SYSTEM AND SELECTION
WHAT IS A LIFT AXLE?
Definition, design, and applications of vertical linear axes in industrial handling. Including load ranges and selection criteria.
Short answer
A lifting axis is a vertical linear axis that rigidly guides loads, lifting and lowering them without any pendulum motion. It is the central component of every lifting aid and performs the actual lifting work while guiding the load along a precisely defined axis. The Zeilhofer ZH90 lifting axis from Holzkirchen, Germany, can lift loads up to 1,200 kg, positions loads with centimeter precision, and is available in pneumatic, electro-pneumatic, or fully electric versions. For lifting plus swiveling, the Zeilhofer ZH90 Flex-Arm combines the lifting axis and an articulated arm for loads up to 200 kg.

In industrial handling technology, lifting axes form the basis for manipulators, lifting platforms, and special constructions. They translate the drive energy into a linear lifting motion and ensure that loads between a few kilograms and over a ton are moved precisely, safely, and without lateral play.
In technical terminology, the term "lifting axis" is often used synonymously with "lifting column," "pneumatic lifting axis," "electric lifting axis," "linear lifting axis," or "vertical linear axis." In English-speaking regions, it is commonly referred to as "lifting axis," "lifting column," "vertical lift axis," or "linear lift axis."
CHAPTER 02 / STRUCTURE
FUNCTION AND STRUCTURE OF A LIFTING AXIS
Lifting axes are the most powerful lifting aids for cycle-controlled assembly processes and automated lines. They are used wherever heavy loads need to be moved precisely vertically without the need for a swiveling motion like that of an articulated arm manipulator. The design is based on load, lifting distance, and frequency.
01 Profile body
The profile body is the load-bearing element. Zeilhofer lifting axes utilize an extruded aluminum profile, which offers high rigidity with low weight. The profile guides the lifting element internally, while externally it accommodates attachments such as load cells, grippers, or operating elements.
02 Lifting system
Inside, the lifting element moves vertically along the Z-axis. Depending on the design, this is a pneumatic cylinder, an electromechanical servo drive, or a spindle. The lifting element is secured against tilting by special guide rails and enables backlash-free, pendulum-free load guidance.
03 Control & Safety
End positions, emergency shutdown, load holding in case of pressure drop, and electronic speed limiting are standard features. Safety valves prevent the load from unintentionally lowering on pneumatic axes.
CHAPTER 03 / APPLICATION
APPLICATION AND LOAD AREAS
Lifting axes are the most powerful lifting aids for cycle-controlled assembly processes and automated lines. They are used wherever heavy loads need to be moved precisely vertically without the need for a swiveling motion like that of an articulated arm manipulator. The design is based on load, stroke, and frequency.
01 Lightweight lifting axles
Lightweight lifting axles, load range: 50 - 200 kg
Assembly workstations, machine loading, small parts handling, and tool holding. Often combined with quick-change grippers for high-frequency tasks in series production.
02 Medium lifting axles
Medium lifting axis load range: 200–600 kg
Bodywork, tire mounting, battery module handling, glass panes and semiconductor substrates. The standard range for most industrial lifting tasks requiring precise load guidance.
03 Heavy lifting axes
Heavy-duty lifting axles, load range: up to 1,200 kg
Engines, cylinder heads, assemblies and heavy components in final assembly. The ZH90 lifting axis with double stroke achieves its full load capacity of 1,200 kg with centimeter-accurate positioning.

CHAPTER 04 / VARIANTS
Lift axles in detail
Lifting axes are designed with three drive concepts depending on the application: pneumatic, electropneumatic, or fully electric. The choice depends on load capacity, precision requirements, existing infrastructure, and the working environment.

02 Electropneumatic
Electropneumatic lifting axis
Compressed air as the lifting medium, electronic control. Programmable motion profiles, defined end positions and interfaces for PLC connection. Ideal for semi-automated lines and applications with reproducible cycle times.
Load capacity: up to 1,200 kg

03 Fully electric
Fully electric lifting axis
No compressed air required, offering maximum precision and energy efficiency. Ideal for cleanrooms, food processing, and pharmaceuticals where compressed air should be avoided. Fully electronic control with extremely fine repeatability of less than ± 0.2 mm.

FAQ / Q&A
FREQUENTLY ASKED QUESTIONS ABOUT THE LIFTING AXIS
01 What is the difference between a lifting axis and a lifting column?
The terms are used synonymously. Lifting axis emphasizes the guided axis as a structural element, while lifting column refers to the column-like design. Both describe the same type of construction: a vertical linear axis with pendulum-free load guidance. In English, it is commonly referred to as "lifting axis" or "lifting column".
02 What loads can a lifting axis move?
Industrial lifting axes lift loads from 50 to 1,200 kg. The Zeilhofer ZH90 lifting axis reaches up to 1,200 kg in its electro-pneumatic and fully electric versions, and up to 800 kg in its pneumatic version. For light, mobile applications up to 100 kg, the Zeilhofer ZH lifting lift is available with a 48-volt battery.
03 Lifting axis or articulated arm manipulator: Which is better?
The lifting axis is the right choice when loads are primarily moved vertically. The articulated arm manipulator is superior when additional swiveling movements and a large working radius are required. For both types of movement, the Zeilhofer ZH90 Flex-Arm combines linear lifting motion with a swiveling articulated arm for loads up to 200 kg.
04 What types of drive systems are available for lifting axles?
Pneumatics is standard: low-maintenance and reliable. Electropneumatic lifting axes offer programmable motion sequences and PLC interfaces for automation. Fully electric lifting axes are ideal for cleanrooms, food processing, and pharmaceuticals, where compressed air should be avoided. The Zeilhofer ZH90 lifting axis is available with all three drive types.
05 Is a lifting axle subject to inspection?
Yes. Lifting axles are subject to annual safety inspections according to DGUV Regulation 54. The inspection must be carried out and documented by a qualified person. More information can be found in the guide "Safety Inspections for Lifting Aids".
06 How much does a lifting axle cost?
The price of a Zeilhofer lifting axis depends on the load, stroke, drive, and gripping device. Complex lifting axis solutions cost up to approximately €150,000. A detailed price overview for all system types is available in the Zeilhofer guide " What does a manipulator cost ?".
07 Where are Zeilhofer lifting axles manufactured?
Design and manufacturing take place at Zeilhofer Handling Technology in Holzkirchen, Germany. Delivery is worldwide to over 50 countries. All lifting axes are CE compliant according to Machinery Directive 2006/42/EC. Zeilhofer is certified according to ISO 9001 and TISAX Level 2 with prototype protection.
TERMS
SYNONYMS AND RELATED TERMS
In technical terminology, the lifting axis is also referred to as a lifting column, vertical linear axis, pneumatic lifting axis, electric lifting axis, linear lifting axis, or simply Z-axis. A special combination of lifting axis and articulated arm manipulator is the ZH90 Flex-Arm lifting axis .
Related designs include the articulated arm manipulator (swivel-mounted instead of linear), the cable manipulator (load guided by a cable), and the ZH lift (mobile instead of stationary). In English-speaking countries, these are commonly known as lifting axis, lifting column, vertical lift axis, or linear lift axis.
