GM-20A Engineering Drilling Machine - Product Introduction
The GM-20A engineering drilling rig is an improved tower crane integrated large-diameter lightweight engineering drilling rig based on the GM-20 drilling rig in our factory.
This machine combines the characteristics of three types of drilling rigs: rotary table, power head, and spindle type. It has the advantages of high drilling efficiency, high drilling torque, high drilling accuracy, small oversize coefficient, wide rotation speed, hydraulic pressure and pressure reduction drilling, fast and complete oil cylinder lifting and lowering tower. After moving, the hole opening is open, and it can directly move up and down 2.0 meters. It can directly lower the steel cage. The auxiliary winch has strong lifting ability, centralized control, walking step by step, and convenient hole positioning. The forward and reverse circulation drilling technology can be used to drill in Quaternary gravel bearing formations and hard formations. Suitable for drilling large diameter foundation pile holes in bridges, highways, high-rise buildings, and other areas.
GM-20A Engineering Drilling Machine - Technical Features
1. Reasonable structure, small volume, and light weight.
2. High torque, wide speed range, strong process applicability, and wide range of applications.
3. The rotary device is fixed, with high drilling accuracy and small pile hole diameter coefficient.
4. The use of a pressure beam oil cylinder for direct pressurization results in high drilling efficiency and large lifting capacity.
5. The movement stroke of the rack is 1500mm, and the hole opening is open, making it easy to drill in and out.
6. Adopting oil cylinder lifting and landing tower, the drilling tower has fast and safe lifting and landing, and convenient management and maintenance.
7. Equipped with a walking mechanism, the construction operation is convenient and fast for drilling.
8. The drilling rig has good stability, flexible operation, and safety.
