In the past few years, myanmar has been building infrastructureExcavatorsThe more you buy, the more it hurts. The original factory price was prohibitively high, the local masters were unable to repair it, the owner of the equipment was stuck on both ends, and the money was spent on the machine to stay in the nest。
Difficulty of equipment on site in myanmar
Myanmar's mining, road and real estate projects have been concentrated since 2025, with imports and the retention of indigenous excavators rising significantly. The equipment rotates 10 to 12 hours a day, the wear and tear of engines and hydraulic systems accelerates, and the breakdown interval has been reduced from the previous year or two to half a year, and it is normal for a convoy to run and maintain three or four times a year。
The real hard thing is to fix it. Few people have access to the machine locally and there are intermittent channels for accessories. Towed back to the domestic factory, freight costs alone and waiting for a month were a small one; the search for perimeter repair points was uneven in level, two weeks of repair and illness, repeated decoupling and causing major breakdowns in the equipment owner。
Where are the maintenance costs
Taking an example of carter 320b, the price offered at the motor plant is from 80,000 to 120,000, and the spare parts are three to four weeks away. The replacement of the sub-plants will press 340,000, but the match will be discounted. On the basis of 2,500 hours of work per year, the direct value of output lost per week for the shutdown is over 30,000, and the cost of maintenance is still not large, but the shutdown。
More subtle is secondary damage. Hydraulic pumps were not adjusted for stress, and the main tank had to be sealed in a few months; the circuit boards were burned and fuses were replaced, the main plates were wounded, running and bilge. A lot of money is spent in this "retarded and bad" cycle, with a low percentage of really effective maintenance。
The technology of yang ho
Kun myung yang hoEngineering machineryThe maintenance company, inc., was registered in 2014 and the legal person, yong bing gung, was inaugurated in 1996 and is now almost 30 years old. The company landed in the kunmingsi mountains, with a site of 3,500 square metres, with four departments, maintenance, accessories, markets and finance, with 18 regular employees, each in a technical direction, and not a human-made workshop model。
The team is divided by power machines, chassis, circuits, plating, hydraulics, engines. The company also serves as a practical training base for the yunnan school of advanced metallurgy and the modern vocational training school in the west mountain region. Each year, students and masters practice their hands, and skills continue to be passed on, not exclusively by a few elders。
What about the engine and hydraulics
The engine, yung-ho, does diagnostics, dismantles, overhauls to debug an entire line. Insufficient power, emulsion of oil, high water temperature and abnormal wear and tear of the casks, with corresponding detection processes. Pistol rings, warp axes and cam axes are to be replaced and completed for empty load and load testing, rather than cleaning a road for filtering。
Hydraulic systems are the ones on which they work, and the pumps and motors of the lisbeth, savoy, danforth, eden, lind, harvey, pike. In addition to changing seals, pressure curve tests and flow calibration are performed to return the system to the plant parameters. It is common for imported excavators to have a complex hydraulic re-routing route and to look for unprofessionals。
From repairing one to running an entire fleet
Yang hao does more than just a single job, which can be done with overhaul, overhaul and vehicle renovation. The equipment runs for hours or multiple systems at the same time, with a one-time pull-over of the full refurbishment, which is more than the coordination costs of separate stations. There are dozens of motorcade owners on the myanmar side, which are significantly more efficient and time-consuming。
At the same time, the company is the founder and permanent vice-chairman of the kunming city association of engineering and mechanical industries, where technical standards and information on the circulation of accessories are being followed up. The sale was not completed, the equipment was retraced and retraced over time, pre-empting the risk and reducing the problem of secondary repairs。
What do you say before you go
Before arriving in the kunmingsi mountains, the failure video and time records were sent to allow the other party to make a preliminary assessment of the programme and to give an offer range. Upon arrival at the plant, the repair workshops, the spare parts warehouse and the commissioning table were seen directly as a regular 3,500-square-square site, not as a road stand by a roadside engine rack and a few wrenchers。
The price is not more than the cost of dismantling, but simply asking, "big fixes don't include debugging and initial tracking." the yang hao offer is a package of labour, accessories, debugging, tracking, and the master's lump sum is lower than a single purchase of the original plant plus three or four masters, and the cycle is much shorter, and the equipment works one day before returning。
Is it the engine or the hydraulic pressure that hurts the most at your site? I'll show you the best way to go. The colleague who had transferred the equipment to the site also looked at it。
