Condition: new, Year of construction: 2026, 10 Ton Railway Rack Jack – Heavy-Duty Mechanical Lifting Solution The 10-ton railway rack jack is a reliable lifting device designed for handling extremely heavy loads. Its robust construction, based on a rack-and-pinion mechanism and a solid crank drive, ensures safe and precise lifting of heavy components. Thanks to its fully mechanical design, the jack does not require electrical or hydraulic power, making it an indispensable solution wherever mobility, independence, and operational reliability are essential. The 10-ton mechanical jack has been designed for applications in heavy industry, railway transport, construction, and technical service operations. It is ideal for railway maintenance works, supporting rail vehicles, lifting steel structures, machine components, and prefabricated elements. Overload-resistant construction The solid body, manufactured from high-strength steel, is protected with a durable powder coating resistant to corrosion and mechanical damage. This allows the 10-ton crank jack to be used both in industrial halls and in demanding outdoor conditions, such as railway tracks, construction sites, and production facilities. The massive base provides excellent stability during operation, while the precisely manufactured rack mechanism ensures smooth movement without jamming. The crank handle operates easily and enables gradual lifting of heavy loads with minimal effort from the operator. Safety and lifting control The jack is equipped with a reliable locking pawl mechanism that effectively prevents accidental lowering of the load. This ensures safe operation when working with heavy components and gives the operator full control over the lifting and lowering process. An additional advantage is the simple mechanical design – the absence of hydraulic and electrical components reduces the risk of failure and lowers operating costs. Regular lubrication and basic maintenance ensure long service life and reliable operation for many years. Advantages of the 10-ton crank jack: ✅ 10,000 kg lifting capacity – suitable for heavy machinery, structures, and vehicles. ✅ Mechanical design – independent of external power sources and ready for use anywhere. ✅ High safety level thanks to the reliable locking mechanism. ✅ Precise height adjustment enables accurate positioning of the load. ✅ High resistance to external conditions – moisture, dust, vibrations, and low temperatures. Psdexqxwmepfx Ac Ajgt ✅ Easy transportation – compact dimensions and ergonomic construction. ✅ Wide range of applications across various industries. Technical specifications – MJ10 Parameter Value Model MJ10 Rated lifting capacity 10,000 kg Head width 120 mm Base width 140 mm Overall height 785–1160 mm Foot lifting range 70–450 mm Foot length 80 mm Body thickness 73 mm Base length 175 mm Gearbox height 330 mm Body width 252 mm Gear axis distance 185 mm Support length 230 mm Side housing length 250 mm Net weight 45 kg
