General purpose overhead crane
Top-Selling LH Type Double Girder EOT Crane 5–50 Ton | Workshop Optimized, CE-Compliant
Product Overview
The LH Type Double Girder Electric Overhead Travelling (EOT) Crane is a top-selling, high-performance lifting solution that combines the strength of a double-girder bridge with the economy of a standard hoist trolley. Designed for medium to heavy-duty workshop applications, this crane offers capacities from 5 to 50 tons. It features a robust double-beam structure supporting a high-quality CD/MD hoist trolley or a compact open winch, providing enhanced lifting height and stability compared to single-girder models. It is the perfect choice for factories and manufacturing plants that require reliable, high-capacity lifting.
Product Advantages
- Enhanced Stability and Capacity: The double-girder design provides excellent torsional rigidity and stability, allowing for safer handling of heavier and wider loads compared to single-girder cranes.
- Cost-Effective Double Girder Solution: The LH model offers the strength and performance of a double-girder crane at a more accessible price point by utilizing standardized hoist components, delivering an excellent return on investment.
- Improved Lifting Height: The hoist trolley runs on top of the two main girders, providing a better hook height than a standard under-running single-girder crane, which is ideal for facilities that need to maximize vertical space.
- Proven and Reliable Performance: Engineered for A5 work duty and equipped with industry-proven hoist and travel components, this crane is built for durable, long-term performance in demanding industrial environments.
- Versatile and Customizable: Fully adaptable to your workshop’s needs, with customizable span, capacity, and control options. It can be equipped with various below-the-hook devices for different material handling tasks.
Application Scenarios
- Heavy Manufacturing and Assembly: An ideal workhorse for lifting large fabrications, heavy machinery, and major components in steel plants, automotive factories, and heavy equipment assembly lines.
- Machine Shops and Tooling: Perfectly suited for handling heavy dies, molds, and large workpieces, enabling efficient loading and unloading of heavy-duty machinery.
- Warehouse and Indoor Storage: Provides powerful lifting for moving heavy coils, pallets, and oversized inventory in large-scale storage and distribution centers.
- Paper Mills and Processing Plants: Reliably handles heavy paper rolls, raw materials, and finished goods, withstanding the demands of continuous operation.
- Power Plants and Maintenance Bays: A trusted solution for lifting turbines, generators, pumps, and other heavy equipment during installation and maintenance operations.
