FAQ Section

What is the maximum load capacity for a railway maintenance screw jack?
Our railway maintenance screw jacks can handle loads up to 100 tons per unit, with options for higher capacities through custom designs. It's crucial to select a jack based on the specific weight requirements of your project to ensure safety and efficiency.

How often should railway maintenance screw jacks be inspected?
Regular inspections are recommended every 6 months or after 500 hours of use, whichever comes first. Check for signs of wear, corrosion, or damage to components like the screw thread and base. Lubrication should be performed monthly to maintain smooth operation.

Can these screw jacks be used in extreme weather conditions?
Yes, our jacks are built with materials resistant to temperature extremes, moisture, and corrosion. They operate effectively in temperatures from -20°C to 50°C, but always follow manufacturer guidelines for storage and usage in harsh environments.

What safety features are included?
Safety features include overload protection valves, non-slip rubber bases, mechanical locks to prevent accidental lowering, and bright warning labels. Always use in pairs or sets for balanced lifting and adhere to local safety regulations.

Are customization options available for specific railway projects?
Absolutely. We offer customization in load capacity, lifting height, operation type, and materials to suit unique project needs. Contact our engineering team with your specifications for a tailored solution.

Maintenance Tips

To ensure longevity and performance, clean the jack after each use, apply lubricant to moving parts, and store in a dry, cool place. Avoid overloading beyond the rated capacity and conduct periodic professional servicing. Replacement parts are readily available to minimize downtime.
