3.4 SWi20/25TIEX Integral Hydraulic
Spreading Wedge - Feature Explanation
The SWi20/25TIEX Spreading Wedge uses an integral
hydraulic pump to drive the cylinder to advance the
wedge and spread the jaws.
3.4.1 SWi20/25TIEX Tool Capabilities
Spreading Force
With the maximum hydraulic pressure of 700 bar
[10 000 psi] applied, the tool can apply 20 T [200 kN]
spreading force on the 1st step, up to 24 T [240 kN]
spreading force on the 4th step.
Spreading Gap (See Section 4.1)
Using only the 1st step, the tool can spread from 6.0 mm
to 40.0 mm [0.24" - 1.6"].
Using all 4 steps, but without the stepped blocks, the
tool can spread from 6.0 mm to 87.5 mm [0.24" - 3.4"].
Using both steps on the stepped blocks, the tool can
spread 48.5 mm – 103.5 mm [1.9" - 4.1"].
3.4.2 SWi20/25TIEX Tool Function
Hydraulic Tool Operation
Prior to operation, ensure the air-vent in the integral
hand pump is not obstructed. Any obstruction in the air-
vent can cause a vacuum in the system which can limit
the cylinder’s travel.
The SWi20/25TIEX Spreading Wedge uses a hydraulic
cylinder to advance the wedge and spread the jaws. The
hydraulic pressure is applied using the integrated hand
pump, enabling accurate control of the force applied.
The integral hand pump has a control lever which allows
the user to select advance (+) or retract (-).
