Ergonomic machine loading: placing workpieces safely in machines
Making machine loading ergonomic is one of the most important levers in industrial production. Anyone who regularly loads heavy workpieces into CNC machining centers, presses, welding systems or laser cutting systems puts strain on the spine and shoulders. Manipulators up to 800 kg and the ZH90 lifting axis up to 1,200 kg take over this task without swinging and with precision.
Ergonomic machine loading: why it matters
Loading machine tools is often the most strenuous task at the workstation: heavy workpieces, precise positioning, often several times an hour and over an entire shift. When parts are loaded by hand, the risk of musculoskeletal disorders rises, as does the risk of damage to the sensitive workpiece or to the machine itself.
The German Manual Handling of Loads Ordinance (LasthandhabV) requires a risk assessment for such workstations using the key indicator method. If the risk score is high, a technical lifting aid is the most effective measure.
Typical applications for machine loading with a manipulator
CNC machining centers: load axles, shafts, housings and large components without swinging.
Presses and punching systems: position sheets and semi-finished products precisely.
Welding systems and robot cells: place components into fixtures and remove them.
Laser cutting systems: pick up sensitive plates without edge contact.
Grinding and machining lines: transfer workpieces between stations.
Benefits of swing-free workpiece loading
Swing-free machine loading combines several benefits:
Precise insertion to the millimeter, even with tight fixture tolerances.
Gentle pick-up protects the workpiece and machine components.
Shorter cycle times thanks to repeatable movements.
Significant reduction of physical strain and musculoskeletal risks.
Higher machine availability thanks to less damage.
Zeilhofer solutions for machine loading
The articulated arm manipulator guides workpieces up to 800 kg to the machine without swinging and with a large working radius. The ZH90 lifting axis lifts up to 1,200 kg on the linear Z axis, especially for heavy CNC workpieces and large castings.
The custom gripper is what counts: part-specific fixtures with magnet, vacuum, clamping gripper or special holder pick up the workpiece in a defined way and position it accurately in the machine. Quick-change interfaces allow flexibility for variants.
Ergonomics and cost-effectiveness
Ergonomic machine loading reduces sick days caused by musculoskeletal disorders, cuts scrap through precise positioning and increases throughput per shift. The investment in a manipulator typically pays for itself within 12 to 24 months at heavily used CNC or press workstations.

Frequently asked questions (FAQ)
What does ergonomic machine loading mean?
Ergonomic machine loading means placing workpieces into and removing them from machine tools with technical support instead of manual lifting. Manipulators and lifting axes guide the workpiece without swinging and position it precisely in the fixture area.
What are the benefits of ergonomic machine loading?
Less physical strain on operators, less scrap thanks to precise positioning, faster cycle times and reliable protection against damage to the workpiece and the machine.
For which machines does loading with a manipulator make sense?
For CNC machining centers, presses, welding systems, punching, grinding and laser systems, wherever workpieces from 25 kg have to be loaded manually on a regular basis.
Which loads does Zeilhofer handle in machine loading?
Manipulators up to 800 kg and the ZH90 lifting axis up to 1,200 kg. Custom grippers are matched to workpiece geometry, fixture and machine tool.
