Toledo, Ohio-based Dana Holding Corporation recently launched a new generation of drivetrain systems for front-end loaders and telescopic boom handlers that meet the demands of construction and material-handling vehicles.
Dana's driveline system for side-mounted cab telescopic boom handlers is designed to accommodate the increasing sizes of these vehicles while supporting increased productivity, higher reach, higher lift capacity, and greater versatility. With up to a 5-ton lift capacity, the system is composed of two S picer Model 223 axles and a Spicer HSY08 powersynchro transmission.
Building on the success of the Spicer HSR08 powershuttle transmission introduced at Bauma Munich 2007, the Spicer HSY08 powersynchro transmission offers either electric or automated range shifting with improved controllability. The Spicer HSY08 powersynchro transmission has a low overall length to accommodate the short wheelbase of telescopic boom handlers, with lateral offset of outputs supporting parallel side-engine installations. An engine-dependent mechanical PTO for implement drives is available as an option.
Specifically designed for five-ton telescopic boom handlers, the Spicer Model 223 front and rear axles feature a spring-applied hydraulic-released (SAHR) park brake in the center of the axle to enhance overall safety. The axles' oil-immersed wet brakes facilitate excellent performance and extended life, and differential lock options provide improved performance in difficult operating conditions.
Dana also launched the Spicer Model 369 shift-on-fly hydrostatic transmission, which provides an alternative to expensive powershift solutions or sliding collar range shift transmissions. The Model 369 transmission was specially designed to enhance mobility, comfort, and ease of use for operators in mid-sized construction and material-handling vehicles.
The Spicer Model 369 transmission is a cost-effective means of allowing seamless operation from reverse, full stop, and all the way to speeds of more than 24 mph. Vehicles equipped with traditional range shift solutions must completely stop before shifting between ranges, but the new gearbox on the Spicer Model 369 transmission allows for quick shifting from low to high range while moving.
This transmission is composed of a single hydrostatic motor featuring a transfer case with low and high gear ratios that integrates the drivetrain system into the engine's controller area network (CAN) to improve shift quality and reduce acceleration jerk during vehicle operation.
The Spicer Model 369 transmission builds on the success of previously released Spicer shift-on-fly hydrostatic transmissions designed for telescopic boom handler, front-end loader, and wheeled excavator applications. The Spicer Model 369 transmission offers a compact layout with a 5.9-inch drop and can be remote-mounted as well as vertically or horizontally flanged to the axle. This transmission is also available with an optional spring-applied hydraulically released park brake, which reduces the number parts and eliminates the need for a separate external park brake.
“Dana's hydrostatic transmissions have already been used in more than three dozen different customer applications,” said Rick Honeyager, director of product planning for the Dana Off-Highway Products Group. “The Spicer Model 369 transmission has received a particularly enthusiastic response from European OEMs, and we are seeing increased interest from North American OEMs looking to develop compact vehicles with hydrostatic solutions.”
