Crane rail material grade

 


Crane rail material grade  

Crane rail material grades include low carbon steel, high yield strength steel, carbon steel, boron steel, and low alloy steel.

Crane rail is used for carrying heavy objects, which have high bearing capacity. Crane rail is also called crane rail. Its height is low and its head width and waist thickness are large. It is required to check the chemical composition and tensile strength. Used for laying crane and trolley rails.

Crane rail materials are manganese steel, carbon steel, high silicon copper, copper rail, silicon rail, and so on. The railway rail is composed of steel, which can be divided into ordinary manganese-containing steel rail, copper-containing ordinary carbon steel rail, high silicon copper-containing steel rail, copper rail, manganese rail, silicon rail, etc. Most crane rails adopt U71Mn, and most light rails are made of Q235 and 55Q; Most heavy rails are made of 45MN and 71mn

Among the crane rail material grades, U71Mn is the best material. Because adding 2-3% manganese into the steel, the low manganese steel is as brittle as glass. However, if adding > 13% manganese to make high manganese steel, it will become both hard and ductile. Therefore, people use manganese steel to make wear-resistant machine parts, bridges, and crane rails.

Study on the Influence of 40×60 Crane Rail Plate Stres

Study on the Influence of 40×60 Crane Rail Plate Stress The main operation mode of the overhead crane is the orbital operation, that is, the wheel supports the whole crane and transmits the gravity to the lower 40×60 crane rail , and the 40×60 crane rail receives the concentrated pressure from the crane wheel and guides the wheel to run. Therefore, the track device is the direct load-bearing structure of the crane device. Usually, special rails that meet the requirements of the wheels are used as crane rails. These rails are fixed with the pressure plate and the structure of the plant. If the crane runs at a slow speed, the operating frequency is not high, and the wheel pressure is not large, this solution can still meet the requirements. However, if the crane is in a high-speed, frequent or large-wheel working environment, the existing fixing method cannot meet the performance requirements. At this time, the phenomenon that the rail press plate bolt is broken is extremely likely to ...

What is crane rail system

  What is crane rail system What is the Crane rail system? The crane rail system consists of rail,  rail clip , rail joint,  rail pad , and other rail accessories. Crane rail is a crane running route laid by steel rail, which can ensure that the crane runs along the specified line and transmit wheel pressure to the foundation. The rail is usually composed of two-wheel rails. The top of the rail is convex, and the ground is a flat plate with a certain width, which increases the contact surface with the foundation. The section of the rail is mostly I-shaped and has good bending strength. When the crane is running, the rail cannot move horizontally and longitudinally, and the rail should be easy to adjust. The fixed parts of rail and rail shall be free of crack, looseness, and corrosion; If there is any crack, it shall be replaced in time, and other defects shall be handled in time. As for the installation of the crane rail system, there are two kinds of rail beams commonly ...
