Outlining Force Solutions for Structural Outrigging

Across a wide variety of industries, heavy machinery, maritime, construction, and other infrastructure often need additional structural support. This includes support that prevents equipment, vessels, and buildings from falling over, capsizing or collapsing.

Typically, the solution to provide this critical structural support comes in the form of an outrigger. For vehicles, both land and maritime, an outrigger is a projecting structure, with specific meaning depending on types of vessels, or the legs on a wheeled vehicle that are folded out when it needs stabilization.

For buildings, outriggers are interior lateral structural systems provided to improve the overturning stiffness and strength of high-rise buildings. It is a lateral load resisting system that is located within the building. The whole system consists of a core structure connected to the perimeter columns of the building.

These types of structural supports became popularized in the 1980s as an addition to high-rise buildings as they are effective up to 150 floors due to its unique combination of architectural flexibility and structural efficiency. Outrigging has been adapted for large vehicles and boats, such as large cranes that are extremely top heavy and can create balance problems, or yachts that need to be stabilized when stored out of water.

With the addition of these supports, various forms of testing need to be done to ensure the outrigger can support the vehicle or structure it is installed upon. This is where Interface’s force measurement testing and monitoring products are utilized in different outrigging applications.

Interface load cells are used by outrigging engineers, civil engineers and heavy equipment manufacturers, oil and gas, construction industry and marine equipment companies. Read more why Rigging Engineers Choose Interface Measurement Solutions.

The role of force measurement sensor technologies in outrigging is to provide high accuracy measurement of the outrigging equipment in test and actual use. The applications range from integration of sensors into outrigger equipment, to load cells for real-time monitoring of the physical structure using outrigger supports.

The most common Interface products used for outrigging include:

For example, Interface load shackle cells are used to measure the forces during outrigger testing as well as on the outrigger equipment that support the structure. The data from the sensor is critical information used to assess the structural integrity of the outrigger or structure and to identify any potential weaknesses.

Interface load cells, such as our load shackles or load pins, are typically placed in strategic locations on the outrigger or structure where the force is expected to be greatest. The load cell is then connected to a data acquisition system (DAQ) or indicator that records the force readings. The data can then be analyzed to determine the maximum force applied to the outrigger or structure, as well as the distribution of force over the structure.

Load cells can also be used to monitor the performance of outriggers or structures over time. This can be helpful in identifying any changes in the structural integrity that may be caused by wear and tear, environmental factors, or other factors. Utilizing instrumentation with alarm capabilities is helpful, as well as a tool for maintenance.

Load cells are an important safety feature in outrigging equipment. They can help to prevent accidents and ensure that the equipment is used safely. A load cell is used to prevent a crane collapse during the construction of a high-rise building in a large congested metropolitan city. The crane is used for lifting a heavy beam. The load cell alerts the operator when the load is too heavy.

Ultimately, force measurement provides several benefits to testing and monitoring different outrigger applications, including:

  • Increased safety: By measuring the force applied to the outrigger, a load cell can help to prevent overloading and damage to the outrigger. It is also valuable for continuous monitoring during lifting use cases, such as with a crane or heavy machinery.
  • Improved efficiency: By monitoring the performance of the outrigger, a load cell can help to identify any potential problems early on, which can help to prevent costly downtime.
  • Reduced risk: By providing accurate data on the force applied to the outrigger, a load cell can help to reduce the risk of accidents and injuries.

Examples of how force measurement is used to test outrigger solutions in a variety of industries:

  • In the oil and gas industry, load cells are used to test the outriggers of offshore drilling rigs. This helps to ensure that the rigs are safe to operate in high-wind and wave conditions.
  • In the construction industry, load cells are used to test the outriggers of cranes and other lifting equipment. This helps to ensure that the equipment is safe to use and that it will not overload the outriggers.
  • In civil engineering, load cells are used to test the structural integrity of bridges and other structures. This helps to ensure that the structures are safe to use and that they will not collapse underload.

Outriggers play a critical role in the safety and support of vehicles, infrastructure projects and massive structures. Interface force measurement products also play a necessary role in safeguarding outriggers and the operators.

Rigging Engineers Choose Interface Measurement Solutions

Interface supports rigging engineers who design, plan, and oversee the rigging of heavy loads by providing high accuracy measurement solutions. Rigging is the process of using ropes, chains, and other lifting equipment to move and position large objects.

Rigging engineers typically work in maritime, construction, manufacturing, entertainment and energy industries. Interface is also seeing a growing demand for sensor technologies used by rigging engineers that work in aerospace, both for aircraft and space vehicle manufacturers.

The use of load cells to measure the weight of heavy loads, such as cranes, ships, rockets, theater equipment and machinery is on the rise. Rigging engineers use the data from load cells, load pins, load shackles, and tension links to ensure that the loads are not overloaded and that the rigging systems are properly designed for each use case. This often requires pairing the high accuracy sensor with instrumentation. For versatility wireless telemetry systems are useful for rigging engineers.

These vital engineering positions are responsible for rigging up and down cranes, loading and unloading ships, or moving heavy equipment around a factory floor. Rigging engineers that design and plan rigging systems for lifting and transporting heavy loads across various industries rely on accurate measurement data. They often oversee the rigging of heavy loads, ensuring that it is done safely and efficiently. They inspect rigging equipment for wear and tear, and make repairs as needed while maintaining records of rigging operations. Sensors and instrumentation play an important role.

Load cells are an important tool for rigging engineers. They provide valuable information that can be used to ensure the safety of rigging operations, whether they are for mooring tension tests in the maritime industry or for lifting an aircraft for wind tunnel testing. Load cells can be used in a variety of ways by rigging engineers. For example, they can be used to:

  • Monitor the weight of a load in real time. This information can be used to make sure that the load does not exceed the safe lifting capacity of the rigging system. Sensors are often integrated into conveyor systems, hoppers, and other equipment to measure the weight or force being exerted. These devices are often used in industries like mining, agriculture, and manufacturing.
  • Create a load map. A load map is a visual representation of the weight distribution of a load. This information can be used to ensure that the load is evenly distributed, and that the rigging system is properly designed no matter the size of structure or component.
  • Set overload limits. Overload limits are set to prevent the rigging system from being overloaded. If the weight of a load exceeds the overload limit, an alarm will sound, and the rigging system will be shut down.
  • Record load data. Load data can be recorded and used to track the weight of loads over time. This information can be used to identify trends and patterns that may indicate a need for maintenance or repairs.
  • Secure equipment. The information from force and weight sensors is critical when lifting and securing equipment, such as appartus used in the entertainment sector, from arial arts rigging to stage set-up.

Hydrofoil Testing in a Wave Tank

Hydrofoil design for watercraft is a delicate balance between performance and complexity. Finding the right shape without using overly complex angles to achieve the desired amount of lift is crucial when designing a successful hydrofoil. Once an engineer’s concepts are ready for testing, using the best force measurement equipment is required to sense the subtle differences between hydrofoil designs. Lift and drag are the most important characteristics of a hydrofoil. The Interface Model 3A120 3-Axis Load Cell is needed to read these forces. The Fz senses lift and the Fx and Fy sense the drag. Using a model BSC4D-USB bridge amplifier increases the visibility of the load cells output signals. When using the load cell and bridge amplifier, the engineers can record the real-world lift and drag forces the hydrofoils are having on the watercraft. This data allows a more in-depth comparison of proposed hydrofoil designs to find the best model for the job. Learn more.
