Don't be afraid of hard rock! Sanyi's first double-wheel groove milling machine made its debut in Shenzhen!



recentlyThe first one independently developed by Sany Heavy IndustryDouble-wheel groove milling machineSDC120 completed its first operation in Shenzhen.It has received a lot of attention.

The double-wheel groove milling machine is a hard stratum wall forming equipment used for construction in the field of underground space, and can also be used for square pile construction, mainly used in continuous wall construction of rail transit stations, deep foundation pit support of high-rise buildings, water conservancy and hydropower projects, etc.

In terms of performance parameters, Sany SDC120 body length 12 meters, width 6 meters high 23 meters, the working mass of the whole machine 210 tons,The size is huge. Its maximum working radius is 63 meters, and the main engine power reaches 570kW, withIt has the advantages of high rock breaking efficiency, high slag discharge efficiency, stable micro feed, and intelligent construction.

The Pingshan Station of the Shenzhen-Huizhou Intercity Railway, where Sany SDC120 debuted, is a double-island four-line station, with a length of 660 meters and a foundation pit depth of about 28.68~30.88m.The hardness of the rock formation is 90~110Mpa, and the operation is difficult.

The on-site personnel took out the construction record sheet and introduced it while comparing it."From 4:33 p.m. to 5:28 p.m. in less than 1 hour, the milling depth from 2.53 meters to 2.98 meters, from 6:49 to 8:25 p.m., in less than 2 hours, the milling depth from 2.98 meters to 3.82 meters,The comprehensive milling efficiency is 0.5-0.6 m/h, which is not inferior to the imported equipment."

The equipment purchaser, Shenzhen Shenglong Construction Co., Ltd., is an old customer of Sany, and has purchased 2 sets of Sany SR415 rotary drilling drills, and trusts Sany quality very much. Its head said,This is the first time they have purchased domestic double-wheel milling, and "Sany SDC120 has stable performance, sensitive deviation correction, extremely high efficiency, and performance exceeds expectations."
