Designing ergonomic machine loading is one of the most important factors in industrial manufacturing. Anyone who regularly loads heavy workpieces into CNC machining centers, presses, welding systems, or laser cutting machines puts strain on their spine and shoulders. Manipulators up to 800 kg and theHub axle ZH90Up to 1,200 kg, this task is performed smoothly and precisely.
Ergonomic machine loading: why it matters
Loading machine tools is often the most strenuous task in the workplace: heavy workpieces, precise positioning, often several times an hour and throughout an entire shift. Manually loading components increases the risk of musculoskeletal disorders and damage to the delicate workpiece or the machine itself.
The manual handling regulations stipulate a risk assessment for such workplaces using the key indicator method. Where the risk is high, technical lifting aids are the most effective measure.
Typical applications for machine feeding withmanipulator
CNC machining centers: Inserting axes, shafts, housings and large components without pendulum motion.
Presses and stamping machines: Precisely positioning sheet metal and semi-finished products.
Welding systems and robot cells: Components inDevicesinsert and remove.
Laser cutting systems: for handling delicate plates without edge contact.
Grinding and machining lines: Transferring workpieces between stations.
Advantages of pendulum-free workpiece loading
A pendulum-free machine loading system offers several advantages:
Precise insertion in the millimeter range, even with tight recording tolerances.
Gentle handling protects the workpiece and machine components.
Shorter cycle times through reproducible motion sequences.
Significant reduction in physical strain and musculoskeletal risks.
Increased machine availability due to less damage.
Zeilhofer's solutions for machine feeding
The Joint manipulatorIt guides workpieces weighing up to 800 kg smoothly and with a large working radius in front of the machine. The ZH90 lifting axis lifts up to 1,200 kg on the linear Z-axis, especially useful for heavy CNC workpieces and large castings.
The key is the individual gripper: component-specific devices with magnets, vacuum grippers, clamping grippers, or special holders precisely pick up the workpiece and position it accurately in the machine. Quick-change interfaces allow for flexibility in terms of product variants.
Ergonomics and cost-effectiveness
Ergonomic machine loading reduces downtime due to musculoskeletal disorders, minimizes rejects 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 refers to the insertion and removal of workpieces into machine tools with technical support instead of manual lifting work.Manipulators and lifting axesThey guide the workpiece without pendulum motion and position it precisely in the receiving area.
What are the advantages of ergonomic machine loading?
Less physical strain on operators, reduced rejects through precise positioning, faster cycle times and reliable protection against damage to the workpiece and the machine.
For which machines is feeding with a manipulator useful?
For CNC machining centers, presses, welding systems, punching machines, grinding and laser systems, anywhere where workpieces weighing 25 kg or more need to be manually loaded on a regular basis.
What loads does Zeilhofer move when loading the machines?
Manipulators up to 800 kg and the ZH90 lifting axis up to 1,200 kg. Individual grippers are tailored to the workpiece geometry, fixture, and machining center.
