Product Description

Introducing the pinnacle of precision and safety in cargo lifting equipment: the High Safety Electric Control Cranes Cargo Lifting Equipment. Designed specifically for warehouse applications, these Double Beam Overhead Bridge Cranes ensure seamless operations and unmatched reliability.

Product Description

The Double Girder Overhead Crane epitomizes excellence in heavy-duty lifting solutions, tailored for the most demanding industrial settings. It boasts impressive lifting capacities, spanning capabilities, and precision load handling. Supported by two parallel main girders and end trucks, this crane guarantees unparalleled strength, stability, and adaptability compared to its single girder counterparts, making it the preferred choice for heavy industries and extensive operations.

Vantage1: Structural Design:
- Featuring two resilient main girders, available in box-type, truss, or custom-fabricated profiles, this design offers exceptional rigidity, significantly reducing deflection under hefty loads.
- Achieve superior hook height as the hoist is strategically positioned above the girders, optimizing your vertical workspace.
- Perfectly engineered for spans exceeding 30 meters, with capacities ranging impressively from 5 tons to over 500 tons.

Vantage2: Hoisting Mechanism:
- Equipped with robust wire rope or chain hoists from leading brands like Konecranes or ABUS, this mechanism is designed to tackle extreme load demands effortlessly.
- Offers optional auxiliary hoists to handle secondary lifting tasks, whether for maintenance or lighter loads, enhancing operational flexibility.

Vantage3: Driving System:
- Dual-drive motors installed on the bridge and trolley ensure smooth, synchronized movements, even when managing uneven loads.
- Cutting-edge frequency-controlled drives facilitate precise positioning while minimizing wear and tear, prolonging the system's lifespan.

Vantage4: Control & Safety
- Choose from multiple control options including pendant, radio remote, cabin-operated, or fully automated systems to best suit your needs.
- Comprehensive safety features include overload protection, anti-collision systems, emergency stops, and redundant braking to ensure maximum operational safety.

Application
1. Manufacturing Facilities: Perfectly suited for lifting and transporting heavy materials across manufacturing plants, assembly lines, and workshops.
2. Warehousing and Logistics: Expertly manages loading and unloading tasks within warehouses, distribution centers, and logistics hubs with ease.
3. Construction Sites: Delivers reliable lifting support for construction materials and equipment at various construction sites.
4. Power Plants: An indispensable asset for maintenance and installation tasks within power generation facilities, including thermal and hydroelectric power plants.
5. Shipbuilding and Ports: Essential for lifting and transporting heavy components in shipyards and ports, aiding in seamless shipbuilding and port operations.
