The Spicer® Model 114 (33R092) Hercules™ front axle and Model 113 (29R053) rear axle, a Spicer® 319 summing motor, and the compact Spicer® 2035 Series driveshaft are combined as an optimized drivetrain solution for 16-ton front-end loader vehicle applications.

The Model 114 (33R092) axle is the latest addition to Dana’s program of products for front-end loader vehicles, and completes Dana’s axle offering to enable accommodation of vehicles with 3- through 50-ton operating weights.

Engineered for vehicles with operating weights of up to 15 tons (in front-axle applications) and 18 tons (in rear-axle applications), the 114 (33R092) axle is specifically designed to address the needs of the mining and forestry industries. The Model 114 axle includes 6.00-to-1 outboard planetary wheel ends with 425mm wheel B.C. mounting, self-adjusting internal wet brakes, a trunion mounting option, and several torque-biasing differential and park brake options.

This system also features a Spicer® 319 summing motor transfer case, providing maximum tractive performance and high efficiency, as it delivers seamless CVT (continuous variable transmission) performance from 0 to 40 kph. The transfer case was designed to accommodate the most cost-effective hydrostatic components as each motor is connected to its own gear ratio. In addition, a disconnect clutch is fastened to the low-speed, high-gear-ratio motor, allowing only the motor to efficiently power the vehicle at higher travel speeds.

Engineered for 15.5- to 17.5-ton wheeled excavators, this driveline is composed of a Spicer® Model 263LD (26SW053) front axle, a Spicer® Model 163LD (26RW053) rear axle with a directly flanged Spicer® Model 369 shift-on-fly hydrostatic transmission, and a Spicer Life Series® 55 driveshaft.

The rear axle’s Spicer® Model 369 shift-on-fly hydrostatic transmission is an innovation that enhances mobility and ease of use for operators. It features advanced control technologies also found on the previously released Spicer® Model 367 shift-on-fly hydrostatic transmission designed for teleboom handler applications.

Dana also recently enhanced its axle product offering to include a new brake option with wheel speed service and parking brakes, as these rugged vehicles require a braking system that is positive and reliable. On wheeled excavators, the outboard brakes act directly on the wheel hub, rather than being located inboard, connected to a lengthy axle shaft.
