Many cranes have been in use for 50 years or more. Despite the fact that this number sounds high, many manufacturers at that time produced very massive and high-quality cranes, which still perform their function well and will continue to do so in the future.
.Especially with the use of frequency inverters, the usability of the crane is greatly increased, and due to lower shocks, the service life of mechanical components is increased. Switches and sensors are also available today, which can greatly increase safety.
It makes sense to renovate such cranes, because for only a fraction of the price of a new process crane, we get an crane that will perform its tasks efficiently for another 20 or 30 years.
