SWi5TE TOOL FUNCTION
HYDRAULIC TOOL OPERATION
The SWi5TE Spreading Wedge uses a hydraulic cylinder to
advance the wedge and spread the jaws. The hydraulic
pressure is applied using an external hand pump, enabling
accurate control of the force applied.
HAND PUMP OPERATION
Consult the Instruction Manual for the Equalizer HP Hand-
Pump.
ACTUATING THE SWi5TE
Follow the SWi Spreading Wedge Tool Operation
instructions, using the following instructions to actuate
the SWi5TE tool in particular:
When the Hand-Pump release valve is closed, pumping
the Hand-Pump handle will advance the cylinder and
spread the jaws.
When using multiple tools, ensure that the spread of all
tools correspond to keep the spreading force balanced.
Equalizer manufactures a twin-port hand pump which can
be used to actuate two tools simultaneously.
RETRACTING THE SWi5TE
Opening the release valve 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.
AIR-LOCK RELIEF
If full pressure is not achieved an air-lock may be present
in the hydraulic system. The following procedure can be
executed to relieve any air-locks.
Connect the hand pump to the tool with the hydraulic
hose. Close the release valve on the pump, and prime the
pump until the hydraulic cylinder is fully extended and a
small pressure is achieved.

SPREADING WEDGE
The SWi5TE Spreading Wedge uses an external hydraulic
pump to drive the cylinder to advance the wedge and
spread the jaws.

SWi5TE TOOL CAPABILITIES
SPREADING FORCE
With 700 bar (10 000 psi) of hydraulic pressure applied,
the tool can apply 6.3 T (63 kN) spreading force on the
1st step, up to 7.7 T (77 kN) spreading force on the 4th
step.
SPREADING GAP (SEE SECTION 3.9)
Using only the 1st step, the tool can spread from 4.0 mm
to 29 mm (0.16” - 1.14”).
Using all 4 steps, but without the stepped blocks, the tool
can spread from 4 mm to 79 mm (0.16” - 3.1”).
Using both steps on the stepped blocks, the tool can
spread 56 mm – 101 mm (2.2” - 4”).
