Skyjack's TH series is engineered to require NO DPF (Diesel Particulate Filter), NO DEF (Diesel Exhaust Fluid), and NO other active exhaust after treatment on standard engines. By utilizing improved gearing, high torque engines and a simplified, high efficiency hydraulics package, the TH series is able to employ 74hp engines to deliver the same on-site job performance as higher power units. In addition this allows for improved residual value as a simple more reliable machine competes positively with active emission controls. This solution is much more than the simple use of a 74hp engine and involves optimizing gearing and axle ratios, utilizing an enhanced torque convertor optimization and the development of other synergies through the use of Deutz engines, Dana powershift transmission, and Dana axles.
