There are several reasons why the hydraulic rod cannot be pressed down no matter how hard it is:
1. The hydraulic rod is used at the wrong angle. According to the lever principle, if the power arm is too short, the force It is not fully utilized, so the hydraulic lever cannot be pressed down.
2. The hydraulic rod itself is damaged. If there is a problem with the machine itself, it will not work no matter how hard you try.
3. The person using the hydraulic rod is too weak. The weight shown in the picture is 70kg. He may not be able to press it down because he is not strong enough.

Advantages
1. It can be started with load, but electric push rods are very difficult.
2. It has overload protection capability and will not damage the motor and parts.
3. The pushing and pulling force of the same electro-hydraulic actuator can be adjusted wirelessly, so the driving force has a wide range, which is incomparable with electric and gas actuators.
4. When the thrust and speed are the same, the power consumed is only half of that of the electric push rod.
5. This product adopts full hydraulic transmission, which is sensitive in action and stable in operation. It can effectively buffer external impact force. Accurate stroke control cylinders and electric push rods cannot achieve this.
6. The electro-hydraulic push rod adopts a fully enclosed structure integrating mechanics, electricity and hydraulics. The working oil circuit circulates in a pressureless closed steel cylinder. It is small in size, does not leak oil, and is easy to install and maintain. In harsh working environments, it does not absorb dust, does not enter water, does not corrode internally, and has a longer service life than cylinder electric push rods.
7. The investment is small. The cylinder requires an air compressor station, the hydraulic cylinder requires a hydraulic station, and the electro-hydraulic push rod does not require any ancillary equipment.
