Innovative horizons

Cranes are general-purpose lifting equipment widely used in construction industries. Crane operators must operate multiple levers simultaneously while checking the position of the load visually. In addition, cranes are affected by the boom deflection and wind, so it takes a long time to become a proficient crane operator. On the other hand, the number of skilled crane operators in Japan is declining due to the aging population. Taking the cognizance of the matter, DeepX and Tadano have started a joint research project of crane automation utilizing AI technology. The aim of this project is to improve safety at work sites by simplifying and automating mobile crane operations by utilizing AI technologies.

Mobile cranes are known to be one of the most difficult machines to operate on construction sites. Slewing and elevating motion in mobile cranes typically generates undesirable two-dimensional load-sway; therefore, crane operators must be highly skilled to suppress this sway upon completion of the point-to-point crane manoeuvre. DeepX and Tadano have therefore developed a control algorithm based on AI technology, leveraging simulator environment for controller optimization. Using this algorithm, the operator can safely and accurately move the load to the desired position while suppressing load sway.

Konecranes’ advanced technology provides high mechanical and electrical efficiency which reduces the crane’s overall energy consumption. Smart Features and process automation improve productivity, and further reduce energy consumption. For example, a fully automated crane with Konecranes DynAReg regenerative braking can recapture up to 30% of the crane’s braking energy, helping to decrease the overall energy consumption.

Manitowoc continues its expansion and investment in support services with the launch of CONNECT, a new digital platform launched at bauma 2022.

The future of construction is high-tech and interconnected. That is why in addition to hardware product innovations, PALFINGER is increasingly using smart solutions that set new standards. The innovative Smart Control to control the crane tip unites the crane with the operator and revolutionizes the work process. Instead of moving up to three different levers, Smart Control only requires one to move the crane tip horizontally or vertically. The operator therefore only needs to specify the direction of the crane tip, while the intelligent technology combines the necessary crane movements to reach the target position exactly.

However, precision is required not only for crane control. The work steps involved in loading and unloading containers also require precision down to the last millimeter. Since container handling is one of the biggest challenges in everyday working life, PALFINGER has taken this on and developed an intelligent assistant system — Smart Loading Assist. The latest version of this semi-automatic system was displayed for the first time at bauma 2022. The Smart Loading Assist adds a 3D camera system, sensors and a high-performance computing unit to the hooklift. It works in a similar way to optical parking sensors and helps the operator to correctly position the hooklift in relation to the container. The integrated Obstacle Detection solution identifies any obstacles, or people, in the hazardous area and immediately warns the operator. The Smart Loading Assist also provides effective support during the unloading process to protect the surface on the ground, and the container.

A Triton study highlighted that growing trends in high-performance goods with lower carbon emissions and fuel economy have pushed companies to reinvent their product line and expand their presence in the mobile crane market. The increased eco-consciousness among manufacturers encourages the installation of flexible hydraulic systems and multimode power output functions. This helps reduce crane fuel consumption and makes them more responsive to changing trends. As mentioned in one of Konecranes’ technical insights, “New, smaller cranes are also designed to be more energy efficient. New crane technology cycles energy back into the power grid, which greatly mitigates warehouse energy consumption and costs. Some cranes are even manufactured with recyclable materials, supporting a company’s goal of being more environmentally responsible.” With all these interesting developments in the offing, the cranes market is poised for a great leap ahead.
