Frequently heavy loads can only be transported by several people and with tremendous effort. As a consequence people often suffer sooner or later from having lifted heavy loads the wrong way. The Cargomaster motorized stair climbers by AAT Alber Antriebstechnik GmbH, developed as a result of a practical need, offers relief at precisely this point. Your transportation personnel is physically relieved a great deal, which, in turn, relieves your wallet because our machines reduce or avoid absences due to back injuries or slipped disks.
