INTRODUCTION

What is this?

The flexible suspension single-girder bridge crane is a light-duty lifting device that is directly suspended from the roof truss or ceiling structure of a workshop. It features an electric hoist running along the bottom flange of a single main beam, combined with crane traveling, to achieve precise lifting and handling of workpieces, molds, goods, and more. If your workshop floor cannot accommodate rails, your building height is limited, or you need to fully utilize overhead space without occupying the floor, this product is designed for you.

Why choose flexible suspension over floor-supported cranes?

Compared to traditional floor-supported cranes, the flexible suspension solution offers four core advantages:

First, zero floor space occupation – no floor-mounted columns or rails, suspended directly from the roof, leaving the ground completely clear for forklifts and trucks to pass freely.

Second, lower installation cost – no concrete foundation required, no ground rail installation, installation time reduced by over 50%.

Third, more flexible layout – the track layout can be arranged arbitrarily according to workstation needs, supporting straight lines, curves, multi-branch, and other complex routes.

Fourth, lightweight and economical – simple structure, light self-weight, cost only 50%-60% of floor-supported cranes with the same capacity.

Free up more floor space with less investment.

What can we do for you?

We understand that every customer has different workshop structures, different workstation layouts, and different lifting height requirements. Therefore, we offer flexible customization options: lifting capacity from 0.25 ton to 5 tons; span from 3 meters to 16 meters; control options of pendant or remote radio; speed options of single speed, dual speed, or VVVF. Whether your workshop is an old low-ceiling building or a new high-standard workshop, we can match the most suitable suspension method and lifting height.

Unsure? Don't know?

Not sure whether your roof can support the suspension load? Don't know how long the track needs to be to cover all your workstations? No problem. Just tell us: your workshop structure type, the load capacity of your roof beams, and the dimensions of the working area to be covered. Our engineers will provide you with an accurate quote and installation drawings within 24 hours. Click the button below or contact us via WhatsApp/email to get your customized solution.

💡 Tip: We offer free selection consulting. Even if you are unsure about specific parameters, feel free to describe your workshop structure and handling needs, and we will calculate for you.

APPLICATION SCENARIO

[1] Assembly Workshops – Precise handling and positioning of components on production lines.

[2] Warehouses and Distribution Centers – Efficient loading, unloading, and stacking of light to medium goods.

[3] Maintenance and Repair Facilities – Lifting engines, pumps, and machinery parts for overhaul.

[4] Food and Pharmaceutical Industries – Clean and low‑dust material handling with optional stainless steel or anti‑corrosion finishes.

[5] Laboratories and Small‑scale Manufacturing – Flexible lifting where space and building strength are limited.

ADVANTAGES

[1] Lightweight and Easy Installation – Suspended design eliminates extra support columns, saving floor space.

[2] Low Headroom and Compact Structure – Maximizes lifting height even in low‑ceiling workshops.

[3] Smooth and Quiet Operation – Flexible connection reduces vibration and noise.

[4] Cost‑effective for Light Duty – Lower initial investment and energy consumption.

[5] Easy Maintenance – Modular components and accessible design reduce downtime.
