In Eltville am Rhein, Jean Müller develops and produces around 40,000 components for distributing, controlling, securing and measuring electrical energy in low-voltage networks. For handling particularly heavy punch-press tools for manufacturing a new product series, the family-run business was initially looking for a new transport cart. In the end, however, the company acquired a complete die-changing system from Roemheld, comprising racking and a lifting cart with integrated docking system and radio remote control. Similar technology is available in Britain and Ireland through Roemheld UK.

A the heart of the joint solution is the manoeuvrable, electrically-driven Roemheld RWA 4000 die-changing cart, which is capable of carrying a load of up to 4 tonne. It has a die-changing table with integrated hydraulic ball bars and a pull-push system that facilitates automatic insertion of the dies on a press bed.

During transport, the hydraulic balls in the cart table are lowered and, consequently, the die is prevented from slipping. A safety circuit ensures that the RWA 4000 only moves when the ball bars are retracted. Removable safety bars at the front and sides of the support surface additionally secure the die. Users can control the cart from a central panel on the drawbar, on which a multi-function display sits. Alternatively, employees can adjust the most important cart functions remotely via the radio control.

Jean Müller’s new system has been in continuous three-shift operation since the spring of 2022, the year that the company celebrated its 125th anniversary. The distances the dies have to travel to the presses is now shorter, resulting in a time saving of 15 minutes for each changeover, which happens up to three times per shift.
