When it comes to the core of a car, it is estimated that many people will think of the engine. However, for a forklift, its core is not the engine, but the forklift gantry,
There are many kinds of forklifts, but no matter how they are divided, they all have a common component - gantry. Let's see if the forklifts in the figure below all have gantry?
One of the important components of the whole structure of the gantry is the gantry channel steel, which is the supporting component for lifting, moving, loading and unloading goods of forklift. It is made of pure steel, which can be described as the steel core of forklift.
Classification of portal channel steel
C100, C120, C300 and other limit forklift gantry channel steel are mainly used for small tonnage electric forklift and super large tonnage internal combustion forklift, which can meet the needs of special forklift such as storage and wharf. The shape is as follows:
The gate frame channel steel of limit forklift such as J100, J120 and j300 is mainly used in small tonnage electric forklift and super large tonnage internal combustion forklift, which can meet the needs of special forklift such as storage and wharf.
H-shaped gantry section steel can effectively increase the lifting load of forklift, and has higher requirements on the center deviation and dimensional consistency of products, mainly including H100, H120, h130 and other specifications.
Let's take a look at the collective photo of the portal channel steel. The lower right corner is the forklift beam, which is also the indispensable portal section steel on the portal.
The development of forklift is changing with each passing day. With the development of domestic forklift, the requirements for gantry channel steel are higher and higher, and the dimensional accuracy is improved by ± 1 mm, up to the present level ± 5 mm (it's really difficult for section steel), and the material properties have been improved from simple 20MnSi with yield strength of 335 MPa to Q460C with yield strength greater than 460 MPa. The specifications have also developed from small C100 to large C300, and the cross-section shape has developed from simple C-section to complex special-shaped section, realizing J-shaped groove, asymmetric C-shaped groove and asymmetric C-shaped groove In the future, the precision, performance, shape and surface quality of portal channel steel with high difficulty, such as j-groove, will be greatly improved.
