7 grúa aérea de una sola viga de una tonelada: compacto, reliable, easy maintenance for factory and warehouse lifting with spans up to 31.5m.
El 7 ton single girder overhead crane is a lightweight yet robust material-handling solution engineered for general manufacturing, warehousing and workshop applications that demand a lifting capacity beyond conventional 3–5 ton units while keeping structural weight and investment costs low.
7 grúa aérea de una sola viga de una tonelada
Built on a single box girder supported by two end carriages running on rails, the crane integrates a compact electric hoist and trolley that traverse along the girder flange. Its low headroom design means it can be installed in workshops with limited ceiling height — typically saving 300–500 mm of building height compared with double-girder configurations — which directly reduces plant construction costs. The 7-ton model fills the gap between light-duty single-girder cranes and heavier double-girder systems, making it a cost-effective choice for mid-range lifting in production lines, repair shops and storage yards.
The crane complies with international standards such as FEM and GB/T 3811, is fully customizable in span and lifting height, and can be configured with either pendant or radio remote control to suit different site layouts and operation habits.

7 grúa aérea de una sola viga de una tonelada
El 7 ton single girder overhead crane is the right choice wherever reliable, economical and space-saving lifting above 5 tons is required without the expense of a heavier double-girder system.
Q1: What is the maximum span available for a 7 grúa aérea de una sola viga de una tonelada?
A: Standard spans range from 7.5 m to 31.5 metro, and larger spans can be engineered on request depending on the rail and structural design.
Q2: Can the 7-ton single girder crane be operated by remote control?
A: Sí. It supports pendant control, control remoto por radio, and cabin operation — the control mode is selected according to the customer’s site and operating requirements.
Q3: What is the minimum workshop height needed to install this crane?
A: Thanks to its low headroom design, installation generally requires 300–500 mm less headroom than a comparable double-girder crane, which helps reduce factory building costs.
Q4: What safety devices does the crane include?
A: The crane is equipped with an overload limiter, upper and lower limit switches, an anti-drop device, anti-phase protection and an emergency stop as standard features.
Q5: Is the lifting height adjustable?
A: Sí. The lifting height is normally 6–18 m and can be customized up to 30 m based on the application.
Q6: What working duty is this crane suitable for?
A: It is rated for working duty A3–A5 (M3–M5), covering intermittent to medium-duty operation in general manufacturing and warehousing.
