palan électrique pour portique monopoutre

A WEIHUA single girder gantry crane features a single main beam supported by two rigid legs, creating a gateway-like structure that operates independently of building frames—making it ideal for both indoor and outdoor use. Equipped with high-quality electric hoists (either wire rope or chain types), these cranes are engineered for light to medium-duty lifting, offering a perfect balance of performance, durabilité, and affordability compared to double girder alternatives. Whether you need standard configurations or customized solutions, WEIHUA’s single girder gantry cranes are built to enhance productivity, assurer la sécurité, and support long-term business growth.

Core WEIHUA Single Girder Gantry Crane Specifications

Understanding the key specifications is critical to choosing the right crane for your needs. Below are the standard and customizable specs that define WEIHUA’s single girder gantry crane lineup, based on industry standards and real-world application requirements:

1. Capacité de chargement

Single girder gantry cranes are available in a wide range of load capacities to suit different operational demands. The standard range typically spans from 1 tonner à 32 tonnes, with customization options for special projects requiring higher capacities. Par exemple, models equipped with WEIHUA’s CD & MD wire rope hoists can handle up to 32 tonnes, while those with NR wire rope hoists are ideal for loads up to 12.5 tonnes. This versatility makes them suitable for everything from light warehouse tasks to medium-duty industrial lifting.

2. Longueur de portée

The span length (distance between the two legs of the crane) directly impacts the crane’s coverage area. WEIHUA’s single girder gantry cranes offer standard span lengths from 8 mètres à 35 mètres, with flexible adjustments to fit your workspace. L-type leg models, par exemple, feature a span range of 18m to 35m and excel in outdoor settings where space utilization is key. The span can also be customized to accommodate narrow workshops, large construction yards, or unique site layouts—ensuring the crane covers every inch of your operational area efficiently.

3. Hauteur de levage

Hauteur de levage (the maximum distance the hook can rise from the ground) is another critical specification, especially for warehouses with high ceilings or outdoor sites requiring vertical lifting. WEIHUA’s standard single girder gantry cranes offer lifting heights from6 meters to 30 mètres, with customization options for taller applications. Par exemple, models used in ports or construction sites may require extended lifting heights to handle large equipment or containers, while warehouse models can be tailored to fit lower ceiling heights for space efficiency.

4. Classe ouvrière

Classe ouvrière (or duty cycle) refers to the crane’s ability to handle repeated lifting operations over time, as defined by FEM/ISO standards. WEIHUA single girder gantry cranes typically fall into Class A3 to A5, making them ideal for light to medium-duty applications. Class A3 models are suitable for occasional use (Par exemple, petits ateliers), while Class A5 models are designed for more frequent, fonctionnement continu (Par exemple, busy logistics hubs or manufacturing plants). This ensures the crane can withstand the demands of your daily operations without compromising performance or safety.

5. Type de palan & Vitesse

WEIHUA single girder gantry cranes are equipped with two main types of electric hoists, each tailored to specific needs:

• ◆ CD & MD Wire Rope Hoists: These are the most common options, offering single or dual-speed control. CD hoists provide single-speed operation (3~8 m/min), while MD hoists offer two-speed options (0.33~8 m/min) for precise lifting. They are easy to install, maintenir, et rentable, making them ideal for most industrial applications.
• ◆ NR Wire Rope Hoists: Featuring a C-shaped layout for better space utilization, these hoists are maintenance-free for 3~5 years and operate with inverter control (0.5~5 m/min lifting speed). They are perfect for applications where space is limited and low noise is a priority.

En plus, the trolley and crane traveling speeds are typically 20 m / mon (single speed) or 2~20 m/min (inverter control), ensuring smooth and efficient movement across the workspace.

6. Contrôle & Alimentation électrique

Single girder gantry cranes offer flexible control options to suit different operator preferences and safety needs: télécommande sans fil (for operation from a safe distance) and ground handle control (push button) (for close-range operation). The power supply is standard 3-phase AC (380V/50 Hz), with customization available for regional standards (Par exemple, 220V/60Hz for North American markets). This adaptability ensures the crane integrates seamlessly with your existing power infrastructure.

7. Environnement opérationnel

These cranes are designed to withstand harsh industrial conditions, with a standard operating temperature range of -20°C to +40°C. They are suitable for both indoor and outdoor use, with optional weatherproofing features (Par exemple, revêtements résistants à la corrosion) for outdoor or coastal applications. The electrical system has a protection class of IP55 (or higher upon request), ensuring durability against dust, humidité, and other environmental factors.

Key Features Beyond the Specifications

While specifications define performance, WEIHUA’s single girder gantry cranes offer additional features that set them apart:

• ◆ Compact & Conception peu encombrante: The single main beam (généralement fabriqué en acier Q235B ou Q345B à haute résistance) and lightweight frame optimize space utilization, making them ideal for narrow workspaces. L-type and C-type leg designs further enhance space efficiency, allowing cargo to pass through legs smoothly.
• ◆ Systèmes de sécurité avancés: Multiple safety protections include overload protection, limit switches for lifting height and travel distance, boutons d'arrêt d'urgence, and anti-derail devices—all meeting ISO and CE standards to minimize accident risks.
• ◆ Faible entretien & Durabilité: Composants de haute qualité (Par exemple, Schneider electrical parts, sealed bearings) and corrosion-resistant coatings reduce wear and tear, lowering maintenance costs. Models with NR hoists are maintenance-free for 3~5 years, minimiser les temps d'arrêt.
• ◆ Customization Options: WEIHUA offers tailored solutions, including weatherproof designs, special hooks or slings for irregular loads, rubber-tired travel systems, and integration with automation systems for smart factories.

Applications of Single Girder Gantry Cranes

Thanks to their versatile specifications and features, single girder gantry cranes are used across a wide range of industries:

• ◆ Fabrication: Levage de matières premières, produits semi-finis, and finished goods in automotive, machinerie, and electronics workshops.
• ◆ Warehousing & Logistique: Loading/unloading trucks, empiler des palettes, et organiser l'inventaire dans les entrepôts et les centres de distribution.
• ◆Construction: Hoisting steel, béton, and equipment at building sites, ponts, et projets d'infrastructures.
• ◆ Ports & Terminaux: Manutention de conteneurs, cargaison en vrac, et marchandises générales dans les ports et terminaux intérieurs de petite et moyenne taille.
• ◆ Exploitation minière & Métallurgie: Transporter des minerais, ferraille, et matériaux transformés dans les mines et fonderies.
