Hydraulic Casing Oscillator For Drilling Rigs Piling Rigs
Product description
The casing oscillator is a type of full-casing drilling rig. This equipment uses a clamping mechanism to rotate the casing back and forth in both clockwise and counterclockwise directions, reducing the resistance during casing sinking and extraction. The driving of the casing for sinking and extraction operations is achieved through hydraulic cylinders.

Product advantage
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 environment 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 counter weight 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.
1. The casing oscillator is specialized equipment primarily used in construction on unstable strata, such as soft soil layers, gravel layers, and gravelly soil layers. This equipment can hold large-diameter casings up to 3300 mm in diameter, rotating them clockwise or counterclockwise or moving them up and down along the pile axis. Used in combination with grab buckets or augers, it
enables casing-following drilling. It is widely applied in urban metro foundations, deep excavation retaining walls, interlocking
piles for urban redevelopment, pile obstruction removal, and specialized projects such as railway, port, bridge, river, lake,
high-rise building, and hydropower construction.
2. It is suitable for complex formations where slurry cannot effectively stabilize the walls, such as cobbles, silt, quicksand,
fine sand, fractured rock and karst formations, back filled soil, swamps, lakes, and rivers.
