Whether it's a lifting axis or a manipulator, both systems guide heavy loads smoothly and ergonomically. The choice depends on the primary direction of movement: those who mainly need to lift vertically choose the lifting axis with a linear Z-axis up to 1,200 kg. Those who move loads in a space with a large working radius choose theJoint manipulatorUp to 800 kg. This article outlines the decision criteria.
The Lifting axle: linear Z-axis for vertical movement
The lifting axis is a linear lifting system on the Z-axis. It raises and lowers loads in a controlled, fast manner with high repeatability. The ZeilhoferHub axle ZH90It can carry up to 1,200 kg on the linear Z-axis, making it the most powerful pendulum-free lifting axis in the portfolio.
Typical applications: High-voltage battery handling in final assembly, workpiece loading from above in CNC machining centers, large cast components in heavy industry, heavy loads in special construction.
The manipulator: flexible movement space in 3D
The manipulator moves loads in space. Swivel axes or an articulated arm provide a large working radius, up to 4.5 meters for the articulated manipulator. Depending on the design, loads move horizontally, vertically, and pivot around the vertical axis.
Typical applications: Final assembly in the automotive industry (doors, cockpits, seats), glass and panel handling, machine feeding with changing component variants, logistics and shipping with vacuum handling.
Lifting axis or manipulator: the decision criteria
Which system is suitable when depends on several criteria:
Load range: Lifting axle ZH90 up to 1,200 kg, manipulator up to 800 kg.
Main movement: vertical, lifting axis; in space with swiveling, manipulator.
Working radius: Compact lifting axis on the support system, manipulator up to 4.5 meters.
Component variation: both are flexible with quick-change grippers.
Cycle time: Hub axis often faster for pure Z-movements, manipulator for complex paths.
Investment: Lifting axis is usually more compact and cheaper; manipulator is more powerful for complex requirements.
Hybrid solutions: Lifting axis with flex arm
For applications that require both precise lifting and movement in space, there is the lifting axis.ZH90 Flex-ArmIt combines the linear Z-axis with an articulated arm, thus bridging the gap between a pure lifting axis and a pure manipulator. Ideal for cockpit installation, special fixtures, or applications with limited space.
Non-oscillating load guidance as a common standard
What all three systems have in common is pendulum-free load handling. The guided mechanism prevents uncontrolled oscillation and ensures precise positioning, even with loads in the ton range. Our guide to pendulum-free handling explains this in more detail.
Ergonomics and cost-effectiveness
Whether it's a lifting axis or a manipulator, both concepts reduce physical strain, minimize rejects of sensitive components, and increase throughput. Choosing the right option maximizes efficiency.

Frequently Asked Questions (FAQ)
What is the difference between a lifting axis and a manipulator?
The lifting axis operates on a linear Z-axis, raising and lowering loads in a controlled vertical direction. In contrast, the manipulator moves loads in space and offers greater flexibility with swivel axes or articulated arms. Both concepts operate without pendulum motion.
When is a lifting axle the right choice?
This is suitable when the main movement is vertical and heavy loads up to 1,200 kg need to be lifted precisely. Examples include high-voltage battery handling in automotive final assembly, top-loading of workpieces in CNC machines, and large cast components.
When is a manipulator the right choice?
For highly variable processes involving movement in space and a large working radius. Articulated manipulators achieve working radii of up to 4.5 meters, swivel around the vertical axis, and are ideal for final assembly, cockpit installation, or glass handling.
Lifting axis or manipulator: what loads do they both move?
The ZH90 lifting axis lifts up to 1,200 kg on the linear Z-axis, while articulated manipulators move up to 800 kg in space. Both systems operate without pendulum motion. We will determine which solution best suits your process during a process analysis.
