I. Introduction to Lucas, Germany
1948 Germany Lucas (Lukas) to begin production of hydraulic equipment, 1962 to 1972, Germany Lucas (Lukas) is a German installation of various types of train derailment device in recovery and rescue technology research; the years 1990 -1993 The factory moved into Erlangen, Germany, and the company officially changed its name to LUKAS Hydraulic Equipment Co., Ltd.
The hydraulic equipment produced by Lukas in Germany has a certain reputation throughout the world.
 Second, SC757E2 hydraulic expansion clamp
SC757E2 Hydraulic Expansion Pliers Features: Large, lightweight.
1 , SC757E2 hydraulic expansion clamp has a stronger extrusion bite force, so that the real professional rescue personnel can complete the rescue work more quickly and successfully.
2. As a major improvement, the SC757E2 hydraulic expansion clamp is only 16.2kg , and its performance is 13% stronger than the previous generation SP310 . The SP555 has another major improvement, with a powerful "shark tooth" expansion head that can be used in a variety of hazardous situations. The compression plate directly built into the expansion arm makes the SP 555 expander more powerful.
3. In short: Using this expander, you can easily complete any rescue situation.
Third, the composition of components
Fourth, technical parameters

V. Instructions
( 1 ) Test run
The device must be vented after repair and before initial start-up:
- Connect the device to the hydraulic pump.
- Open and close the expansion arm of the dilator completely twice, at least with no load.
( 2 ) Exhaust process
We recommend that the position of the hydraulic source be higher than that of the rescue tool during the exhaust process. Relief tool's recommended venting steps:
1 ) Expanding arm up, open and close completely
2 ) The expansion arm is downward and opens and closes completely
3 ) The expansion arm opens up and closes completely
4 ) Completely open and close the expansion arm downwards
( 3 ) Check the power plant
1 ) Before each start of the hydraulic power source, ensure that the pneumatic valve is in the pressure relief state.
2 ) Before connecting the quick-connect interface, the pneumatic valve of the hydraulic device should be set to pressure relief.
3 ) If a single port is used, it can be connected when the hose is pressurized.
( 4 ) Operate the star-shaped manual valve
1 ) Turn on the device
Turn the handle clockwise (in the direction of the symbol) and keep it there.
2 ) Turn off the device
Turn the handle counterclockwise (in the direction of the symbol) and keep it in this position.
3 ) Non-return function:
Release the handle and the star-shaped manual valve automatically returns to neutral to fully ensure the load support function.
( 5 ) Expansive operation instructions
1 ) Safety instructions
The position of the obstacle must be firm before the rescue operation. Make sure that obstacles are properly supported. In different countries, it is also necessary to consider and comply with the safety regulations clearly specified by the state. In Germany, routine safety supervision in compliance with accident safety laws is also necessary.
When working in environments where there is a risk of explosion, the use of electric pumps / motorized pumps is prohibited and manual pumps are used.
When operating rescue equipment, you should wear the following:
- Protective clothing
- helmet with mask or goggles
- Protective gloves
- Ear protection if needed
Before starting rescue equipment, make sure that the operation of rescue equipment and splinters of debris does not harm people who are /are not related to rescue activities . In addition, unnecessary damage to other people's property items must also be avoided.
2 ) Expansion
The expansion head is only used to increase the gap. Full expansion force can be achieved when approximately half the position of the expansion head recess is used. In the expansion of the head after the expansion area can get the maximum strength.
