Bridge Cranes (Overhead Cranes)

Bridge cranes — also called overhead cranes — are the most widely used industrial crane type. They have one or two horizontal bridge girders that travel along elevated runway rails, with a hoist and trolley moving across the bridge. The crane runs inside a building envelope, using the building’s structural supports.

Single Girder Overhead Crane

Configuration: One bridge girder with the hoist trolley traveling on the bottom flange or a trolley rail mounted below the girder.

Capacity range: 0.5 tons to 20 tons

Span range: 7.5 meters to 31.5 meters

Duty class: FEM 1Am–2m / CMAA Class B–C

Key characteristics:

• Lower initial cost than double-girder designs
• Lighter structure reduces building steel requirements
• Hook height is reduced (trolley hangs below the girder)
• Suited for lighter duty cycles and shorter spans

Typical applications: Machine shops, assembly lines, warehouses, light manufacturing, maintenance bays

Our European-type electric single-girder overhead cranes at Yuzhong Crane feature optimized box-section girders, integrated VFD-controlled travel, and European-standard electric hoists with C-type reducers — better positioning accuracy and energy efficiency than conventional designs.

Double Girder Overhead Crane

Configuration: Two bridge girders with the hoist trolley traveling on rails mounted on top of the girders.

Capacity range: 5 tons to 500+ tons

Span range: 10.5 meters to 40+ meters

Duty class: FEM 2m–5m / CMAA Class C–F

Key characteristics:

• Higher load capacity than single-girder designs
• Superior hook height (trolley rides on top of girders, adding girder depth to lift height)
• Can handle multiple hoists on the same bridge
• Better for heavy-duty and severe-duty cycles
• Allows a maintenance walkway between girders

Typical applications: Steel mills, foundries, heavy fabrication, paper mills, power generation facilities, heavy machinery manufacturing

Design variants:

• Standard double-girder: Box girder construction with welded or bolted connections
• European-type (low-headroom): Compact design with reduced building height requirements
• Ladle crane: Specialized variant with dual hoists for molten metal handling in steel mills
• Insulation crane: Features electrical isolation for aluminum smelting operations

Under-Hung (Under-Running) Bridge Crane

Configuration: Bridge girders run on the bottom flange of the runway beams. The trolley and hoist hang below the bridge.

Capacity range: 0.5 tons to 15 tons

Span range: 3 meters to 18 meters

Key characteristics:

• Can be configured as single-girder or double-girder
• Maximizes usable hook height
• Runway beams are typically suspended from the building roof structure
• Often used for shorter spans and lighter loads
• Can transfer loads between bays using a monorail system

Typical applications: Light assembly, clean rooms, maintenance areas, storage facilities with low headroom requirements

Gantry Cranes

Gantry cranes are similar to bridge cranes but have legs that support the bridge girders on rails at ground level (or on elevated runways). No building structural supports needed — that makes them ideal for outdoor use and facilities without overhead runway support.

Full Gantry Crane (Double Leg Gantry)

Configuration: Two legs support the bridge girder(s), with legs traveling on ground-level rails.

Capacity range: 5 tons to 500+ tons

Span range: 10 meters to 60+ meters

Duty class: FEM 1Am–5m / CMAA Class A–F

Key characteristics:

• Self-supporting structure — no building support required
• Built for outdoor applications exposed to weather
• Can have one or both legs with cantilever arms for extended reach
• Available with rubber-tired (RTG) or rail-mounted (RMG) travel systems

Typical applications: Container terminals, lumber yards, scrap yards, shipyards, precast concrete plants, steel stockyards

Our MG series general-purpose gantry cranes at Yuzhong Crane cover 5 to 500 tons — solid box-girder construction, weatherproof electrical systems, and optional remote control for harsh outdoor environments.

Semi-Gantry Crane

Configuration: One leg supports one end of the bridge girder on a ground-level rail. The other end rides on an elevated runway beam mounted on the building structure.

Capacity range: 2 tons to 50 tons

Span range: 5 meters to 25 meters

Key characteristics:

• Hybrid design — part gantry, part bridge crane
• More economical than a full gantry when one side can use building support
• Useful for facilities with partial outdoor storage
• Cuts building steel requirements compared to a full double-girder bridge crane

Typical applications: Outdoor storage next to buildings, fabrication yards, material laydown areas

Portable Gantry Crane (A-Frame Gantry)

Configuration: Lightweight, freestanding frame with adjustable or fixed legs on casters or fixed feet.

Capacity range: 0.25 tons to 5 tons

Typical applications: Heavy workstations, foundry operations, areas needing maximum jib crane capacity

—

Wall-Traveling Cranes (Wall Cranes)

Wall-traveling cranes are bridge cranes where the bridge girders mount directly on the building walls (or wall-mounted rails) — no separate runway beams. The bridge travels along the wall rails.

Capacity range: 1 ton to 20 tons

Span range: 8 meters to 25 meters

Key characteristics:

• Eliminates separate runway beams — saves money
• Building walls must be strong enough to support crane loads
• Limited to buildings with suitable wall construction
• Common in older facilities where runway beam installation is impractical

How to Choose the Right Industrial Crane

So how do you pick the best crane type? Let us break it down.

Step 1: Define Your Load Requirements

• Maximum load weight: Include lifting beams, spreaders, magnets, or grabs — not just the raw product weight
• Load dimensions: Length, width, and height affect hook height and trolley design
• Load center of gravity: Eccentric loads need specialized lifting attachments
• Load frequency: How many lifts per hour? This sets the duty class

Step 2: Determine the Operating Environment

• Indoor or outdoor: Outdoor needs gantry cranes or weatherized bridge cranes
• Temperature: Extreme heat (foundries) calls for metallurgical-grade cranes
• Hazardous atmosphere: Explosive gases or dust? You need ATEX/IECEx certified cranes
• Corrosive environment: Chemical plants and marine settings need special coatings and materials
• Clean room: Semiconductor and pharma applications need stainless steel or coated components

Step 3: Calculate Required Coverage

• Span: Distance the crane must cover across the working area (perpendicular to travel direction)
• Length of travel: Distance along the runway (parallel to travel direction)
• Hook height: Required lift height from ground to highest hook position
• Coverage shape: Rectangular (bridge/gantry), circular (jib), or linear (monorail)

Step 4: Select the Duty Class

Match the crane’s duty class to your actual usage:

Step 5: Think About Future Needs

• Capacity expansion: Will loads get heavier? Consider oversizing the structure now
• Automation readiness: Planning for automation later? Specify VFD controls, encoder feedback, and communication interfaces today
• Facility expansion: If the building might grow, choose crane designs that can be extended

Frequently Asked Questions (FAQ)

Q1: What is the most common type of industrial crane used in factories?

In heavy industrial factories (steel mills, foundries, heavy fabrication), the double-girder overhead crane is the go-to. For light and medium-duty manufacturing (machine shops, assembly plants, warehouses), the single-girder overhead crane dominates. The choice comes down to load capacity (single-girder handles up to 20 tons; double-girder covers 5 tons and up when you need more hook height or heavier duty), the available building structure, and the duty cycle. For most general manufacturing, a European-type single-girder crane gives you the best mix of cost, performance, and maintainability.

Q2: What is the difference between a bridge crane and a gantry crane?

It comes down to support. A bridge (overhead) crane has its bridge girders held up by runway beams attached to the building’s columns or roof — it works inside the building envelope. A gantry crane has its bridge girders supported by legs sitting on ground-level rails or wheels — self-supporting, no building structure needed. Bridge cranes are typically indoor (where building support exists). Gantry cranes work outdoors (yards, ports, shipyards) or in buildings where the structure cannot handle crane loads.

Q3: How do I determine what crane capacity I need?

Start with the heaviest load you need to lift — including all lifting accessories (spreader beams, lifting beams, magnets, grabs, vacuum lifters). Never pick a crane rated exactly at your max weight. Leave at least 15–20% margin above the heaviest planned lift. And think ahead — will future operations need more capacity? If your heaviest current load is 18 tons with rigging, a 20-ton crane works today, but a 25-ton crane gives you room to grow. The Yuzhong Crane engineering team can help calculate the right capacity for your specific lifting scenarios.

Q4: What is the difference between single-girder and double-girder overhead cranes?

Single-girder cranes have one bridge girder — the hoist trolley runs on the bottom flange. They are lighter, cheaper, and good for capacities up to 20 tons with lighter duty cycles. Double-girder cranes have two bridge girders — the trolley runs on top. They handle higher capacities (5–500+ tons), give greater hook height (trolley sits above the girders, so you gain girder depth in lift height), support multiple hoists, and suit heavy-duty cycles (FEM 3m–5m). General rule: single-girder for light-to-moderate duty up to 20 tons; double-girder for heavier loads, taller hook heights, or tougher duty cycles.

Q5: Can a gantry crane be used indoors?

Yes, in several situations: (1) the building structure cannot support an overhead bridge crane (weak columns or insufficient roof height), (2) the crane needs to serve both indoor and outdoor areas (semi-gantry setup), (3) very large facilities like aircraft assembly hangars where the span exceeds practical bridge crane designs, or (4) temporary or relocatable installations (portable gantry cranes). That said, for standard indoor use with adequate building structure, bridge cranes are usually more cost-effective and space-efficient.

Q6: What is the expected service life of an industrial crane?

Depends on duty class, maintenance quality, and operating environment. A well-maintained crane built to FEM 3m (moderate-heavy) duty class typically has a design life of 25–30 years — roughly 200,000–400,000 operating hours. Cranes in FEM 5m (continuous severe service) may have a shorter structural life of 15–20 years due to higher fatigue loading. Light-duty cranes (FEM 1Am) with great maintenance can exceed 40 years. Mechanical parts (wire ropes, brakes, bearings, contactors) get replaced periodically throughout the crane’s life, but the primary structural members (bridge girders, end trucks, legs) generally last the full design life when properly maintained. Regular inspections, timely component replacement, and quick repair of any structural damage — that is how you maximize crane service life.
