International trade is growing steadily each year and this fact increases dramatically the number of commercial exchanges. In the port industry, ships are growing bigger to carry more containers in each shipment to reduce fuel consumption applied to each TEU. Therefore, logistics operators need bigger port cranes with better operational features. R&D initiatives in port cranes are aimed to have higher, faster, more efficient and safer cranes. The development of communications technology helps to implement remote control systems in this new generation cranes.
Automatic crane system – Coordination through remote control technology
The trend is to implement an automatic crane system in ports with the following advantages:
Ergonomic: The operators don’t need to stay in the crane cabins far above the ground and they can stay in a control room more comfortably following up the operations. This shall improve physical pain, postural sickness and as consequence absenteeism of employees.
Productivity: The automatic features of the cranes run the loading and offloading operations through a real time control system based on accurate positioning of vehicles, remote cameras procedure surveillance, real time pendulum motion correction, high-accuracy landing and optimized stowage plan for the shipments. All this features implemented within a real time control system that manages smartly all this inputs, allows the port cranes to perform a more efficient, accurate and faster loading & offloading operation.
Safety: The number of people involved in the lifting operations is decreased dramatically as the remote control technology improves. Thus, safety is highly positive impacted as prevention of accidents due to fall of loads onto people.
Remote Hooking – Mandatory feature of a remote control crane
The automatic cranes shall have an automatic lifting hook to ensure an accurate, quick and safe hook on/off operation by remote control. The automatic hook, as the elebia auto-hook solution, generates a magnetic field that couples to the ring or other fixing device and closes the hook, by remote control which is secured by cryptographic keys to avoid non-intended use or malicious uses. This hooking system shall work properly, quickly and safely as a fundamental part of the automatic crane system to ensure the good performance of the whole system. Therefore, it is mandatory to choose a reliable auto-hook solution as elebia hooks.
