Technical Specifications
The QL series includes ten models with varying capacities:
Capacities range from 3.2 tons to 100 tons, meeting diverse lifting needs.
Lifting heights span 110mm to 250mm, with overall heights from 210mm to 452mm.
Base diameters range from 93mm to 233mm, with top diameters from 52mm to 178mm, ensuring stability under heavy loads.
Design Features
Built with high-strength steel, these jacks feature a robust screw mechanism and a wide, stable base. The mechanical design eliminates the risk of hydraulic fluid leaks, making them ideal for outdoor and long-term use. The side-mounted handle allows for easy operation, while the compact form factor ensures portability.
