FAQs

Q 1: In the process of mining operations, how to diagnose the problem if the blade has attitude deviation and the classification accuracy decreases?

A: ① Calibrate the position/angle sensors (error margin must be ≤ 0.08 °) and update the attitude compensation algorithm via the XCMG Cloud Platform; ② inspect the backlash in the dual-worm slewing drive (if exceeding 0.2 mm, adjustment or replacement is required); ③ check the pressure of hydraulic system (standard: 38 MPa), remove any impurities from the main spool, and verify the parameters of the load adaptive system.

Q 2: In high dust environment, if the engine frequently triggers alarms, the power output will drop obviously. What is the possible reason?

A: ① Remove the five-stage air filtration system; Clean the primary filter and the oil-bath filter components, and replace the fine filter, nano-filter, and activated carbon filter elements (these should be replaced periodically every 2,000 hours); ② inspect the turbocharger intake duct for dust accumulation and purge it using a high-pressure air gun; ③ check the fuel filter elements for clogging (all three stages of the filtration system must be replaced simultaneously) and verify the atomization performance of the fuel injectors.

Q 3: If the hydraulic system fails to respond after a cold start and the blade can not be operated, how should this be resolved?

A: ① Start the five-stage preheating function (including engine, hydraulic oil, fuel oil, hydraulic system and cab) and wait for 25 minutes until the temperature of hydraulic oil reaches ≥ 25℃; ② inspect the hydraulic lock valve spool (if it is stuck due to low temperatures, disassemble it and replace the seals with low-temperature-resistant perfluoroelastomer seals); ③ vent the air from the hydraulic system (by repeatedly raising and lowering the blade to vent the trapped air), and verify whether the viscosity of hydraulic oil meets the required specifications.

Q 4: In hard rock mining, if the cutting edge of the blade wears too fast, it will continue to be damaged quickly even after replacement. What are the potential problem?

A: ① Use NM 600 wear-resistant blade (characterized by hard cutting edge of tungsten carbide); Ensure the installation gap is ≤ 0.1 mm and securely tighten all anti-loosening bolts; ② adjust the working angle (to avoid direct vertical impact between the blade and hard rock); ③ activate the blade’s automatic obstacle-bypassing function to minimize impact from rocks, and inspect the four-link swing frame for any signs of deformation.
