What Is Cribbing In Construction?

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

Cribbing is a crucial technique in construction and engineering used to provide temporary support and stability for various structures and heavy loads. It involves stacking wooden or metal components, known as cribs, to create a stable foundation or support system. In this blog, we will delve into the concept of cribbing in construction, its essential applications, and the role it plays in ensuring safety and structural integrity at construction sites.

What Is Cribbing In Construction?

Cribbing in construction is the process of stacking wooden or metal blocks, beams, or other structural components to provide support, stabilization, or elevation for structures, machinery, or heavy loads. The cribbing structure is carefully designed to distribute the weight of the object evenly, preventing shifting, tilting, or collapse, and ensuring the safety of workers and the integrity of the structure.

Applications Of Cribbing In Construction

Cribbing is employed in various construction and engineering scenarios, each requiring a unique approach to support and stability:

  1. Heavy Machinery Support: Construction sites often use cribbing to support heavy machinery, such as cranes, excavators, and bulldozers. Stacking cribs under the equipment’s outriggers or tracks helps distribute the weight evenly and prevents sinking into soft or unstable ground.
  2. Structural Support: During building construction, cribbing can provide temporary support to walls, beams, or floors when other support methods, like scaffolding or shoring, are not suitable.
  3. Rescue and Trench Shoring: In emergency situations, cribbing is used for trench shoring to prevent cave-ins during rescue operations or excavation work.
  4. Ship Dry-Docking: Cribbing is essential in shipyards to support vessels during dry-docking and maintenance. It ensures the ship remains level and stable during repair work.
  5. Aircraft Maintenance: In aviation maintenance, cribbing supports aircraft during inspections, repairs, and component replacements. It is vital for keeping the plane level and safe for maintenance crews.

Components Of Cribbing

Cribbing structures are typically constructed from solid, load-bearing components that can withstand the weight and pressure exerted on them. Common materials include:

  1. Wooden Blocks: Treated lumber or hardwood blocks are frequently used for cribbing due to their availability, ease of handling, and load-bearing capacity.
  2. Steel Beams: For exceptionally heavy loads or specialized applications, steel beams can be used to create cribbing structures. They offer added strength and durability.
  3. Concrete Blocks: In some cases, concrete blocks may be employed when resistance to moisture or extreme conditions is necessary.

Safety Considerations

Safety is of paramount importance when using cribbing in construction. To ensure a safe and effective cribbing operation, consider the following key safety measures:

  1. Proper Training: Workers involved in cribbing should receive proper training in the design and assembly of cribbing structures to ensure stability and safety.
  2. Regular Inspections: Regularly inspect cribbing structures to identify signs of wear, damage, or instability, and replace any compromised components immediately.
  3. Load Limits: Adhere to recommended load limits for cribbing structures, ensuring they are not overloaded beyond their capacity.
  4. Level Ground: Place cribbing on level and stable ground to prevent shifting or settling during use.
  5. Emergency Plans: Establish clear emergency procedures for cribbing failures and provide immediate access to equipment for cribbing removal in case of an emergency.


Cribbing is an essential technique in construction, offering a reliable method for providing support, stability, and safety in various scenarios. Whether it’s supporting heavy machinery, stabilizing structures, or facilitating emergency rescue operations, cribbing plays a vital role in the success of construction and engineering projects. By following proper safety guidelines, workers can ensure that cribbing structures are effective and dependable, ultimately contributing to the safety and integrity of construction sites and the structures being built or maintained.


What Is Cribbing In Rigging?

Cribbing is a temporary wooden structure used to support heavy objects during construction, relocation, vehicle extrication and urban search and rescue.

Why Is Cribbing Required?

Proper cribbing and blocking helps operators set up cranes or other equipment safely on a variety of ground surfaces. Blocking provides a foundation for heavy loads such as outriggers. Cribbing is used to support the outriggers at greater height than blocking can provide.

What Is The Difference Between Cribbing And Blocking?

Blocking refers to any of a number of methods for securing a machine, or part of a machine, while it is being worked on. Cribbing refers to the technique of stacking a group of uniform blocks to create a temporary, but sturdy, elevated structure capable of supporting a heavy load.

What Is A Cribbing In The Fire Department?

Cribbing is one of The mosT frequently used and. essential tools during rescue operations and is con- sidered to be among the strongest means of support. gravity is inescapable; thus, cribbing is used to transfer the weight of a load into a “footprint” and provide a simple tempo- rary support during rescue operations.
