7 吨桥式起重机

这 7 tons overhead crane is a versatile and indispensable material handling equipment widely used in industrial workshops, 仓库, 工厂, 和建筑工地. Designed to lift and transport heavy loads up to 7 tons with precision and efficiency, it plays a crucial role in optimizing production processes, reducing labor intensity, and ensuring operational safety. This product detail focuses on two main configurations: 这 7 tons single girder overhead crane and the 7 tons double girder overhead crane, highlighting their structures, 特征, advantages, and application scenarios to help you make an informed purchasing decision.

7 Tons Single Girder Overhead Crane

这 7 tons single girder overhead crane is a cost-effective and space-saving material handling solution, characterized by its simple structure, light dead weight, and easy installation. It consists of a single main beam (usually made of high-quality Q235B or Q355B steel), end carriages, hoisting mechanism, 手推车, and electrical control system. The main beam adopts a box-type welded structure, which ensures high rigidity and bending resistance while reducing the overall weight of the crane.

7 Tons Single Girder Overhead Crane Key Features

• 1. Compact Structure: With a single main beam design, the crane occupies less vertical and horizontal space in the workshop, making it ideal for facilities with limited headroom or narrow spans.
• 2. 易于安装 & 维护: The simplified structure reduces the complexity of installation, requiring fewer man-hours and lower installation costs. Routine maintenance is also convenient, with easily accessible components for inspection and replacement.
• 3. 性价比高: Compared to double girder cranes, the single girder version has a lower manufacturing cost and lower overall investment, making it a preferred choice for small and medium-sized enterprises with moderate lifting needs.
• 4. Reliable Performance: Equipped with high-quality hoisting motors, 减速器, and brakes, the crane ensures stable lifting and lowering operations. The electrical control system adopts advanced PLC control, featuring smooth operation, high control precision, and strong anti-interference ability.

7 Tons Single Girder Overhead Crane Application

Suitable for light to medium-duty material handling tasks in machinery manufacturing, auto parts processing, 仓储物流, 食品加工, and textile industries. It is especially ideal for workshops where the lifting frequency is not too high and the load is relatively stable.

7 Tons Double Girder Overhead Crane

这 7 tons double girder overhead crane is a heavy-duty and high-performance material handling equipment, designed with two parallel main beams. It offers higher stability, larger lifting height, and better load-bearing capacity compared to the single girder type. The main beams are typically box-type welded structures made of high-strength steel, ensuring excellent mechanical properties and long service life. The crane is composed of main beams, end carriages, hoisting trolley, bridge travel mechanism, electrical control system, and safety protection devices.

7 Tons Double Girder Overhead Crane Key Features

• 1. 卓越的稳定性 & Load-Bearing Capacity: The double girder structure distributes the load more evenly, providing better stability during lifting and traveling operations. It can withstand higher impact loads and is suitable for long-term heavy-duty work.
• 2. Larger Lifting Height & Working Space: The hoisting trolley runs between the two main beams, allowing for a larger lifting height compared to single girder cranes. The design also provides more flexible working space, making it easier to handle loads in complex workshop layouts.
• 3. High Working Class: Designed for high-frequency and heavy-duty operations, the working class can reach A6 – A8, meeting the needs of continuous production lines and heavy industry applications.
• 4. 全面的安全防护: Equipped with multiple safety devices, such as overload protection, 限位开关 (lifting height limit, travel limit), 紧急停止按钮, and buffer devices, ensuring the safety of operators and equipment.
