What Are the Types of Indoor Cranes?

The three main types of cranes used for indoor use are overhead cranes, portable gantry cranes, and indoor jib cranes, which come in different types.

During production in the workshop or transportation in the warehouse, it may be necessary to handle heavy materials, and manual handling is often inefficient and can pose safety hazards. Therefore, indoor cranes have become a popular tool in workshops and warehouses in different industries. Indoor cranes can provide efficient and safe solutions for indoor material handling and lifting tasks. This article explores the different types of indoor cranes, their uses, and the unique features they offer.

1. Overhead Cranes

Overhead Cranes are versatile lifting systems used in various industrial settings. They are designed to lift and transport heavy loads efficiently across large areas. Yuantai offers a wide range of overhead crane types, each tailored for specific applications and operational needs. Below are the types of overhead cranes provided by Yuantai:

1.1 Single Girder Overhead Crane

• Description: A cost-effective solution featuring a single girder with the hoist running on the lower flange.
• Applications: Suitable for light to medium-duty tasks, such as maintenance, manufacturing, and assembly lines.
• Advantages:
  • Simple structure and easy installation.
  • Reduced weight and material cost compared to double girder cranes.

1.2 Double Girder Overhead Crane

• Description: Equipped with two girders, providing higher load capacities and lifting heights.
• Applications: Used for heavy-duty operations, such as in steel mills, power plants, and shipyards.
• Advantages:
  • Supports a broader range of lifting equipment.
  • Allows for greater hook approach and lifting speed.

1.3 Ceiling-Mounted Suspension Overhead Crane

• Description: Designed for facilities with limited floor space, this crane is mounted directly onto the ceiling structure.
• Applications: Ideal for workshops or production lines where ground space needs to remain unobstructed.
• Advantages:
  • Efficient use of vertical space.
  • No need for supporting columns, optimizing workspace layout.

1.4 Explosion-Proof Overhead Crane

• Description: Engineered for hazardous environments where flammable gases, vapors, or dust are present.
• Applications: Commonly used in petrochemical plants, refineries, and chemical processing facilities.
• Advantages:
  • Complies with stringent safety standards.
  • Features specialized materials and components to prevent sparks or ignition.

1.5 Grab Bucket Overhead Crane

• Description: Equipped with a grab bucket attachment for handling bulk materials like coal, sand, or scrap metal.
• Applications: Widely used in waste recycling, mining, and material storage industries.
• Advantages:
  • Efficient for material handling with minimal manual intervention.
  • Customizable grab buckets for specific materials.

1.6 Ladle Overhead Crane

• Description: Designed specifically for metallurgical operations, this crane handles molten metal safely.
• Applications: Found in steel plants and smelting facilities.
• Advantages:
  • High-temperature resistance.
  • Equipped with advanced safety mechanisms for reliable operation.

1.7 Freestanding Workstation Overhead Crane

• Description: A modular crane system that operates independently from building structures.
• Applications: Perfect for workstations, assembly lines, and small-scale manufacturing.
• Advantages:
  • Easy to relocate and reconfigure.
  • Ideal for facilities without the infrastructure to support traditional overhead cranes.

2. Indoor Jib Cranes

Overview

Jib Cranes are compact and flexible, designed to support localized lifting tasks. These cranes consist of a vertical mast and a horizontal jib arm, enabling the hoist to cover a circular or semi-circular area.

Types of Indoor Jib Cranes

Pillar Jib Crane

• Mounted on the floor with a vertical column and capable of 360-degree rotation.
• Ideal for tasks such as machine loading and small-scale assembly.

Wall-Mounted Jib Crane

• Fixed to a wall or column and provides 180-270 degrees of rotation.
• Perfect for areas with limited floor space.

Wall-Traveling Jib Crane

• Operates along a track fixed to a wall, offering horizontal movement in addition to rotation.
• Used in facilities requiring extended coverage along walls.

Benefits of Indoor Jib Cranes

• Space-efficient design.
• Easy installation and low maintenance.
• Customizable to specific lifting needs.

3. Portable Gantry Cranes

Overview

Portable Gantry Cranes are lightweight and mobile, making them ideal for temporary lifting tasks in indoor settings. They feature an adjustable frame, enabling height modifications to suit varying requirements.

Types of Portable Gantry Cranes

Adjustable Height Portable Gantry Crane

• Equipped with adjustable legs for height variation.
• Used in maintenance, assembly, and warehouse applications where flexibility is crucial.

• Mobility: Wheels or casters allow easy movement across different workstations.
• Customization: Adjustable height accommodates diverse lifting scenarios.
• Durability: Built with sturdy materials to handle heavy loads.

Aluminum Mobile Gantry Cranes

• Material handling in warehouses.
• Maintenance of machinery and equipment.
• Temporary lifting tasks during construction or assembly.

• Adjustable height enhances versatility.
• Easy mobility ensures operational flexibility.
• Strong yet lightweight construction for durability.

Factors to Consider When Choosing an Indoor Crane

1. Lifting Capacity

The required lifting capacity determines the crane type. Overhead bridge cranes are suitable for heavy-duty applications, while jib cranes and small indoor cranes handle lighter loads.

2. Space Constraints

Evaluate the available space. Indoor jib cranes are excellent for localized lifting in compact areas, while portable gantry cranes offer mobility in wider spaces.

3. Mobility

For tasks requiring frequent repositioning, consider portable gantry cranes or adjustable mobile gantry cranes.

4. Height Requirements

Adjustable height gantry cranes are ideal for facilities with varying lifting height needs.

5. Safety Features

Ensure the crane includes essential safety features, such as overload protection, limit switches, and emergency stop mechanisms.

Conclusion

Indoor cranes are tools that assist in the handling and lifting of materials indoors, and different cranes can be selected based on various indoor conditions. Yuantai offers overhead bridge cranes, portable gantry cranes, and jib cranes for indoor use, all of which can be customized to provide you with a tailored indoor lifting solution.
