MANIPULATORS & LIFTING AIDS FOR AGRICULTURAL AND CONSTRUCTION MACHINERY
Ergonomically handle transmission, attachment and body parts up to 1,200 kg
Tractors, excavators, wheel loaders, and combine harvesters are made from heavy, often irregularly shaped components. ZHHT develops handling technology that adapts flexibly to changing components in agricultural and construction machinery, made in Germany, from a single source.
CHAPTER 1
Introduction
Tractors, excavators, wheel loaders, combine harvesters, and other harvesting machines are among the most complex machines in special-purpose machinery manufacturing. Municipal equipment, forestry equipment, and special-purpose vehicle construction present similar challenges. Their production demands handling technology capable of handling heavy, often irregularly shaped components, from gearbox housings and hydraulic cylinders to complete driver's cabs. Unlike in automotive mass production, the components to be handled in agricultural and construction machinery change frequently, and production volumes are smaller.
ZHHT develops manipulators and lifting aids that flexibly adapt to these changing requirements and relieve employees in tractor, excavator, and wheel loader manufacturing at every handling step. This guide shows which components are typically required, which ZHHT solution is suitable for which task, and how the process from inquiry to ready-to-use lifting aid works.
CHAPTER 2
Typical components and challenges
Four component groups most strongly determine handling requirements in agricultural and construction machinery manufacturing. Each places its own demands on load-bearing capacity, guidance, and gripping technology.
Transmission and drive components
Gearbox housings, axle drives, and hydraulic units are among the heaviest components in the assembly of agricultural and construction machinery. They often need to be rotated from a horizontal to a vertical position, precisely aligned, and fitted accurately. General principles of ergonomic gearbox assembly can be found in our guide , "Engine and Gearbox Assembly Handling ."
Attachments and tools
Loading buckets, plowshares, cultivator tines, mowers, and other attachments for tractors and construction machinery rarely have a standardized shape. To handle these irregularly shaped components, ZHHT develops custom gripping devices precisely tailored to their specific geometry. This allows even bulky or asymmetrically loaded attachments to be safely picked up, positioned, and mounted in agricultural machinery manufacturing without compromising the load's balance.
Driver cabins and body parts
Driver's cabs for tractors and construction machinery often weigh several hundred kilograms during cab assembly and must be precisely positioned on the frame. They guide the load vertically without any swaying and enable precise, smooth positioning, even in confined spaces in the production hall.
Wheels, tires and smaller attachments
Not every component in agricultural and construction machinery is heavy. Wheels, tires, tools, and smaller attachments can be moved flexibly and easily throughout the entire factory, independent of fixed compressed air connections. For precise, eccentric handling in confined spaces, a mobile, battery-powered solution without permanent installation is also ideal.

CHAPTER 4
Why standard solutions rarely fit
Agricultural and construction machinery manufacturers typically produce in smaller batch sizes than the automotive industry, but with a significantly greater variety of components: a single tractor model often exists in several cab, transmission, and attachment variants simultaneously. A lifting aid that can only accommodate a single component is hardly cost-effective under these conditions.
For this reason, ZHHT generally relies on individually designed gripping devices on standardized base systems for inquiries from the agricultural and construction machinery sectors, rather than simply offering off-the-shelf products. The base system (manipulator, lifting axis, hoist, or cable manipulator) remains proven and easy to maintain, while the device at the load-bearing point is precisely tailored to the specific component geometry. This ensures that the investment remains economical even with model changes and a wide variety of variants.

FAQ / Q&A
FREQUENTLY ASKED QUESTIONS
01 Was ist der Hauptunterschied zwischen Manipulator und Cobot?
Ein klassischer Manipulator wird manuell vom Bediener geführt und übernimmt nur das Gewicht der Last. Ein Cobot arbeitet programmiert und vollautomatisch, darf aber wie die ZH90 ohne Schutzzaun neben Mitarbeitern eingesetzt werden.
02 Kann die Hubachse ZH90 wie ein Cobot eingesetzt werden?
Ja. Die ZH90 ist als manuelle und/oder kollaborierende Hubachse konzipiert. Kraft- und Momentensensoren erkennen kritische Belastungen und stoppen automatisch bei Kollision, ein Betrieb ohne klassische Schutzzäune ist möglich.
03 Wie viel Last kann die ZH90 im kollaborativen Modus bewegen?
Im kollaborativen Modus bewegt die ZH90 Lasten bis 300 kg. Im klassischen, manuellen Modus ohne Kollaborationseinschränkung sind es bis zu 1.200 kg.
04 Kann die ZH90 auch lange Strecken zurücklegen wie ein mobiler Cobot?
Ja, über ein Fahrschienensystem verfährt die ZH90 auch über längere Strecken, statt nur stationär an einem Arbeitsplatz zu arbeiten.
05 Ist ein Cobot immer die modernere und bessere Lösung?
Nicht zwangsläufig. Bei mehrachsigen, komplexen Bewegungspfaden ist ein klassischer Cobot-Arm im Vorteil. Für lineares Heben, Positionieren und Verfahren bis 300 kg deckt die ZH90 kollaborativ denselben Anwendungsfall oft direkt ab.
06 Bietet ZHHT auch einen frei programmierbaren 6-Achs-Cobot-Arm an?
Nein, ZHHT bietet keinen eigenständigen 6-Achs-Cobot-Arm an. Für lineares kollaboratives Heben und Verfahren deckt die Hubachse ZH90 viele typische Cobot-Anwendungsfälle bereits selbst ab.
07 Wie aufwendig ist die Programmierung der ZH90 im kollaborativen Modus?
Dank Teach-in-Funktionalität ist die Programmierung auch ohne tiefgehende Programmierkenntnisse möglich, die Integration in bestehende Systeme erfolgt schnell und effizient.
08 Kann man Manipulator, Cobot und ZH90 kollaborativ in einem Prozess kombinieren?
Ja. Häufig übernimmt ein mehrachsiger Cobot komplexe Bewegungspfade, die ZH90 kollaborativ das lineare Verfahren, und ein klassischer Manipulator besonders schwere oder variantenreiche Bauteile bis 1.200 kg.
09 Ist auch für den kollaborativen Betrieb ohne Schutzzaun eine Risikobeurteilung nötig?
Ja. Auch kollaborierende Systeme wie die ZH90 benötigen eine dokumentierte Risikobeurteilung nach ISO/TS 15066, unabhängig davon, ob ein Schutzzaun eingesetzt wird oder nicht. ZHHT unterstützt bei der Einordnung im Rahmen der Prozessanalyse.
10 In welchen Branchen kommen Manipulator, Cobot oder die ZH90 kollaborativ typischerweise zum Einsatz?
Alle drei Lösungen finden sich in Automotive, Maschinenbau, Elektronikfertigung und Logistik. Welche Technologie passt, hängt weniger von der Branche als vom konkreten Bauteil, der Losgröße und der Taktzeit ab.
11 Wie unterscheiden sich die Kosten von Manipulator, Cobot und ZH90 kollaborativ?
Ein klassischer Manipulator ist meist am günstigsten, da keine Programmierung nötig ist. Ein frei programmierbarer Cobot-Arm erfordert zusätzliche Investition in Integration und Programmierung. Die ZH90 kollaborativ liegt dazwischen: Grundsystem plus Vorrichtung, ohne separate Roboterprogrammierung.
12 Was passiert, wenn der kollaborative Modus der ZH90 ausfällt?
Fällt der kollaborative Modus aus, lässt sich die ZH90 jederzeit manuell weiterbedienen. Der Prozess muss nicht unterbrochen werden.
13 Kann die ZH90 eigenständig arbeiten, während der Mitarbeiter andere Aufgaben erledigt?
Ja. Die ZH90 kann zum Beispiel selbstständig ein Bauteil aus einem weiter entfernten Behälter holen, während der Mitarbeiter parallel einen anderen Arbeitsschritt ausführt. Anschließend verbaut entweder die ZH90 automatisch weiter, oder der Mitarbeiter übernimmt die Führung manuell.
