O 7 tons overhead crane is a versatile and indispensable material handling equipment widely used in industrial workshops, armazéns, fábricas, e canteiros de obras. 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: o 7 tons single girder overhead crane and the 7 tons double girder overhead crane, highlighting their structures, características, advantages, and application scenarios to help you make an informed purchasing decision.


O 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, carrinho, 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.

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

O 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.
