Four Corner Drill Tower
Four corner drill tower is a space truss composed of 4 truss legs. With a large space inside, it shows good loading capacity and stability. According to uses, four corner drill towers can be divided into straight towers and inclined towers, which are used to drill straight boreholes and inclined boreholes, respectively. It is mainly used as hoisting drill tool of core drilling rig and water well drilling rig and has the features of light weight, high load capacity and ease of installation and use.
1. SGZ23 drill tower is suitable for deep borehole drilling about 1500m.
2. SGX17 and SGX18 drill towers are suitable for straight and inclined borehole drilling about 1000m.
3. SGX13 drill tower is suitable for 75°~90° straight and inclined borehole drilling about 600m.
