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:

2. Indoor Jib Cranes
Jib Cranes are versatile lifting solutions designed for efficient material handling in various industrial settings. Yuantai offers five primary types of indoor jib cranes, each tailored to specific operational needs and spatial constraints. Below is an overview of these crane types:
2. Floor Mounted Jib Crane
Also known as pillar-mounted jib cranes, these are free-standing units anchored to the floor, offering 360° rotation. They are suitable for short-range or intensive lifting tasks in workshops, warehouses, and docks. With lifting capacities ranging from 0.5 to 10 tons and spans up to 10 meters, they provide high efficiency and flexibility in three-dimensional space.
5. Mobile Jib Crane
Mobile or portable jib cranes are designed for flexibility and mobility, allowing them to be moved to different locations as needed. They are equipped with electric chain or wire rope hoists and can rotate 180°, 270°, or 360°, depending on the model. With lifting capacities ranging from 0.25 to 2 tons and spans up to 5 meters, they are suitable for workshops, warehouses, and areas where fixed cranes are not feasible.
3. Wall Mounted Jib Crane
Wall-mounted jib cranes are affixed directly to building columns or walls, making them ideal for facilities with limited floor space. They offer 180° rotation and are commonly used in workshops and manufacturing settings for loading and unloading materials. Standard lifting capacities range from 0.5 to 3 tons, with spans up to 10 meters.
4. Wall Travelling Jib Crane
These cranes are mounted on walls and can travel along a fixed track, combining horizontal movement with the lifting capabilities of a jib crane. They are widely used in machine manufacturing and assembly workshops. With lifting capacities from 0.5 to 3 tons and spans up to 10 meters, they provide efficient material handling along the length of a workspace.
1. Articulating Jib Cranes
Articulating jib cranes feature a multi-joint boom that provides enhanced flexibility, allowing operators to maneuver loads around obstacles and into confined spaces. They are ideal for precision tasks in manufacturing, maintenance, and assembly environments. A free-standing pedestal supports a multi-hinge boom that swings through 180° or more, providing robust coverage over a circular or semi-circular work area and handling loads up to 5 tons.
3. Portable Gantry Cranes
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.
Adjustable Height Portable Gantry Crane

- Strong yet lightweight construction for durability.
Factors to Consider When Choosing an Indoor Crane
Selecting machinery that can lift large loads is only one aspect of choosing the best indoor crane. It all comes down to matching the crane to your company's unique requirements. Making the incorrect decision might result in increased expenses, slowed operations, and even safety hazards. On the other hand, the correct decision can increase productivity, decrease downtime, and protect assets and operators. You must consider the crane's overall operating environment in addition to its basic lifting capacity in order to make an informed choice. The optimal fit depends on a number of factors, including duty cycle, headroom, power supply, and long-term serviceability.
1. Lifting Capacity
Start with a clear understanding of what you will be lifting. This includes not just the maximum load but also the typical weights you handle daily. Some loads may be long, flexible, or off-center, which creates unique stresses on the crane. Always size the system for the most demanding realistic case, not just the average lift. A crane that is too small will wear out faster and may fail unexpectedly, while one that is too large can add unnecessary costs.
2. Span and coverage area
The area that the crane needs to cover must then be reviewed. The distance between runways or the length of the space where a gantry will be used should be measured. Choose between a few smaller cranes for greater flexibility or a single giant crane. Stiffer girders, which increase weight and expense, are required for larger spans. They may restrict the height of lifts and have an impact on headroom.
3. Headroom and lifting height
Headroom often becomes a limiting factor indoors. Check the distance between the runway beam and the floor, and then calculate how much hook travel is needed. Low-headroom hoists or under-running designs can help maximize vertical clearance. For tall lifts or areas with high stacking requirements, double-girder cranes are often the better choice, since they provide extra hook height.
4. Duty cycle and operating hours
Cranes are not all made for the same level of labor intensity. Your crane needs a higher duty class if it will operate for long hours or do frequent lifts. Robust gearboxes and heavy-duty hoists are better able to withstand long-term wear and lower the likelihood of expensive malfunctions. One of the most frequent errors made when specifying cranes is to underestimate the duty cycle.
5. Precision and control needs
Smooth and accurate control is essential when working with delicate materials, molds, or parts that need to fit precisely. Operators can change speeds and stop precisely where they need to with variable frequency drives (VFDs). For production settings, sophisticated alternatives like encoder feedback or programmable logic controllers (PLCs) can provide automated or repeatable placement.
6. Hoist type and headroom
Chain hoists and wire-rope hoists have various benefits. For larger loads, greater lifting heights, and quicker speeds, wire-rope hoists perform better. For lesser loads or shorter lifts, chain hoists are affordable, portable, and simpler to maintain. Your decision should take into account the equipment's frequent use, headroom restrictions, and necessary lifting height.
7. Environmental conditions
Think about your facility's exposure to chemicals, dust, humidity, and temperature. For instance, a crane in a food industry needs to adhere to stringent hygiene regulations, whereas one in a metal shop can be exposed to abrasive dust. Anti-corrosion treatments could be necessary in humid or seaside areas. Electrical components and certified explosion-proof hoists are essential for hazardous areas.
8. Floor and structural constraints
Cranes exert significant forces on the building. Before installation, check runway supports, floor load capacity, and column layout. Free-standing cranes may need reinforced foundations to handle wheel loads, while building-mounted runways require structural verification. Overlooking this step can lead to costly retrofits or unsafe conditions.
9. Power supply and electrical requirements
Different cranes have different power needs. Confirm the voltage, phase, and available electrical capacity in your building. Some cranes use conductor bars or festoon systems, while mobile units may rely on batteries. Ensure the controls, drives, and safety systems are compatible with your power infrastructure to avoid expensive upgrades.
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.
