Recently, SANY SR275E electric rotary drilling rig was officially delivered to Qingyi Construction in Taizhou, Zhejiang. This is also the third SANY equipment purchased by the customer. Since the first equipment cooperation ten years ago, SANY pile driver has continued to help Qingyi Construction complete a number of key projects with reliable product performance and efficient service, witnessing the deep friendship between the two parties. The electric equipment delivered this time has injected new momentum into urban construction with green technology and opened a new chapter of development.

The SR275E electric rotary drilling rig delivered this time will be put into the Jiangnan High-end Medical Equipment Industrial Park project after delivery. As a senior enterprise rooted in the pile foundation industry for 30 years, Qingyi Construction has always led the industry with a "steady and steady" style from traditional construction methods to modern construction.

The medical industrial park pile foundation project undertaken by Qingyi Construction faces multiple construction challenges: 1,037 deep piles need to be constructed in a planned land area of 72,000 square meters, and the single pile diameter of 0.7-0.8m and the pile depth of 30-70m put forward strict requirements on equipment performance. In order to ensure green and efficient construction within the tight construction period, the project team conducted multi-dimensional field surveys and technical demonstrations, and finally selected the SANY SR275E electric rotary drilling rig - the equipment is equipped with an industry-leading 275kN·m torque power system, which can penetrate complex strata to achieve precise drilling; its intelligent electronic control technology saves more than 50% energy compared to traditional fuel models. This strategic choice not only demonstrates Qingyi Construction's forward-looking layout of intelligent construction equipment, but also provides key technical guarantees for the project to achieve the engineering goal of "deep pile fast driving, environmental protection and consumption reduction".

SANY SR275E is a fine product created for municipal, housing, venue construction and other projects. The whole machine adopts three power modes: plug-in/hybrid/pure electric, which can meet a variety of working conditions. In addition, it is also equipped with L2 intelligent functions as standard. The main winch, slewing, power head and other key components can achieve full electric operation, the construction efficiency is improved by 30%, and the high-efficiency potential energy recovery technology achieves energy efficiency balance, and the energy consumption cost can be reduced by 50%, which truly realizes efficient construction, energy saving, environmental protection, safety and reliability.

In recent years, SANY pile drivers have taken electric rotary drilling as the core breakthrough point, deeply integrated new energy technologies, and achieved power enhancement and efficient construction through high-density battery packs, intelligent electronic control systems and energy recovery technologies, and built a green construction ecology of "low emissions, low noise and fast response". SANY pile drivers use their technical strength to help the "dual carbon" goals land, create the dual value of "efficient construction + low-carbon transformation" for customers, and lead pile driving machinery into a new era of zero carbon.
