Railway Screw Jack – Reliable and Durable Mechanical Jack for Heavy-Duty Applications
The railway screw jack is a solid, fully mechanical device designed for lifting heavy loads, vehicles, and structural components. Its design, based on a rack-and-pinion mechanism and a hand crank, allows safe and precise lifting without the need for electrical or hydraulic power. It is a trusted solution across the railway industry, heavy industry, construction, and technical maintenance sectors.
It stands out for its simple yet extremely durable construction made of high-strength steel. The entire surface is coated with a powder finish resistant to corrosion, moisture, and mechanical damage. The jack can operate in demanding field conditions, while its massive base ensures stability and safety when lifting even large loads.
Thanks to the use of a worm gear and a ratchet safety mechanism, the railway screw jack maintains the load in position without the risk of accidental lowering. The crank rotates smoothly and easily, allowing the operator to precisely control the lifting height. Depending on the model, the device offers various lifting capacities and working ranges, enabling it to be tailored to the user's specific needs.
Main features of the railway screw jack:
✅ Mechanical design – no electrical power required, fully independent in the field.
✅ High load capacity – ideal for working with heavy structural elements, machines, and vehicles.
✅ Precise adjustment – enables accurate control of the lifting height.
✅ Ratchet safety system – protects against accidental load descent.
✅ Weather resistance – ensured by a solid steel housing and powder coating.
✅ Easy operation and maintenance – a simple mechanism guarantees years of trouble-free service.
Applications:
Railway screw jacks are mainly used for track, assembly, and maintenance work in railway infrastructure. They are also perfect for use in the construction, shipbuilding, and mechanical industries – wherever power independence and high lifting force are required. They can be used for supporting railcars, lifting tracks, steel structures, or heavy machine components.
Why choose a railway screw jack?
This device combines simplicity of use with exceptional durability. The absence of hydraulic and electronic systems means it requires virtually no servicing, ensuring reliable performance in any condition. Its compact design allows for easy transport and operation in the field, making it an ideal solution for maintenance teams, technical services, and industrial plants.
