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. ظرفیت بار

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 تن به 32 تن, with customization options for special projects requiring higher capacities. به عنوان مثال, models equipped with WEIHUA’s CD & MD wire rope hoists can handle up to 32 تن, while those with NR wire rope hoists are ideal for loads up to 12.5 تن. This versatility makes them suitable for everything from light warehouse tasks to medium-duty industrial lifting.

2. طول دهانه

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 متر به 35 متر, with flexible adjustments to fit your workspace. L-type leg models, به عنوان مثال, 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. ارتفاع بلند کردن

ارتفاع بلند کردن (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 متر, with customization options for taller applications. به عنوان مثال, 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. طبقه کارگر

طبقه کارگر (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 (به عنوان مثال, کارگاه های کوچک), while Class A5 models are designed for more frequent, عملیات مداوم (به عنوان مثال, busy logistics hubs or manufacturing plants). This ensures the crane can withstand the demands of your daily operations without compromising performance or safety.

5. نوع بالابر & سرعت

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, حفظ کند, و مقرون به صرفه, 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.

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

6. کنترل کنید & منبع تغذیه

Single girder gantry cranes offer flexible control options to suit different operator preferences and safety needs: کنترل از راه دور بی سیم (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/50Hz), with customization available for regional standards (به عنوان مثال, 220V/60Hz for North American markets). This adaptability ensures the crane integrates seamlessly with your existing power infrastructure.

7. محیط عملیاتی

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 (به عنوان مثال, پوشش های مقاوم در برابر خوردگی) for outdoor or coastal applications. The electrical system has a protection class of IP55 (or higher upon request), ensuring durability against dust, رطوبت, 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 & طراحی صرفه جویی در فضا: The single main beam (معمولاً از فولاد با مقاومت بالا Q235B یا Q345B ساخته شده است) 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.
• ◆ سیستم های ایمنی پیشرفته: Multiple safety protections include overload protection, limit switches for lifting height and travel distance, دکمه های توقف اضطراری, and anti-derail devices—all meeting ISO and CE standards to minimize accident risks.
• ◆ تعمیر و نگهداری کم & دوام: قطعات با کیفیت بالا (به عنوان مثال, 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, به حداقل رساندن زمان توقف.
• ◆ 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:

• ◆ تولید: بالا بردن مواد اولیه, محصولات نیمه تمام, and finished goods in automotive, ماشین آلات, and electronics workshops.
• ◆ Warehousing & لجستیک: Loading/unloading trucks, انباشتن پالت ها, و ساماندهی موجودی در انبارها و مراکز توزیع.
• ◆ ساخت و ساز: Hoisting steel, بتن, and equipment at building sites, پل ها, و پروژه های زیربنایی.
• ◆ پورت ها & پایانه ها: جابجایی ظروف, محموله فله, و کالاهای عمومی در بنادر کوچک تا متوسط ​​و پایانه های داخلی.
• ◆ معدن & متالورژی: حمل و نقل سنگ معدن, آهن قراضه, و مواد فرآوری شده در معادن و کارخانه های ذوب.
