Assembling gear sets for urban trains demands flexibility. To ensure quick changeovers of equipment, heavy wheelsets and gearing weighing up to two tonnes must be positioned precisely and securely. Thanks to the large working space coupled with a small footprint, the DEMMELER Ergonomix® M manipulator is the ideal extension to the state-of-the-art production shops. The manipulator, which boasts both angular and height adjustment capabilities, consistently moves even the highest payloads into the ideal position, thus permitting an ergonomic working posture even during heavy handling operations. The assembly operations can be carried out without fatigue and with consistently high precision. Thanks to the patented swivel range of up to 180°, the work pieces can be fully assembled in one clamping cycle without additionally having to be turned over.
