The urban renewal project in Shijiaotou Industrial Zone, Guanlan, Shenzhen is underway, with 13 Sany rotary drilling rigs densely deployed, led by the SR485. Sany's "4-series" large rotary drilling rigs, with their powerful construction capability, outstanding rock-drilling performance, and stable continuous output, are helping to accelerate the "Guancheng Phase I Urban Renewal" project in Guanhu Subdistrict, Guanlan.

The site manager said that the project has a tight schedule, and rotary drilling rigs, as the "advance force" of project construction, directly affect the project progress. On the premise of ensuring construction quality, efficiency is particularly important, and all equipment must meet high requirements, so Sany brand equipment was chosen. The Sany rotary drilling rigs at the project site include 4 SR405H, 4 SR415, 3 SR445, and 2 SR485.

Sany's "4-series rotary drilling rigs" feature large-displacement, high-power engines with strong power, energy efficiency, and environmental friendliness. The advanced power control system fully leverages pump and valve performance, resulting in high actuator efficiency; large travel traction and strong site adaptability.

At present, the project is in its initial stage, with the main construction work being 25-meter rock drilling in strata of 80 MPa moderately weathered to slightly weathered rock with many fissures. In equipment selection, the goal is optimal performance and maximum efficiency. At the same time, Sany's after-sales service is efficient and timely, providing customers with construction method support and customized roller bits and cutting teeth to ensure the most efficient construction method.

With the support of numerous Sany machines, the Guanlan urban renewal plot project is proceeding in an orderly manner. The project will become another hotspot area after Ocean New City and Guangming Science City. In the future, Guanlan New City will become a benchmark area for smart industries, aiming to build a new smart city integrating smart industries, core R&D and production headquarters, leisure and entertainment, ecological living, and cultural tourism.
