Grua suspensa

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.

Introdução ao produto

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.

Vantagens

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.
• Elevada flexibilidade: The equipment is suitable for a variety of operating environments and can meet the needs of general light industrial and warehousing applications.
• Operação fácil: The equipment supports operation via a ground-level control handle or wireless remote control.
• Instalação fácil: The equipment has a relatively simple structure, making installation and commissioning convenient and requiring minimal routine maintenance.

Especificações do guindaste suspenso

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.

Aplicação

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.
• Armazenagem e Logística: Operators use the equipment to handle, load, unload, and stack heavy cargo within warehouses.
• Fabricação Automotiva: 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.

Perguntas frequentes

Diferença entre guindaste suspenso e guindaste EOT?

A viga principal de uma grua suspensa é suspensa abaixo do trilho do telhado, economizando espaço no piso, mas exigindo alta capacidade de carga do telhado. Em contrapartida, a ponte de uma grua suspensa é instalada acima do trilho superior. A principal diferença entre as duas reside nos métodos de suporte e instalação da ponte.

Diferença entre guindaste suspenso e guindaste suspenso à prova de explosão?

A diferença entre guindastes suspensos e guindastes aéreos à prova de explosão reside na sua aplicação e conceção estrutural. Os guindastes suspensos têm vigas principais suspensas abaixo dos trilhos do telhado, economizando espaço e reduzindo custos. Os guindastes aéreos à prova de explosão, por outro lado, são compostos por motores à prova de explosão, componentes elétricos e estruturas de proteção, tornando-os adequados para uso em ambientes inflamáveis e explosivos.

Diferença entre guindaste suspenso e ponte rolante europeia?

A diferença entre uma grua suspensa e as gruas suspensas europeias reside no seu design estrutural. As gruas suspensas utilizam calhas de suspensão montadas no teto como suporte, com a viga principal a passar por baixo das calhas. Ao contrário da grua suspensa, a grua suspensa europeia tem um peso mais leve e dimensões estruturais mais pequenas com a mesma capacidade de elevação.

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.
