Gantry crane rail track structure and function description

      In engineering, electric  hoist gantry crane  rail mounting is in between a mechanical and civil engineering fields. Rail mounting is often installed by the plant construction side, while the cranes are cranes installed by the qualified units installed, the two are often out of touch. In engineering construction crane mounting rail track rail mounting beams and often by the two professional (such as civil and mechanical installation) to complete, also there is a disconnect between the two professions.

      Therefore, the electric hoist gantry crane rail installation quality is difficult to be truly guaranteed. Crane rail mounting a direct impact on the quality of the operation of the  hoist crane   Only grasp the quality from the source, in order to ensure the quality of crane rail mounting.

      Crane crane rail track has, railroad rails and square steel. The convex top of the rail and the bottom plate having a certain width, to increase the contact surface with the base; track-shaped cross section, mostly, with good flexural strength. Square steel flat top rail can be seen, due to wheel wear and generally used only for lifting small, run slower, work is not frequent cranes. Rails usually carbon, high manganese steel (C = 015% ~ 018%, Mn = 016% ~ 115%) from rolling. Electric hoist  gantry crane  rails Typical materials for the U71Mn steel. Mainly used square steel Q275 square steel or flat steel.

      Electric hoist gantry crane is used as a crane rail carts and trolleys with special cross-section rails, standard length 9,915,10,1015,11,1115,12,1215 etc. 8. Common specifications for QU70, QU80, QU100, QU120, QU behind the numbers that track width of the head. Railroad rails of two kinds of heavy rail and light rail, rail specifications per meter length with a nominal weight. Weight greater than 30kg / m rail, heavy rail belongs. Standard rail length 12150m and 25100m2 kinds of specifications. LRT is not more than 30kg / m rail, generally the length of 5 ~ 12m. Rail steel, mostly ordinary carbon structural steel and semi-killed steel killed steel, to improve rail wear and corrosion resistance, in recent years, using Mn, Si, P and other alloying elements in low-alloy structural steels.
