What Are Underhung Cranes? Types, Applications, and Benefits

Understanding Underhung Cranes: Key Features and Design Principles

What is an Underhung Crane

Underhung cranes, sometimes called under-running cranes, are a variety of overhead crane built to travel along the bottom flange of a runway beam. Unlike top-running cranes, which demand robust support frameworks, underhung cranes hang from the ceiling or pre-existing overhead beams. This setup makes them a smart option for places needing to make the most of vertical room. Their structure permits smooth, accurate motion throughout a facility. They don’t require large columns or floor tracks, which clears up precious workspace.

Unique Structural Components

The strength and performance of underhung cranes depend on several vital parts. The end trucks hold the wheels and enable motion along the runway beam. These are crafted to run on the beam’s lower flange, cutting down on wear to the setup. The hoist and trolley system lifts and moves loads. It’s small and light, adding to the system’s space-saving perk.

Runway beams are key for keeping things steady. Their light build reduces strain on the building’s ceiling. Unlike top-running cranes that put heavy pressure on their supports, underhung cranes spread weight more evenly. This cuts the need for major strengthening. The design frees up floor area. Businesses can add more workstations, storage shelves, or machines without crane supports getting in the way.

Types of Underhung Cranes: Choosing the Right Configuration

Single-Girder Underhung Cranes

Single-girder underhung cranes suit light to medium tasks, usually managing loads from 1 to 10 tons. You’ll find them in workshops, assembly lines, and small storage spaces where tight areas need efficient material handling. Their single-girder setup keeps weight and cost low. Yet, it still offers enough lift power for many industrial jobs.

These cranes bring big perks during setup. They can attach to existing ceiling beams without extra supports. This proves handy for places needing occasional tweaks or growth.

Double-Girder Underhung Cranes

For jobs needing higher load limits and wider spans, double-girder underhung cranes offer extra toughness and balance. They can lift 10 to 20+ tons. Industries like car-making, aerospace, and heavy equipment production often use them.

The two-girder design boosts hook height. Loads can rise higher without needing more clearance. This helps in fields moving big or heavy parts smoothly while keeping exact placement. The added power also supports advanced options like automated controls, synced lifting, and multi-crane setups for very large loads.

Modular and Customizable Underhung Systems

Today’s manufacturing and shipping settings often need adaptable material handling tools. Modular underhung crane systems let companies tailor their setup to fit specific needs. They might add curved tracks, extra hoists, or multi-crane layouts. These options boost efficiency and flexibility.

Nante Crane, a top maker in China, excels in customizable underhung cranes for diverse industry needs. Their products blend smoothly into current setups, cutting downtime and improving workflow.

Key Applications of Underhung Cranes Across Industries

Manufacturing and Assembly Lines

Underhung cranes shine in manufacturing and assembly tasks needing exact part movement. In car and electronics fields, they move fragile or hefty items between stations with ease. This lowers damage risks and boosts work speed. Their skill in tight spaces fits complex assembly jobs perfectly.

Warehousing and Logistics

Good storage and pickup matter in warehouses where space is key. Underhung cranes improve material handling by moving goods smoothly. They don’t block aisles or shrink floor room. Their compact build lets forklifts and other gear work freely without crane supports in the way.

Food and Beverage Processing

The food and drink sector has strict cleanliness rules needing special handling tools. Underhung cranes can use rust-proof materials like stainless steel to meet safety standards. Their design cuts contamination risks while moving raw goods and final products efficiently.

Aerospace and Heavy Machinery

In aerospace and heavy equipment fields, underhung cranes handle oversized, delicate parts. Their precise load control lowers damage risks to costly, sensitive gear. Plus, their flexible design safely moves odd-shaped items that standard cranes might struggle with.

Advantages of Underhung Cranes: Why They Outperform Alternatives

Space Optimization and Layout Flexibility

Unlike top-running cranes needing extra supports, underhung cranes make the most of available workspace. Their ceiling-hung design lets firms use floor space better for production, storage, or extra stations.

Energy Efficiency and Reduced Infrastructure Costs&nbsp

The light build of underhung cranes means less energy use compared to heavier top-running types. Also, the lower structural strain cuts the need for big building changes. This leads to cheaper overall setup costs.

Enhanced Safety and Precision

Underhung cranes offer steady load handling, reducing sway and ensuring safe material shifts. This matters in fields needing exact placement of heavy or fragile parts. Their user-friendly design improves operator control and workplace safety.

Scalability for Future Expansion

Firms planning growth can gain from underhung cranes’ modularity. These systems upgrade easily with added hoists, automation, or longer runways to meet rising production needs.

How to Select the Right Underhung Crane for Your Facility

Assessing Load Capacity and Span Requirements

Knowing current and future load needs is vital when picking an underhung crane. Firms should check the weight and size of items they move often. They should also think about possible growth.

Environmental and Operational Factors

Places in tough settings must pick rust-proof materials for lasting use. Also, noise-cutting features can help indoor work, boosting worker ease and meeting safety rules.

Automation and Smart Technology Integration

Modern underhung cranes can include high-tech automation like remote tracking, crash prevention, and upkeep prediction tools. These upgrades lift efficiency and lower running costs.
