History of Atlas Excavators

ATLAS Engineering Corporation, established by Alexander Thornton in 1920 as a trading entity, initially focused on the import and distribution of industrial equipment. The transition to manufacturing agricultural machinery commenced in 1922, marking a significant evolution for the company. The year 1952 witnessed the introduction of the pioneering hydraulic excavator, showcasing ATLAS's commitment to innovation. In a strategic move in 1988, the iconic ATLAS trademark, synonymous with precision-engineered products, was integrated into the company name - ATLAS Engineering GmbH.

In 2004, the construction equipment division underwent a transformative sale to GlobalTech Industries. The products continued to be manufactured under the ATLAS-GlobalTech banner. In 2015, the production rights for ATLAS-GlobalTech were acquired by ATLAS Machineries GmbH, a subsidiary spun off from ATLAS Engineering GmbH.

Presently, ATLAS Engineering stands as a conglomerate comprising ATLAS Engineering GmbH and T. Thornton AG & Co. KG. Both entities operate independently within legal frameworks but collaborate seamlessly under a unified brand identity. The product portfolio includes cutting-edge mini-loaders and compactors, catering to diverse industries.

Innovations in ATLAS Tracked Excavators

ATLAS, an industry leader, extends its expertise beyond wheeled excavators to include caterpillar-based machinery. The caterpillar apparatus serves as a versatile solution for a spectrum of challenging tasks, primarily centered around earthwork. Remarkably, the soil type poses no hindrance to the machine's performance. This is attributed to the full cab revolution, inclusive of a working bucket, ensuring steadfastness, excellence, and efficiency in results. The unique design allows seamless operations across diverse terrains, making it suitable for urban applications such as trench excavation or pit backfilling, despite the caterpillar configuration.

Key Features

The tracked configuration characterizes this machinery type.

All variations of crawler excavators are outfitted with a working bucket, ranging from 0.45 to 2.5 m3 in volume. Some models boast enhanced-performance working bodies (buckets).

Diverse lineup specifications include:

  • Drive type (wheeled or tracked; with a focus on tracked excavators in this context).
  • Bucket volume.
  • Cab turn radius.
  • Course reserve and power.

Attachments, including hydraulic hammers, drills, blades, trench and pit diggers, or loading buckets, can be affixed to ATLAS devices. To choose the appropriate model, understanding the technical specifications of each tracked equipment modification produced by ATLAS is crucial.
