Sunward SWDTH100H Large diameter down-the-hole hammer drill

▲ Super powerful power head

① The power head has the functions of side shift and forward tilt.，Use the auxiliary winch to cooperate，Self-installable drill pipe and casing，Save the cost of equipping auxiliary equipment。

② Through the double damping design，Reducing the influence of vibration on power head and main machine in Dth hammer construction。

③ The connection between the main shaft of the power head and the drill rod is equipped with a transition joint as a vulnerable part.，And is convenient to replace，Two kinds of transition joints can be selected.，O as to install the drill rods with different connection modes.。

④ Power head multiple seal，Effectively prevent sediment from entering the gear box，Protect seals from damage。

⑤ Independent oil way lubrication of reducer，Ensure that the lubricating oil is clean，Prolong the service life of the reducer。

▲Special chassis

① Transportation width of the whole machine≤3100，Transport height≤3400mm，Meet the requirements of highway transportation，And that transportation cost is reduce；Working width 4200mm，And that stability of the whole machine is good，360 can be achieved°Stable operation in all directions。

② The main and auxiliary winches are arranged on the platform.，The rotary inertia of the upper part of the platform and the overturning moment of the working device are effectively reduced，Ensure the stability of the whole machine，Liminate that problem that the machine is easy to generate in the process of rotation and travel due to the adoption of a universal chassis of the whole machine,“Nod”Phenomena and even rollover accidents during construction。

③ The rear part of the platform is equipped with stabilizer leg，Machine is as stable as Mount Tai in Dth hammer construction。

▲High strength mast

① The lower end of the mast is provided with a hydraulic telescopic outrigger，Can meet that requirement of the down-the-hole hammer method，But also can facilitate that telescopic operation and the maintenance operation of the crawl.。

② Specifically forDTHReinforced mast of high strength material designed for Dth hammer construction，Structural strength increased by 20%Above。Drill mast with large section、Strong bending and torsion resistance，Ensure that the drilling mast is not bent during heavy load construction、Do not break。

▲Main winch

① Large tension of single rope of main winch，The lifting speed is fast。

② According to different formation conditions and hole depth requirements，Through different ways of roping，Provide different lifting force and lifting speed，Meet the needs of efficient construction。

③ Adjust the hoisting force of the winch according to the weight of the drill pipe during operation，Uarantee the most suitable pressing force required for the operation of the down-the-hole hammer。

▲Gripper

The gripper is mounted on the leg tube.，Can move together with the outrigger tub，Low to the ground，And that operation is convenient。 Capable of clamping drill pipe and casing。

▲Dust cover

① Two-section telescopic dust cover：A slag discharge hose externally connected through the slag discharge port，Lead the drilling debris to a suitable place on the ground，It is especially suitable for construction sites with high environmental protection requirements.，The drilling mud shall be led to the designated area。

② Umbrella type dust cover：Two small winches are used to lift and lower the conveying canvas tube.，Lead the sludge to the ground。Length of casing does not affect slag discharge，Can meet the construction needs of narrow places。

▲Pressurized system

Apply pressure to the power head during spudding，O as to meet the requirement of rapid drilling.。When the power head is lifted，Pressurized float，Perfect synchronous lifting with the main winch。

▲Water and gas system

① Equipped with Dth hammer lubrication system， The lubrication switch of the Dth hammer and the amount of lubricating oil can be controlled in the cab。

② Equipped with water pump system， Used for slag discharge during construction、Rinse、Cooling、Dust reduction, etc。

③ The air intake and air pressure of the Dth hammer can be adjusted in the cab。

▲Safety precautions

Safety guarantee is fully considered for Sunward intelligent large-diameter down-the-hole hammer drill，Make you feel at ease in the construction process.。

▲Handle self-locking function

Proprietary electromagnetic locking handle，Handle positioning with one key，Get rid of heavy physical labor.。
