Crane Safety Requires Precision Measurements Ship to Shore

Maritime companies include businesses and governments that develop and utilize hardware to support shipyards, marine terminals, cargo and trade support, exploration and defense, fishing, aquaculture, seafood processing, commercial diving, energy infrastructure and platforms, along with marine transportation. There are multiple categories of maritime companies, including those that build ships, provide maintenance, and oversee logistics for moving an estimated 11 billion tons of goods every year.

A subset of these maritime companies operate vessels and equipment that are responsible for the transport of people and cargo. It is estimated that in the United States, maritime companies employ over 400,000 workers. They are responsible for operating, transporting, moving, and transferring equipment and materials. There is a heavy reliance on reliable cargo cranes and lifting equipment to assist workers in these functions.

Due to the nature of work, safety and regulation are key to maintaining core operations for any type of maritime transport. The work performed on the vessels, as well as on dock, rely on heavy-duty equipment that utilizes accurate measurement for performance, weighing, monitoring, and reporting. Fundamental is the durability of the sensor equipment to withstand unpredictable environmental conditions. Quality, ruggedized equipment that is durable is vital in the operations that utilize waterways to transport goods port to port. This is where Interface plays a vital role as a supplier of measurement and weighing solutions that are designed for maritime use.

One of the most common use cases for Interface Maritime solutions is in the design and operational use of cranes. Cargo handling and crane operations are considered to be one of the most dangerous maritime jobs. The unpredictable nature of onshore and offshore environments requires crane operators to function with precise and accurate measurements throughout all procedures.

Sensors and instrumentation must be able to withstand the various exposures related to maritime work, while meeting the demanding schedules for heavy lifting, as well as moving single and multiple cargo containers at a time. In these types of maritime operations, speed is also an advantage for loading and unloading vessels. Considerations of weight of the cargo and environmental condition monitoring require accurate measurement.

Crane Capacity Verification and Block Safety Monitoring

As demonstrated in the Crane Capacity Verification Application and Crane Block Safety Check Application, a customer requires a system to detect if their crane block can lift heavy loads securely, in order to keep working conditions and personnel safe at docks and other maritime transportation applications. If lifting capacities are exceeded, the customer wants a system to alarm them in real-time.


Interface products are ideal for use in heavy equipment that the maritime industry relies upon for a wide variety of equipment used to push, pull, lift, release, contain, and move things in water and on land. Wireless and environmentally protected submersible solutions are standard fare for this industry. Interface load cells, torque transducers, load pins, load shackles and tension links, as well as DAQ and instrumentation solutions provide accurate force and torque data to monitor and confirm the design and in-action processes.  To keep your instrumentation protected, inquire about our Interface Enclosures.

Interface and The Race to Space

Like many, we are celebrating some incredible milestones in the space industry this year. With every milestone, there is a long path of discovery, invention, and experience that creates these extraordinary moments.

The 53-year history of Interface is rich in experiences supplying force and torque measurement solutions to the engineers and innovators of space vehicles and the structures that support them. For decades Interface has supplied load cells, torque transducers, and multi-axis sensors of all sizes and capacities to the organizations that put the first man on the moon and to those that are pursuing the commercialization of space travel and colonization of other planets.

Our legacy as a reputable provider of sensor technologies has created a reliance on Interface products and expert calibration services. Our products have been and are used today in the development and flight qualification for the ascent and now descent of spacecraft, with rapid expansion and frequency. As we enter a new era of recoverable spacecraft, we are seeing more dependence on Interface as the supplier of the measurement devices used by these remarkable innovators, builders, and test engineers.

Why Interface? It comes down to reliability and accuracy, two extremely important measures of success in the launch and recovery of spacecraft.  These measures are also critical factors given the acceleration in space travel for both valuable cargo and with greater occurrences, humans.

Beyond the performance factors of precision force and torque measurement solutions that Interface engineers and manufactures, we are chosen by the steadfast leaders and new entrepreneurs in the space industries because of quality and our ability to customize our products to exact specifications.

You will find Interface products used in thrust testing, structural testing and even force gravity testing.  Every new test and launch inspire the Interface team to keep doing what we do. In fact, you can find our high-capacity and miniature load cells in use with future engineers and astronauts at universities around the world that are inventing new planetary exploration vehicles and rockets.  Learn more here.

Interface provides products that accurately measure thrust, which is critical in cargo lifting. Every test must be verifiably accurate due to the trustworthiness and safety requirements of moving the ever-increasing valuable payloads, which is beyond stellar communication technologies. It’s now about launching and returning humans, with frequency, in the new era of space travel.

Interface load cells are also commonly used in the production and development of launch structures.  These structures must withstand incredible forces during liftoff and return.

You can also find the Interface blue and stainless-steel load cells in the designs and for testing structures and aerodynamics for payloads of all types.

NASA’s Space Launch System (SLS) core stage is 27 feet in diameter and 200+ feet tall. Core components including liquid hydrogen and oxygen tanks must withstand launch loads up to 9 million pounds-force (lbf). Interface 1200 High-Capacity Standard Precision Low-Profile™ Load Cell Model 1260 for 600,000 lbf capacity, Model 1280 for 1,000,000 lbf capacity and Model 1290 for 2,000,000 lbf capacity were used in the design and testing of the structure.

Load cells were attached to hydraulic cylinders at various locations along test stands to provide precise test forces. Strain gages bonded to rocket structure surface and connected to data acquisition system for stress analysis. Read more here: /solutions/aerospace-industry/rocket-structural-testing/.
