THE 2811E Under 12ft. Road Transport
The 2811E is one of the four new ejector scrapers introduced this year. This scraper bowl width and height is the same as the 2411E. The bowl’s length is simply 12″ longer, increasing the heaped capacity to a productive 28 cu.yds. The 2811E is the only high capacity scraper that is under 12ft. road transport reducing your mobilization cost from costly escorts or permits.
HITCH SYSTEM:
The direct mount scraper 360-degree swivel hitch is closely coupled to the specialized tractor drawbar, which provides better weight distribution between the tractor front and rear axles.
FRONT HYDRAULIC PUMPING:
The weight of 3/4″ front hydraulic connecting hoses is supported by a spring-loaded hose carrier, providing an ideal coupler connection between the tractor and the scraper. This reduces premature coupler wear and accidental coupler “pop-out” from hose weight or binding while operating.
A thick rubber pad keeps the couples off the ground when the scraper is not in use.
FRONT SECTION:
The backbone of the front section begins the heavy wall 16″ pipe. This robust front section pipe reduces the high stresses experienced while loading, transporting, and lifting fully loaded scrapers. Large cast steel flanges are applied to the middle of the front section pipe provide commonality of parts between multiple models. This offers more flexibility and increased efficiencies at the factory; more importantly, it gives the end-user excellent value for the dollar.
EASY UNLOADING:
The combination of 2811E spacious 74.25″ front opening and the 25.62″ ground clearance, the material can exit the scraper unobstructed, which reduces double ejecting thicker material. Allowing the operator to place material exactly where it is needed, which increases your daily production.
EASY LOADING:
We lowered the connecting point of the front section trailing arms to the scraper bowl down near the blade to provide easier pull while reducing the duck-walking while loading. Allowing the operator to maintain a higher loading speed, more constant tractor RPM, which translates to larger payloads.
HYDRAULIC SYSTEM:
The 2811E requires three hydraulic remotes to operate the machine. One circuit controls the lift cylinders. The second circuit controls the apron and the third circuit operated the ejector system. This allows the operator full control of all the functions independently.
WHEEL SYSTEM:
The multiple holes within the rear frame enable the operator to position rear axles in numerous positions. Select to place all the tires to be “in-line” for increased compaction or “offset” for better floatation and less mud build-up. So, regardless of your soil condition, there is a tire package available to keep you floating on the soil and moving forward.
QUICK DAILY SERVICE:
Daily maintenance is short work, whereas there is only six daily grease points located on the front hitch. The ejector wall is guided with large plastic blocks, and all the pivot joints, cylinder pins, and floor rollers utilize oversized pins with self-lubricating bushings.
