Шта је мостна дизалица?

Мостни кран

An overhead bridge crane is a heavy-duty material handling equipment designed to lift, преместити, 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, смањити ручни рад, and enhance safety when handling weights from a few tons to hundreds of tons. They are customizable to fit specific workspace dimensions, load requirements, и еколошки услови, making them indispensable in manufacturing, логистика, and heavy industries.

Key Features of Overhead Bridge Cranes

Мостни кран

Overhead bridge cranes are engineered for reliability, ефикасност, и сигурност. Here are their core features:

1. Висок капацитет оптерећења: Designed to handle loads ranging from 1 ton to over 500 тона, suitable for light to ultra-heavy lifting tasks.
2. Прецисе Цонтрол: Equipped with advanced hoist and trolley systems (приручник, електрични, or hydraulic) for smooth, accurate load positioning—critical for delicate operations like machinery assembly.
3. Издржљива конструкција: Built with high-strength steel girders, reinforced runways, and corrosion-resistant components to withstand harsh environments (Нпр., високе температуре, прашина, or humidity).
4. Усаглашавање на безбедности: Integrated safety features include overload protection, дугмад за хитно заустављање, крајњи прекидачи, and anti-collision systems, meeting global standards (ОСХА, ИСО, Фем).
5. Space Efficiency: 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, висина подизања, power sources (електрични, дизел), and automation (for unmanned operations).

Једноструки поклопац вс. Double Girder Overhead Bridge Cranes: Која је разлика?

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, и буџета. Here’s a breakdown:

Значајка	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.
Носивост	До 20 тона (стандардни); 50 тона (heavy-duty models).	20 tons and above (commonly 50–500+ tons).
Дужина распона	Ideal for spans up to 30 метар.	Suitable for longer spans (до 50+ метар).
Висина подизања	Moderate (limited by single girder strength).	Higher lifting heights (extra clearance due to dual girders).
Cost	More affordable (simpler design, lower material use).	Higher initial cost (sturdier build, larger components).
Најбоље за	Light to medium loads; small to medium facilities (Нпр., радионице, Складишта).	Heavy loads, large spans, or harsh environments (Нпр., челични млинови, бродоградилишта).

Technical Specifications of Overhead Bridge Cranes

Overhead Bridge Cranes

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

Тип модела	Max Lifting Capacity	Дужина распона	Висина подизања	Радничка класа (ISO/FEM)*	Напајање	Hoist Speed
Сингле Гирдер (Стандардни)	1–20 tons	5–30 m	3–12 m	A3–A5	380V/3Ph/50Hz (обичај)	0.5–10 m/min
Сингле Гирдер (Хеави-Дути)	20–50 tons	10–25 m	5–15 m	A5–A6	380V/3Ph/50Hz (обичај)	0.3–8 m/min
Двоструки носач (Стандардни)	20–100 tons	10–40 m	6–20 m	A6–A7	380V/3Ph/50Hz (обичај)	0.2–6 m/min
Двоструки носач (Ultra-Heavy)	100–500+ tons	15–50+ m	8–30 m	A7–A8	Обичај (diesel/electric)	0.1–4 m/min

Радничка класа: 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

Overhead Bridge Cranes

Overhead bridge cranes are versatile across sectors requiring heavy material handling. Кључне апликације укључују:

1. Производња: Moving raw materials (челик, aluminum) and finished products on assembly lines (аутомобилске, ваздухопловство, машинерије).
2. Складиштење & Логистика: Loading/unloading cargo, слагање палета, and organizing inventory in distribution centers.
3. металургија: Handling molten metal, инготи, and rolled steel in foundries and steel mills.
4. Изградња: Lifting building materials (челичне греде, бетонске плоче) in prefabrication yards or on-site.
5. Рударство: Transporting ore, опреме, and components in mines or processing plants.
6. Бродоградња: Assembling large ship parts and moving heavy machinery in dry docks.
7. Waste Management: Handling bulk waste or recycling materials in treatment facilities.

How to Choose the Right Overhead Bridge Crane?

Overhead Bridge Cranes

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

1. Одредите захтеве за оптерећење: 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 (висина подизања) to ensure the crane fits.
3. Assess Working Conditions: Consider environmental factors—high temperatures, прашина, 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 (Нпр., A7 for 24/7 heavy use).
5. Set a Budget: Мосне дизалице са једним носачем are more cost-effective for light tasks; double girder cranes are a long-term investment for heavy loads.
6. Prioritize Safety & Усаглашавање: Ensure the crane meets local regulations (Нпр., OSHA in the U.S., CE in the EU) and includes essential safety features.

ФАК: Мостни кран

К1: How often should an overhead bridge crane be inspected?

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

К2: Can overhead bridge cranes be automated?

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

К3: What’s the lifespan of an overhead bridge crane?

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

К4: How is an overhead bridge crane installed?

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

К5: What’s the difference between an overhead bridge crane and a gantry crane?

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