What Is A Spreader Bar?

Are you curious to know what is a spreader bar? You have come to the right place as I am going to tell you everything about a spreader bar in a very simple explanation. Without further discussion let’s begin to know what is a spreader bar?

In the world of rigging and lifting, specialized tools and equipment play a crucial role in ensuring safe and efficient operations. Among these tools, the spreader bar stands out as a versatile and indispensable lifting solution. Spreader bars, also known as lifting beams, are essential devices used to evenly distribute the load weight and stabilize lifted objects. In this blog, we will explore the concept, design, and applications of spreader bars, highlighting their significance in various industries and the role they play in safe lifting practices.

What Is A Spreader Bar?

A spreader bar is a rigid, horizontal device typically used in conjunction with lifting slings and cranes to lift and move heavy loads. It consists of a straight, horizontal beam that incorporates multiple lifting points or attachment points. The purpose of the spreader bar is to maintain a uniform balance while lifting heavy or awkwardly shaped objects, preventing tipping, tilting, or damage to the load during the lifting process.

Design And Components

Spreader bars come in various designs and sizes to accommodate different lifting requirements. The key components of a typical spreader bar include:

  1. Main Beam: The main beam is the horizontal section of the spreader bar. It is usually made of sturdy materials such as steel or aluminum to withstand heavy loads and ensure structural integrity.
  2. Lifting Points: Spreader bars are equipped with multiple lifting points along the main beam. These lifting points are where the lifting slings or chains are attached to secure the load.
  3. Rigging Hardware: The lifting points may feature shackles, hooks, or other types of rigging hardware to facilitate easy attachment to the load and the lifting equipment.
  4. End Caps: Many spreader bars have end caps or pads at the extremities of the main beam. These caps provide additional protection to the lifted object and help distribute pressure evenly during the lifting process.

Applications Of Spreader Bars

Spreader bars find applications in a wide range of industries and lifting scenarios:

  1. Construction and Manufacturing: In construction sites and manufacturing facilities, spreader bars are used to lift and move heavy building materials, machinery, and large industrial components.
  2. Oil and Gas Industry: The oil and gas sector utilizes spreader bars to handle heavy equipment and loads on offshore rigs, ensuring safe and efficient operations.
  3. Maritime and Shipping: In port and maritime operations, spreader bars are employed for container lifting and handling during loading and unloading operations.
  4. Aerospace: In the aerospace industry, spreader bars are used to lift and position aircraft components, engines, and other large structures.

Safety Considerations

While spreader bars are essential tools for lifting heavy loads, their usage requires careful planning and adherence to safety protocols. Some critical safety considerations include:

  1. Weight Capacity: Always ensure that the spreader bar’s weight capacity matches or exceeds the load being lifted. Overloading can lead to catastrophic failures.
  2. Load Distribution: Properly position the lifting points on the spreader bar to evenly distribute the load weight. This helps prevent tilting or shifting of the load during lifting.
  3. Inspection and Maintenance: Regularly inspect spreader bars for signs of wear, damage, or deformation. Perform maintenance and repairs as needed to ensure their continued safety and functionality.


Spreader bars are indispensable tools in the world of lifting and rigging, offering a safe and efficient means of handling heavy loads across various industries. Their ability to evenly distribute weight and stabilize loads makes them essential for lifting tasks involving bulky or irregularly shaped objects. When used correctly and in accordance with safety guidelines, spreader bars contribute significantly to the smooth execution of lifting operations, promoting workplace safety and productivity.

What Is The Purpose Of A Spreader Bar?

A spreader bar allows the user to attach the load at two points. This evenly spreads the load throughout the bar and wire rope slings and make it easier to lift. Moreover, the attachment points are positioned so that the bars seamlessly allow vertical hoists.

What Is The Difference Between A Spreader Bar And A Lifting Bar?

As a broad distinction, in their purest forms: Spreader beams are mainly subject to compressive stress and are lifted using a two-legged sling at the top. Lifting beams are mainly subject to bending stresses and are lifted from a central lifting lug.

What Is The Advantage Of Spreader Bars?

Spreader bars help keep things organised by distributing the weight evenly across their length, which reduces strain on your equipment while also preventing damage from happening accidentally due to uneven loading patterns caused by other parts (like forks).

What Is A Spreader Bar Rigging?

Spreader bars for lifting and rigging consist of a beam with two or more lifting lugs on the bottom that attach to lifting slings that attach to the load. How they differ from lifting beams is in their top attachment.
