New towed scrapers from Cat
CATERPILLAR’s four new towed-scrapers – the TS180 and TS220, with two rear wheels; and the TS185 and TS225, with four rear wheels – feature heavy-duty design and large load capacities for enhanced productivity.
Heaped-capacity ratings for the new models range from 14.4 cu m for the TS180 and 14.5 cu m for the TS185 to 18.0 cu m for both the TS220 and TS225. All four models feature a durable bowl design, with high-strength, abrasion-resistant steel on the floor, walls, ejector and apron.
The box-section design of the bowl floor resists the stress of top loading and provides structural rigidity for intermittent push loading. Moreover, the cellular design of the walls resist load pressures and dents, while the ejector gate, fabricated from a single sheet of high-strength abrasion-resistant steel, moves on the same high-strength rollers used in Caterpillar’s articulated ejector trucks.
The bowl also features a centre-lift design, which eliminates the large external supports used in most conventional scraper designs. The rear cylinders on the four-wheel TS185 and TS225 models allow the operator to adjust the cutting-edge angle to best accommodate different soils. These models also feature walking-beam suspension for a smoother ride, reduced side sway and easier grading.
Because the scrapers can be used in tandem, ‘lead’ and ‘trailing’ configurations are available. Both configurations use a heavy-duty truss and push-block at the rear for intermittent push loading; lead units have a countersunk hitch that allows push loading when the unit works alone.
Standard equipment on the scrapers includes radial tyres, dry disc brakes, and heavy-duty oil-filled wheel hubs to ensure long service life.
