Casing Oscillators
Casing oscillators install and extract casing in challenging ground conditions. Working together with drilling equipment, oscillators facilitate simultaneous drilling and casing advancement. This process offers immediate support preventing shaft collapse and can effectively prevent groundwater intrusion.
Oscillators twist back and forth using oscillating force, as opposed to vertical force, to install casing into the ground. The twisting motion enables the oscillator to cut through obstructions and dense layers more efficiently.
Oscillators are ideally suited for:
Caving conditions, such as loose sands and gravelly soil
Dense strata and fractured rock
Mud and muck
Drilling next to existing structures
Since casing oscillators do not rely on hammering or vibration to install casing, they can reduce the impact on surrounding areas. This is critical when drilling in sensitive areas or near existing structures.
Types of Oscillators
Drill Mount
Drill mount casing oscillators are ideal for projects with a smaller footprint, but still require the power and precision that an oscillator provides.
Available in five configurations ranging from 1000mm (3.3ft) to 2500mm (8.2 ft).
Can install casing ranging from 610mm (2ft) up to 2,500mm (8.2ft).
Torque ranging from 86 ton.m to 539 ton.m.
Reducing adapter is available up to to 1,000mm below the original diameter.
Crane Mount
Crane mount oscillators offer more power than drill mount and can install larger diameters of casing.
Available in five configurations ranging from 2,000mm (6.6 ft) to 4,000mm (13.1 ft).
Can install casing from 1,000mm to 4,000mm diameter.
Torque ranging from 451 ton.m to 2,161 ton.m.
Reducing adapter - up to to 1,000mm below the original diameter.
Heavy Duty (Crane)
The heavy duty oscillator offers more torque and lifting force than the general model.
Available in five configurations ranging from 2,000mm (6.6 ft) to 4,268mm (13.1 ft).
It can install casing from 1,000mm to 4,268mm.
Torque ranging from 721 ton.m to 2,513 ton.m.
Reducing adapter available up to to 1,000mm below the original diameter.
