Inside the Liebherr Bulldozer Factory | FULL Production Process

Video Description

Liebherr Production Crawler Dozers in Austria | How GIANT Bulldozers Are Built The full inside look at Europe’s most advanced crawler dozer manufacturing factory — Liebherr-Werk Telfs in Austria. In this documentary, you’ll see how the famous PR 716, PR 736, PR 756 and the flagship PR 776 bulldozers are built from raw steel to fully tested, ready-to-ship machines. Filmed inside the real production lines of Liebherr Telfs, this video shows: 🏭 1. Cutting, Machining & Steel Preparation • Laser and oxy-fuel cutting of heavy steel plates • CNC milling, drilling and grinding • Precision shaping of parts used in crawler frames and blades 🔥 2. Welding & Fabrication • Frame welding for PR-Series bulldozers • Blade fabrication and massive structural welds • Manual and robotic welding stations ⚙️ 3. Assembly Line – The Bulldozer Takes Shape • Track frames assembling • Cab mounting and hydraulic line routing • Engine installation • Cooling modules and heavy components The heavy steel frames move through the shop on large platforms, transforming into fully functional crawler bulldozers. 🦾 4. Track Installation — The Most Impressive Part Watch technicians install the enormous steel tracks on the Liebherr PR 776, using cranes, rollers and precise coordination. This is one of the most complex and powerful visual stages of the entire production. 5. Testing & Calibration • First engine start • Steering and hydraulic checks 🚛 6. Shipping — Ready for the World • Bulldozers are driven onto heavy-duty trailers • Secured with chains and rigging systems • Shipped to customers around the globe Liebherr’s Telfs factory is one of the most advanced crawler dozer plants in the world, combining precision engineering, high-level craftsmanship and unmatched attention to quality.
