ONE PARTNER FOR EVERY COMPONENT OF YOUR VEHICLE PRODUCTION
From delicate visible parts to 1,200-kilogram high-voltage batteries: Zeilhofer handles the entire spectrum of automotive components from a single source. Ergonomic, process-reliable, and custom-designed to your specific geometry.
CHAPTER 1
In vehicle assembly, every component presents a handling problem.
A windshield must not be scratched. A high-voltage battery weighs several hundred kilograms and must be inserted into the vehicle floor with millimeter precision. A front end is bulky and tilts when lifted. A cordless screwdriver puts strain on employees due to its own weight and reaction torque. Each of these parts has a different physical property to consider, and Zeilhofer has the right solution for each of these properties.
This is precisely the difference compared to specialized suppliers who only cover one segment, such as vacuum technology or lightweight construction. Zeilhofer supports the entire vehicle assembly process across the entire load range and designs every gripper and fixture as a custom-built solution tailored to the specific component geometry.
This guide does not arrange automotive components alphabetically, but rather according to their actual handling challenges. For each group, it specifies the realistic load class, explains the underlying technical principle, and provides concrete application examples drawn from over two decades of special-purpose machine construction.
The right solution for each load class
-
Lifting axle ZH90 = 1,200 kg
-
Manipulator = 800 kg
-
Flex-Arm = 200 kg
-
Rope manipulator = 150 kg
-
Lifting lift ZH = 100 kg
CHAPTER 2
Sensitive visible parts
Paint, glass, and visible surfaces cannot tolerate scratches or pressure marks. Here, the decisive factor is not the load-bearing capacity, but the type of grip. Form-fitting, component-specific grips with soft contact surfaces replace point-based suction technology, which reaches its limits with structured or curved visible parts.
Equally important is the vibration-free guidance: When installing a windshield, tight tolerances are crucial; a swinging component would touch the body. The balancer technology keeps the load steady and weightless in every position.

CHAPTER 3
Heavy load up to 1,200 kg
High point loads, precisely guided: Depending on the vehicle model, a high-voltage battery weighs around 300 to 700 kg, with larger versions weighing even more. Axles, transmissions, and complete drive units are in a similar range. This is precisely where the advantage of the ZH90 lifting axle, with a load capacity of up to 1,200 kg, lies: It guides heavy, compact components safely and with millimeter precision to their installation location.
If a particularly large battery exceeds the load-bearing limit, it is handled module- or cell-block-wise. The appropriate mounting is always custom-built.

CHAPTER 4
Bulky add-on parts
Bulky components with a shifting center of gravity tend to tip over when lifted. Exhaust systems, front ends, bumpers, and trailer hitches therefore require less pure lifting power and more precise center of gravity control and a fixture that holds the component stably in position. Manipulators and cable manipulators guide such loads in a balanced and rotatable manner.
The direction of assembly also plays a role: springs and dampers are joined under defined preload, and the device must be able to safely absorb these forces.

CHAPTER 5
Screwing and assembly technology
Not only components, but also the tools themselves need to be relieved of stress. An industrial screwdriver transmits a reaction torque to the operator when tightening, which leads to considerable strain over a workday. The ZH90 lifting axis supports screwdrivers and cockpit modules, bears their weight, and absorbs the reaction torque, while the operator only needs to guide the tool.
The effect is twofold: reduced physical strain and a repeatable, consistent screw-fastening quality in series assembly.

CHAPTER 6
E-mobility: the most demanding handling in assembly
No area of vehicle production is changing handling procedures as drastically as electromobility. The high-voltage battery is the heaviest single component in the vehicle and is lifted into the floor of the vehicle from below, under tight tolerances and in a timed production line. Weight, precision, and workplace safety all converge here.
Zeilhofer has been involved in this transformation for years: from the ergonomic handling of individual battery modules to the gripper for the battery housing, all the way to the complete high-voltage battery on the ZH90 lifting axis. Because each battery platform has a different geometry, the mounting is always custom-built, secured by TISAX Level 2 certified handling of prototypes.

CHAPTER 7
Why handling technology is increasingly becoming a necessity rather than an option
Musculoskeletal disorders are among the most frequent causes of sick days in production. Every lost workday costs money, and in mass production, this quickly adds up. Ergonomic handling technology is therefore not only a matter of occupational safety, but also a matter of business management.
In addition, there is the legal framework. In Germany, the Manual Handling Ordinance regulates the manual handling of loads, assessed using the key indicator method. From 2027, the EU Machinery Directive will further tighten the ergonomic requirements for machines and equipment. Those who invest in handling technology today will meet these requirements and future-proof their production.

CHAPTER 8
Four steps to the right solution for your component
The most suitable handling solution is determined by four questions. These also form the basis of every design consultation with our engineers.
01 WEIGHT
How heavy is the component? This determines the product line, from 100 kg lifting platform to 1,200 kg lifting axle ZH90.
03 Surface
Visible part or robust? Sensitive surfaces require form-fitting, scratch-free grippers instead of point-contact gripping.
02 Focus
Compact or bulky? Large parts with a shifting center of gravity require balanced center of gravity guidance.
04 cycle time
How often per shift? The frequency of movement determines ergonomics, degree of automation, and operating concept.

FAQ / Q&A
FREQUENTLY ASKED QUESTIONS
01 Which components can be moved using handling technology?
Virtually every heavy or bulky component: high-voltage batteries and battery housings, vehicle axles and e-axles, transmissions, doors, front and rear hatches, windshields and glass roofs, seats and cockpit modules, tires and wheels, exhaust systems, bumpers, trailer hitches, as well as springs and dampers. A different characteristic is crucial for each component: weight, center of gravity, surface sensitivity, or cycle time.
02 Up to what weight can a component be handled?
The ZH90 lifting axis handles loads up to 1,200 kg, such as high-voltage batteries, axles, or gearboxes. Manipulators cover loads up to 800 kg, the flex arm up to 200 kg, the cable manipulator up to 150 kg, and the lifting platform up to 100 kg. Large high-voltage batteries of some models can exceed the 1,200 kg limit and are then handled module by module or cell block by cell block.
03 How are sensitive visible parts handled without damage?
Component-specific grippers and fixtures ensure a scratch- and mark-free grip and guide the load without swinging. The crucial factor is not the load capacity, but rather defined gripping points, soft supports, and a balanced movement that prevents impact or tilting. This allows for the secure installation of windshields, glass roofs, and painted front and rear hatches.
04 How is a high-voltage battery safely installed in the vehicle floor?
The high-voltage battery is the heaviest single component in the electric vehicle and is lifted into the vehicle floor from below, under tight tolerances and in a timed production line. The ZH90 lifting axis guides the battery, weighing up to 1,200 kg, to its installation location with millimeter precision, without any pendulum movement and with a defined mounting. Because each battery platform has a different geometry, the mounting is custom-made.
05 Is handling technology also suitable for screw and assembly technology?
Yes. The ZH90 lifting axis accommodates screwdrivers and fastening technology and positions them ergonomically and with repeatable accuracy at the joining point. This relieves employees of the weight and reaction torque of the tool and ensures consistent fastening quality in series assembly.
06 What does a handling solution for automotive production cost?
The price depends on component weight, gripper geometry, working area, and degree of automation, as each solution is custom-built. Economically, the amortization is more crucial than the purchase price: A handling solution reduces absenteeism due to musculoskeletal disorders, accelerates cycle times, and minimizes component damage. In many cases, it pays for itself within just a few years.
07 How does the development of a component-specific device proceed?
The process begins with the component geometry, including weight, center of gravity, and gripping points. From this, our engineers design, construct, manufacture, and commission grippers and fixtures – all under one roof. Handling prototypes is secured through TISAX Level 2 testing, which is particularly important in the early development phase with automotive manufacturers.
08 What legal requirements apply to manual handling of loads in production?
In Germany, the Manual Handling Ordinance regulates the manual handling of loads, assessed using the key indicator method. From 2027, the EU Machinery Directive will tighten the ergonomic requirements for machinery and equipment. Handling technology demonstrably reduces physical strain and helps to meet these requirements.
