A 20 ton gantry crane is a medium-duty freestanding lifting system designed to handle loads up to 20 tons, with optional upgrades to 25 tons for occasional peak demands. Unlike overhead cranes that rely on building steel beams, it features a portal frame that sits directly on the ground, either on fixed concrete foundations or motorized wheels. Whether you're loading 20-ton containers, moving steel beams, or assembling machinery, this crane delivers reliable performance, easy maneuverability, and cost-effectiveness for you.

Advantages
1. Structure Optimization
The main beam adopts a box girder structure. The main welds are fabricated using submerged arc automatic welding technology. After welding, the beam undergoes shot blasting treatment to relieve stress. This design ensures higher structural strength and precision.
2. Safety performance
The main load-bearing components are connected with 10.9-grade high-strength bolts. The drum is manufactured by centrifugal casting. The hook can rotate 360 degrees and is equipped with a safety catch.
3. Work efficiency
Equipped with a large-diameter drum to reduce the bending fatigue of the steel wire rope and shorten the drum length to reduce the angle of the steel wire rope, thus extending the service life. The hook adopts anti-wear roller bearings from well-known manufacturers. The pulley is made of Q345B material through rolling and heat treatment, enhancing wear resistance and strength.
4. Maintain Convenience
The surface of the steel structure is coated with epoxy zinc-rich paint, with a film thickness exceeding 120μm. The control box is made of a cold-rolled steel plate and treated for corrosion resistance. During daily maintenance, the equipment can be quickly disassembled for inspection and repair, reducing maintenance costs.
Applications
Shipping & Logistics Yards: Loading/unloading 20-ton shipping containers from trucks or trains; stacking containers in outdoor storage yards.
Construction Sites: Lifting 20-ton steel beams, concrete precast panels, or HVAC units to upper floors; moving construction machinery across the site.
Manufacturing Workshops: Assembling medium-heavy machinery; moving raw materials to production lines.
Automotive Plants: Handling 20-ton car body assemblies or heavy dies for stamping operations; moving finished vehicles to storage areas.
Warehouses: Lifting heavy inventory that's too big for forklifts; accessing storage areas without building-mounted cranes.
