Continuous Movement Hydraulic Drive
Hydrostatic Drive OptionsChoose from two types of hydrostatic drives: worm gear or planetary. Both offer continuous movement and have no exposed, moving parts. T-L planetary gears are totally enclosed and they are coupled directly to the hydraulic motor eliminating the center drive gearbox and conventional U-joints. Other exposed moving parts are not part of the T-L design. T-L continuous move hydraulic drive motors and planetary gear drives are easily accessible in the event service is ever required. T-L offers the only planetary gear drive available on any center pivot system on the market today. In addition, the planetary gear boxes come standard with an 8 year/24,000 hour warranty. Continuous movement means extended gear life.
Alignment Control SystemT-L systems maintain alignment through the use of a simple hydraulic spool valve. The alignment system moves the spool valve, metering the required hydraulic fluid flow for each tower maintaining continuous movement and alignment with the end tower. This simple hydrostatic control is vastly superior to the start-stop microswitch design used with single-speed electric motor drives. Maintenance free, the spool valve is made of corrosion-resistant stainless steel. If a tower gets stuck or seriously misaligned, the valve will bypass hydraulic fluid through a return line to the pump, dropping the hydraulic pressure and stopping the system, preventing major damage. The T-L alignment valve carries a industry leading 8 year warranty.
|I don't know what it is, but I also don't seem to have as much trouble with the nozzles clogging up on the T-L units as I do with the other units.|
|We believe that with proper maintenance our T-Ls will run until they're 50 years old.|
