110m Max Depth Rotary Drilling Rigs High Stability Large Pile Diameter
TR Series rotary drilling rigs are new design with advanced technology composed of advantages based on Caterpillar undercarriage, which are the most versatile and used for deep foundation, such as construction of railway, highway, bridge and skyscraper, Max depths of piling can reach more than 120m and Max diameter can reach 3000mm .
The TR460F rotary drilling rig has an operating weight of approx138 ton. It is suited for:
1. Rotary drilling
2. Drilling cased boreholes(installation of casing by rotary drive)
TR460Frotary drilling rig is widely used in the field of piling construction and currently most of our customers prefer to choose for construction of cross-sea or cross-river bridges.TR460Fdrilling rig has the characteristics of high stability,large pile diameter&depth and convenient transport.
On september,2013, the TR460F was used successful on a project at panjin china, reached 3m diameter and 110m depth of piles.
