Rotary Drilling Rig SR280R Piling Drilling Rig for hot sale

Application

The SR280 excavation drilling machine is more capable. By replacing the working device, the construction of the CFA construction method and the rotary drilling method can be implemented. Optimize, have stronger bending and stress and absorbing vibration capabilities; high power head torque, equipped with unique and efficient lubrication system to ensure normal operations in high temperature environments; with "standard", "low -speed large torque", "high -speed small torque" Three types of drilling models to meet the requirements of various working conditions;

Features

1· One machine is more capable. By replacing the work device, the CFA construction method and the construction of rotary drilling method can be implemented separately.

2· Unique truss -type vibration -resistant mast, using frequency resonance technology to optimize the stability of the system, with stronger bending and pressure and absorption vibration;

3.Dynamic head torque is large, equipped with unique and efficient lubrication system to ensure normal operations in high temperature environments; three types of drilling model: "standard", "low -speed large torque", and "high -speed small torque" to meet the construction requirements of various operating conditions;

4· The unique pulleys set device, realize the main roll up and multiply the drill rod, and the pull -out force is large;

5· The main volume has the function of the bottom of the bottom of the protection and priority control, which can be optional to accelerate the decentralization function;

6· Long spiral drill rod is reliable, rigid, highly abrasion -resistant, and has good sealing; unique double -layer core tube design not only increases the strength of the long spiral drill rod, but also ensures the smoothness of concrete transmission, improves the construction of construction, and improves construction. efficiency;

7· Equipped with a lengthened drill rod, effectively increased the drilling depth without increasing the length of the mast
