An overhead bridge crane is a heavy-duty material handling equipment designed to lift, przenosić, and position large or heavy loads horizontally across a fixed span. Suspended from or mounted on elevated runways (typically along the length of a facility), it consists of a bridge structure that travels along these runways, with a hoist or trolley system that moves perpendicular to the bridge—enabling precise, multi-directional load movement.

Widely used in industrial settings, overhead bridge cranes streamline operations, reduce manual labor, and enhance safety when handling weights from a few tons to hundreds of tons. They are customizable to fit specific workspace dimensions, load requirements, i warunki środowiskowe, making them indispensable in manufacturing, logistyka, and heavy industries.

Key Features of Overhead Bridge Cranes

Suwnica mostowa

Overhead bridge cranes are engineered for reliability, efektywność, i bezpieczeństwo. Here are their core features:

1. Wysoka ładowność: Designed to handle loads ranging from 1 ton to over 500 mnóstwo, suitable for light to ultra-heavy lifting tasks.
2. Precyzyjna kontrola: Equipped with advanced hoist and trolley systems (podręcznik, elektryczny, or hydraulic) for smooth, accurate load positioning—critical for delicate operations like machinery assembly.
3. Trwała konstrukcja: Built with high-strength steel girders, reinforced runways, and corrosion-resistant components to withstand harsh environments (NP., wysokie temperatury, pył, or humidity).
4. Zgodność z bezpieczeństwem: Zintegrowane funkcje bezpieczeństwa obejmują ochronę przed przeciążeniem, przyciski zatrzymania awaryjnego, wyłączniki krańcowe, and anti-collision systems, meeting global standards (OSHA, ISO, Fem).
5. Wydajność kosmiczna: Operates above ground level, freeing up floor space for other equipment or workflows—ideal for facilities with limited ground area.
6. Customizability: Available in single or double girder designs, with options for span length, wysokość podnoszenia, power sources (elektryczny, diesel), and automation (for unmanned operations).

Pojedynczy dźwigar vs.. Double Girder Overhead Bridge Cranes: What’s the Difference?

Single girder overhead bridge crane

Double girder overhead bridge crane

Double girder overhead crane

Choosing between single girder and double girder overhead bridge cranes depends on your load requirements, workspace, and budget. Here’s a breakdown:

Funkcja	Single Girder Overhead Bridge Crane	Double Girder Overhead Bridge Crane
Structure	One main girder (beam) supporting the hoist/trolley.	Two parallel girders with the hoist/trolley running between them.
Pojemność ładowania	Aż do 20 mnóstwo (standard); 50 mnóstwo (heavy-duty models).	20 tons and above (commonly 50–500+ tons).
Długość rozpiętości	Ideal for spans up to 30 metry.	Suitable for longer spans (aż do 50+ metry).
Wysokość podnoszenia	Moderate (limited by single girder strength).	Higher lifting heights (extra clearance due to dual girders).
Koszt	More affordable (simpler design, lower material use).	Wyższy koszt początkowy (sturdier build, larger components).
Najlepsze dla	Light to medium loads; small to medium facilities (NP., warsztaty, magazyny).	Heavy loads, large spans, or harsh environments (NP., Stalowe młyny, stoczni).

Technical Specifications of Overhead Bridge Cranes

Below is a general parameter table for common overhead bridge crane models. Custom specifications are available based on your needs:

Model Type	Max Lifting Capacity	Długość rozpiętości	Wysokość podnoszenia	Klasa robotnicza (ISO/FEM)*	Zasilacz	Prędkość podnoszenia
Pojedynczy dźwigar (Standard)	1–20 ton	5–30 m	3–12 m	A3–A5	380V/3 fazy/50 Hz (custom)	0.5–10 m/min
Pojedynczy dźwigar (Ciężka)	20–50 tons	10–25 m	5–15 m	A5–A6	380V/3 fazy/50 Hz (custom)	0.3–8 m/mnie
Podwójny dźwigar (Standard)	20–100 tons	10–40 m	6–20 m	A6–A7	380V/3 fazy/50 Hz (custom)	0.2–6 m/min
Podwójny dźwigar (Ultra-Heavy)	100–500+ ton	15–50+ m	8–30 m	A7–A8	Zwyczaj (diesel/electric)	0.1–4 m/min

Klasa robotnicza: Indicates duty cycle (how often the crane operates under load). Higher classes (A7–A8) suit continuous, heavy-use environments.

Industries That Use Overhead Bridge Cranes

Suwnice pomostowe

Overhead bridge cranes are versatile across sectors requiring heavy material handling. Key applications include:

1. Produkcja: Moving raw materials (stal, aluminum) and finished products on assembly lines (automobilowy, Aerospace, maszyneria).
2. Magazynowanie & Logistyka: Loading/unloading cargo, stacking pallets, and organizing inventory in distribution centers.
3. Metallurgy: Handling molten metal, wlewki, and rolled steel in foundries and steel mills.
4. Budowa: Lifting building materials (stalowe belki, panele betonowe) in prefabrication yards or on-site.
5. Górnictwo: Transporting ore, sprzęt, and components in mines or processing plants.
6. Okrętownictwo: Assembling large ship parts and moving heavy machinery in dry docks.
7. Zarządzanie odpadami: Handling bulk waste or recycling materials in treatment facilities.

How to Choose the Right Overhead Bridge Crane?

Suwnice pomostowe

Follow these steps to select the perfect overhead bridge crane for your needs:

1. Determine Load Requirements: Calculate the maximum weight you’ll lift (include margins for future needs) to choose between single (≤20 tons) or double (≥20 tons) girder models.
2. Measure Your Workspace: Check the span (distance between runways) and available headroom (wysokość podnoszenia) to ensure the crane fits.
3. Assess Working Conditions: Consider environmental factors—high temperatures, pył, or corrosive substances may require specialized coatings or components.
4. Evaluate Duty Cycle: Choose a working class (A3–A8) based on how often the crane will operate (NP., A7 for 24/7 heavy use).
5. Set a Budget: Single girder overhead cranes are more cost-effective for light tasks; double girder cranes are a long-term investment for heavy loads.
6. Prioritize Safety & Zgodność: Ensure the crane meets local regulations (NP., OSHA in the U.S., CE in the EU) and includes essential safety features.

FAQ: Suwnica mostowa

Q1: How often should an overhead bridge crane be inspected?

A: Daily visual checks (for wear, leaks, or loose parts) and annual professional inspections are mandatory. Heavy-use cranes (A7–A8) may require quarterly inspections.

Q2: Can overhead bridge cranes be automated?

A: Tak. Modern models can integrate with IoT systems for automated load tracking, scheduled movements, and remote operation—ideal for repetitive tasks.

Q3: What’s the lifespan of an overhead bridge crane?

A: With proper maintenance, single girder cranes last 15–20 years; double girder cranes can operate for 25–30 years or longer.

Q4: How is an overhead bridge crane installed?

A: Installation involves mounting runways to building columns or support structures, positioning the bridge, and integrating the hoist/trolley. Professional installation is recommended for safety.

Q5: What’s the difference between an overhead bridge crane and a gantry crane?

A: Overhead bridge cranes run on elevated runways (attached to a building), while Żuty grupy have ground-supported legs—making gantries better for outdoor or open spaces.
