General purpose overhead crane
Heavy-Duty 150 Ton Double Girder Overhead Crane
Product Overview
The Weiyuan 150 Ton Double Girder Overhead Crane is a formidable heavy-duty lifting solution, engineered for the most demanding industrial applications. Designed for unparalleled strength, reliability, and precision, this crane is the backbone of operations in steel mills, heavy machinery manufacturing, power plants, and large-scale construction projects. Its robust double girder design allows for maximum hook height and superior stability when handling extreme loads. Equipped with an advanced electric hoist trolley, this crane delivers powerful, safe, and efficient performance, making it an essential asset for any facility managing super-heavy materials.
Product Advantages
Extreme Load Capacity and Stability
Engineered with two robust main girders, this crane provides exceptional structural integrity and rigidity. This design minimizes deflection and ensures maximum stability when lifting loads up to 150 tons, making it ideal for handling the heaviest and most critical materials safely.
High-Performance Hoisting Mechanism
The crane is equipped with a powerful electric hoist trolley that travels along rails on top of the girders. This system offers high lifting speeds, precise positioning, and long-term reliability, even under continuous, heavy-duty work cycles (A5-A8 work duty).
Optimized Workspace and Hook Height
The double girder configuration allows the hoist to be mounted between the girders, maximizing the available hook height. This is critical in facilities with limited vertical clearance, enabling you to lift loads higher and make better use of your workspace.
Advanced Safety and Control Systems
Safety is paramount. This crane is fitted with a comprehensive suite of safety features, including overload limiters, travel limit switches, emergency stop systems, and a durable braking system. The spacious operator cabin provides excellent visibility and advanced controls for precise and secure operation.
Durable, Long-Life Construction
Built with top-grade steel and components from world-renowned brands (e.g., Schneider, Siemens, ABB), the crane is designed for longevity in harsh industrial environments. Its surfaces are treated with a rigorous anti-corrosion process to ensure decades of reliable service.
Application Scenarios
Steel Mills and Foundries
Essential for handling ladles of molten metal, moving heavy steel coils, and loading finished products. Its robust construction and high-temperature resistance make it perfect for the extreme conditions of the steel industry.
Heavy Machinery and Equipment Manufacturing
Ideal for assembling large turbines, transformers, presses, and other massive industrial equipment. It provides the power and precision needed to lift and position multi-ton components safely.
Power Generation Plants
Used for critical maintenance tasks in nuclear and conventional power plants, such as lifting and positioning turbine rotors, generators, and other heavy equipment during installation or servicing.
Large-Scale Construction and Prefabrication Yards
Provides immense lifting power for handling large precast concrete segments, bridge sections, and heavy structural steel components in infrastructure projects.

FAQ
Q: What is the difference between a single girder and a double girder overhead crane?
A: A double girder crane uses two main beams, which makes it stronger and more stable, allowing for much higher lifting capacities (like 150 tons) and longer spans. A single girder crane is more economical and suitable for lighter loads, typically under 20 tons.
Q: What kind of environment is this 150-ton crane suitable for?
A: This crane is designed for heavy industrial environments. We can customize it for specific conditions, including high temperatures (foundry cranes), dusty atmospheres, or even explosive environments (explosion-proof cranes). Please specify your working conditions.
Q: What are the main components of the control system?
A: The standard configuration includes a comfortable, air-conditioned operator cabin with joystick controls for precise maneuvering. We also offer wireless remote control for added flexibility and safety, allowing the operator to manage the crane from the ground. The crane utilizes Variable Frequency Drives (VFDs) for smooth acceleration and deceleration of all movements.
Q: What information do I need to provide to get a quote?
A: To provide an accurate quote, we need to know the required lifting capacity (150 tons), the span (the width of your workshop), the lifting height (from the ground to the hook), your power supply details, and a description of the material being lifted and the working environment.
Q: How does Weiyuan ensure the quality and safety of such a large crane?
A: As a leading manufacturer with nearly 40 years of experience, Weiyuan follows strict international quality standards (ISO). Every 150-ton crane is designed by a team of expert engineers, built with certified steel, and undergoes rigorous non-destructive testing (NDT) on all welds. A full load test is performed before shipment, and we provide a complete set of quality assurance documents to guarantee its safety and performance.
