Gantry / Portal Crane

The SIEC gantry crane (also called a portal crane) is a self-supporting lifting system with legs that travel on ground rails or rubber tires. It requires no building-mounted runway, making it the ideal solution for outdoor yards, storage areas, and locations without existing crane infrastructure.

Available in single-girder and double-girder configurations, with capacities from 5 to over 100 tons and spans up to 40 meters. The gantry crane family also includes the portable Light Aluminum Gantry for lightweight maintenance tasks.
