Wheelset lathes, equipment, and machinery made by the well-known company LONTRON are primarily used for maintaining urban rail stations and railway repair facilities. The products are widely utilized in modern trams, high- and low-speed EMUs, railroad locomotives, railroad passenger cars, and various other vehicles, including electric passenger cars for subways, diesel locomotives, rail grinding cars, and catenary vehicles.
The company provides complete solutions for the production and upkeep of railroad rolling stock.
It accrues a wealth of expertise and credentials in providing services like engineering, equipment integration, complex project management, and customer collaboration throughout the project's lifespan.
Lontron has years of expertise in making train bogie!
A bogie is an independent item installed on two wheels and used under lengthy vehicles. Each bogie has a bolster for interaction with the male counterpart beneath the vehicle's underframe.
Axles and wheels are connected to a bogie, a structure under the body of a railroad car, by bearings. The phrase "running gear" refers to both bogies and vehicles with two or more axles but no bogies. In this instance, guidance devices and springs—or, for very low speeds, even without springs—attach these axles to the vehicle's body directly.
In addition to having brake systems, drive systems, including gearbox coupling and traction motors for powered wheelsets, bogie frames with secondary spring systems, and the wheelset subsystems, essentially an assembly of two wheels and an axle, railway bogie are intricate subsystems in railroad vehicles.
Most modern railroad cars have bogies, which typically have two axles. Nevertheless, three-axle designs are employed in some circumstances, such as with larger and more powerful locomotives. Due to the decreased axle distance, fewer vehicles and vehicle sections are possible with bogie designs. On the other hand, compared to cars with axles supported directly by the vehicle body, bogie vehicles offer far higher riding comfort.
One such product is Underfloor Vehicle Bogie Machine Vision System. The wheelset heavy maintenance workshop has installed LAC Dismounted Wheelset Ultrasonic Testing equipment. A combination of modern phased array ultrasonic and traditional ultrasonic testing technology is used to identify cracks in the wheel and axle. Three distinct inspection configurations—wheel or axle inspection only, simultaneously, or both—could be appropriate for various needs and are simple to upgrade afterward functionally. The LAC system could tightly monitor Wheelset maintenance quality with routine ultrasonic testing. It can be used with any type of vehicle, including metros, EMUs, locomotives, and passenger and freight rolling stock.

Y25 Welded Frame Bogie
Principal performance indicator
Axle Load 20 Tons
Track Gauge 1000mm, 1067mm,1435mm,1520mm,1676mm
Design Speed 120 km/h
Max. Running Speed 100 km/h
Low Track Force Bogie
The bogie is an upgraded three-piece casting bogie. Its key characteristic is as follows: To reduce the unsprung mass and, consequently, the dynamic forces between the wheel and track, a primary rubber pad is inserted between the side frame and adaptor.
A cross-bar connection is inserted between the side frames to increase the vital hunting speed.
Green, quiet, and with minor wear on the tire tracks.
Principal performance indicator
Axle Load 23/25 Tons
Track Gauge 1000mm, 1067mm,1435mm,1520mm,1676mm
Design Speed 120 km/h
Max. Running Speed 100 km/h
Min. Radius curvature negotiable 100m
Mark VII Self-steering Bogie
The bogie is an upgraded three-piece casting bogie. Its primary feature is the addition of a self-steering system between the wheels.
