Briefly describe the prerequisites for the installation of the rail clamp plates

1. Prerequisites for product installation
The rail clamp plate adopts an adjustable combined rail pressing plate, which can overcome the failures of the traditional rail pressing plate in use. The traditional pressing plate is often directly pressed with the rail steel to the steel rail in use. Some rail clamp plates can no longer be adjusted in the horizontal direction after installation, so after normal loading or thermal expansion and contraction caused by longitudinal movement of the track, it is easy to wear, causing the bolts of the clamp plate to loosen and the pressure plate to rotate, causing the surface of the track to wear and gnaw. If the rail is broken, the rail will be broken in severe cases, which will also affect the wear of the main engine wheels and the damage to the drive mechanism. When using the adjustable combined track platen, the track can be fixed in the horizontal direction, and the position of the track can be adjusted horizontally. For example, the QU80 rail clamp plates allow the lateral adjustment of the track to a distance of 15mm. For example, the QU120 pressure plate allows the lateral adjustment of the track to a distance of 20mm. And it has a self-locking function, which can reliably fix the track and prevent the track from shifting when it is pressed by a large wheel. Use elastic force to fix the track in the vertical direction. That is, the hot glue rubber tongue is pressed on the track indenter, and the tongue is made of synthetic rubber that is wear-resistant, oil-resistant, high-temperature resistant, and corrosion-resistant.
1. The installation of the rail clamp plates must be carried out after the adjustment of the steel beam on the lifting surface; the rail clamp plates
2. The crane steel beam must meet the requirements of the “Code for Construction and Acceptance of Steel Structure Engineering” (GBJ205-83) and the requirements of the current steel structure code;
3. The rail pressure device should be installed;
4. Before the installation of the rail presser, 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 rail joints should be connected, and the rail joints and side bending deviations should meet the requirements of the “Code for Steel Structure Engineering and Acceptance” (GBJ205-83). construction;
6. The welding of the base plate control plate and the steel suspension beam should meet the design requirements.

2. Installation sequence and essentials
A. Welding the fixed base, the fixed base can be used, the three grooves on the surface and the precise position of the rail presser can be positioned, and the allowable deviation of the position to the precise line of the crane beam is ±1.0mm;
B. Put in the T-bolts and push them into place in the direction of the rail;
C. Put in the wedge-shaped adjustment plate, and make the grooved side face up;
D. Install the rail pressure plate, washer, spring washer, and nut in sequence;
E. Move the wedge-shaped adjustment plate, adjust the position of the rail presser perpendicular to the direction of the rail, and tighten the nut after the rail pressing plate and the lower flange of the rail are tightly pressed;
F. The influence on the disturbance of the crane beam when the fixed plate is welded should be considered in the design or construction.

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. The dimensions of the 30 lb rail are as follows: Head width: 42.9mm Track height: 79.4mm Track bottom width: 79.4mm Waist thickness: 8.4mm GloryRail is an important  mining rail  supplier in China. Engaged in rail supply for more than 20 years. Rail products are exported to many countries and regions around the world. Trusted and supported by many mining customers. We maintain long-term cooperative relationships with many important customers in Peru, Colombia, Panama, and Venezuela in South America BUY 30 LB RAIL FROM CHINA As the world’s most important rail tracks production base. There are six major steel mills in China producing rails with an annual output of millions of tons. G...

Welding Process of Overhead Crane Rail Joint

Welding Process of Overhead Crane Rail Joint In order to make the overhead crane rail transport more stable, rail splints will not be used for the overhead crane rail joint connection, but welded joint connection will be used. The main key to the welded joint is to solve the bending deformation and weld cracking of the overhead crane rail joint. During the welding process of the overhead crane rail joint, the overhead crane rail joint is deformed downwardly, so the overhead crane rail end must be padded to a certain height before welding to ensure that the rail joint can be kept straight after the welding is completed. The height of the rail end pad is determined by factors such as the type of rail, length, fixing method and ambient temperature. The rails are fixed to the crane beam by means of hook bolts, and each joint is provided with four fixed points. After the bottom of the rail is welded, reduce the height to 20mm, and then tighten the hook bolts to continue welding. When the o...

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...
