Product Description

Introducing our High-Safety Electric Control Cranes: the epitome of cargo lifting excellence. Engineered as Double Beam Overhead Bridge Cranes, these are perfect for warehouse environments, combining unyielding safety with efficient performance.

Product Description

Our double girder overhead crane is the ultimate heavy-duty lifting solution, meticulously designed for intense industrial settings where lifting high capacities, spanning vast distances, and executing precise load handling are paramount. Featuring two robust parallel main girders supported by durable end trucks, this crane stands as a testament to superior strength, stability, and flexibility. It surpasses single girder designs, making it indispensable for heavy industries and extensive operations.

Vantage1: Structural Design:
- Engineered with two formidable main girders, available as box-type, truss, or expertly fabricated profiles, offering outstanding rigidity and minimizing deflection even under the heaviest loads.
- Enjoy an elevated hook height as the hoist is strategically mounted *above* the girders, maximizing vertical workspace for enhanced efficiency.
- Expertly crafted to accommodate spans beyond **30 meters** and handle capacities from **5 tons to an impressive 500+ tons**.

Vantage2: Hoisting Mechanism:
- Outfitted with industrial-grade wire rope or chain hoists, such as those from Konecranes or ABUS, capable of lifting the most extreme loads with ease.
- Optional auxiliary hoists available for secondary lifting tasks, seamlessly handling maintenance or lighter load requirements.

Vantage3: Driving System:
- Dual-drive motors on both the bridge and trolley deliver smooth, synchronized movement, even when managing uneven loads.
- State-of-the-art frequency-controlled drives provide precise positioning and significantly reduce wear and tear, ensuring longevity.

Vantage4: Control & Safety
- Offers a variety of control options: pendant control, radio remote systems, cabin-operated modes, or fully automated systems for the ultimate in versatility and convenience.
- Comprehensive safety features include overload protection, anti-collision systems, emergency stop functions, and redundant braking mechanisms for unparalleled safety.

Application
