Tyre excavator

Industrial components for the manufacture of wheeled excavators

Wheeled excavators, also known as wheeled diggers, are subjected to extreme stresses on a daily basis on construction sites, in roadworks or during municipal works. Their operation is often accompanied by high noise levels, strong vibrations and significant temperature fluctuations – affecting both the machinery and the operators in the cab. Targeted sound and thermal insulation, as well as well-designed vibration decoupling, are crucial for enhancing comfort and safety.

We are happy to assist you in selecting suitable materials and offer tailor-made solutions – tailored to your requirements and spatial conditions.

Noise reduction through targeted sound insulation

The engine, hydraulic units and the vehicle’s operation itself generate a significant level of background noise – particularly in the cab area. To effectively minimise this airborne and structure-borne noise, high-performance heavy-duty films (Terodem® and Teroform®) made from bitumen or EVA are used. These are applied directly to metal surfaces – such as engine cowlings, the cab floor or wheel arches – and suppress disruptive vibrations in the sheet metal.

These are combined with acoustic foams, such as recycled PUR foam or melamine resin-based foams (Basotect® G+), which absorb sound while meeting fire safety standards. The materials can be flexibly deployed throughout the interior – for example, behind wall panelling, in the cabin roof, under seats or in the area of engine compartment covers.

Thermal insulation for improved climate control

In pneumatic excavators, engine heat and sunlight often cause high temperatures in the cab. At the same time, it can cool down quickly in cooler weather. Targeted thermal insulation ensures a more stable indoor climate and reduces the load on the heating and air conditioning systems.

Closed-cell PE foams (Plastazote MP15FR) or synthetic rubbers such as Armaflex®, Vibra®Flex or K-Flex are used here. These are moisture-resistant, durable and easy to work with – ideal for wall structures, ceiling areas and technical enclosures. Aluminium laminates also help to reduce heat radiation, particularly in the cabin roof or in direct sunlight.

Vibration control – less vibration, greater durability

A key issue with pneumatic excavators is the reduction of vibrations transmitted directly into the cab or the vehicle structure from the undercarriage, the engine or operational processes. In the long term, these vibrations can lead to material fatigue, increased wear and physical strain on the operators.

Special elastomers such as Sylomer®, Sylodyn® or rubber-metal elements are used for effective vibration decoupling. These are used, for example, under machine foundations, between cab mountings or in the area of the driver’s platform.
