Installation Knowledge about Crane Rail

Installation Knowledge about Crane Rail
In engineering, the crane rail installation in an engineering field between machinery and civil engineering. Crane rail are often installed often by the plant construction side, but the cranes are often installed by the companies who have caran installation qualification. So the crane rail installation and the crane installation are often disconnected. Installation of rail beams and crane rail installation in engineering construction are often done by two majors (such as civil engineering and mechanical installation), and there is also a disconnect between these two majors. Therefore, it is difficult to ensure the quality of the crane rail installation. The quality of the crane rail installation directly affects the quality of the crane’s operation. Only by grasping the quality control from the source can the crane rail installation quality be guaranteed.
There are two types of crane rail beams used for rails installation, one is a steel structural beam and the other is concrete precast beam. Concrete precast beams must have pre-buried holes for bolting during installation or for pre-embedded bolts in concrete precast beams. The installation method of the crane rail includes plate fixing method, hook screw fixing, welding and bolt fixing. For horizontal adjustment, the holes in the rail presser are usually made as long holes, and the vertical adjustment can be placed under the rail. The rail press plates should be designed with sufficient rigidity. Each press plate can be made into single hole or double hole depending on the force. Only when the crane rail is connected to the rail beam or the steel plate fixed on the rail beam by welding, the gear can be welded to the rail. The position of the reserved bolt hole along the transverse and longitudinal directions of the beam muest be ensured ≤5mm during rail beam production. The diameter of the bolt hole is 2mm to 7mm larger than the diameter of the bolt. The top surface of the beam should be flat, but it should not be smoothed. The deviation of the center position of the rail beam from the design positioning axis is ≤ 5 mm. The deviation of the elevation of the top surface of the beam from the design elevation is +10mm/-5mm. The bolt holes reserved on the beam and the displacement deviation of the reserved bolts to the beam center are ≤5mm.

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...

30 LB RAIL FOR SALE

30 LB RAIL FOR SALE What is a 30 lb rail? A 30 lb rail refers to a rail weighing 30 lb in meters, which is an ASCE 30 model rail produced according to ASTM A1. As a common light track, it is mainly used for laying mining track lines. Therefore, it is widely used in the South American market.

There are six major steel mills in China producing rails with an annual output of millions of tons. G...

What are seamless rails? seamless rails Continuous seamless rails, also known as a welded long rail line, is a line that welds ordinary rails without leaving rail seams. meters or longer. The long rails are laid and fixed on the sleepers within the specified temperature range. There are rail slits at the end of the long rail, and the middle part cannot expand or contract with the temperature rise and fall. Therefore, the middle section of the steel rail will generate a large temperature pressure in summer and a large temperature tension in winter. The large pressure and tensile force in the rail can be calculated according to the annual high and low temperature of the place where the rail is laid. The large pressure on the rail should not cause the rail to buckle, and the large tensile force should not cause the rail to break. The seamless rails line greatly reduces the rail joints , reduces the impact on the rails when the wheels pass through the joints, is conducive to s...
