1. Rotary snowplow
A rotary snowplow is a piece of railroad snow fighting equipment with a large circular set of blades on its front end that rotate to cut through the snow on the track ahead of it. The precursor to the rotary snowplow was the wedge snowplow. The rotary was invented by Toronto, Ontario, Canada dentist J.W. Elliot in 1869. He never built a working model or prototype, although he wanted to.In 2001, the rotary snowplow was inducted into the North America Railway Hall of Fame. The hall of fame recognizes and establishes and enduring tribute to the people and things that have made significant contribution relating to railway industry in North America. The rotary snowplow was inducted in the "Technical Innovations" category with "National" significance.
2. Tiger stone
The amazing machine, named Tiger-Stone, can create an instant road wherever it travels, laying out bricks in formation to create perfect paving.While the process may look magical, the secret behind the invention lies in a smartly-designed gravity-based system.All a worker has to do is load the bricks by hand from a hopper into the Tiger-Stone in the desired pattern. From there gravity causes them to slide together, in a sheet of paving, onto the ground.Brick roads have long been sought-after due to their attractiveness and durability but have become less common because of the labour-intensive work that goes into laying them, compared to other road surfaces such as concrete or asphalt. However, with a Tiger-Stone workers are able to lay out 400 square meters of new road every day, using paving stones or bricks, compared to a single conventional paver on their hands and knees who would only be able to manage between 75 and 100 square meters.
| 3. Replacing the sleepers without removing the rails |
Railroad tracks are made of three main parts: the long steel rails that the trains run on, wooden or concrete railroad ties (US) or sleepers (UK), and the track ballast that helps bear a train’s weight and keeps the track clear of plants. As a part of track maintenance, sleepers might need replacement, but they’re under the rails and crushed rock. How do you get them out? The machine uses its sleeper changer attachment to push the ballast away before grabbing the concrete sleeper to remove it. The rails are never disturbed. Watch as each step of the track rehabilitation process is explained, including how the sleepers are reattached to the rails using rail fastening clips before the ballast is smoothed back out.
4. Segmental bridge construction machine
This colossal machine is called the SLJ900/32, or the Segmental Bridge Launching Machine. Created by Beijing Wowjoint Machinery Co, it can build this viaduct by extending beyond the installed segments to span to the next support, and roll the next pre-made bridge segment into place.
5. Barrier transfer machines
Barrier transfer machines, also known as zipper machines or road zipper, are heavy vehicles used to transfer concrete lane dividers, which are used to relieve traffic congestion during rush hours.The vehicle contains an S-shaped channel in its undercarriage which lifts the barrier segments (which may weigh over 1,000 pounds (454 kg) off the road surface and transfers them over to the other side of the lane, reallocating traffic lanes to accommodate increased traffic for the currently dominant (peak) direction. These barriers are linked together with steel connectors to create a sturdy but flexible safety barrier.
6. Rallway construction machine
For the control and monitoring system of a new generation of railway lines electrification machines, Italian-based company Tesmec chose TTControl as technology partner for the constant tension stringing unit and the catenary maintenance diagnostic unit. By using TTControl's HY-eVision operator interface together with an HY-TTC 94 ECU and four HY-TTC 48X I/O modules, it was possible to integrate and manage all different functions of the catenary maintenance diagnostic unit. Additionally, a modular, flexible and adaptable system has been established thanks to the versatility and configurability of TTControl’s control units.
