SH25H pneumatic impact drilling rig

SH25H hydraulic pneumatic percussion drilling rig is a new type of pile foundation construction equipment based on drilling of bedrock. It combines the technical advantages of rotary drilling rig, downhole hammer and hydraulic continuous wall grab, and the host can easily perform impact. Spinning and long spiral drilling function switching.
Ultra deep hydraulic extrusion drills:

This type of drilling rig is equipped with an ultra-long drill pipe of 3 meters, and its capacity is more than double that of ordinary drilling tools of the same caliber, and the single drilling footage is twice that of ordinary drilling tools, greatly reducing the number of drill rod lifting during construction, and at the same time reducing the Sticks, masts risk. Due to adopting a special method of earth-moving, the door-opening mechanism of the drill is omitted, so that the diameter of the drill bit can be made smaller, and the construction of the small-diameter pile foundation of 600mm-700mm can be satisfied. The drill joint part can be disassembled from the drill bit body and replace the bit bodies with different diameters, which is suitable for all kinds of soft soil layers such as sand layer and silt. CZD impact grab:

CZD impact grapple

The traditional impact grapples are often suspended by steel wire ropes and fall naturally when used. As there are no guiding facilities, they may deviate from the target point or pose a security threat to the surrounding operators. In addition, if there is a problem with the rope, the impact grapple may accidentally fall off. When the CZD impact grapple is difficult to excavate the earth and stone in the case of normal grapple, the inner rack body connecting the impact grapple and the grapple cylinder is released through the hook device, and the inner rack body is used to impinge the bottom of the tank with the gravitation force in the slurry and insert into the hard Earth and stone layers, excavated after crushing.
These gorgeous new products are just a microcosm of the technological innovation of Shanghai Jintai in recent years. Since the current round of macroeconomic policy adjustments, the downstream demand of the construction machinery industry has been weak, which has affected the research and development of new products in the industry. However, Shanghai Jintai “adopts the opposite course”, actively implements new product strategies, conducts in-depth research on the development trend of pile machinery and user needs, and accelerates the development of multi-purpose pile products in order to solve practical construction problems and improve construction efficiency. In addition to the products, SX double-row milling, SC milling and stirring rigs, SP hydraulic drilling rigs, SZ double-power hydraulic multi-function drilling rigs, YKD hydraulic reamers, and other engineering equipment have been introduced to inject new life into the depressed market.
