The confined conditions make it necessary to strike a balance between speed and reliability. The focus here is on precision and reliability of the machine without the machine's jib touching the container and thus getting damaged. While the container width is standardized, the height of the container (standard or large-area) determines the machine's operating space.
The gear units used, including the shaft-mounted helical-bevel gear units for installation in confined spaces, are largely low backlash. Precise positioning is therefore ensured. DRL../DR2L.. series asynchronous servomotors (the energy-saving IE3 designs) are used for larger loads. They have a greater inherent mass moment of inertia than conventional synchronous motors, making them ideal for installation in applications where a balanced inertia ratio between the load and motor is desired for control reasons.
