A jib boom crane is a versatile and efficient piece of equipment that can be used for a variety of tasks, from construction to manufacturing.
There are several design options to choose from, including fixed jib cranes, slewing jib cranes, and pendant jib cranes.
Each type of crane has its own unique benefits and is suited for specific applications.
Design and Components
A jib boom crane's design and components are surprisingly straightforward. The basic design is simple, requiring less maintenance compared to other types of cranes.
The main components of a jib system include the reach/boom, mast/pillar, movable hoist, trolley, and rotation. The reach/boom is the horizontal beam that the trolley travels back and forth on, while the mast/pillar supports the boom on freestanding and mast systems.
The trolley carries the hoist, wire rope or chain, and the hook along the entire length of the boom, with the motion of the trolley being manual, motorized, or pneumatic. Rotation is possible on freestanding and mast type jib cranes, achieving 360° of boom rotation, while wall and column-mounted jib cranes can achieve 180-200° of rotation.

Here are the main components of a jib system:
- Reach/Boom – the horizontal beam that the trolley travels back and forth on.
- Mast/Pillar – the vertical beam used to support the boom on freestanding and mast systems
- Movable Hoist – the hoist is used to lift, position, and lower a load.
- Trolley – the motion of the trolley can be manual, motorized, or pneumatic.
Components
A jib crane's components are actually quite straightforward. The main parts include the reach/boom, mast/pillar, movable hoist, trolley, and hook.
The reach/boom is the horizontal beam that the trolley travels back and forth on. This is where the magic happens, and the crane can lift heavy loads with ease.
The mast/pillar is the vertical beam that supports the boom on freestanding and mast systems. It's a crucial part that keeps the crane stable and secure.
The movable hoist is used to lift, position, and lower a load. It's typically carried by the trolley, which moves along the boom.
The trolley can be manual, motorized, or pneumatic, and it carries the hoist, wire rope or chain, and the hook along the entire length of the boom. This is what allows the crane to lift loads with precision.
On freestanding and mast type jib cranes, you can achieve 360° of boom rotation. On wall and column-mounted jib cranes, you can achieve 180-200° of rotation.

You can add electrification/pneumatic power to the top or bottom of the mast to provide rotation assistance and allow for continuous 360° boom rotation.
The controls on motorized or air-powered jib systems can be as simple as a push button controller to control the rotation of the boom, as well as the motion of the trolley and the lifting and lowering motion of the hoist.
Here are the main components of a jib crane in a list for easy reference:
- Reach/Boom
- Mast/Pillar
- Movable Hoist
- Trolley
- Rotation (360° or 180-200°)
- Electrification/Pneumatic Power
- Controls
The hook height of a jib crane is also an important consideration. You'll need to know the lowest overhead obstruction to determine how tall your jib crane can be.
A rotation stop can be added to limit the crane's motion before it collides with a nearby object, especially if it's located close to a wall or other obstruction.
For outdoor applications, the components of the jib system can be galvanized to resist corrosion. This is a great option if you're planning to use your crane in harsh environments.
Mast Type
Mast type jib cranes are a cost-effective alternative to freestanding systems. They don't require a special foundation, just 6” of reinforced concrete to support the crane.
Typically, mast type jib cranes can accommodate spans of 10-40 feet, capacities up to 10 tons, 360° rotation, and boom heights up to 40 feet. These cranes are similar to freestanding systems and can be used for heavy-duty/high-productivity applications.
There are two types of cantilever design options: Full Cantilever and Drop Cantilever. The Full Cantilever design is used when there are no overhead obstructions, while the Drop Cantilever design allows for clearance for overhead obstructions located below the top of the mast.
Mast type jib cranes can be mounted to the building's floor and steel beams, providing full 360-degree rotation. This setup is highly versatile and can be used in various industrial applications.
American Equipment offers mast type jib cranes in full cantilever and drop cantilever jib crane styles. Their mast style jib cranes are available with standard lifting capacities ranging from 0.25 to 5 tons, heights up to 20 feet, and spans up to 20 feet.
Here are the key specifications of mast type jib cranes:
- 10-40’ spans
- Capacities up to 10 tons
- 360° rotation
- Boom heights up to 40’
Types of Systems
There are several types of jib crane systems available, each with its own range of capabilities and design options.
Mast type jib cranes are a cost-effective alternative to freestanding systems, requiring only 6” of reinforced concrete to support the crane. They can accommodate spans of 10-40’, capacities up to 10 tons, and 360° rotation, with boom heights up to 40’.
Articulating jib cranes have two swivel arms that can lift loads around corners and columns, and reach into or under machinery and containers. They offer a greater coverage area and more flexibility closer to the mast or column.
Mast type jib cranes can be used for heavy-duty/high-productivity applications, but they do require an overhead beam or support structure to provide support in addition to the foundation.
Here are some key differences between mast type and articulating jib cranes:
Installation Options
When choosing a jib boom crane installation option, consider the space and structural requirements of your facility.
Freestanding jib cranes can be installed virtually anywhere, including indoors or outdoors, and can accommodate spans up to 50' and capacities up to 15 tons.
There are three main designs for freestanding jib cranes: Base-Plate Mounted, Foundation/Insert Mounted, and Sleeve-Insert Mounted.
These designs vary in terms of how they can be mounted and installed, but all offer flexibility and customization options to suit your needs.
The following table outlines the main characteristics of each design:
Wall-mounted jib cranes, on the other hand, offer space-saving benefits and can be installed close to ceilings or walls, but may require structural engineering approval prior to installation.
Free Standing
Free standing jib cranes offer the flexibility of being installed virtually anywhere, with no placement limitations. They can be used in open areas or small workstations, indoors or outdoors.
Freestanding jib cranes can accommodate spans up to 50 feet and capacities up to 15 tons. They also offer 360 degrees of rotation and boom heights up to 40 feet.
There are three main designs for freestanding jib cranes: Base-Plate Mounted, Foundation/Insert Mounted, and Sleeve-Insert Mounted. Each design has its own advantages and can be used depending on the specific needs of the installation.
The Base-Plate Mounted design is the easiest to install and the most popular, but it requires a reinforced concrete foundation. The Foundation/Insert Mounted design eliminates the need for gussets, while the Sleeve-Insert Mounted design allows for relocation of the jib system without damaging the mast.
Free standing jib cranes can be used underneath bridge cranes or in open areas where the crane can serve several workstations. They help make the most out of available space, improving efficiency and increasing productivity throughout a facility.
Here are some specifications of free standing jib cranes:
- Standard 0.25 to 5 ton lifting capacity
- Standard 8 to 20 feet spans
- Top or bottom entry for 360° boom rotation
- Optional power rotation
Foundationless jib cranes are another type of freestanding jib crane that can be installed almost anywhere in a facility. They are slab-mounted and bolted to 6″ reinforced concrete for indoor use.
Wall-Mounted
Wall-mounted jib cranes are a great space-saving option for factories and warehouses. They can be installed very close to the underside of the lowest ceiling obstruction, providing maximum clearance both under and above the boom.
These systems can be designed to swing around obstacles, under obstructions, or fold out of the way of overhead cranes to ensure no interruption of production. A wall-mounted cantilever jib crane offers the greatest amount of clearance, above and below the boom, and has a full-cantilever design.
Wall or column-mounted jib cranes can accommodate spans ranging from 8-30 feet and capacities up to 5 tons. They can also rotate 180°-200°.
Wall-mounted jib cranes can be designed to mount to a wall or building support column in two different ways: cantilever or tie-rod supported. The tie-rod supported design is the most economical means of providing hoist coverage along walls or building columns.
Here are some key specifications for wall-mounted jib cranes:
- Spans: 8-30 feet
- Capacities: up to 5 tons
- Rotation: 180°-200°
These types of jib systems are among the most economical in price and design, but they do have some limitations, including not allowing for full 360° of rotation.
