Hydraulic spreader GYKZ-32～51/640-B
Working pressure MPa
Maximum expansion force KN
Maximum expansion distance mm
Double pipe single connector (with pressure)
In the event of fire, traffic accidents, earthquakes, etc., the product can quickly and effectively expand metal or
non-metallic structures such as steel railings, cars, train cars, etc. to rescue victims trapped in a restricted
environment or to be in danger. The victim in the environment achieves the purpose of ambulance or disaster relief.
It is a necessary rescue tool for firefighting, transportation, industrial and mining enterprises and other disaster
The hydraulic dilator is used with a power source (motorized pump, manual pump). Made of aerospace high-strength
lightweight alloy, it has light weight and large expansion force. The superior self-expanding performance ratio
(self-weight/expansion force) perfectly combines the working ability with the adaptability of Asian human body.
• The prefabricated holes in the expansion head can be equipped with a chain for traction.
• Bilateral anti-slip teeth ensure that the object can be gripped tightly during expansion and clamping operations.
• The UL handle facilitates the operator's left and right hand operating habits.
• Combination of two-way hydraulic lock and automatic reset control valve, which can meet the unexpected situation
during the expansion process and ensure the safety of the operator.
1) Take out the hydraulic spreader and connect the dilator to the power source (motorized hydraulic pump or manual
2) Control the opening and closing of the dilator wall by rotating the reversing handle to achieve the purpose of
Reversing handle: Rotate left and right by hand during operation to open or close the dilator. When the handle is
released, the handle automatically returns to the middle position, and the dilator stops working and plays a self-
3) When the hydraulic spreader is used, the pressure inside the machine should be removed and adjusted to the micro-
tension state of the knife edge.
4) After use, check each part of the dilator to ensure that it is stored intact.
1) In order to avoid injury, the dilator must be used by professionally trained personnel.
2) In addition to the operating instructions, it is also possible to formulate some feasible safety operation
regulations as needed, and rules and regulations to protect the surrounding environment and enforce them, supervise
and command users to perform. These rules and regulations include wearing safety clothing, helmets, goggles,
protective gloves, and the like.
3), without the official approval of the supplier, do not make any modifications, additions or changes, so as not to
affect the operation safety.
4), the ultra-high pressure hose within the service life, even if no unsafe phenomenon is found, it is recommended to
replace it once every 5 years.
5) Insist on regular inspections and check whether the work of each component is normal every six months without
6) When the working environment is in danger of explosion, mechanical power pump should not be used as the power
source. Manual pump should be used as the power source.
