What is a large tonnage hydraulic jack? What is its purpose? In fact, the large-tonnage hydraulic jack is a kind of light and small lifting equipment used for lifting heavy objects. The large-tonnage hydraulic jack is mainly driven by manpower and has a large lifting range. Generally, the lifting height is within 400 mm. It is widely used in equipment maintenance and installation. . According to the structural characteristics, it can be divided into rack jack, screw jack and hydraulic jack.
A hydraulic jack is a simple lifting device with a small lifting height. Can be divided into mechanical and hydraulic. Mechanical jacks can be divided into rack type and screw type. Because of its small lifting weight and laborious operation, it is generally only used for mechanical maintenance and is not suitable for bridge maintenance. Hydraulic jacks are widely used because of their compact structure, stable work and self-locking function. The disadvantage is that the lifting height is limited and the lifting speed is slow.
It is no stranger to mention large tonnage hydraulic jacks. This kind of equipment is now widely used in various fields, but how much do you know about the most basic selection points of this kind of equipment? Different applications require us to look at different points, some pay more attention to materials, some pay more attention to performance, and so on. Here are the questions you need to consider when choosing a large tonnage hydraulic jack from different aspects.

When choosing a large-tonnage hydraulic jack, the first thing we must consider is the material of the equipment. The main component of the equipment is the hydraulic jack, including the material of the outer cylinder, the material of the inner core (piston rod), and the material of the fixing ring (the guide sleeve). Because the strength is different, the material selected is also different. The material of the hydraulic jack is one of the determining factors in choosing high-quality, large-tonnage hydraulic jacks. The second is the related accessories of the equipment, of which the sealing ring is a very important part of the large-tonnage hydraulic jack. The selected sealing ring is the most basic requirement for a high-quality large-tonnage hydraulic jack.
