![]() It incorporates design elements of both a CTL and those of both small and large dozers. It’s available with both rubber and steel tracks and Case calls it a “dozer-style” undercarriage. Three key elements to true dozing performanceĭesign, capacity and performance aside, Case tells us that the three key elements of the DL550B that make this a true two-in-one machine are its dozer-inspired undercarriage, the chassis integrated, pin-on C-frame that holds the 6-way dozer blade, and its control scheme. That change is what enabled a jump from 4,500 pounds of capacity to 5,500 pounds, while also increasing dozing performance and allowing the machine to reach deeper into trucks. So it’s a closed loop system that provides more efficiency and really what that’s for is that’s giving you that high tractive effort that you are expecting from a dozing application to make sure you’ve got good push forces.”Īnother key change in the development of the production model in the time since the concept debuted three years ago, is that Case switched from a radial-lift design to a vertical-lift design. ![]() “…We do still run a hydrostatic but this is a pressure-compensated, load-sensing system. “This machine is basically a step up above what we currently have on our other (CTL) models,” says Brady Lewis, Project Minotaur program manager at Case. The DL550B also has a more powerful engine at 114 hp, compared to the TV450B’s 90 hp. While the TV450B has a rated operating capacity of 4,500 pounds, the DL550B has a capacity of 5,500 pounds. This time around Case didn’t just take a large CTL like the TV450B and throw a dozer blade on it and send it out the door. The production machine unveiled at ConExpo 2020, however, is a very different beast. That prototype concept created a huge amount of buzz at ConExpo 2017. It was created by taking the base frame of a vertical-lift TV380 CTL that was then married with a radial-lift loader arm design similar to that of the former Case 465 skid steer. The model name for that original Minotaur prototype was the DL450 a nod to Case’s former 450 dozer. Or in the case of Case’s monster, part compact track loader, part bull dozer. At that show, Case introduced a prototype it was affectionately calling Project Minotaur, a reference to the monster from Greek mythology that was part man, part bull. The DL550B traces its origins back to ConExpo 2017. From the undercarriage to a chassis-integrated C-frame, to full machine control support, it was designed to be a true two-in-one machine, capable of both heavy dozing and loading tasks.Ĭheck out our full coverage in the video below along with footage of the DL550B in action. The DL550B isn’t just a compact track loader equipped with a dozer blade. ![]() An operator figure is included in the detailed cabin, and the dozer is painted Caterpillar's familiar yellow cover.At ConExpo 2020 Case followed its unveiling of a fully-electric backhoe with the introduction of the DL550B, a machine that represents an entirely new machine category-the compact dozer loader-and one that has been several years in the making under the code name Project Minotaur. The tracks are made of metal, and of course they move a three-claw ripper is mounted to the rear of the dozer. This completed die-cast display model of the CAT D3 dozer comes in a decorative metal can case printed with photos of the actual vehicle, making it an ideal display piece for your collection! The engine compartment hatch can be opened to admire the engine inside and closed again the accurately shaped dozer blade moves up and down. Fitting its status as a next-generation bulldozer, the driver's seat is equipped with a touch-screen monitor to improve operability. The D3 demonstrates excellent work efficiency. Its engine is a 3.6-liter in-line four-cylinder diesel with a turbocharger it's equipped with an advanced electronically controlled transmission which senses operations and workloads, and controls the fine-tuned hydraulic pump and motor. One of Caterpillar's most well-known bulldozers is the CAT D3 dozer. This is a die-cast metal and plastic display of construction equipment.
