1. Introduction

In today’s fast-paced industrial environments, efficient material handling is critical for productivity and safety. Underhung cranes offer a versatile lifting solution, particularly in facilities with space constraints or specialized workflow requirements. Unlike traditional top-running cranes, underhung cranes are mounted on the bottom flange of runway beams, maximizing vertical space and allowing for greater flexibility in layout design.

For businesses with unique operational demands, custom underhung cranes provide the perfect solution. Whether it’s handling delicate aerospace components, optimizing warehouse storage, or streamlining automotive assembly lines, a tailored crane system enhances efficiency and safety.

Dongqi Crane specializes in designing and manufacturing custom underhung cranes to meet the specific needs of various industries. With advanced engineering capabilities and a commitment to quality, Dongqi ensures that each crane is optimized for performance, durability, and cost-effectiveness.

2. What Are Underhung Cranes?

Definition and Working Principle

Underhung cranes, also known as under-running bridge cranes, operate on tracks suspended from the ceiling or supporting structure. The crane bridge moves along the bottom flange of the runway beams, while the hoist and trolley traverse the bridge to position loads precisely.

Key Components

• Bridge: The horizontal beam that moves along the runway.
• Trolley & Hoist: The mechanism that travels across the bridge to lift and transport loads.
• Runway Beams: The supporting structure that guides the crane’s movement.

Advantages Over Top-Running Cranes

• Space-Saving: Since they hang from the ceiling, they maximize floor space.
• Flexibility: Ideal for multi-crane systems and complex layouts.
• Cost-Effective: Lower installation and structural support requirements.

3. Why Choose Custom Underhung Cranes?

Standard cranes may not always meet the unique demands of modern industries. Custom underhung cranes offer:

• Adaptability to Facility Layouts: Tailored spans, heights, and runway configurations to fit constrained spaces.
• Specialized Load Handling: Adjustable speeds, precision controls, and automation for delicate or heavy loads.
• Industry-Specific Solutions: Customizations for automotive, aerospace, warehousing, and more.
