Gantry crane
High-Quality Gantry Crane for Heavy Lifting
Product Overview
The Weiyuan 150t Electric Hoist Beam Crane is a heavy-duty lifting powerhouse, engineered for the most demanding industrial applications. This overhead crane, often referred to as a double-girder bridge crane, is designed to provide maximum strength, stability, and reliability for handling extreme loads up to 150 tons. It is the definitive solution for steel mills, heavy manufacturing plants, power generation facilities, and large-scale assembly operations. Equipped with a robust electric hoist trolley and built with premium materials, this crane delivers superior performance, enhances operational safety, and maximizes productivity for your most critical lifting tasks.
Product Advantages
Exceptional Strength and Stability
The double-girder box frame construction provides outstanding torsional rigidity and structural integrity. This design ensures minimal deflection and maximum stability, even when lifting massive 150-ton loads, making it significantly safer and more reliable than single-girder alternatives for heavy-duty applications.
Optimized Lifting Height
By positioning the electric hoist trolley to run on top of the two girders, this crane achieves a superior lifting height. This feature is crucial in facilities with limited headroom or where maximizing vertical clearance is necessary to handle oversized components.
High-Performance and Precision Control
Powered by a heavy-duty electric hoist and advanced motor systems, this crane offers powerful and smooth operation. The inclusion of Variable Frequency Drives (VFDs) provides precise, stepless control over all movements, reducing load swing and allowing for the accurate and safe positioning of critical components.
Engineered for Durability and Longevity
Constructed from high-grade Q345B steel and equipped with world-class components from brands like Siemens and Schneider, this crane is built for A6-A8 heavy-duty work cycles. Its robust design ensures a long service life with minimal maintenance, even in the harshest industrial environments.
Comprehensive Safety Systems
Safety is our top priority. The crane is equipped with a full suite of advanced safety features, including overload protection limiters, emergency stop systems, dual travel limit switches, and a high-performance braking system, to ensure fail-safe operation at all times.
Application Scenarios
Steel Mills and Foundries
Essential for handling ladles of molten metal, massive steel coils, and heavy slabs. Its robust design is built to withstand the high temperatures and demanding operational pace of the steel industry.
Heavy Machinery and Equipment Manufacturing
Ideal for lifting and assembling large turbines, generators, presses, and other multi-ton industrial machinery. Its precision control is critical for complex and delicate assembly processes.
Power Generation and Energy Sector
An indispensable tool for installation and maintenance in nuclear and conventional power plants. It is used to safely lift and position heavy components like turbine rotors and transformers.
Shipbuilding and Large-Scale Construction
Provides immense lifting power for moving large ship sections, heavy prefabricated modules, and structural steel components in shipyards and major infrastructure projects.

FAQ
Q: When is a 150-ton double-girder crane the right choice?
A: A 150-ton double-girder crane is necessary for applications involving extremely heavy loads that are beyond the capacity of standard cranes. It is the premier choice for sectors like heavy manufacturing, steel production, power generation, and major construction projects where strength and stability are non-negotiable.
Q: What is the difference between a hoist trolley and a winch trolley for a crane this size?
A: For a 150-ton capacity, a heavy-duty winch trolley is typically used. A winch trolley is custom-built for very high capacities, faster lifting speeds, and severe duty cycles (A6-A8). It is more robust and offers easier maintenance access compared to a standard hoist trolley.
Q: What are the requirements for installing such a large crane?
A: This crane runs on an elevated runway system supported by your building’s columns or an independent steel structure. A certified structural engineer must verify that the building and foundation can safely support the immense loads from the crane and its 150-ton capacity. We provide all necessary wheel load data for this critical evaluation.
Q: Can this crane be operated in harsh environmental conditions?
A: Yes. We can customize the crane for a wide range of challenging environments. This includes special high-temperature configurations for foundries, corrosion-resistant paint and materials for coastal areas, and spark-proof designs for potentially explosive atmospheres.
Q: How does Weiyuan ensure the quality and safety of a 150-ton crane?
A: With nearly 40 years of manufacturing excellence, Weiyuan operates under a strict ISO-certified quality management system. Every 150-ton crane is meticulously designed by our expert engineering team, fabricated from certified high-strength steel, and subjected to rigorous non-destructive testing on all welds. Before shipment, a full load test is conducted to guarantee it meets and exceeds all international safety and performance standards.
