Mechanical jacks 

Mechanical jacks provide safe, controlled, and reliable lifting for heavy loads across industrial, construction, maintenance, and railway environments. Built with solid steel structures and mechanical self-locking mechanisms, they offer dependable performance for equipment installation, leveling, load positioning, and field operations.

How to Choose the Right Mechanical Jack

1. Identify Your Working Environment

Industrial facilities, construction sites, and railway fields each require different jack structures. Screw jacks suit heavy machinery, while rack and railroad jacks are better for outdoor or uneven-surface operations.

2. Determine the Required Load Capacity

Choose a jack that exceeds your maximum working load. For heavy-duty or safety-critical applications, select a unit with additional safety margin to ensure stable and secure lifting.

3. Select the Appropriate Mechanism

Screw jacks provide the highest precision and load stability. Rack jacks offer straightforward mechanical lifting for rugged environments. Spiral jacks serve light-duty lifting with compact storage advantages.

4. Consider Height Range & Ground Conditions

Evaluate the minimum and maximum lifting heights required for your equipment. Rack and railroad jacks excel on uneven ground, while screw jacks deliver precise elevation for equipment alignment.

Applications of Our Mechanical Jacks

  • Industrial Equipment Installation & Maintenance
    Mechanical screw jacks provide controlled vertical adjustment for heavy machinery, structural alignment, and assembly operations.
  • Construction & Infrastructure Projects
    Rack jacks and high-capacity screw jacks are widely used for material positioning, support tasks, and equipment elevation on construction sites.
  • Railway Maintenance & Track Alignment
    Railroad jacks ensure safe and accurate lifting of rails, track panels, and sleepers during installation, repair, and alignment missions.
  • General Mechanical Lifting & Field Operations
    Spiral and rack jacks support small equipment lifting, outdoor field work, and utility maintenance where compact, non-hydraulic solutions are required.
