SWi20/25TI 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 SWi20/25TI 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 (-).
ACTUATING THE SWi20/25TI
Follow the SWi Spreading Wedge Tool Operation
instructions, using the following instructions to actuate
the SWi20/25TI tool in particular:
When advance (+) is selected, pumping the handle will
advance the cylinder and spread the jaws.
RETRACTING THE SWi20/25TI
Selecting retract (-) will depressurise the cylinder and
cause it to retract under the force of its internal spring.
The handle does not need to be pumped to retract the
tool.
When using multiple tools, exercise caution while retracting
to keep the spreading force balanced as the gap is closed.

SWi20/25TI TOOL CAPABILITIES
SPREADING FORCE
With the maximum hydraulic pressure of 700bar
(10,000psi) applied, the tool can apply 20T (200kN)
spreading force on the 1st step, up to 24T (240kN)
spreading force on the 4th step.
SPREADING GAP (SEE SECTION 3.9)
Using only the 1st step, the tool can spread from 6.0mm
to 40.0mm (0.24” - 1.6”).
Using all 4 steps, but without the stepped blocks, the tool
can spread from 6.0mm to 87.5mm (0.24” - 3.4”).
Using both steps on the stepped blocks, the tool can
spread 48.5mm – 103.5mm (1.9” - 4.1”).
