The Jumbo drive unit uses a relatively cheap steel cable, as a result of which the maintenance costs on moving parts are low. Therefore, return on investment for larger barns with long passages is quick. The system has been designed to be used extensively.
It protects the steel cable from excessive strain, therefore the service life of the cable is extended considerably. Within the casing there is a drum, which unwinds the cable at one end and winds it up at the other end.
