Product Description

Overview

The YR 525 Hydraulic Drilling Rig is a powerful and efficient solution for medium to large-scale foundation projects. Designed for challenging soil conditions, it offers exceptional drilling performance with a maximum depth of 25 meters. Ideal for applications such as bridge piling, highway construction, high-rise foundations, and wind farm installations, the YR 525 combines advanced engineering with reliable operation.

Powered by a 153 kW Cummins engine, this rig delivers 110 kN·m of rotary torque, ensuring high efficiency and performance even in tough formations. The rig is equipped with a dual winch system—110 kN main and 60 kN auxiliary—providing versatility for lifting and rod handling tasks. The hydraulic system offers a pressure of 35 MPa, while the 3000mm pull-down piston stroke ensures stable, precise drilling operations.

With a transport size of 9500mm × 2200mm × 3300mm and a total weight of 26 tons, the YR 525 combines industrial power with mobility. It is capable of handling up to 1500mm drilling diameters and can drill to depths between 10 and 25 meters, making it an excellent choice for demanding infrastructure projects. The rig is also designed for rugged terrain with a 30% gradeability and a ground clearance of 340mm.

YR 525 comes with factory-direct pricing, military-grade quality control, and dedicated technical support, making it a reliable choice for large-scale foundation drilling.
