Yuantai Crane specializes in double-girder overhead bridge cranes for heavy-duty lifting applications. These cranes are engineered for high-capacity work – lifting 30, 40, 60, and up to 100tons – and are built to demanding industry standards. They serve heavy industries like steel mills, shipyards, power plants, and foundries. For example, Yuantai's double-girder 30–100ton cranes are used as industrial overhead cranes for steel plants and even as bridge cranes for shipyards. Each model is customizable (span, lift height, controls) and carries ISO9001, CE, and FEM certifications.
Yuantai Heavy-Duty Crane Models
Yuantai offers a lineup of heavy-duty overhead cranes in the 30, 40, 60, and 100ton ranges. All are double-girder, top-running cranes suited to long spans and heavy lifts. Key specifications of each model include span, lift height, and power requirements (typical values shown below):

- 30-Ton Bridge Crane: 7.5–31.5m span, up to 26m lift height. Voltage 380V/50Hz or 480V/60Hz options. IP55–IP67 protection.
- 40-Ton Bridge Crane: 10.5–31.5m span, up to 26m lift height. Voltage 220–440V (50/60Hz). IP55–IP67 rated.
- 60-Ton Bridge Crane: 6–31.5m span, lift height 6–26m. Voltage 220–440V (50/60Hz). Protection IP44–IP67.
- 100-Ton Bridge Crane: Heavy-duty double-girder design. Typical spans 10–35m, working classes A5 or higher. (Yuantai can custom-build spans and duty classes as required.)
Each crane is built with high-integrity steel girders and heavy-duty end trucks. For example, a 60-ton model uses two parallel main girders on robust end carriages to support the load. The hoist unit (wire-rope or rack & pinion) runs on a trolley between the girders. Yuantai's cranes include features like built-in maintenance walkways on the bridge and easy access to the hoist, similar to industry-leading designs.
Key features of Yuantai heavy-duty models:
- Custom Configurations: Span, lifting height, and controls can be tailored. Standard duty is heavy (FEMA5/A7/A8) for continuous industrial use.
- High-Capacity Hoists: 60t and 100t cranes use heavy wire-rope hoists with multiple fall blocks. 30–40t cranes may use compact windlass hoists.
- Power & Control: Three-phase motors (380–440V, 50/60Hz) with AC variable-frequency drives. Options include radio remote or cabin control.
- Environment: Protection ratings IP55–IP67 (dust/water sealed). Operating temperature typically –20℃ to +40℃ (can be customized).
Yuantai's 100-ton cranes are often used in expansive facilities. By industry convention, a 100t overhead crane is classified as heavy-duty and almost always uses a double-girder structure. The main girders carry the trolley and hoist, while the entire bridge travels on runway rails.
30-Ton & 40-Ton Cranes
Yuantai's 30t and 40t bridge cranes share many design elements. Both are double-girder EOT (Electric Overhead Travelling) cranes suitable for factories, warehouses, and mills. Standard spans range up to about 31.5m, and lifts reach as high as 26m. Both models include:
- Robust girders and end trucks for stability under 30–40t loads.
- Electric hoists with mechanical hooks; options for grab or electromagnet attachments.
- Frequency-driven controls for smooth acceleration/braking.
Applications for 30–40t models include medium-scale steel fabrication, equipment assembly, and general material handling. These cranes often replace multiple smaller cranes to improve efficiency. Yuantai also offers specialized variants in these capacities, such as grab cranes for scrap handling and electromagnetic cranes for steel sheets.
60-Ton Crane
The 60-ton bridge crane is a truly heavy-duty solution. It uses a double-girder design with very strong girders and high-capacity wheels. Key components include:
- Bridge & Girders: Two parallel box girders spanning the bay.
- End Trucks: Large-carriage assemblies with multiple wheels on heavy rail.
- Hoist: A 60t wire-rope hoist with heavy-duty drum and hook block.
- Trolley: Carries the hoist across the bridge.
Yuantai's 60t crane can lift very large loads (e.g. steel molds, turbine parts) and thus has a "double girder overhead crane design for enhanced stability and load-bearing capacity". Common applications for 60t cranes include power plant maintenance, large machinery assembly, and warehouse heavy loads. In steelmaking plants, the 60t ladle crane variant (with heat-resistant components) safely transports molten metal. Other 60t variants include grab-cranes for bulk materials and magnet cranes for scrap steel.
60Ton Specifications (typical): Span up to 31.5m; lift height up to 26m. Protection class IP44–IP67. Service class A6–A7 for foundry duty.
100-Ton Crane
For the 100-ton class, Yuantai builds a true large-capacity crane. These are double-girder top-running cranes with enormous girders and very robust structure. A 100t crane often spans well over 20m and may lift 10–20m depending on the building height. Typical uses include heavy steel plants (lifting slabs or coils), shipyards (moving large hull sections), and heavy component plants.
Yuantai's 100t models can be configured in various styles: standard EOT, European-type box-beam, explosion-proof, or underhung. For instance, explosion-proof versions use non-sparking parts for hazardous areas. Yuantai notes that 100t cranes (and even larger) follow international heavy crane standards.
100Ton Features: Double-girder box beam structure. High-class steel (FEM A7/A8). Customizable span and height. Overload protection and multiple hoist speeds. Optional second trolley for dual-lift tasks.
Even though few sources quote exact 100t specs, industry data says heavy double-girder cranes typically reach spans of 10–35m and duty classes A3–A5 or higher. Yuantai's designs align with these norms while offering flexibility for spans, speeds, and control interfaces.
Design and Safety Features
Yuantai heavy-duty cranes incorporate modern engineering features to ensure durability and safe operation. Key design elements include:
- Modular Steel Structure: The bridge and girder plates are cut and welded with precision (CNC cutting, automated welding). Nondestructive testing (ultrasonic, X-ray) verifies weld integrity.
- Reduced Weight & Wheel Loads: Optimized girder profiles give high strength with less deadweight, which lowers rail loads and infrastructure costs.
- Variable-Frequency Drives: All motions (bridge travel, trolley travel, hoisting) use VFD controls. This provides smooth acceleration, deceleration, and better energy efficiency.
- Synchronization (Multi-hook): Yuantai offers coordinated multi-crane operation. Multiple hoists on the same bridge can synchronize to lift very long loads evenly.
- Anti-Sway Control: Advanced anti-sway algorithms automatically dampen load swinging, improving precision. (Industry testing shows up to 60% faster handling with sway control.)
- Limit Switches & Brakes: All travel axes have upper/lower limit switches. The hoist and bridge each have failsafe brake systems: an electromagnetic brake plus mechanical disk for no-drop safety even on power loss.
-
Overload Protection: Cranes include load-sensing devices or overload relays that stop hoisting if load exceeds the rated capacity. This is a standard requirement on double-girder heavy cranes.
- No-Voltage Protection: Controls include a "no-voltage" cutoff so that loss of control power triggers a safe stop.
- Collision and Zone Protection: Optional features (furnished by Yuantai or third parties) include crane collision detectors, end-of-travel energy absorbers, and geofencing to prevent entry into off-limits areas.
- Ergonomic Control: Operator cabins (if used) have safety glass, climate controls, and unobstructed views. Yuantai also offers pendant or wireless remote control for safer ground operation.

Application Industries
Heavy-duty overhead bridge cranes are vital in industries that handle large, heavy materials. Yuantai's 30–100t cranes serve many sectors:
- Steel & Metallurgy: Steel mills use these cranes to move slabs, coils, and scrap. (A 60t magnet crane can lift metal ingots; a 30–40t crane transfers coils in processing shops.)
- Foundries: High-capacity ladle cranes (e.g. 60t ladle cranes) carry molten metal between furnaces and casting areas. These "foundry cranes" have heat shields and dual braking for safety.
- Shipyards & Ports: In shipbuilding, large bridge cranes (often 50–100t) assemble hull sections and move engines. Yuantai's bridge crane for shipyard solutions include corrosion-resistant paint and, if needed, end trucks for different rail layouts.
- Power Plants: Power plants and turbine shops use heavy-duty cranes for generator stators, turbines, and boilers. Typical lifts range 30–100t, matching Yuantai's range. Cranes in these plants often run continuously and must meet high safety standards.
- Mining & Minerals: Overhead cranes handle crushers, mining equipment, and ore bins. Explosion-proof versions (with flameproof motors and spark-free wheels) are used in coal or chemical environments.
- Construction & Heavy Manufacturing: Large machinery assembly (presses, extruders, heavy vehicles) often requires 30–60t cranes for installation. Yuantai cranes are used in fabrication facilities and warehouses for this reason.
- Others: Paper plants, railway, petrochemical and general industrial workshops also employ heavy overhead cranes. In any heavy-lifting scenario – from cleaning up scrap yards with a 40t grab crane to placing transformer coils with a 100t crane – these products are essential.
In each industry, the key is matching the crane to the task. Yuantai's broad model options (standard EOT, grab, magnet, ladle, explosion-proof) mean that customers get a solution "optimized for their workflow". For example, a steel mill needing fast scrap handling might choose a 60t double-girder grab crane, while a shipyard might prefer a high-lift 100t double-girder EOT crane.
Yuantai vs. General Market
Yuantai's heavy-duty cranes are comparable to international offerings in design and performance. As noted, Yuantai designs follow international standards (FEM, ISO) and the company holds CE and ISO9001 certifications. This means the cranes' core features (FEM A-class frames, modern drives, safety devices) match global best practices. For example, like other suppliers, Yuantai uses frequency-controlled motors and modular design to reduce deadweight and power consumption.
Compared to general market options:
- Capacity Range: Many standard suppliers offer heavy cranes up to 320–500t. Yuantai not only covers 30–100t fully, but can go beyond (up to 550t) for extreme cases.
- Customization: Yuantai emphasizes tailor-made configurations. The company will adjust specifications (span, height, temperature, explosion-proofing) for site needs. This level of customization is on par with other crane OEMs but often with more flexible pricing.
- Quality Components: Yuantai sources or manufactures key parts (motors, gearboxes, control systems) from well-known brands or equivalent Chinese brands. This is similar to other global suppliers, ensuring reliability. For example, European-style hoists and drives are offered.
- Safety Standards: Just like famous brands, Yuantai integrates advanced safety controls (limit switches, interlocks, anti-collision sensors). We also offer similar "Safe Features" (sway control, microspeed, etc.) either standard or as options.
- Cost & Support: Yuantai, as a Chinese manufacturer, often provides cost-competitive pricing. We maintain global support with project engineering, installation guidance, and on-site training.
