Chassi altamente estável da perfuratriz rotativa JINT SD25

Strong power and adaptability to geological formations

250kN · m torque+250kN compression, suitable for clay, sand layers, and strongly weathered rocks, with outstanding rock penetration ability.
Cummins QSL9 engine+high flow hydraulic system, fast power response, high efficiency of soil perforation.
The power head speed can be adjusted from 8-30rpm, making it faster to drive and unload soil, and more stable under complex working conditions.

Reliable structure and high construction accuracy

The large triangular mast and four-bar linkage structure are resistant to torsion and bending, ensuring overall stability and preventing deep piles from swaying.
The solid guide rail undergoes heat treatment, and the straightness of the pressure stroke is controlled within 0.5mm, resulting in high verticality of the drilled hole.
Integrated counterweight and reinforced chassis provide strong durability under harsh working conditions.

Multi functional adaptation, flexible construction

Multiple construction methods such as rotary drilling, down the hole hammer, and forward and reverse circulation can be switched, making one machine versatile.
Dual mode of friction rod/machine lock rod, covering a depth of 57-64m, meeting the requirements of medium and deep piles.
It can be equipped with various drill bits such as short spiral, sand dredging, and rock entry, and is suitable for different geological formations.

Transport friendly, low transfer cost

Three section foldable mast with low transportation height, compliant for board truck transportation, and no need to dismantle the mast.
Scalable chassis+wide rail design, flexible transition, strong adaptability to small and medium-sized field operations.
