3. What is an Overhead Crane in a Factory ?

In the manufacturing environment of factories, an overhead crane plays a crucial role in the transportation and lifting of materials and products. Understanding the different types of overhead cranes and their installation procedures is essential to ensure efficiency and safety in the production process. In fact, there are several common types of overhead cranes used in factories.

An overhead crane in a factory is a heavy-duty crane system that consists of a bridge crane running on an overhead runway, combined with one or more hoists to lift and move materials or goods during the production process. The structure of an overhead crane in a factory includes the main beam, end beams, lifting mechanism, and control system.

4. Types of Overhead Cranes in Factories

In factories, various types of overhead cranes are used to meet different lifting and transportation requirements. Here are some popular types of overhead cranes:

4.1. Single Girder Overhead Crane

Furthermore, the single girder overhead crane offers excellent versatility and efficiency in handling various materials and goods. It is widely utilized in industries such as manufacturing, warehousing, and logistics due to its compact design and ease of operation. Additionally, this type of crane can be equipped with advanced safety features and remote control systems, ensuring enhanced productivity and worker safety.

Structure: Consists of one main girder and a hoist assembly below.
Lifting capacity: 0.5-5 tons.
Advantages: Simple design, low cost, suitable for small factories.
Examples: 3-ton overhead crane, 5-ton overhead crane.

4.2. Double Girder Overhead Crane

The double girder overhead crane is an upgraded version of the single girder overhead crane. It consists of two parallel running bridge cranes on the runway and two independent hoist assemblies. Double girder overhead cranes have the ability to lift and move loads more quickly and efficiently compared to single girder cranes. They are more commonly used in businesses and factories with higher lifting capacities. Double girder overhead cranes can be adjusted for speed and provide stable operation to meet the production needs of businesses.

Structure: Consists of two main girders, two end beams, control system, lifting mechanism.
Lifting capacity: 3-15 tons. Suitable for heavier lifting tasks than single girder cranes.
Examples: 5-ton overhead crane, 10-ton overhead crane.

**There are multiple types of overhead cranes used in warehouses to meet transportation requirements.**

4.3. A-Frame Overhead Crane

The A-frame overhead crane, unlike other overhead cranes, is a type of crane designed in the shape of an “A.” It is characterized by a bridge crane running on an A-shaped overhead runway and a hoist assembly positioned in the middle. Therefore, A-frame overhead cranes are ideally suited for factories with limited space and require flexible movement.

A-shaped structure, capable of 360-degree rotation.
Lifting capacity: 5-30 tons. Suitable for narrow spaces and heavy transportation within warehouses.
Suitable for industrial production and heavy machinery transportation.

4.4. Monorail Overhead Crane

The monorail overhead crane, operating on a single rail, stands out as a space-efficient lifting solution. This crane configuration comprises a bridge crane traversing along a horizontal rail, complemented by a hoist assembly dedicated to the seamless lifting and movement of goods. Specifically designed for confined spaces and short travel distances, monorail overhead cranes provide optimal performance in scenarios where space is at a premium, making them a versatile choice for efficient material handling in industrial environments.

Rail mounted high on the ceiling or wall, with only one beam moving along the rail.
Lifting capacity: 5-50 tons. Suitable for large spaces and heavy transportation across different areas.

4.5. Rotating Overhead Crane

The rotating overhead crane, renowned for its capacity to pivot around an axis, represents an innovative solution for seamless material handling. This crane configuration incorporates a bridge crane seamlessly traversing along a dedicated runway, accompanied by a highly adaptable hoist assembly capable of independent rotation around its axis. Specifically designed to excel in lifting and transporting goods within expansive spaces, rotating overhead cranes are essential for operations demanding not only strength but also unparalleled flexibility in movement. This makes them a preferred choice for efficiently managing material handling challenges in large industrial settings.

Capable of 360-degree rotation around the crane post to access all directions.
Lifting capacity: 10-100 tons. Suitable for tasks that require multi-point access.

5. Installation of Overhead Cranes for Warehouse Safety

Ensuring the safe and effective installation of workshop overhead cranes involves following specific steps:

5.1. Basic Preparation

Before starting the installation, accurately determine the positioning of the overhead crane within the warehouse. Ensure that the warehouse floor is sufficiently sturdy to support the crane’s load. If necessary, reinforce the floor.

5.2. Installation of End Beams

To start the installation process, first, carefully position the two end beams on both ends of the main beam. These end beams are vital as they not only provide cushioning but also serve as the crane’s final stopping point. For a secure and safe installation, utilize bolts, screws, and connecting accessories.

5.3. Installation of Remaining Components

Install other components such as auxiliary beams, crossbars, and guardrails. These components provide support and protection for the overhead crane. Use bolts, screws, and connecting accessories to ensure their tight installation onto the main beam.
