SWSD2512 CAP (Casced augered pile) system has been developed with independent intellectual property rights and achieved national patent. This system is developed for the execution of big diameter cast-in-situ pile, stell tube pile and other complex piles in any kind of soil. The application with DTH hammer can helps greatly in rocky stratum penetration. SWSD2512 CAP (Casced augered pile) system is a environment friendly drilling rig that features low nosie, no vibration, no bentonite mud compared with traditionl hammering application.
·Double rotary system -Coxial reverse rotation, Anti-reverse force self-balancing; Inner and outer rotary tables can upward and downward separate freely for different kind of drilling application. -Full hydraulic drive, constant power variable, high torque, smooth operation, power-performance.
·CAP (Cased augread pile) application -Outer rotary for casing and inner rotary for augers achieve rigid penetration and good verticality. -Cased augers attached with DTH hammer can greatly helps penetrating the rocky stratum with good efficiency. -Advanced intelligent control technology, CANBUS technology and virtual instrument technology, using highly reliable embedded engineering PLC and true color LCD display, self-developed SUNWARD DESARSR electronic system which features high integration, smooth control, fast and percision. -Convenient for maintenance. -Excavate the piles without the bentonite mud in any kind of soil, also in presence of water table. -Guarantee a deviation from verticality of less than 1-1.5%. -Minimise the jobsite installation plant. -Operate in restricted area. -Reduce the execution time of the pile by using double rotary equipment. -No need of a service crane.
