9 Working Equipment Optional Cab Manifold working equipments are supplied to meet special requirement of customers. Operate comfortably the best cab would improve productivity greatly. (SANY cab for example) Common construction methods are as follows: Kelly bar with drilling tools, casing installation with rotary drive, Continuous Flight Auger drilling, drilling with casing oscillator, etc. Construction technologies include dry drilling, slurry support drilling, whole-course-casing drilling, wall building drilling, etc. Drilling with casing oscillator (Kelly system) Greater embedding pressure can be achieved by casing oscillator instead of Casing Drive Adapter, casing can be embedded even in hard layer. Casing oscillator owns such merits as strong adaptability to geology, high quality of completed pile, low noise, no mud contamination, slight influence to former foundation, easy to control, low cost, etc. It owns advantages in following geological conditions: instable layer, underground slip layer, underground river, strata, old pile, erratic boulder, quicksand, foundation of emergency and temporary building. (see SRT150 brochure) Casing installation with rotary drive (Kelly system) This method has solved problems such as large construction for manual casing embedding, need for auxiliary equipment as excavator, potential collapse of drilling embedded hole and the holecollapse during drilling. It gains obvious advantages in drilling in backfill soil layer, shallow sand pebbles layer and karst cave limestone layer. The powerful rotary drilling rig of SANY-series is capable of installing and extracting casing without the assistance of casing oscillator. Installing casing with Casing Drive Adapter ensure verticality and avoid collapse. Drilling in and installing casing can carry out simultaneously to improve efficiency. 600/800/1000/1200/1500mm 340bar 2180kN.m 500mm 2100kN 13 SANY SR150M/200M/250M/280M Rotary Drilling Rig with CFA System 20t 2200kN 261mm 630mm 21t 4350mm 2730mm 1810mm 2 /2 7 /3 3 /3 11 / psi lbf.ft lbf 18sh.ton lbf sh.ton Note: SANY Casing Oscillator is suitable for SR200C and heavier rig.
