Cantilever Jib Crane Design and Installation Options

A cantilever jib crane is a versatile and space-saving option for lifting heavy loads. It's a type of crane that uses a horizontal beam, or jib, to move loads.

One key consideration when choosing a cantilever jib crane is the type of installation. There are two main options: wall-mounted and free-standing. Wall-mounted cranes are ideal for applications where space is limited.

The wall-mounted option requires a sturdy wall to support the crane's weight and the load being lifted. This type of installation is often used in manufacturing facilities and warehouses.

Free-standing cranes, on the other hand, are more suitable for applications where there is ample space and the crane needs to be moved frequently. They are often used in construction and logistics settings.

The size and capacity of the crane also play a crucial role in the installation process. A larger crane will require a more substantial foundation and support system.

Cantilever jib cranes are a type of crane that offers flexibility and versatility in various workspaces. They're often used in industrial settings where heavy-duty lifting is required.

A typical jib crane consists of several key components, including the reach/boom, mast/pillar, movable hoist, trolley, and rotation system. 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.

The mast type jib crane is a cost-effective alternative to freestanding systems, requiring only 6” of reinforced concrete to support the crane. This type of crane can accommodate spans of 10-40 feet, capacities up to 10 tons, and 360° rotation.

Mast type jib cranes come in two types of cantilever design options: full cantilever and drop cantilever. Full cantilever designs are used when there are no overhead obstructions, providing maximum lifting capability and clearance underneath.

Here are the key design features of modern day jib cranes:

Jib cranes come in several types, each designed for specific application needs and workspace configurations.

A free standing jib crane requires a strong foundation, including footings, to support its independent structure. This allows for installation anywhere in a facility with sufficient space.

The free standing design offers a greater capacity range and longer boom span compared to wall/column mounted jibs. This makes it a versatile option for various applications.

For exterior installations, all jib crane solutions can be ruggedized for outdoor use, ensuring durability in harsh environments.

Freestanding jib cranes are a popular choice for many facilities because they can be installed almost anywhere, indoors or outdoors. They're incredibly versatile and can be used in a variety of settings.

A freestanding jib crane's independence from the building means it requires a strong foundation, typically in the form of footings, to ensure stability. This foundation is crucial for supporting the crane's load during a lift.

These cranes can accommodate spans of up to 50 feet and capacities of up to 15 tons, making them suitable for a wide range of applications. They also offer 360° of rotation, allowing for smooth and efficient movement.

There are three main designs for freestanding jib cranes: Base-Plate Mounted, Foundation/Insert Mounted, and Sleeve-Insert Mounted. Each design has its own unique installation process and benefits.

Here are the key differences between these designs:

Freestanding jib cranes offer the highest capacities, longest spans, and greatest amount of rotation compared to other jib crane systems. However, they are also the most expensive and permanent setup due to the special foundation required to anchor and secure the crane.

Foundationless jib cranes are a great option for facilities that need a freestanding jib crane without the hassle of a special poured foundation. They can be slab-mounted and bolted to 6″ reinforced concrete for indoor use.

These jib cranes are incredibly fast to install, as you don't have to wait for a poured concrete foundation to cure. This speed of installation is a major advantage, especially in facilities where time is of the essence.

Typically, foundationless jib cranes can accommodate a range of sizes and capacities, including 9-16′ spans, capacities up to 1,000 lbs, 360° rotation, and boom heights up to 20′.

They're also super portable, as they can be easily relocated within a facility if needed. This flexibility makes them a great choice for facilities that need to reconfigure their layout or move equipment around.

When choosing a jib crane, one of the most important decisions is the mounting type. There are two main options: wall-mounted and free-standing.

Wall-mounted jib cranes are a great space-saver, as they don't require any type of floor or foundation support. This makes them ideal for workstations where space is limited.

Wall-mounted jib cranes can be designed to swing around obstacles, under obstructions, or fold out of the way of overhead cranes. They can accommodate spans ranging from 8-30’ and capacities up to 5 tons.

The two main types of wall-mounted jib cranes are cantilever and tie-rod supported. Cantilever jib cranes offer the greatest amount of clearance, above and below the boom, while tie-rod supported jib cranes are the most economical means of providing hoist coverage.

A cantilever jib crane's design and installation are crucial to its functionality and safety. The basic design and construction of jib systems make them simple to operate and require less maintenance.

Jib cranes typically have a few key components, including the reach/boom, mast/pillar, movable hoist, trolley, and rotation. The trolley's motion 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.

The rotation of the boom is a vital aspect of a jib crane's design, with freestanding and mast type jib cranes offering 360° of boom rotation, and wall and column-mounted jib cranes offering 180-200° of rotation.

You'll need to consider electrification/pneumatic power options, such as electric collector rings or pneumatic air lines, to provide rotation assistance and allow for continuous 360° boom rotation.

The controls of a motorized or air-powered jib system can be managed using a push button controller, which allows for control over the rotation of the boom, as well as the motion of the trolley and the lifting and lowering motion of the hoist.
