New Titan Scraper System Combines Power, Strength, Speed With Longer Life

Titan Earthmoving Equipment (Titan EMD), a division of Titan Trailers, has introduced a new high-capacity scraper system that integrates a 44 cu. yd. (33.6 cu m) bowl with a Bell 4206D scraper tractor.

“This is the first earthmoving system designed specifically to build on the power and efficiency of today’s most advanced scraper tractors,” said Mike Kloepfer, president of Titan EMD. “By engineering the two units to work together, the S4412B introduces a system that lets contractors earn more on their total equipment investment by delivering more earth at faster speeds with lower operating costs and higher reliability.”

Key features of this scraper include tight integration with the Bell tractor, a rear wheel assembly based on a pair of massive 100 in. (254 cm) diameter E3 earthmover tires on 5 in. (12.7 cm) diameter axles, plus a High Arch Drawframe designed to optimize weight transfer and maneuverability.

Advanced Earthmoving Power

According to Kloepfer, the S4412B was designed for large, dedicated earthmoving projects and is optimized for both conventional push-loading operations and for top-loaded hauler/spreader operations. In some applications, said Kloepfer, the S4412B also is capable of self-loading.

The scraper bowl lists a struck capacity of 30 cu. yd. (23 cu m) and for heaped loads up to 44 cu. yd. The 4 piece cutting edge scrapes a 12 ft. (3.6 m) swath up to 13 in. (33 cm) deep, loading through an apron opening of up to 89 in. (226 cm). The bowl’s 73 in. (185.4 cm) high sidewalls minimizes spillage during loading and provides the S4412B with increased load retention to deliver more of the captured load to the dump location, according to the manufacturer.

The power unit is a 422 HP Bell 4206D scraper tractor driven by a 12-L Mercedes Benz diesel engine and Allison 6-speed automatic transmission. The smooth-riding tractor achieves top speeds up to 24 mph (39 kph), while the right-sized scraper tires ensure maximum flotation and stability over soft and uneven ground.

Strength and Agility

The scraper’s High Arch Drawframe couples the scraper and tractor through a 12 in. (40.4 cm) diameter ball hitch. The ball hitch is positioned well ahead of the tractor’s rear axle to take best advantage of the strength, speed, traction and agility designed into the unit specifically for scraper application.

The drawframe configuration effectively transfers loaded scraper weight equally to both tractor axles for maximum tractive effort in all soil conditions. The equalization of the tractive effort of both axles also efficiently distributes load stresses to ensure a long, productive lifecycle, according to the manufacturer.

The High Arch Drawframe’s compact connection also allows the 55 ft. (16.7 m) long scraper system to turn within a radius of just 39 ft. (11.8 m), enabling operators to maneuver quickly and safely on congested work sites.
