What are the excellent characteristics of jib cranes

The jib crane is a small and medium-sized lifting equipment developed in recent years. The structure is unique, safe and reliable. It has the characteristics of high efficiency, energy saving, time saving and labor saving, flexibility, etc. It can be operated freely in the three-dimensional space. show its superiority. This product is widely used in different places in various industries.

The working strength of the jib crane is that of a light crane. The lower end of the column is fixed on the concrete foundation through the anchor bolts, and the jib slewing electric hoist is driven by the cycloidal pin wheel reduction device. Run left and right in a straight line and lift heavy objects. The jib of the crane is a hollow steel structure, which is light in weight, large in span, large in lifting capacity, economical and durable.

Stainless steel self-priming pump is a common pump valve with simple, reliable and durable structure. However, no matter how high-quality products and equipment are, they also need regular maintenance. This can not only avoid some accidents, but also greatly prolong the service life of the pump and valve products. Under normal conditions, the pump generally does not need to be disassembled and maintained frequently. There are several main parts that should be paid attention to when maintaining the pump in general:

1. Rolling bearing: When the bearing is worn to a certain extent after long-term operation, it must be replaced.

2. Front sealing ring and rear sealing ring: When the sealing ring is worn to a certain extent, it must be replaced.

3. Mechanical seal: Generally, the mechanical seal should not be disassembled for inspection under the condition of no leakage. If serious leakage occurs at the leakage port at the lower end of the bearing body, the mechanical seal should be dismantled and inspected. When assembling and disassembling the mechanical seal, it must be handled with care, pay attention to the cleaning of the mating surface, protect the mirror surface of the static ring and the moving ring, and it is strictly forbidden to knock and collide. The main reason for the leakage due to the mechanical seal is that the mirror surface of the friction pair is brushed. The repair method: the end face of the friction pair can be ground to restore the mirror surface. Another reason for mechanical seal product leakage is improper installation of O-rings, or they are caused by aging. In this case, the O-ring needs to be replaced for reassembly.

The jib crane is a new generation of light lifting equipment made to adapt to modern production. It is especially suitable for short-distance, frequent use and intensive lifting operations with high-reliability electric chain hoists. Small area, easy to operate and maintain. Chenghua jib crane has the advantages of novel structure, reasonable, simple, convenient operation, flexible rotation, large working space, etc. It is an energy-saving and efficient material lifting equipment, which can be widely used in factories, mines, workshop production lines, assembly lines and machine tools. And the lifting of heavy objects in warehouses, docks and other occasions.
