leantechnik0317Assembly production in the automotive industry is highly efficient and in a tight time cycle. Precondition for this is the precise and fast delivery of the components at the assembly sites. A manufacturer of electric cars therefore ordered a larger number lifting tables From Leantechnik, with which the car bodies are positioned very precisely and in the shortest time in the right position for the further processing by robots.

The requirements of the car manufacturer for the lifting tables were high: in addition to very high accuracy, low maintenance costs and a long service life were also included. The manufacturer even exceeded the requirements set by the customer. A further production line with the products of the rack and pinion gear specialists is already being planned.

The basis of the lifting tables are "Lean SL 5.3" rack-and-pinion gearboxes, which allow speeds of up to 0,6 m / s with a maximum lifting force of 8000 N. Two servomotors drive the rack-and-pinion gear units with a round-guided rack. This transmission variant is very well suited for simple synchronous movements in which there is no or only a small transverse force absorption. Thanks to their large diameter of 60 mm and the wide toothing of the tooth rod, the Lean SL gear units 5.3 have a high flexural stiffness. This is an important prerequisite to be able to safely and precisely lift the weight-bearing devices for the bodyshells to their intended position.
