Advanced semi-automatic crane for transport of accommodation units in the warehouse

With our valued Austrian customer Kaufmann Bausysteme GmbH a problem arose in the planning phase of a new production section for accommodation units near Graz: how to lift and drop off an accommodation unit (residential module) without the help of the human factor.
In all previous cranes at this client, an employee had to climb on the residential module and,, with the help of chains, load ropes or other means attach the accommodation unit to the crane traverse. Since a warehouse was planned up to 3 units heigh, doing so would be extremely demanding, time consuming, and dangerous.

At Insem – Atmos, we have developed a special traverse similar to that for shipping containers, only with a slightly different way of attaching to the load. The traverse is equipped with four claw arms that grab the screws on the accommodation unit specially made for this purpose. In addition, it is equipped with a video system with which the operator can see and monitor what is happening during the load transfer. The  sensors in the claw arms ensure that the accommodation module is securely gripped and ready for further transport. Control is performed semi-automatically from the control room or with a radio control with the MS Surface plate installed, and visualisation of the warehouse with all the key data on the location of the unit, weight, condition of the sensors,… live

The warehouse itself is suitable for storing up to 200 accommodation units with a maximum size of 12 x 3.5m.

The client’s wish was to handle the cargo semi-automatically, so the initial collection and final disposal of the load is done manually with a command, and all other movements are done automatically.

Example: When the operator manually picks up an unit that has arrived from a production site, he selects the desired disposal location on the operation plate. The crane drives the unit to the desired location and then stops at a height of 2m above the ground or above the existing and already stored unit. The final descent is performed by the operator, using the camera and the sensor display.

With the new mode of transport of accommodation units, 1 transport cycle lasts up to 3 times less than with the method with chains or strips, making the whole process much safer and requiring fewer people.
