А 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 ton single girder overhead crane

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.

Технические характеристики

Ключевые особенности

• ◆ Low headroom, compact design — single-girder structure minimizes required building height and maximizes usable lifting space.
• ◆ Lightweight girder, easy installation — optimized box-girder design reduces dead weight, cutting freight and installation time and cost.
• ◆ Reliable hoist system — CD1/MD1 hoist with low-speed creep option ensures precise positioning and smooth lifting of sensitive loads.
• ◆ Complete safety protection — overload limiter, верхние/нижние концевые выключатели, anti-drop device, anti-phase protection and emergency stop as standard.
• ◆ Smooth and stable travel — frequency-inverter travel option provides stepless speed control and reduces load swing.
• ◆ Durable and low-maintenance — high-strength steel, corrosion-resistant paint finish and easily replaceable standard parts lower lifecycle cost.
• ◆ Flexible control options — pendant, radio remote or cabin control to fit any operating environment.
• ◆ Customizable configurations — span, высота подъема, speed and rail profile adapted to the customer’s specific workshop layout.

А 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.

FAQ About 7 Ton Single Girder Overhead Crane

1 квартал: What is the maximum span available for a 7 ton single girder overhead crane?

А: Standard spans range from 7.5 m to 31.5 м, and larger spans can be engineered on request depending on the rail and structural design.

2 квартал: Can the 7-ton single girder crane be operated by remote control?

А: Да. It supports pendant control, radio remote control, 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?

А: 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?

А: 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?

А: Да. 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?

А: It is rated for working duty A3–A5 (M3–M5), covering intermittent to medium-duty operation in general manufacturing and warehousing.
