400t hollow core hydraulic jack, also known as hydraulic jack, is a jack that uses plunger or hydraulic cylinder as a rigid lifting member. Simple lifting equipment generally only has a lifting mechanism for lifting heavy objects. The 400t hollow core hydraulic jack has simple structure, light weight, easy to carry and easy to move. Commonly used simple lifting equipment includes hydraulic jacks, tackles and hoists. For questions about the brand of hydraulic jacks, specifications and models of hydraulic jacks, you can directly contact us, a professional manufacturer of hydraulic jacks. Product introduction:
400t hollow core hydraulic jack is light and small lifting equipment that use rigid lifting parts as working devices to lift heavy objects in a small stroke through top brackets or bottom claws. Jacks are widely used in heavy vehicles or mobile equipment to support the weight of the equipment and adjust Important hydraulic components of equipment level. Jack is the simplest lifting equipment with small lifting height (less than 1m). The hollow jack we often see uses this principle to achieve force transmission.
  working principle:
There are mechanical jacks and hydraulic jacks. The principles are different. In principle, the most basic principle based on hydraulic transmission is the Pascal principle. That is to say, the pressure of the liquid is the same everywhere. In this way, in a balanced system Among them, the pressure exerted on the smaller piston is smaller, and the pressure exerted on the larger piston is also larger, so that the liquid can be kept still. Therefore, through the transfer of liquid, different pressures on different ends can be obtained, so that a transformation can be achieved. The hydraulic jack that we commonly see uses this principle to achieve force transmission. The mechanical principle of the screw jack is that the handle is pulled back and forth, and the claw is pulled to push the ratchet gap to rotate. The small bevel gear drives the large bevel gear and rotates the lifting screw, so that the lifting sleeve can be raised or lowered to achieve the function of lifting tension. . But it is not as simple as a hydraulic jack.
