Gantry crane is a variant of bridge crane, also known as gantry crane. It is mainly used for the loading and unloading of outdoor cargo yards, stockyards and bulk cargoes. Its metal structure is like a door-shaped frame, and two feet are installed under the bearing main beam, which can walk directly on the track on the ground, and the two ends of the main beam can have outrigger cantilevers.

I have been engaged in lifting machinery for so many years, and I have come into contact with more and more products. For each of the signs and signs above, let's take a look at these FAQs and see what they mean. 1. Definition of hoisting machinery: Electric chain hoists and other hoisting machinery are indispensable equipment for modern industrial production, which are widely used in the lifting, transportation, loading and unloading, installation and personnel transportation of various materials.

In order to ensure the safety and reliability of the crane operation in Dongguan, the crane is equipped with a relatively complete safety device, so as to protect the machine parts or remind the operator to pay attention in the event of an accident, so as to play a role in safety protection. 1. Each relief valve in the hydraulic system: it can suppress the abnormal high pressure in the circuit to prevent damage to the hydraulic oil pump and motor, and prevent it from being overloaded.

Leakage repair protection: Due to the influence of vibration, wear, pressure, temperature and other factors, the static sealing parts of each joint surface often have oil leakage. The traditional treatment method is to disassemble the reducer, replace the sealing gasket or apply sealant, but it is time-consuming and labor-intensive, and it is difficult to ensure the sealing effect, and leakage will occur again during operation.

According to the structure of the door frame: it is divided into gantry crane, cantilever gantry crane, and gantry crane; 1. Full gantry crane: the main beam has no overhang, and the trolley is carried out within the main span. 2. Semi-gantry crane: The outrigger has a height difference, which can be determined according to the civil engineering requirements of the site. Cantilever gantry crane; 1. Double cantilever gantry crane: the most common structural form, the force of the structure and the effective use of the site area are reasonable.

According to the Chinese national standard GB/T20776-2006 "Classification of Lifting Machinery", lifting machinery is divided into five categories according to their functions and structural characteristics: light and small lifting equipment, cranes, lifts, working platforms, and mechanical parking equipment. According to the classification of the use of the industry, cranes can be divided into industrial and mining cranes, port machinery, special ship cranes,
