Underslung Type Hoist for Double Girder Cranes

Underslung Double Girder Hoist Manufacturer – M V Engineering

The Underslung Type Hoist for Double Girder Cranes, manufactured by M V Engineering, is a highly specialized lifting solution designed to maximize vertical space in industrial facilities. In a conventional double girder crane, the hoist (crab) runs on top of the bridge girders. In contrast, our Underslung Double Girder Hoist is suspended from and travels along the bottom flanges of the two parallel girders. This innovative "under-running" design significantly reduces the required clearance above the crane bridge, allowing for maximum hook path and lifting height in buildings with low roofs or obstructing overhead structures.

Manufactured using premium-grade raw materials and advanced engineering, this hoist combines the exceptional load stability of a double girder configuration with the space-saving benefits of an underslung design. The hoist unit spans the gap between the two girders, distributing the load evenly across both bottom flanges to ensure smooth, vibration-free travel. Equipped with a heavy-duty electric motor, a precision-machined gearbox, a deep-grooved rope drum, and fail-safe electromagnetic brakes, this wire rope hoist delivers uncompromising performance under continuous industrial use.

Available in load capacities ranging from 1 Ton up to 20 Tons, the Underslung Type Hoist is ideal for manufacturing plants, heavy fabrication units, and assembly lines where overhead space is at a premium but heavy-duty lifting is essential. M V Engineering custom-designs the wheel assemblies and trolley span to perfectly match your specific girder dimensions and track profiles.

Key Features

• Low Headroom Profile: Hangs below the girders to maximize hook height and utilize vertical workspace efficiently.

• Dual-Flange Travel: Specifically designed to run smoothly on the bottom flanges of two parallel girders.

• Heavy-Duty Construction: Built to withstand the rigorous demands of heavy industrial material handling.

• High-Performance Electric Motor: Delivers consistent, high-torque power for efficient lifting and traveling.

• Precision Gearbox: Fully enclosed, oil-lubricated gears ensure quiet operation and smooth power transmission.

• High-Tensile Steel Wire Rope: Provides maximum tensile strength, wear resistance, and operational safety.

• Electromagnetic Braking System: Ensures instant, reliable stopping power to prevent load slips.

• Custom Adjustable Span: Trolley mechanism is tailored to perfectly fit the center-to-center distance of your double girders.

  
  

Technical Specifications

Applications

The Underslung Double Girder Hoist is specifically beneficial for industries operating in buildings with low roof clearances or complex structural constraints, including:

• Automobile Assembly Lines

• Heavy Fabrication Workshops

• Warehouses with limited vertical space

• Steel Processing Centers

• Foundries and Forging Plants

• Aviation Hangars and Maintenance Facilities

• Machine Shops

• Textile and Paper Mills

Advantages

• Maximizes Lifting Height: Eliminates the need for top clearance, giving the hook a higher maximum reach compared to top-running crabs.

• Exceptional Load Stability: Being suspended between two girders prevents load swinging and twisting during heavy lifts.

• Space Optimization: Ideal for installing heavy-duty double girder cranes in existing, older buildings not originally designed for top-running overhead cranes.

• Smooth Operation: Four-wheel or eight-wheel trolley designs ensure balanced, frictionless travel along the girder flanges.

• Reduced Building Costs: Allows for lower building heights during the design phase without sacrificing crane capacity.

Why Choose M V Engineering?

M V Engineering is a trusted manufacturer of advanced electric wire rope hoists, dedicated to solving complex material handling challenges. We understand that standard crane setups do not fit every building structure. Our Underslung Type Hoists for Double Girder systems are engineered specifically to adapt to your spatial limitations while maintaining uncompromising lifting strength.

Every hoist undergoes rigorous factory load testing to guarantee safety, flawless travel alignment, and long-term durability. We offer highly customized solutions, adjusting the hoist's trolley span, lifting speed, and headroom profile to seamlessly integrate into your existing or new double girder crane framework.

Frequently Asked Questions

What is an Underslung Double Girder Hoist? Unlike a standard double girder hoist (which sits on top of the crane bridge rails), an underslung hoist is suspended from and travels along the bottom flanges of the two bridge girders. It hangs between the girders.

Why choose an underslung hoist over a top-running crab? The primary reason is overhead space. If your facility has a low roof, HVAC ducting, or structural trusses that prevent a hoist from sitting on top of the crane, an underslung design tucks the hoist between and below the girders, maximizing your lifting height in confined spaces.

What capacities can this hoist handle? M V Engineering manufactures these specialized hoists for a wide range of capacities, typically starting from 1 Ton up to 20 Tons, depending on the structural strength of your girders.

Are these hoists safe for heavy-duty lifting? Yes. Because the hoist is suspended across two girders rather than a single monorail, the load weight is distributed evenly, providing exceptional stability and safety for heavy industrial applications.
