The LH Series Electric Hoist Double Girder Overhead Crane is engineered for efficient light to medium-duty material handling. It offers a reliable solution for lifting and positioning goods in diverse settings such as manufacturing plants, assembly workshops, warehouses, and storage yards. This model is ideal for applications that do not require continuous, all-day operation.

Constructed from high-strength steel, the crane's primary components include rigid double girders, robust end trucks equipped with travel drive mechanisms, and a dedicated electric hoist trolley for precise load handling. An integrated maintenance platform facilitates easy service access. Available in capacities from 3 to 20 tons and spans from 10.5 to 31.5 meters, this crane is customizable in color to meet your facility's specifications. Its compact design maximizes the utilization of existing building space and can help reduce structural support costs. Under specific, non-intensive usage conditions, it can occasionally handle loads slightly above its rated capacity.

Key Features & Advantages:

• Space-Efficient Design: Features low building clearance and minimized wheel load, reducing the strain on your facility's structure.

• Robust Construction: A rational structural design ensures exceptional rigidity and long-term operational stability.

• Flexible Control & Smooth Operation: Offers variable speed control through frequency inverter technology. Control is available via a pendant station, enclosed cab, or remote control for operator convenience.

• Simplified Installation & Maintenance: Designed for straightforward setup and easy ongoing maintenance.

• Comprehensive Safety Systems: Manufactured in compliance with ISO standards and includes multiple safety devices:

• Load Limiter & Weight Overload Protection

• Emergency Stop Buttons

• Travel Limit Switches (Long & Cross)

• Electrical Protections: Phase Loss, Incorrect Phase Sequence, Over-Current, Short-Circuit, Undervoltage, and Zero-Position Protection

• High-IP Enclosures (IP44/IP54/IP55) for dust and water resistance

• Anti-Drop Safety Latches on Hooks

• Polyurethane Buffers to absorb travel impact

• Audible/Visual Travel Alarms

• Optional rain covers for outdoor applications.

Engineered for precision, durability, and superior load management, our LH-Type Electric Hoist Double Girder Bridge Crane is the industrial-grade solution for your demanding lifting applications. Designed in compliance with mechanical industry standards (including JB/T 3695-2008, Type Q10406), this crane combines robust construction with advanced remote-control operation for unmatched efficiency and safety in workshop, warehouse, and production line environments.

Core Design & Unmatched Advantages

This overhead traveling crane features a dual-girder (double beam) structure for exceptional strength and rigidity, supporting the electric hoist that travels seamlessly along the bridge. The "LH" designation stands for "L" (Beam-type) and "H" (Hoist), precisely defining its efficient design.

• Enhanced Stability & Load Capacity: The double girder design provides a more stable lifting path and higher hook height compared to single girder cranes, ideal for heavy-duty cycles and precise load positioning.

• Superior Control with Remote Operation: Gain complete command from a safe, convenient distance. Our specialized industrial remote control system offers stable, responsive, and intuitive operation for lifting, traversing, and traveling motions.

• Built for Reliability & Ease of Maintenance: Constructed with high-quality components, including a durable wire rope hoist, powerful drive motors, and resilient wheels. Key maintenance points, such as the gearbox, brakes, and wire rope, are designed for accessibility, ensuring long service life and minimal downtime.

Expert-Recommended Features for Optimal Performance

Our cranes integrate operational best practices directly into their design and recommended use:

• Enhanced Precision & Control: Achieve "steady, accurate, and fast" handling. Smooth acceleration/deceleration minimizes load swing, while precise controls allow for millimeter-accurate positioning and "micro-motion" for delicate operations.

• Proactive Safety & Protection Systems: We equip our cranes with critical safety devices including:

• Overload Limiters to prevent hazardous overloads.

• Travel Limit Switches for bridge and trolley.

• Emergency Stop Functions.

• High-Quality Braking Systems for secure holding.

• Insulated components and other safety features in the electrical system.

• Engineered for Safety: Adheres to fundamental safety protocols. The design incorporates safety door switches, "zero-position" start protection, and failsafe measures to protect both personnel and assets.

Robust Construction & Key Components

• Bridge Framework: High-strength welded steel structure (box girder or truss design) for maximum integrity.

• Hoist Unit: Reliable electric wire rope hoist as the primary lifting mechanism.

• Travel System: Separate drive systems for the bridge (long travel) and trolley (cross travel), featuring motors, brakes, and wheels.

• Electrical System: Enclosed panel with quality contactors, controllers, and variable frequency drives (VFD options available) for smooth operation.

Ideal For:

Heavy manufacturing, steel service centers, large warehouse logistics, paper mills, power stations, and any facility requiring reliable, high-capacity overhead lifting with the flexibility of remote control.
