Shell type grab bucket: suitable for loading various bulk cargo, minerals, coal, sand and gravel, earthwork, etc. in ports, docks, station freight yards, mines, etc., and also for earthwork excavation, foundation and ditch excavation, highway construction, rail laying and other projects.
Multi petal grab bucket: It is applicable to the grab and fractionation of waste steel in steel plants, the fractionation, loading and unloading and handling of large amount of waste and waste at garbage disposal sites and construction sites. The car recycling yard is used for the disassembly, fractionation and recycling of cars. The bucket teeth can be replaced and high hardness wear-resistant steel is used to ensure a long service life; The valve shell can be selected according to different working conditions; Fully closed valve shell, semi closed valve shell, wide side valve shell and narrow side valve shell.
The grab power form shall be selected according to the crane. According to the definition of grab bucket: grab bucket is a device for taking things under the crane, so even a grab bucket can not complete its work without the crane. On the contrary, no matter how large the tonnage of the ship unloader is, it can not be separated from the grab and has production efficiency. So what kind of crane should be equipped with what kind of grab, which can not be used if it is wrong, and can not be used if it is too large or overloaded. For example, the hoisting drum of the crane is single, and only a single rope grab can be equipped if a mechanical grab is needed. If a four rope grab is equipped, the grab will not work; Another example: if the rated lifting capacity of the crane is 25t, it is necessary to equip a grab bucket, which can only be equipped with the self weight of the grab bucket+the cargo weight of the grab=<25t. If the crane is overloaded, it is unsafe.
Application of excavator hydraulic grab:
1. Foundation pit excavation and deep pit excavation of building foundation and loading of mud, sand, coal and gravel. 2. It is especially suitable for digging and loading on one side of ditches or restricted spaces. 3. It is applicable to the loading and unloading of ships, trains and automobiles.
The clamshell grab crane is suitable for loading various bulk cargo, minerals, coal, sand and gravel, earthwork, etc. in ports, docks, station freight yards, mines, etc., and also can be used in earthwork excavation, foundation and ditch excavation, highway construction, rail laying and other projects. Petal grab crane. It is applicable to scrap steel grabbing and fractionation in steel plants, fractionation, loading and unloading and handling in garbage disposal sites and construction sites. The automobile recycling yard is used for automobile disassembly, fractionation and recycling. Bucket teeth can be replaced and high hardness wear-resistant steel is used to ensure long service life.
Which parts of the equipment are inspected and maintained by the grab crane manufacturer daily?
1. Smoothness largely depends on the working performance and service life of grab cranes. Smoothness is an important part of equipment maintenance. The smoothness directly affects the operation and service life of each mechanism, as well as the safety and efficiency of production. Therefore, it is necessary for operators and maintenance personnel to check the smoothness of the smooth points of the equipment frequently, and make up and replace the smooth oil in time.
2. Maintenance of motor and reducer. The motor and reducer have a great impact on the operating speed and efficiency of the crane. Maintain and inspect the motor shell, operating temperature, operating noise, vibration and other aspects, and solve the problems found in time and use them correctly. The daily maintenance of the reducer should be carried out according to the operating instructions. The foundation bolts of the reducer should be checked frequently and the connection should not be loose.
