Problems solved by technology

However, it is found in use that the width of the steel wing plate of the mast frame in the prior art is relatively large, the mast frame is increased from the second stage to the third stage, the thickness of the mast frame is increased, the working blind area is enlarged, and the operation convenience and safety are reduced.
To solve this problem, the forklift industry usually reduces the width of the mast-shaped steel wing to improve the field of vision, but this will lead to a decrease in the rigidity and safety of the mast
Although it can be compensated by increasing the strength of the material, the manufacturing cost will increase accordingly

Abstract

The invention relates to the technical field of machinery and material processing, and particularly relates to hot-rolled J-shaped steel for a forklift portal. The hot-rolled J-shaped steel for the forklift portal comprises a web, a first wing plate, a second wing plate and a third wing plate, and further comprises a first boss, a second boss and a wedge-shaped table, wherein the first wing plate and the second wing plate are positioned at the two ends of the lower surface of the web, and form a C-shaped structure with the web; the third wing plate is positioned at the position, far away from one end of the first wing plate, of the upper surface of the web; the first boss is positioned at the joint of the lower surface of the web and the left side surface of the second wing plate; the second boss is positioned at the joint of the upper surface of the web and the left side surface of the third wing plate; and the wedge-shaped table is positioned at the joint of the upper end surface of the second wing plate and the right side surface of the third wing plate. The hot-rolled J-shaped steel is wide in operation view, is high in rigidity, saves materials, and is low in hot-rolling difficulty and production cost.

Description

technical field [0001] The invention relates to the technical field of machinery and material processing, in particular to a hot-rolled J-shaped steel for a forklift mast. Background technique [0002] The mast is the lifting mechanism of the forklift. As the core working device of the forklift, safety and operation convenience are the key indicators to measure the advancement of the mast mechanism. The safety and operation convenience of the entire mast. In recent years, with the change of the working scene, the lifting height of the forklift has increased significantly. In response to this change, a three-stage mast came into being and gradually replaced the two-stage mast. The appearance of the three-stage mast realized that the lifting height was increased to 1.5 times the original under the condition that the height of the vehicle remained unchanged, which significantly improved the Adaptability to work scenarios. However, it is found in use that the width of the gan...
