Tracked undercarriages – Solid and indestructible

A tracked undercarriage is the crucial foundation of many mobile machines. It bears the overall weight, ensures stability, and enables reliable movement on uneven or difficult terrain. This naturally includes the tracked running gear as the central element of the undercarriage. Depending on the application, various designs are used – from robust steel tracks to soil-friendly rubber tracks.

Our custom-made crawler undercarriages are used in a wide variety of machines, such as road construction equipment, crawler drilling rigs, milling machines, conveyor systems, underground mining equipment, and tracked mobile crushing plants. This results in solutions that are precisely tailored to the specific application – from traditional construction to specialized industrial plants.

Tracked undercarriages with steel tracks

Steel tracks are considered particularly durable and are primarily used in heavy construction machinery such as bulldozers or large crawler excavators. Within a crawler undercarriage, they consist of individual links connected by bolts, which reliably transfer the machine’s weight into the ground. Due to their high traction and durability, steel tracks are ideally suited for challenging soils, stony terrain, or extreme loads. The higher ground pressure is a deliberate compromise in favor of maximum stability.

Tracked undercarriages with rubber tracks

Rubber tracks are primarily used in more compact machines such as mini excavators, compact loaders, or agricultural equipment. As part of a crawler undercarriage, they offer significantly better ground protection, cause less vibration and leave no damage on paved surfaces such as asphalt or cobblestones. Rubber tracks run more quietly and provide greater comfort and flexibility – both for the operator and for the application.

Custom crawler undercarriages – tailored to your specific application

Crawler undercarriages must be adapted to the respective machine weights and the respective intended use in order to meet the different requirements. Lighter machines typically use smaller rubber tracks, while heavy construction vehicles and crawler excavators are equipped with massive steel tracks. Choosing the right weight class depends on various factors, including soil conditions, intended use and required load capacity.

We develop crawler undercarriages individually according to your technical requirements – from the track width to the base plates, rollers, clamping systems and drive assemblies. This results in an undercarriage that fits your machine and your daily use perfectly.

FAQ – Frequently Asked Questions

Can you also supply complete drive solutions?2025-11-21T15:41:31+01:00

Yes. We integrate suitable hydraulic or electric drive systems, including gearboxes and quality components from leading manufacturers, directly into the crawler undercarriage.

How long does it take to manufacture a custom-made crawler undercarriage?2025-11-21T15:40:26+01:00

The delivery time depends on the complexity, load range, and design requirements. Depending on the project scope, it typically ranges from several weeks to a few months. We will create a specific timeline after receiving your inquiry.

Do you also offer spare parts or components for existing crawler undercarriages?2025-11-21T15:37:19+01:00

Yes, we also supply individual components upon request, such as track rollers, support rollers, drive wheels, clamping systems, base plates, and steel or rubber tracks. Furthermore, we can technically overhaul or modernize existing undercarriages.

What information do you need to process an inquiry?2025-11-21T15:36:21+01:00

For precise design, we need data such as the machine classification, weight, desired travel speed, and operating conditions. Please use our inquiry form to provide us with detailed information about your requirements.

Can crawler undercarriages be individually customized?2025-11-21T15:30:54+01:00

Yes. Each undercarriage is fully customized based on the technical specifications of your machine. This includes frame construction, chain width, base plates, roller systems, drives and the entire load and service life calculation.

What are the advantages of rubber tracks?2025-11-21T15:29:27+01:00

Rubber tracks are gentle on the ground, produce low vibrations and are ideal for sensitive or paved surfaces. They are particularly suitable for mini excavators, compact machines, agricultural equipment or machines used in urban areas.

When are steel chains the right choice?2025-11-21T15:28:16+01:00

Steel chains are recommended for heavy machinery, high loads, and abrasive operating conditions. They offer maximum stability, wear resistance, and traction – for example, in earthmoving, quarrying, or underground mining.

Up to what machine weight do you design crawler undercarriages?2025-11-21T15:27:06+01:00

We manufacture crawler undercarriages for load ranges from 0.5 to 500 tonnes. We will review individual special solutions for additional requirements upon request.

For which machines are crawler undercarriages suitable?2025-11-21T15:24:07+01:00

Raupenunterwagen werden in einer Vielzahl von Maschinen und Anlagen eingesetzt, darunter Straßenbaumaschinen, Raupenbohrgeräte, Fräsen, Förderanlagen, Untertagemaschinen und raupenmobile Brechanlagen. Durch ihre robuste Konstruktion eignen sie sich für nahezu alle Anwendungen, bei denen hohe Stabilität und Geländegängigkeit erforderlich sind.

What is the difference between a crawler undercarriage and a crawler track?2025-11-21T15:22:18+01:00

A crawler undercarriage refers to the complete chassis system of a machine, consisting of frame, drive unit, tension and running rollers, and the actual crawler track. The crawler track is the part of the system that transfers power to the ground via steel or rubber tracks. It is therefore a central, but not the only, component of the undercarriage.
