Types Of Railroad Components

The railroad components produced by our company mainly include the following types:

 

Rail Lag Bolt
A Rail Lag Bolt, also called sleeper screw, rail screw or lag bolt, is a medium or large metal screw used to fasten a rail base plate or rail. Such spikes are always fastened into holes bored into the tie sleeper.

 

Forged Wheel
A forged wheel is an advanced type of wheel that is produced through the process of forging, a manufacturing process where metal is shaped using localized compressive forces.

 

Tamper Swivel Bracket
The Tamper Swivel Bracket is a rotating bracket used for vibration compaction equipment.

 

Anti-Creepers
Rail anti-creepers, also known as rail anchors or rail clips, are components used in railway systems to prevent the lateral movement or "creeping" of rails.

Advantages Of Railroad Components

Rail Lag Bolt

Rail lag bolt have many advantages, including:
Load-Bearing Capacity:
They can withstand significant stress and loads, making them suitable for applications requiring high strength.
Secure Connection:
The coarse threads and thick shafts of lag bolts grip the material more securely than regular wood screws, preventing loosening over time.
Threading:
The threading on lag bolts helps prevent them from loosening over time due to vibrations or external forces.
Pointed Tip:
The pointed tip of the lag bolt acts as a self-drilling pilot point, which reduces the risk of wood splitting.

Forged Wheel

Forged wheel have many advantages, including:
Low weight. Forging weighs almost half as much as stamped steel wheels, and a third less than cast wheels. This leads to reduced load on the chassis.
Resistance to corrosion and the effects of road reagents.
Plasticity. The fiber structure improves the flexibility of the metal, so in a strong blow the rim is more likely to bend than crack.
Inexpensive to repair. Small deformations that may occur during use or in a traffic accident are eliminated by rolling on the machine, which are available at most service stations.

Tamper Swivel Bracket

Tamper swivel bracket have many advantages, including:
Easy Accessibility for Maintenance and Adjustments:
The ability to swivel the mounted item allows for easy access for maintenance and adjustments without having to remove the entire bracket.
Earthquake Brackets:
Some tamper-resistant brackets are designed to serve as earthquake brackets, ensuring that items remain securely mounted during seismic activity.
Cost-Effective Solutions:
Swivel brackets can provide cost-effective solutions for mounting and securing various items without complex installations.

Anti-creepers

Anti-creepers have many advantages, including:
Adapt to Temperature Changes:
Anti-creepers are crucial in preventing rail expansion and contraction due to temperature fluctuations, which can lead to buckling and damage.
Withstand Heavy Traffic:
Rail anchors are designed to withstand the immense forces generated by heavy train traffic, ensuring the track remains stable under pressure.
Improve Safety:
By preventing rail movement, anti-creepers contribute to a safer environment for passengers and railway workers.

Application Of Railroad Components

 
 
Rail Lag Bolt

Rail lag bolt can be used for a variety of purposes, including: Rail lag bolts differ from other types of screws, like drywall screws and deck screws, because they are designed to drive into wood with a wrench or socket.

 
Forged Wheel

Premium Automotive:
Many luxury and high-end car manufacturers use forged wheels for their superior strength, lightweight design, and aesthetic appeal.
Motorcycles:
Forged wheels are also used in the motorcycle industry, particularly for high-performance and racing applications, offering a lighter and stronger alternative to cast wheels.
Off-Road Vehicles:
Forged wheels can provide the strength and durability needed for the demanding conditions of off-road driving.

 
Tamper Swivel Bracket

Fire Sprinkler Systems: Used to mount and monitor OS&Y valves and other control valves, ensuring they are always operational in an emergency.
Security Systems: Used to mount motion sensors, allowing for flexible positioning and detection of tampering or unauthorized movement.

 
Anti-creepers

Railway lines: Installing track anti climbing devices on railway lines can prevent people from entering the track area without permission.
Subway platforms: Subway platforms are relatively easy to access tracks, so measures need to be taken to prevent people from approaching or crossing the edge of the platform.
Track tunnel: The use of track anti climbing devices on the tracks at the tunnel entrance or inside the tunnel can effectively prevent personnel from entering the tunnel and avoid causing dangerous situations.

 

 

Railroad Components Ordering Process
 

Here’s a look at the entire process of manufacturing and shipping railroad components:

Design and manufacturing time

We start by designing and manufacturing the railroad components. This includes refining raw materials, forging, and machining to ensure high precision and quality.

Packing and boxing time

Our staff carefully packs the forged wheels in protective cartons. This step is quick and ensures that all products are secure for transportation.

Custom clearance and loading time

The packed products are loaded onto vehicles. After clearing customs, the products are transported to various dispatch points.

Sea and land transportation time

Once the products arrive at their destination, you will receive an alert. You can then plan how to collect your shipped goods.

 

FAQ

 

Q: How do you determine the shear strength of a lag bolt?

A: The shear strength of a lag bolt is determined by its diameter and the material it’s embedding into. Manufacturer specifications often provide strength ratings, but a structural engineer can give a precise assessment for critical applications.

Q: What are the common sizes of forged wheels?

A: Forged wheels are available in a wide range of sizes, from 16 inches to over 24 inches in diameter. The size chosen depends on the make and model of the vehicle, as well as the owner's preference for performance or aesthetics.

Q: How are forged wheels tested for quality?

A: Forged wheels undergo rigorous testing to ensure they meet safety and performance standards. This includes load testing, impact testing, and visual inspections to check for defects or imperfections.

Q: What distinguishes a lag screw from a carriage screw?

A: A lag screw has a coarse thread and is used where high strength is necessary, while a carriage screw has a smoother thread and a rounded head with a square section underneath.
