construction piling big hole drilling hammer

Application:

This type of construction pile big hole drilling product is designed and developed by our company in accordance with the characteristics of water wells, building foundation piles and especially for water wells.

Advantages of Big Hole Drilling Product

Adopt advanced rock drilling theory to optimize internal structure and gas distribution size to make hammer device to achieve ideal energy transfer. Therefore, the drilling speed is fast and the air consumption is low.

In this kind of engineering projects, after drill bit breaks, it will be very difficult to salvage, it is specially designed safe and reliable bit anti-falling device.

If you need to strengthen the slag discharge during use, you can replace the check valve of the air regulating hole of different sizes to achieve the goal.

The special thread of the top sub and the drive chuck can be easily disassembled.

Features:

Urban high-rise building construction, high-speed rail, highways,bridges, subway construction, hydroelectric stations, nuclear power plant construction projects will involve the pile foundation project. With the increasing demand for hard rock drilling in these projects, Our company designed Super series hammers and bits specifically for these types of projects is being developed with most fluent engineering experience in large diameter boreholes and ultra-deep boreholes drilling, fully meet the requirements of the pile foundation construction drilling work.
