Parameters

Parameter

Performance characteristics

◆ The design and technology of rotary drilling rigs have absorbed the advantages of domestic and foreign famous brand products. The main performance parameters have reached and exceeded the level of similar domestic products. The key components are from all international famous brand products, ensuring the reliability of the whole machine.

◆The power head of the rotary drilling rig adopts high speed ratio and Rexroth 200 electronically controlled large displacement three motors, which has large torque and has 4 gears of automatic gear and manual gear. The drilling efficiency is greatly improved.

◆ The rotary drilling rig adopts a detachable crawler chassis, adopts a unique large triangle luffing mechanism, and an extra large drill mast section. The drill mast is designed as a box structure of high-strength material, which improves the stability of the equipment working device and ensures The quality of hole formation during the construction of deep pile holes. The left / right tilt of the mast is divided into two levels of limit, double protection, which can effectively ensure the stability of the equipment.

◆ The rotary drilling rig can be equipped with short auger bits, ordinary drill buckets, sand buckets and other drilling tools. It can be drilled into clay layers, gravel layers, pebble layers and weathered mudstones. Barrel drills and roller cone drills can be used Drilling in the slightly weathered formation.

◆ The rotary drilling rig is suitable for various types of urban transportation construction, railway highway bridges, high-rise buildings and other pile foundation projects.
