A sheave combination and drive belts power the T-Class. A variety of add-on components allow producers to outfit the machine with features to enhance their specific operation, according to the company. These include a dust enclosure, spray system, ball trays, special paint systems and more. Additionally, the company manufactures the machine with a stainless-steel construction, on a skid mount, or as a stationary or portable structure.

Producers can choose from machines ranging in size from 4-ft. x 8-ft. to 8-ft. x 20-ft., as well as 8-ft. x 4-ft. with a twin shaft. The standard model is inclined at 20 degrees, but variations between 15 and 25 degrees are also available.

The T-Class features a body with non-welded side plates, which the company says eliminates cracking along the seams. The shaft housing includes extra-wide flanges to allow Huck bolting through the tube housing flange, side plate and side plate stiffener. The company says this allows maintenance crews to keep the factory seal and creates a very rigid and solid connection to resist the high bending moments in this area.

The company designed the side plates to extend behind the bearing housing, allowing the 16 3/4-in. high tensile strength bolts to sandwich the side plate, reinforcing plate, shaft housing and bearing housing together. This creates more stiffness in middle of the machine where it’s most required to withstand bending and twisting. The manufacturer also forms the reinforcing plate with 90 degree vertical edges to give the side plate stiffness from top to bottom, tying the upper and lower decks together for additional strength. Rigid body brackets manufactured to withstand large static and dynamic loads support the body weight and carry through to the springs, ensuring smooth operation, according to the company.

Haver & Boecker also equips every cambered deck on a T-Class with its Ty-Rail quick-tensioning system, which cuts screen media change-out time by about 50 percent, according to the company. Each Ty-Rail package includes two tension rails, eight angle boxes and eight bolts. To remove the tension rails, an operator simply loosens the bolts on each, shifts the angle box gates up and lifts the rail and bolts out as one piece.

Operators can pair the T-Class with any type of screen media, including the company’s Tyler engineered media. This includes the long wear life of Ty-Wire, Ty-Max and Ty-Deck.
