![]() ![]() (At one point in our video above, you can actually see the connection locking in.) Case tells us this design was the difference maker in delivering true six-way blade performance and long-term precision. The C-frame attaches directly into the chassis and primary coupler of the DL550B in a matter of seconds. And the key to that pivot is the DL550B’s c-frame and six-way blade. A machine that performs serious dozing tasks and then quickly pivots to heavy CTL loading tasks, however, is quite novel. ![]() Not to belabor the point, but putting a dozer blade on a CTL is not a novel concept. “That gives you a true alignment across your undercarriage and that is key to long life when it comes to steel rolling components.” “…Also the mounting scheme for this undercarriage, there is a solid steel cross shaft that runs across the length of the vehicle and that is the same mounting scheme that we use on our 1650M or 2050M dozer. “The rolling components-the rollers, the chains, the grousers-those are literally the same components that we use on our much bigger Case 650M dozer,” Lewis says. ![]() 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. ![]()
