I am from Heishan Mining Area, Dulan County, Qinghai Province. I purchased a 120kw generator set from Weifang Heavy Machinery Co., Ltd. on July 14, 2012. It arrived on August 10, 2012. At that time, the test run was not possible. After communicating with the manufacturer many times, it can temporarily work after 3 days of debugging. After 4 days of work, the generator stalled and could not work. After many communications, the company refused to provide after-sales service, causing a 15-day shutdown and a loss of more than 200,000 yuan. After negotiation, After many efforts, Manager Ji sent an engineer from Lanzhou Electrical Machinery Factory to repair on the 11th. The engineer said that the cause was unknown and could not be repaired, so he only made emergency temporary work. To this day, Weifang Heavy Machinery Co., Ltd. personnel are still unwilling to come forward to solve the problem. It can be seen that There is no after-sales service at all. Although its quality is a German joint venture, I cannot praise it. Please choose carefully and don’t be deceived!
