Rotary Drilling Rig

We offer ytr series rotary drilling rig is high efficiency construction drilling rig suitable for the construction of base piles such as bridges, railroads, and building construction. It is featured with high efficiency, power-saving, environmental protection, low machine malfunction rate, and high reliability.
Performance characteristics
1. It is equipped with forehead cylinder, through which the pulley-yoke can automatically fold the mast, so as to reduce labor intensity and improve work efficiency;
2 main winch adopts single-motor reducer drive, which can ensure the stability of strong pulling and rapid lifting, so as to realize high working efficiency of main winch;
3. Rear-placed main winch (patent no.: 200620135077.0) adopts lengthened-type large-diameter winding drum, which realizes a single-layer winding of steel wire rope, greatly improving the service life of steel wire rope;
4. This drill rig uses the most advanced electronic leveling device which can switch between manual operation and automatic operation and is capable of real-time monitoring the mast and carrying out automatic adjustment to ensure the mast is always in the vertical state during construction operation, and this can effectively ensure the pile-hole verticality meets the requirement of the engineering
