In brief: Kelude Heavy Industry provides crane configuration solutions for steel structure erection projects, covering the four key stages of member fabrication, assembly, hoisting and positioning, and welding. The solutions accommodate lifting capacities from 8 to 200 t and working radii from 10 to 50 m, with total lifting equipment investment ranging from approximately $445,000 to $8.9 million. LD-type overhead cranes (5–20 t) are deployed in the fabrication area, MH-type gantry cranes (16–50 t) in the assembly yard, truck or crawler cranes (25–200 t) for on-site erection, and compact jib cranes (1–5 t) in the welding area — covering the full range of hoisting needs for both steel fabrication shops and construction sites.

Crane Solutions for Every Stage of Steel Structure Construction
Fabrication shops require large-span overhead cranes to cover H-beam production lines. MH type gantry cranes handle pre-assembly of large components in the staging yard, while truck cranes take the lead for on-site erection.
Kelude Heavy Industry — Service Advantages
Kelude Heavy Industry has years of hands-on experience in steel structure erection, delivering complete hoisting solutions from component fabrication to on-site installation for industrial plants, sports stadiums, super high-rise buildings, and airport terminals. We hold a professional steel structure construction contractor qualification.
Overhead Crane Solutions for Fabrication Shops
Handling H-beams (12–24m long, 2–10t each) and box columns/girders in a fabrication shop calls for large-span overhead cranes. Kelude recommends LD type or QD type overhead cranes (5–20t, 18–36m span) equipped with variable-frequency speed control and an anti-sway system. Multiple cranes are strategically arranged across the shop to cover the cutting, tack-up, welding, and finished goods zones independently.
Gantry Crane Solutions for On-Site Assembly
The on-site assembly yard needs gantry cranes (16–50t, 20–40m span) to cover component unloading, tack-up, and welding operations. Kelude recommends MH type or MG type gantry cranes with rubber-tired or rail-mounted traveling. For large-span assembly yards, we suggest pairing two gantry cranes to work in tandem, using custom lifting spreaders to flip and translate oversized components with ease.
High-Altitude Erection Solutions
For high-altitude steel erection (columns, beams, space frames), truck cranes or tower cranes are deployed. Kelude offers a full range of 25–200t truck crane rental services. For super high-rise core walls and exterior frames, the crane model is selected based on the weight of each lifted segment and the tower crane's scope of coverage. Individual column segments weigh 8–25t, beams 2–8t, and high-strength bolt connection accuracy requirements are ≤2mm.
Frequently Asked Questions (FAQ)
Q: What size overhead crane does a steel structure fabrication shop need?
A: The heaviest components in a fabrication shop are typically box columns or box girders, with individual pieces weighing 5–15t. The required lifting capacity is calculated by multiplying the heaviest component weight by a 1.25 safety factor, which yields 6.3–18.75t. A 10t or 20t LD-type or QD-type overhead crane is recommended. The span is determined by the factory building width (typically 18–36m), while the lifting height is based on the maximum component height plus the spreader height and a safety margin (typically 8–14m). Kelude Heavy Industry recommends configuring multiple cranes within the shop according to functional zoning.
Q: What type of gantry crane is used for on-site steel structure assembly?
A: For on-site assembly yards, we recommend the MH-type single-girder gantry crane (lifting capacity: 16–32t, span: 20–36m) or the MG-type double-girder gantry crane (32–50t, span: 24–40m). The MH type offers lower investment cost and faster installation, making it ideal for assembling small to medium-sized components. The MG type delivers higher lifting capacity, greater span, and superior stability, making it well-suited for heavy-duty components and large-scale planar assembly. Rubber-tired gantry cranes provide flexible repositioning, while rail-mounted gantry cranes achieve higher travel speeds.
Q: What is the selection basis for truck cranes used in high-rise steel structure installation?
A: For standard floors of super high-rise steel structures, steel columns are segmented at 8–15 t per piece and steel beams at 2–5 t per piece. Tower crane selection is determined by the hoisting requirements of the heaviest component within the coverage radius — either a 50 t-class tower crane (lifting capacity of 5–8 t at R=40 m) or a 100 t-class tower crane (lifting capacity of 8–12 t at R=50 m). Truck cranes are deployed for low-rise sections and for supplementary lifts in areas beyond tower crane coverage. For high-rise steel structures, a configuration of one primary tower crane plus one auxiliary truck crane is recommended.
Q: What are the key safety management points for lifting and hoisting in steel structure projects?
A: Key safety management points for steel structure hoisting: ① Conduct a lifting plan technical briefing and working-at-height safety training before hoisting begins; ② Perform daily inspections of wire ropes, shackles, and lifting spreaders for wire breaks, wear, and deformation; ③ Set up warning barriers around the hoisting area and keep unauthorized personnel out; ④ Stop hoisting operations when wind speed reaches Force 6 (10.8 m/s) or above; ⑤ Do not release the hook until high-strength bolts have been fully torqued. Kelude provides full-process safety monitoring services for steel structure hoisting operations.
