The hydraulic shear expander is used with the power source (motorized pump, manual pump) to achieve shear and

expansion functions. When a fire, traffic accident, earthquake or other disaster occurs, the product can quickly

and effectively cut the metal or non-metal structure such as security doors and windows, steel protective railings,

cars, train cars, etc. to rescue victims trapped in a restricted environment. Or rescue the victims in a dangerous

environment for the purpose of ambulance or disaster relief. It is a necessary rescue tool for firefighting,

transportation, industrial and mining enterprises and other disaster relief departments.

1. Take out the hydraulic shear expander and connect it to the power source (motorized pump or manual pump).

2. Control the opening and closing of the hydraulic shear expander by rotating the reversing handle to achieve the

purpose of cutting and expanding.

Reversing handle: Rotate left and right by hand during operation to open or close the hydraulic shear expander. When

the handle is released, the handle automatically returns to the middle position, and the hydraulic shear expander

stops working and plays a self-locking function.

3. When the hydraulic shear expander is used, the pressure inside the shear expander should be removed and adjusted

to the micro-tension state of the knife edge.

4. After use, check the parts of the hydraulic shear expander to ensure that they are stored intact.

1. The maintenance and adjustment of the hydraulic part of the hydraulic shear expander shall be carried out by

professional maintenance personnel in the designated maintenance department.

2. The expansion head should be in reliable contact with the working object to avoid the danger of slipping.

3. When the hydraulic shear expander is doing the expansion work, pay attention to the position of the center of

gravity of the working object, so as to avoid accidental injury caused by the overturning of the working object

during the work.

4. The hydraulic shear expander is used for expansion or shearing. Generally, it should not be used for long-term

support. When the shearing load is working to the required position, appropriate measures should be taken to prevent

the working object from being reset.

5, should always check the hydraulic shear expander, whether the parts are loose, damaged and other abnormal

phenomena, can only work when the normal parts are confirmed.

6. It is not allowed to supply the machine with the hydraulic cylinder only. If absolutely necessary, the hydraulic

shear expander should also be supported at the same time. Do not mechanically squeeze, pull or bend the tubing.
