WHEEL LOADERS
Dressta wheel loaders have earned excellent reputation among contractors, quarry operators and surface mining people worldwide. Improved and recently enhanced 500-Series wheel loaders guarantee a high production at low cost.
The loader train system is comprised of a modern diesel engine unit, torque converter, transmission, front and rear drive axles and driving shafts with articulated joints. These components provide the most reliable and durable power transfer system. This Heavy-Duty Power Train guarantees a high production at low cost.
Powerful turbocharged diesel engine in line cylinders deliver heavy duty torque synonymous with premium high horsepower and maximum efficiency at low cost while meeting the current emission standards requirements.
Torque converter three element, single phase, single stage automatically modulates engine power flow thru fluid coupling that effectively matches against the load and absorbs drive train shocks.
Power shift, countershaft transmission shift shock eliminated with smooth modulation of all shifts provides a high comfort during job performance. Countershaft transmission module with constant gear mesh is adjustment free, minimum parts needed for service and repair. A design, which provides long time, trouble free usage for outstanding profit.
Heavy duty axles design for specific heavy loads and stresses during tough loading/unloading operations. Axles employ all high strength elements resposible for power transfer to the driving wheels. Four wheel hydraulic wet-type brakes (C-series) - a completely sealed and adjustment free multiple oil disc brakes acting in two independent hydraulic brake circuits one for front, the other for rear wheels that reduce downtime, improve reliability and safety during loader use.
Z-bar linkage design transfers maximum breakout forces to the bucket to pry out hard packed material and do it with a single bucket cylinder. This design puts less weight on the front, has less components and less wear and maintenance points. All loader linkage pins are sealed, to keep out abrasive dust or grit and to extend lubrication intervals as well as pin-bushing life. Boom cylinders are mounted outside the front frame for easy access and maintenance.
