Introduction

FES’s Hydraulic DTH Rotary Hammer is an innovative hydraulic down-the-hole digging hammer, which can be easily hooked up to a rotary drill rig, and produce combined functions of hammering and rotary drilling. It is designed to drill hard rock with high efficiency and low energy consumption, cutting the overall operation cost by at least 50% in comparison with conventional DTH hammers.

Environment-friendly, fast penetration rates, and high drilling efficiency, this monster DHT rotary hammer is able to drill holes from 39" to 59" (1000mm to 1500mm) in diameter.

Recorded penetration rate:

10 centimeters (4 inches) per minute in 90MPa hard limestone

5 centimeters (2 inches) per minute in 210Mpa fine-grained granite

Features

The highlighted features of this revolutionary solution are as below:

(1) Compact and fuel-saving, only require one separate power pack as power source, thus cutting fuel consumption by up to 75 percent

(2) Increased penetration rate and high drilling efficiency on all types of hard rock, with its special designed high-speed-vibratory drilling bucket (or core barrel)

(3) Easy operation to discharge soil and rock activating slight vibration function of the hammer

(4) Low maintenance and long service life with high-quality materials and innovative design

(5) Low construction noise by cutting rings on rock formation which strikes a much smaller area

(6) No dust generated during operation, the broken rocks will be kept inside the bucket of the rotary hammer to be emptied onto the ground
