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.

What are railway rail fasteners？

What are railway rail fasteners？ Railway rail fasteners Railway rail fasteners are a kind of railway accessories. The parts used to combine rails and sleepers (or other types of under-rail foundations) on the track are also called central joint parts. Its function is to fix the steel rail on the sleeper, maintain the gauge and prevent the longitudinal and lateral movement of the rail relative to the sleeper. The railway rail fastener system is divided into the shrapnel fastener system, gusset fastener system, and elastic strip fastener system. The gusset-type fastener is composed of a gusset plate, a threaded spike, a spring washer, an iron seat, and a buffer pad. The threaded spike is anchored in the reserved hole of the concrete sleeper bearing platform with sulfur cement mortar, and then bolts are used to fasten the buckle. Plate fastened. There are elastic strips I, II, and III types of clip fasteners. Type I elastic strip is composed of ω elastic strip,  screw spike , gauge b...

Rail clip installation

Rail clip installation rail clip installation Prerequisites for the rail clip installation 1. The rail presser is installed after the steel beam on the crane rails surface is adjusted; 2. The steel beam of the crane must be 3. The rail pressure device should be installed; 4. Before the installation of the  rail clamp , the surface paint of the crane beam is finished and meets the requirements of the current regulations; 5. Before the installation of the rail presser, the track joints should be connected, and the track joints and side bending deviations should meet the requirements of “Steel Structure Engineering and Acceptance Specifications”-83). 6. The welding of the base plate control plate and the steel suspension beam should meet the design requirements. Installation sequence and essentials A. Welding the fixed base, the fixed base can be used, the three grooves on the surface and the position of the rail presser can be positioned, and the allowable deviation of the position ...
