Hydraulic System Casing Oscillator for 600-1500 mm Diameter Casing Pipe High Efficiency
(1) Low purchase and transport costs for the shared utilization of rig pump instead of special pump truck.
(2) Low operation cost for the sharing of output power of rotary drilling rig, energy saving and environmental friendly.
(3) Ultra-large pull/push force up to 210t is supplied by lifting cylinder and the large can be achieved with added counter-weight to speed up construction.
(4) Dismountable counterweight from 4 to 10t as required.
(5) Reduction in transport cost for the counterweight is made of cast-in-place concrete.
(6) Work stably-combined action of counterweight frame and ground anchor fix the bottom of oscillator to the ground firmly and reduce the reaction torque generated by oscillator to rig.
(7) High working efficiency for the automatic casing oscillation after 3-5m casing-in.
(8) The distance between oscillator and rig can be adjusted conveniently due to bolt connections.
(9) Added anti-torsion pin of clamping collar to ensure 100% torque transfer to casing.
(10) 0.6-1.5m casing diameter with different clamping collar to meet customers’ needs.

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 control, low cost, etc. It owns advantages in following geological conditions: instable layer, underground slip layer, underground river, rock formation, old pile, erratic boulder, quicksand, foundation of emergency and temporary building.
Application Range: Railway base, secant pile wall of deep foundation, pile extracting and clearance of the scrap pile for city reconstruction; Construction for port, bridge, river, lake, tower, hydropower, bored concrete pile, special purpose of bore pile. Casing construction suits for inner-city construction, it's also applied to around existing buildings; Batter pile is also applicable.
