Construction machinery

In order to complete construction projects in as little time as possible, machines such as soil drilling devices, skips, concrete pump cantilevers, vibrating rollers, wheel bearings and pivot bearings are indispensable.

rothe erde® slewing bearings are developed to withstand hard operating conditions around the world. In close collaboration with customers, our engineers develop economic solutions, which are perfectly tailored to individual demands.

Our solutions in the field of construction machinery

Drilling devices and attachments

A basic device with different attachments: Here, Rothe Erde provides the optimal solution. Our experiences gained from the field of stand-alone devices are indispensable when it comes to attachments’ application scenarios and their specific operational conditions. Rothe Erde slewing rings are designed to dependably meet expectations in terms of ease of service, reliability and durability.

Skips

Skips, also called dumpers, are often used on construction sites for the removal of excavation and construction materials, since the tilting device enables fast and precise emptying. Rothe Erde delivers bearings for the built-in slewing ring, which allow for durable and uninterrupted operation.

Concrete pump cantilevers

Concrete is the most commonly used construction material. A concrete pump is used to transport the mass of concrete quickly and efficiently to areas which are difficult to access. A pivot arm which aligns the concrete pump's nozzle with the desired location is required for this. A slewing ring makes sure that the pivot arm can be perfectly controlled. When developing and constructing slewing rings, Rothe Erde pays close attention to ensuring the latter’s precision and robustness meet the demands of construction sites around the world. High tilting moments when extending the concrete pump cantilever are reliably transmitted to ensure the pump operates safely.

Vibrating rollers

Vibration rollers compress soil and asphalt. A slewing ring in the break joint makes this type of roller very flexible. The front roller can be precisely controlled. This allows the vibration roller to reach the ground which needs to be compressed without the need for manoeuvring. This results in great time savings by reducing operational time at the construction site and by making the ground areas worked on more quickly accessible again. Our engineers have developed a product that withstands the hard operational conditions and strain caused by dust, dirt and heat that remains economical for roller manufacturers and guarantees reliability and ease of service for users.

Wheel and swing loaders

Wheel and swing loaders are amongst the most versatile machines used for the transporting and removal of goods on a construction site. Since the attachments can be changed, there is a large range of operational areas. Rothe Erde slewing rings in the break joint make it possible for these construction machines to move fast and flexibly around a small space. Of course, we also ensure the slewing rings are as robust and durable as possible.
