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.
Application of the Equipment:
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.
