On July 24, 2019, the pre-acceptance of a completely pre-assembled crane 4t + 4t with a span of 9.5m took place. The crane was manufactured in cooperation with a company Nopo Engineering for a global manufacturer of concrete building elements. This is a demanding application because the crane is utilized for permanent transport of concrete elements to the dryer shop. On this way the SLT technology complemented the existing Demag crane which enabled to the end user significantly increasing of the production capacity. The crane is equipped with Stahl hoists and allows working with or without suspended traverse. The spring cable reel produced by Hartmann&König is in this case used for power supply to the traverse. In the following days after the pre-accepatnce the crane was successfully installed and put into operation.
