You’re equipping a workshop with an 8-meter eave height and a steel-frame roof structure. An overhead crane seems straightforward — until the structural engineer hands back the load assessment and tells you the roof trusses won’t carry a top-running system without reinforcement work that adds months and budget you don’t have. That’s the scenario where most procurement managers first encounter the underslung overhead crane: a system whose end trucks run on the bottom flange of existing structural beams rather than on top of dedicated runway rails, removing the need for support columns or structural upgrades in many retrofit situations. Underslung cranes won’t handle every application. For loads within 0.5–20 tons in facilities with limited headroom or existing beam structures, though, they deliver the same core lifting function at significantly lower installation cost and a shorter commissioning timeline. The market reference range for Weihua’s configurations runs from approximately $3,500 for a basic single-girder unit up to $45,000+ for a heavy-spec double-girder system. This guide covers Weihua’s underslung overhead travelling crane range — single-girder and double-girder variants, key specifications, headroom requirements, and…
