Подвесной кран

An underslung crane is a hoisting system suspended directly from the roof or from a steel support structure, without relying on floor columns for support. The system consists of a main girder, end beams, a hoisting mechanism, and an electrical control system, enabling the longitudinal and transverse movement of loads without occupying floor space. The VOITTO suspension underslung overhead crane system is suitable for loads ranging from 0.5 to 10 metric tons and spans from 3 to 22.5 meters. It is particularly well-suited for factory workshops, warehouses, automotive assembly lines, and maintenance facilities where floor space is limited or where existing building structures prevent the installation of floor-supported crane tracks.

Введение продукта

An underslung crane operates by suspending the main girder directly from tracks mounted on the roof or an existing steel structure, eliminating the need for support columns on the floor, as required by traditional overhead cranes. This design allows the crane to move both longitudinally and transversely, making full use of the available vertical headroom without occupying floor space in the facility.

When faced with limited floor space, building structures unsuitable for installing floor-supported tracks, or the need to upgrade existing facilities without major structural modifications, buyers typically opt for underhung overhead cranes. However, compared to floor-supported systems, overhead cranes have a lower maximum load capacity and a shorter span. Therefore, users must confirm the building structure’s load-bearing capacity, the required load, and the span requirements before selecting a model.

Typically, users employ single-girder underhung overhead cranes in the machinery manufacturing, automotive, and food processing industries to perform material handling tasks.

Преимущества

The advantages of suspended cranes stem directly from their installation method: Since the main girder is suspended from the building’s existing roof or steel structure rather than supported by columns on the ground, these cranes offer high space utilization, ease of operation, and low installation and maintenance costs. The following is a summary of the features and advantages of suspended underhung overhead cranes.

• Space-saving: The equipment is installed directly on the existing beam structure of a factory or warehouse, eliminating the need for additional columns or support structures.
• Высокая гибкость: The equipment is suitable for a variety of operating environments and can meet the needs of general light industrial and warehousing applications.
• Простое управление: The equipment supports operation via a ground-level control handle or wireless remote control.
• Простая установка: The equipment has a relatively simple structure, making installation and commissioning convenient and requiring minimal routine maintenance.

Технические характеристики подвесного крана

When selecting an underslung crane, the key parameters to confirm are lifting capacity, span, and lifting height — these determine whether the crane fits your existing roof structure and load requirements. Work duty class reflects how frequently and intensively the crane will operate, while hoist type and control mode affect day-to-day handling. Because an underslung crane relies on the building’s roof or steel structure for support, building structural capacity should always be verified alongside these specifications.

Приложение

Underslung overhead cranes do not take up floor space, making them ideal for work environments where floor space is limited but material handling at height is still required.

• Factory Workshops: Users control the equipment to perform material handling tasks on production lines.
• Складирование и логистика: Operators use the equipment to handle, load, unload, and stack heavy cargo within warehouses.
• Автомобилестроение: Users control the equipment to transport vehicle bodies, engines, and large components along assembly lines.
• Maintenance Workshops: Operators use the equipment to handle large components during aircraft and train maintenance.

Underslung Crane vs Overhead Crane

Underslung Overhead Crane Cost Factors

The price of an underslung overhead crane depends on a variety of factors: lifting capacity, span, and lifting height are the primary cost determinants, followed by hoist type, duty class, and electrical control components. Below, I will list the price ranges for suspended overhead cranes with different configurations for reference only; actual prices are subject to specific specifications.

Часто задаваемые вопросы

Разница между подвесным краном и краном Eot?

Главный балка подвесного крана подвешена под крышной рельсовой дорогой, что позволяет сэкономить площадь пола, но требует высокой несущей способности крыши. В отличие от этого, мост подвесного крана устанавливается над верхней рельсовой дорогой. Основное различие между ними заключается в способах опоры и установки моста.

Разница между подвесным краном и взрывозащищенным мостовым краном?

Разница между подвесными кранами и взрывозащищенными мостовыми кранами заключается в их применении и конструкции. Подвесные краны имеют главные балки, подвешенные под рельсами на крыше, что позволяет сэкономить место и снизить затраты. Взрывозащищенные мостовые краны, с другой стороны, состоят из взрывозащищенных двигателей, электрических компонентов и защитных конструкций, что делает их пригодными для использования во взрывоопасных средах.

Разница между подвесным краном и европейским мостовым краном?

Разница между подвесным краном и европейским мостовым краном заключается в их конструкции. Подвесные краны используют для опоры подвесные рельсы, установленные на крыше, а главная балка проходит под рельсами. В отличие от подвесного крана, европейский мостовой кран имеет меньший вес и меньшие габаритные размеры при той же грузоподъемности.

Does an Underslung Crane Require Floor Columns?

No — it is suspended from the roof or existing steel structure, which is the main reason it saves floor space compared with a conventional overhead crane.

Can an underslung crane be installed in an existing factory?

Yes, provided the existing roof or steel structure can support the additional suspended load — this should be confirmed with an engineering review first.
