A freestanding bridge crane is a self-supporting lifting device. The entire equipment does not rely on the roof beams or columns of the factory for load-bearing. It requires only a simple foundation (C30 concrete, thickness >200 mm), effectively reducing construction cost for a factory or Repair workshop.
A freestanding bridge crane is a self-supporting lifting system with a modular design, requiring only a simple C30 concrete foundation without roof reinforcement. Lifting capacity ranges from 0.25 to 5 tons with spans of 1–12.5 meters. Applied across industrial manufacturing, automotive production, and repair workshops. Next, this page will provide a detailed introduction to this self-supporting lifting device.
A freestanding bridge crane is a self-supporting overhead lifting system that operates independently of a building’s roof beams or columns. Its self-supporting design allows for easy installation and dismantling, enabling the equipment to be deployed across different work areas and serving as a cost-effective solution to meet ever-changing production demands. Therefore, freestanding overhead cranes are an ideal choice for facilities with limited structural load-bearing capacity.
Unlike traditional overhead cranes, this workstation overhead crane features a modular frame structure, with the self-supporting frame mounted on a concrete foundation at ground level. It requires only a simple foundation (C30 concrete, thickness >200 mm), effectively reducing construction cost for a factory or Repair workshop. This design offers factories and workshops the advantages of quick installation, reduced construction costs, and a high degree of flexibility.
The freestanding workstation bridge crane is an ideal material handling solution that is efficient, economical, and easy to install. VOITTO crane offers customized designs based on users’ specific needs and material handling routes.
Freestanding bridge cranes can be classified into different types based on their structure and materials, including flexible freestanding bridge cranes, rigid freestanding overhead cranes, single-girder structures, double-girder structures, and aluminum alloy freestanding bridge crane types. These types are described below.
Pont roulant monopoutre autoportant
Double Girder Workstation Bridge Crane

Pont roulant monopoutre autoportant: This type features a single main girder. The hoisting mechanism runs along the lower flange of the main girder and is used for the vertical lifting and horizontal handling of materials. Its rated lifting capacity typically does not exceed 2 tons.
Double Girder Workstation Crane: Compared to single-girder structures, double-girder freestanding workstation cranes offer greater load-bearing capacity and smoother operation, making them suitable for handling medium- to large-sized materials. Their lifting capacity ranges from 125 kilograms to 3.2 tons.
Rigid Monorail Crane System: This equipment utilizes a rigid steel frame structure as its support system. These cranes exhibit minimal deformation during operation, offering high stability and strong resistance to sway. Their rated lifting capacity typically ranges from 125 kilograms to 2 metric tons, with some reinforced structures capable of handling 3 tons.
Flexible Workstation Crane: This type is constructed from lightweight, modular steel components. The main girder and rails are bolted together to form a frame structure, making installation and disassembly extremely convenient. These cranes are suitable for work environments where the load capacity does not exceed 2 metric tons.
Aluminum Alloy Freestanding Workstation Bridge Crane: This type uses aluminum alloy as its primary structural material. The entire unit is characterized by light weight, high strength, corrosion resistance, and rust-free properties. It is widely used in environments with high requirements for cleanliness and flexibility, such as food processing, pharmaceuticals, electronics, aerospace, assembly lines, and laboratories.

Monorail cranes are suspended lifting devices that operate along a single fixed rail. Using electric hoists, they can transport materials along straight or curved paths to designated points. They are used in indoor industrial environments such as workshops, production lines, and warehouses, and are suitable for material handling scenarios where there are defined logistics routes between workstations. This article systematically introduces the structural characteristics, common types, primary components, and operating principles of these systems. It analyzes their differences from bridge cranes and jib cranes through typical industrial applications. Additionally, it outlines selection criteria for monorail cranes based on key factors such as lifting capacity, track layout, and operating conditions. What Is a Monorail Crane? the cranes are overhead lifting devices installed within factory buildings, transporting materials from one workstation to another along a fixed rail. These systems operate along predetermined routes and are primarily used in production and assembly scenarios where workpieces require movement according to fixed processes. They feature a simple structure and offer flexible operation. Types of monorail crane Monorail cranes can be classified based on their track…
The right overhead crane in the automobile industry is defined by production stage, not by tonnage alone. A stamping press needs a 20–32 t die-gripper crane with ±1 mm positioning accuracy. A trim-and-final assembly cell needs a 250–500 kg KBK aluminum rail system that operators can push by hand. Specifying one without the other wastes budget or creates a safety gap. Automotive plants run 24 hours a day at duty class M5–M6 (per FEM 1.001), and unplanned crane downtime translates directly to line stoppage. Engineers and procurement managers need cranes matched to load, cycle frequency, and environmental conditions — not a generic “overhead crane for auto” catalog page. This guide maps every major production stage to the correct crane type, key specifications, and compliance requirements. Use the table in the next section to shortcut your selection process. TL;DR: Cranes in Automotive Production • Production Scope: Overhead cranes in the automobile industry support six distinct production stages, each requiring specific crane types and lifting capacities. • System Selection: Use double-girder bridge cranes (5–50 t) for stamping and body-in-white; utilize KBK rail…
