MACLoC is the acronym for Multi-Axis Climbing Load Cells for performance analysis in sport climbing, a research team at Turin and Milan Polytechnic Universities. With the support of HBK, the team developed the prototype for a new type of “intelligent” climbing wall. Combining multi-axis force transducers and a Quantum X data acquisition system, the wall provides the climber with real-time information on his contact forces and the center of their mass.
MACLoC is the acronym for Multi-Axis Climbing Load Cells for performance analysis in sport climbing, a team of researchers and students from Turin and Milan Polytechnic Universities. MACLoC aimed to gather insights into the mechanics of climbing in order to provide athletes with detailed feedback on their training progress and the technique being used. Force measurement on the holds needed to be accurate regardless of the force application point.
Together with HBK, the project group developed the prototype for a new type of “intelligent” climbing wall, which has been registered with the European Patent Office. Combining multi-axis force transducers and a QuantumX data acquisition system, the wall provides climbers with real-time information on their contact forces and the center of their mass. These valuable insights into the mechanics of climbing allow rapid technical improvements in a highly complex and growing field of sports.
Quote from Professor Raffaella Sesana from the Department of Mechanical and Aerospace at Turin Polytechnic University. The partnership between HBK and the engineering team at Alta Scuola Politecnica has been lasting for more than three decades so far.

The measurement chain
With the help of HBM, MACLoC was able to develop an innovative climbing wall and data analysis system for faster and easier acquisition of professional and individual climbing techniques.
MACLoC (Multi-Axis Climbing Load Cells) was a project at Alta Scuola Politecnica in the framework of the 12th edition of A&T- Automation and Testing Trade Fair in Turin, Italy. Led by professors Raffaella Sesana and Daniela Maffiodo (both DIMEAS, Turin Polytechnic University) as well as Alessandro Colombo (DEIB, Milan Polytechnic University), a group of 8 students developed a technology-based approach to climbing. The sport was chosen due to its growing popularity as well as its complexity. Measurement of the contact forces and calculation of the centre of mass helps with the understanding of the mechanics of climbing, thus allows a faster optimization of technique and training sessions.
Apart from the excellent service provided during the testing and the evaluation phase of the project, the large and versatile product offering was another reason to work with HBM for this particular application. They enabled us to find a complete solution for our project. We opted for strain gauges and the MX840B module of QuantumX to develop the prototype of the sensorized climbing wall.
The QuantumX data acquisition system (DAQ) is the perfect tool for all of your test and measurement needs. For reliable data acquisition of different physical quantities and sensor technologies, QuantumX is the preferred choice. It has the unique capability to acquire any signal and sensor information.
Strain gauges (often also referred to as strain gages) are the key asset for measuring fatigue and testing materials for better and safer products. Whether it is in structural durability testing, structural health monitoring, or the production of OEM transducers, HBK's optical and electrical strain gauges are the first choice.
HBK weighing technology is synonymous with precision, safety, dependability, and quality since our load cells have set the standard for decades. The brand stands for innovative capacity, flexible and cost-effective solutions that meet virtually any customer requirement. We are also committed to the promotion and advancement of hygiene in relevant industries.
Smart products are crucial to emerging new markets - they transform the value for the end-user by providing more than core functionality. HBK creates custom OEM (Original Equipment Manufacturers) sensor solutions to deliver essential data for real-time feedback and control.
