Introduction to 3 Ton Gantry Cranes

The 3 ton gantry crane represents the ideal balance between capacity and versatility in material handling equipment. With a 3,000 kg (6,614 lbs) lifting capacity, these cranes fill the critical gap between light-duty and heavy-industrial solutions. At Dongqi Crane, we engineer our 3 ton gantry cranes to deliver:

• Precision load handling with ±5mm positioning accuracy
• Adaptable configurations for diverse industrial needs
• Energy-efficient operation that reduces lifetime costs
• Smart safety systems meeting global standards

Whether you need a rugged steel workhorse or a lightweight 3 ton aluminum gantry crane, this guide will help you make an informed decision.
