Main Girder: The core load-bearing structure of the crane, spanning between the workshop rails, supporting the entire lifting system.

Hoisting Mechanism: Responsible for lifting and lowering loads. It consists of components such as the electric motor, reducer, drum, wire rope, and hook.

Trolley System: Installed on the main girder, moving left and right along it.

Traveling Mechanism: Used to control the entire crane's forward and backward movement along the workshop rails.

Control System: Used to operate various crane functions. Control methods include pushbutton control, remote control, or automated control systems, improving operational convenience and precision.

Electrical System: Provides power to the crane and controls the operation of various electrical components.

Main Types of Factory Cranes

Minecranes factory cranes are available in several configurations to accommodate different workshop layouts, lifting capacities, and production requirements. Selecting the right crane type depends on factors such as available space, load weight, lifting frequency, and workflow efficiency. In manufacturing plants, several crane systems are commonly used to support material handling, equipment installation, and assembly operations.

Below are the main types of factory cranes widely used in industrial facilities.

Overhead Crane

An Overhead Crane, also known as a bridge crane, is one of the most widely used lifting systems in manufacturing plants. It runs on rails installed on building structures and moves loads across the workshop using a bridge beam and hoist mechanism. This design allows the crane to cover a large working area and efficiently transport heavy components within the factory.

Applications: Production line material handling, heavy equipment installation, large component assembly in manufacturing plants.

Lifting capacity: 1 – 50 tons

Span: 7.5 – 30 m

Lifting height: 6 – 30 m

Travel speed: 20 – 120 m/min

Gantry Crane

A Gantry Crane is a freestanding crane supported by two legs that move on ground-mounted rails or wheels. Unlike overhead cranes, it does not rely on the factory building structure, making it suitable for workshops, warehouses, and outdoor factory yards where flexible lifting solutions are required.

Applications: Handling heavy machinery and equipment, material transport in fabrication workshops, outdoor yard handling and loading operations.

Lifting capacity: 2 – 100 tons

Span: 10 – 35 m

Lifting height: 6 – 18 m

Traveling speed: 20 – 60 m/min

Jib Crane

A Jib Crane is a compact lifting device designed for localized material handling at individual workstations. It features a horizontal arm mounted on a column or wall that can rotate within a specific angle, allowing operators to easily lift and position loads within a limited working radius.

Applications: Machine loading and unloading, workpiece positioning in assembly stations, handling small to medium components in production lines

Lifting capacity: 0.25 – 5 tons

Arm length: 2 – 10 m

Rotation angle: 180° – 360°

Lifting height: 3 – 12 m

Magnetic Crane

A Magnetic Crane is designed for handling ferromagnetic materials such as steel plates, billets, and scrap metal. It is equipped with an electromagnetic lifting device that allows steel materials to be lifted quickly without hooks or slings, improving efficiency in steel handling operations.

Applications: Steel plate and billet handling, scrap metal transportation, steel warehouses and metal processing plants.

Lifting capacity: 1 – 20 tons

Magnetic lifting force: customized based on load weight

Power supply: electromagnetic lifting system

Control mode: remote control or cabin operation

Grab Crane

A Grab Crane is equipped with a mechanical or hydraulic grab bucket for handling bulk materials such as sand, coal, grain, or aggregates. It is widely used in industries that require efficient loading, unloading, and transportation of loose materials.

Applications: Bulk material handling in factories, sand, coal, and aggregate transport, raw material storage yard operations

Lifting capacity: 5 – 25 tons

Grab bucket capacity: 0.5 – 10 m³

Span: 10 – 30 m

Lifting height: 8 – 25 m

Common Applications of Factory Cranes

Factory cranes are widely used across many manufacturing and industrial sectors to improve efficiency, safety, and workflow in material handling operations. By enabling the lifting, positioning, and transportation of heavy components, these cranes play an essential role in supporting production lines, equipment installation, and internal logistics. From precision assembly to heavy-duty material movement, factory cranes help manufacturers handle large loads quickly and safely while reducing manual labor.

Metal Fabrication

In metal fabrication workshops, factory cranes are used to lift and transport steel plates, metal sheets, and fabricated components between cutting, bending, welding, and finishing stations. Cranes help ensure safe handling of heavy metal parts and improve workflow efficiency in fabrication lines. Common equipment used includes Overhead Crane, Jib Crane, and Magnetic Crane for steel plate handling.

Automotive Manufacturing

Automotive factories rely heavily on cranes for moving vehicle frames, engine components, molds, and assembly fixtures throughout the production process. Factory cranes support tasks such as equipment installation, production line material supply, and heavy component positioning during vehicle assembly. Typical lifting solutions include Overhead Crane for assembly lines and Jib Crane for workstation-level operations.

Steel Processing

Steel plants and processing workshops use cranes to handle steel billets, plates, coils, and scrap materials. Due to the heavy weight and magnetic properties of steel products, specialized cranes equipped with electromagnetic lifting devices are commonly used. Systems such as Magnetic Crane and heavy-duty Overhead Crane enable efficient material movement within steel warehouses and processing lines.

Heavy Machinery Production

Manufacturers of construction equipment, industrial machinery, and large mechanical components require cranes to lift and assemble oversized parts. Factory cranes are used to transport castings, large frames, and mechanical assemblies across production areas. High-capacity systems such as Overhead Crane and Gantry Crane are typically used to support heavy machinery manufacturing processes.

Warehouse and Logistics Handling

In warehouses and industrial logistics centers, cranes help move heavy goods, equipment, and bulk materials between storage areas and loading zones. They are commonly used for loading large components, organizing storage yards, and improving material flow within logistics operations. Systems such as Gantry Crane and Grab Crane are often used for efficient cargo handling and bulk material movement.

Differences Between Factory Cranes and General Cranes

Although both are used for lifting and handling heavy objects, there are significant differences in usage environment, structural design, work intensity, and application scenarios. Let's understand them through a table.

Factory cranes are more suitable for stable industrial production environments and high-frequency material handling, while general cranes emphasize mobility and temporary lifting capabilities. When selecting lifting equipment, enterprises should choose the appropriate crane type based on the actual working environment, load weight, and usage frequency.

How to Choose the Right Factory Crane

Selecting the right factory crane is critical to ensuring safe, efficient, and cost-effective material handling within a facility. Choosing the wrong lifting system can lead to production delays, safety hazards, and increased operating costs. Key factors to consider include: lifting capacity, lifting height, span and coverage of the work area, suitability of the crane type, shop layout, and frequency of use.

By carefully evaluating these aspects, you can match a crane system to your specific operational needs, whether moving heavy machinery, handling steel, or processing bulk cargo. Below is a selection guide table:
