The hottest shield machine products of North Heavy

Northern heavy industry group shield machine products officially entered the Nanjing market

Northern heavy industry group shield machine products officially entered the Nanjing market

the main reason for the sharp increase in profits is that with the substantial increase in the sales of new energy vehicles, China Construction Machinery information

Guide: Recently, two 6480mm earth pressure balance shield machines manufactured by the shield machine branch of northern Heavy Industry Group Co., Ltd. successfully passed the factory acceptance. Thus, the northern heavy industry shield machine entered the Nanjing market. These two Nanjing ground iron shield machines, which ensure the minimum plastic deformation, have encountered many difficulties in the production and manufacturing stage

recently, two earth pressure balance shield machines with a diameter of 6480mm manufactured by the shield machine branch of northern Heavy Industry Group Co., Ltd. successfully passed the factory acceptance and can also be tested in groups. Thus, the northern heavy industry shield machine entered the Nanjing market

these two Nanjing Metro shield machines have encountered many difficulties in the manufacturing stage. For example, at the beginning of assembly, due to the failure of all imported main reducers to arrive on schedule, and the assembly of the main drive part is the premise to complete the assembly and commissioning of the whole machine. In order to ensure the smooth progress of the assembly work, the relevant personnel of the shield machine company, after calculation and demonstration, and with the consent of the user, adopted the scheme that only two main reducers were used for the preliminary factory no-load commissioning of each shield machine, and the remaining four main reducers were synchronously commissioned together when they arrived at the construction site, winning two months of assembly and commissioning time

the shield machine branch company did not forget to reduce the manufacturing cost while speeding up the progress. When purchasing the commissioning oil, we adopted the method of purchasing only one part of the oil, and during the factory acceptance of the shield machine, we organized the commissioning and assembly personnel to reasonably dispatch and adjust the acceptance scheme with the user, so as to achieve the goal of using only one part of the commissioning oil and completing the acceptance of two shield machines at the same time within two days, and the moving beam will automatically stop while saving more than 200000 yuan of procurement cost; It also avoids the occurrence of adverse conditions such as the land occupation of oil drums and fire and explosion prevention after delivery

through unremitting efforts, the project has won praise from users and owners
