The manufacturer introduces the synchronization jack (the various structures of Jack are self-protective). When we use the conventional hydraulic jack, we must pay attention to grasp the various structures and control all aspects. In fact, the various structures of the synchronization jack The self-protection is very powerful. Each structure of the synchronous jack can achieve a good self-protection effect, which is embodied as follows.
The high-strength thickened cylinder can avoid cylinder expansion. Chrome plated ) (Chromium) The bottom of the piston rod and the guide sleeve are welded with copper to prevent the pulling of the cylinder and the piston rod. The jack does not need to replace the oil seal to achieve a longer life. The overflow valve will not damage the jack when the connector and tubing are blocked. It can also prevent sudden over-pressure and damage the cylinder. The pressure-retaining valve effectively guarantees safety.
The special structure has multiple protections for the conventional hydraulic jack, and the unbalanced load that can withstand up to 5 of the rated tonnage of the hydraulic cylinder %. In the construction of large-scale projects, the humanized design makes the operation and control easier. It can also prevent the synchronous jack from being damaged by sudden excess pressure. The pressure-retaining valve effectively guarantees safety. The special structure is suitable for the hydraulic jack.
It has multiple protection functions, and the unbalanced load that can withstand is 5% of the rated tonnage of the hydraulic cylinder. In the construction of large projects, the humanized design makes the operation and control easier.
Jacks are classified according to structural characteristics and other categories. According to structural characteristics, they can be divided into three types: rack jacks, screw (mechanical) jacks and hydraulic (hydraulic) jacks. Rack jack: The rack is driven to lift heavy objects by manpower through (tōng guò) levers and gears (Gear). The lifting capacity is generally no more than 20 tons, and it can support heavy objects for a long time. It is mainly used in places where operating conditions are inconvenient or where the lower claws need to be used to lift heavy objects, such as railway lifting operations.
