CASING OSCILLATOR

Oscillator is in use for insertion and retraction of casing using ALL CASING (BENOTO) method for foundation work of buildings and bridges. Insert 1 to 3 meter diameter casing by oscillating with hydraulic cylinders, simultaneously remove soil and gravel from inside of the casing using hammer grabs and/or chisels for breaking rocks. Once the casing reached predetermined depth, the reinforced bar cage is inserted, the concrete is filled through tremie pipe, the casing is retracted, and thus a cast-in-place concrete pile is constructed under the ground.

1. PRODUCT FEATURES

  • By replacing the adapter, 1,000 to 2,500mm diameter pile can be constructed.
  • Adopting 5-link clamping collar prevents casing deformation by distributed clamping force.
  • The verticality can be easily controlled when inserting casing.
  • Stability and durability are accomplished by optimized computer aided engineering and adoption of high-strength material.
  • Advanced hydraulic system and remote control system guarantee the safety of the machine in operation.
