General purpose overhead crane
LH Type Double Girder Overhead Crane 5–32 Ton | Workshop Duty, High Stability, CE-Compliant
Product Overview
The LH Type Double Girder Overhead Crane is a robust and efficient lifting solution engineered specifically for workshop applications. It provides the superior strength and stability of a double-girder design while maintaining a compact profile, making it a significant upgrade over single-girder cranes for handling heavier loads. With typical capacities from 5 to 32 tons, this crane utilizes a standard CD/MD hoist trolley or a compact open winch running on top of the bridge beams. This configuration provides excellent lifting height and reliable performance for demanding industrial environments like manufacturing plants, machine shops, and assembly bays.
Product Advantages
- Superior Stability: The dual-girder structure offers exceptional torsional rigidity, significantly reducing sway and providing a more stable platform for lifting and transporting heavy or bulky loads safely.
- Increased Lifting Height: By placing the hoist trolley on top of the girders, the LH model achieves a greater hook height compared to an equivalent under-running single-girder crane, maximizing the vertical space in your workshop.
- Cost-Effective Heavy Lifting: This crane delivers the performance advantages of a double-girder system at a highly competitive price point by using standardized, readily available hoist trolley components.
- Durable and Reliable: Designed for A5 medium-duty work cycles, the LH crane is built with high-strength steel and proven components to ensure long-term durability and dependable operation in busy workshop environments.
- Enhanced Versatility: The strong, stable platform is ideal for adding various attachments, such as magnets, grabs, or turning devices, and it allows for true vertical lifts without the hook drift common in single-girder hoist designs.
Application Scenarios
- Manufacturing and Fabrication: A perfect workhorse for moving large fabrications, heavy steel plates, and machinery components with precision and stability in busy production areas.
- Machine Shops: Ideal for safely handling heavy molds, dies, and large workpieces, enabling efficient loading and positioning on heavy-duty CNC machines and presses.
- Assembly Plants: Provides the power and control needed to lift and assemble major components, such as engines, chassis, and heavy equipment frames.
- Maintenance Workshops: A reliable choice for lifting heavy industrial equipment, motors, and gearboxes for service, repair, and overhaul operations.
- Indoor Storage and Warehousing: Effectively handles heavy coils, structural steel bundles, and other oversized inventory in large-scale storage facilities.
