If your workshop has no corbels or supporting ledges on the concrete columns, a standard overhead crane cannot be installed. A freestanding runway crane uses independent steel columns with base plates anchored directly to the concrete floor, eliminating the need for building modifications. This saves significant structural renovation costs and time.
Yes. The freestanding design requires no attachment to your building structure, meaning installation can be carried out with minimal disruption. Most installations are completed within 2–4 weeks with production downtime kept to a minimum.
Capacities range from 1 ton to 25 tons (standard), spans from 3 m to 25 m, and lifting heights from 3 m to 18 m. Everything is fully customizable based on your workshop dimensions and material handling needs.
Cost depends on capacity, span, height, configuration (single/double girder), hoist type, control system, electrical brands, and surface protection. Contact Yuantai Cranes with your workshop details for a tailored quotation.
A reinforced concrete floor with minimum thickness of 150 mm is required. Freestanding columns are anchored using anchor bolts and base plates. Yuantai Cranes provides foundation drawings for your civil contractor.
