4.2. Description of the operation
In order to remove the hook (Pos.-No. 2) the pump lever (Pos.-No. 1) will be pressed
towards the body of the pump so that the hook can be pushed aside and thus releasing the
pump lever.
By actuating the pump lever with the foot the crimping cycle will be initiated. After
continuously actuating the pump lever the pump will switch off automatically when
reaching the max. operating pressure at 700 bar. Reaching this point will be indicated by
an audible „click“. The pump has a double piston which allows a fast approach of the dies
to the cable lug in a low pressure mode. When the compression starts the pump will
automatically switch over to the high pressure mode.
Before terminating the crimping cycle the piston can be manually retracted by actuating
the release lever (Pos.-No. 3) e.g. in case of a handling error.
If a pressure pick up is available the pressure increase can be observed.
4.3 Description of the crimping procedure
A crimping process is characterized by the closing motion of the dies. The cable lug or
connector will be positioned in the stationary half of the crimping die. The piston will push
the moving part of the die towards the compression point.
The crimping process is complete when the dies are completely closed and the maximum
operating pressure is reached. When the max. operating pressure is reached the safety
valve opens and guides the pressure medium (hydraulic oil) back into the reservoir.
Detailed remarks about the assembly of the connecting material can be taken from the
assembly instructions in our catalogue.
5. Remarks with respect to the determined use
The pump must be positioned on an even surface with a max. angle of 15°.
In combination with a 2 m high-pressure hose it is not possible to work in a cable trench.
For this application at least a 3m high-pressure hose is needed.
5.1. Operation of the unit
1.) First you have to select the right dies (Pos.-No. 7) for the intended application. Then
roll out the hose completely and connect the crimping head (Pos.-No. 6) with the high
pressure hose (Pos.-No. 5) via a coupling (Pos.-No. 8). This is done by pluging the
male part of the coupling which is on the hose into the female part of the coupling
mounted on the crimping head until they are securely engaged. Finally the coupling
sleeve is secured with a lock (Pos.-No. 9), a threaded sleeve, to block the retractable
sleeve of the female coupling.
Attention
Don’t actuate the pump without the crimping head.
