for the copper sleeve at the root of the boom, other bearings are all oil-cavity bearings. The dovetail design is adopted at the root of the boom to reduce stress concentration. 6000psi standard flanges are used for the oil ports of main hydraulic components such as the central slewing body and hydraulic cylinder, and the high-pressure hose connections to reduce the risk of leakage. Radiator: The radiator adopts high-performance composite fins and new lead-tin welding process, which improves the heat dissipation efficiency, saves energy and reduces noise, and the environmental temperature adaptability is increased to 50 . The anti-loose, anti-vibration and anti-shock design is designed for the oil return pipeline, filter pipeline and hydraulic pipeline of the crushing device, which can better adapt to the crushing working conditions.

2. The advanced XCMG excavator intelligent management system adopts CAN bus communication and Internet of Things technology, integrates the main control system, engine ECM, monitoring system, control panel, GPS cloud control system and on-site diagnosis system, realizes digital sharing of machine information and improves Product intelligence level. The convenient mobile APP micro-service can grasp the location, operation status, working hours, fuel consumption and maintenance cycle of the excavator anytime and anywhere. The autonomous controller collects the altitude of the vehicle 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 speed ratio of the engine, prevent black smoke and brake the car, and ensure the working efficiency of the excavator.

3. The buffer valve group and flow diversion device are developed to reduce the pressure shock of the hydraulic system and improve the control performance of the whole machine. High-performance silicon oil spring shock absorbers and four-point support can effectively isolate specific frequency bands, reduce the impact of the external environment, and improve driving comfort. Brand-new streamlined driving space design, car-level luxury interior, wide vision and more comfortable. Standard silicone oil clutch, fan stepless speed change technology, further energy saving and noise reduction.

4. The oil filter, pilot filter, fuel filter, oil-water separator, and air filter are installed where they can be inspected and replaced on the ground, which is within reach and easy to maintain. Save maintenance time and improve work efficiency. The new oil pocket bearing greatly improves the grease filling cycle: the inner diameter surface of the oil pocket bearing is covered with oil pockets with a depth of 2mm, which are used to store grease and ensure that the grease will not be lost easily. The special cross-section design of the oil hole makes a small amount of lubricating grease come out when the shaft and the bearing rotate relative to each other, forming an oil film on the shaft surface and reducing the amount of wear.
