Description

Product performances: 

The utility model is suitable for connecting the 50 and 60kg/m rails and the prestressed concrete sleepers, the prestressed wide concrete sleepers and the integral track bed of the straight line on the R>=300m line of the standard gauge railway. When installed, the straight section and R>=650m curve section, nut torque control in 80-120N*m, in the R<=650m radius area, torque control in 120-150N*m nut. The height of the rail top is adjusted by padding the adjusting pad and the maximum height is 10mm.The track gauge is adjusted by the combination of different types of gauge baffle and baffle seat. The adjustment amount of 50kg/m rail is -8 - +16mm, and the adjustment amount of 60kg/m rail is -8 - +12mm. 

Material: 

Type I: play article made from 13 mm diameter hot rolled round steel spring 60 si2mn. 

Type II: 60 si2cr high quality spring steel

Manufacturer:

Henan Great track machinery Co. LTD.

Packaging: 

Bagged

Uses: 

It is calculated by the bending and twist deformation, buckle pressure effect on the orbit, effectively guarantee the reliable connection between rail for a long time, as far as possible to keep the integrity of the orbit and stop the rail lateral movement relative to the sleeper, ensure the normal track, to ensure the safety of the rail vehicle.

Advantages: 

Good elasticity, low pressure loss, good keeping track geometry. Large pressure, large strength safety reserves, small residual deformation.

Company profile: 

Henan Great Track Machinery Co.,Ltd. is located in the origin of Chinese civilization and the hometown of Oracle which is a world cultural heritage—Anyang City, Henan Province, which is adjacent to Anyang steel company and Handan steel company that belong to 500 strong  large enterprises in China. There is transportation in all directions, rich in resources, outstanding people, which provide a unique condition for the production and development of enterprises.

The main products include: 

screw spike, elastic strip, gauge baffle, flat washers, spring washers, nuts, square spike, square head wood screw spike, ordinary bolt, high strength bolt, guard rail buckle, spindle head buckle, common rail rod, insulated gauge rod, ordinary fish plate, guard rail shuttle end, nylon flapper seat, rubber cushion, stop buffer, switchman, base plate, turnout base plate, railway tools, railway tunnel and highway railway fastener protective net.

Product description:

A special elastic structure makes rail clip also has the absorption of impact energy produced when a vehicle goes by, to achieve the effect of shock absorption. Rail clip is in repeated alternating stress, and it is subjected to bending and torsion fatigue and corrosion and other effects in the vehicle through, but also bears the high instantaneous impact load, so the performance of elastic strip is very strict. It can be seen that although it is a small engineering component, it is an important part of the track. Because of its large demand and about 7000 pieces per kilometer, its reliability is directly related to the safety of traffic.

Technical parameters: 1. The nut torque is 10 kg. J m, play the initial pressure of rail is 14.9 KN, when the torque is 15 kg.m, the initial pressure of 27.4 kN. 2. Each longitudinal creep resistance of fasteners is 8KN, resistance to horizontal thrust of 80 kn. 3. When the abrasion rail insulating buffer plate under compression up to 3 mm, play a button on the rail pressure can still keep 7.9 9.7 kN.

Features: 

1. The material of the bullet bar is 60Si2Mn or 55Si2Mn hot-rolled spring, and the technical requirements should comply with GB 1222. 2. The hardness of the cartridge is HRC41 ~ 46. 3. The metallographic structure of the projectile should be homogeneous in the tempering strophes and the sorbite body, and the center of the heart is allowed to have a small amount of the discontinuous ferrite. 4. The bullet bars shall not be overheating or over burning. The depth of surface decarburization shall include no more than 0.3mm of pure iron and transition layer. 5. After residual deformation test, the permanent deformation value of the front end shall not be greater than 1mm..

News: 

In August, there were 350,000 pieces of the label

In August 2017 is to be proud of Henan Great rail company for a month, the winning play the Shanxi west extension line article buckle accessories article 290000 sets of elastic type I buckle accessories, article Jiang xi jiu Jing qu railway the winning play scene separated type fastener 60000 sets, and sign the rail cooperation agreement with the Zhengzhou subway line one, in front of the company is preparing to produce, for domestic railway business offer.
