Height-Adjustable Rear Axles
Toreq Earth Scrapers from Steiger feature forced straight front ejection for even, smooth spread of the spoils at the desired depth. All scrapers have the same hydraulically operated rear gate design for a straight, uniform push off of the spoils and elimination of dump-type unloading. A unique hourglass roller design remains parallel to the ground during loading operations for increased operator cutting control. The rear axles are height-adjustable, enabling the user to adjust and maintain a level position. One of the largest models, the 18000 shown here, has independent hydraulic circuits that control cutting depth, front-gate operation and soil ejection.
Number of models: 8.
Noteworthy features: Hourglass roller design, 360-degree swivel joint, wide gate opening, laser technology ready.
Forward Blade Design
The forward blade configuration of the Ashland I-180TS scraper is designed to evenly heap the material from front to back. Loading is easier, thanks to the combination of 126-inch width of cut and front lift control over the blade set. The push-off cylinders and 54-inch apron clearance makes getting rid of wet clay, stripped sod or muck quick and easy. A dual support system for the 3.5-inch pass-through axle clamped onto a solid steel pillow block system and two 29.5×25 E3-L3 28-ply earthmover tires help provide good flotation. The scraper has an 18-cubic-yard heaped capacity.
Number of models: 33.
New models: I-180TS, I-155XL2.
Noteworthy features: Durability, flotation, front load design, quick blade response.
Easily Changed Towed Attachments
Powered by Caterpillar modules and components, the Fox 673–4 elevating scraper includes a 102-hp Cat engine, a Cat four-speed forward and reverse transmission and a Cat differential lock. The 7-cubic-yard machine has an operating weight of 41,240 pounds. A quick hitch and quick-coupling hydraulics make it easy to change towed attachments such as a 2,000-gallon water tanker, a 7-yard dump and a 7-yard bottom dump as well as the scraper.
Number of models: 1.
Recent changes: New motor with less speed and more torque.
Noteworthy features: Bowl has fixed cutting edge, good view of edge, three axles, simple design.
Twin Engines Add Power
The 627G from Caterpillar is a 20-cubic-yard tandem-powered scraper, with the twin engines giving it the ability to handle steep grades and poor underfoot conditions. The machine can load independently or be push-loaded. The single-lever implement control combines the traditional three implement levers into one joystick. Machine status and real-time information is provided to the operator with Cat's electronic monitoring system. The fully integrated, electronically controlled power train offers improved power, enhanced shifting performance and specified diagnostics.
Number of models: 16.
Recent changes: Improved cab comfort.
Noteworthy features: G Series has electronically controlled engines and power trains, electro-hydraulic single-lever implement control.
Encased Hydraulic Hose
Scrapers from ICON include the D Series and the Contractors' Series. The Contractors' Series has a Swingwall eject system. Exposed hydraulic hose is encased in steel tubing and an integral side beam provides added strength. Heavy-duty 12-×12-×½-inch hitch beams have T-I encasement on the model 19C. A safety lighting system is standard as are rim-mounted mud bands that reject dirt and debris.
Number of models: 2.
Noteworthy features: Heavy-duty axles, high bit to ground clearance, bulkhead-mounted hose attachments with dual spring holder, remote routed grease points.
Standard Ripper Teeth
With a 17-cubic-yard capacity, the 417 scraper from Noble has a cutting edge width of 120 inches at a 30-degree angle with a maximum depth of 12 inches. Cutting and router bits are hardened and reversible for extended wear life. Ripper teeth come standard. A minimum of two hydraulic circuits is required to power the substantial hydraulic cylinders. Two bowl lift cylinders have a 5-inch bore by 18-inch stroke, with a single 5.5-×61-inch stroke cylinder powering the ejector. Two hydraulic cylinders actuate the apron. Two units can be transported on one 48-foot trailer.
Number of models: 1.
New models: 417 Pull Scraper.
Noteworthy features: Cellular structural design, 17-cubic-yard capacity, hardened steel ball and cap bearings at the draft frame and apron pivots, reversible cutting edges, ripper teeth and multiple hitch configurations.
Solidly Built Machine
Miskin emphasizes that its new D-18 scraper is a true construction-grade machine. The frame consists of solid, rigid steel between the hitch and the blade. The tractor's pulling force does not travel through any pivot points, hydraulic cylinders or pins. A larger heavy-duty hitch fits industry standard drawbars, with a 360-degree rotation that won't bind or break under tough conditions. The wheels pivot rearward, transferring more weight to the tractor for traction when loading.
Number of models: 27.
New models: D-18.
Recent changes: Improved durability and ease of maintenance, oil-filled hubs, larger tires, cushion ride, improved hitch, larger hydraulic lines and hydraulic components.
Noteworthy features: Unloads on grade, easy loading and faster unloading, new tires provide high flotation.
Electronic Engine Management
The S17E self-propelled, elevating scraper from Terex has an electronically managed engine for increased power and torque. The 285-hp engine teams with a powershift, counter-shaft type transmission that features eight speeds forward and one reverse. The top six forward gears have automatic lockup. Sequential "bump" shift results in smooth, low-effort changes. The cutting edge is in three sections, allowing either a straight or variable drop center. The two end sections are interchangeable.
Number of models: 2.
Recent changes: Power-down apron.
Noteworthy features: Electronically controlled transmissions, cushioned bowl suspension, panoramic operator's compartment, two-speed reversible elevator (S17E).
Individually Mounted Wheels
New to Rome's line, the 18CMX12.5 high-capacity contractors' scraper has an 18-cubic-yard capacity and efficient, self-loading bucket design. Standard features include a height-adjustable yoke hitch, tandem hydraulics and hitch, and extended Stinger center blade. Wheels are individually mounted and equipped with four 20.5R25 VUT (L2) radial tires. An innovative hydraulic system and heavy-duty 7-inch-diameter cylinders are designed for laser cuts and even spreading control. Options include a laser-receiver mounting bracket, drawbar assembly for the tractor, and even cut center blade. Tractor requirements are optimum 25 gpm @ 2,500 psi and 300 to 350 horsepower.
Number of models: 40.
New models: 18CMX.
