T-Lís hydrostatic drive offers many features not available on electric pivots. Unlike the stop-and-go action of electric models, each tower on a T-L system moves continuously. This is especially beneficial on low-pressure systems where uniform water application is critical for irrigation-applied fertilizer, herbicides and pesticides. Chances of a T-L tower getting stuck are reduced because of the improved traction that continuous movement provides on wet, rough terrain. A constant, smooth rate of travel also reduces wear on all drive components, while eliminating the wasteful power surge required to get a stopped tower moving again.
There is no wasted horsepower with a T-L because the power required to run the pump varies directly with the rotation time of the pivot. All T-L Irrigation Systems utilize non-toxic Hydroclear™ hydraulic fluid with an additive package specially designed to provide superior wear protection. The filtered hydraulic system assures long life.
Choose from two types of hydrostatic drives: worm gear or planetary. Both offer continuous movement and have no exposed, moving parts.
T-L planetary and worm gears are totally enclosed and they are coupled directly to the hydraulic motor, eliminating a center drive gear. Conventional U-joints and other exposed moving parts are not part of the T-L design. Motor and gear drives are easily accessible in the event service is ever required.
T-L towers feature a heavy-duty pipe base and four vertical angle iron tower supports as a welded and dip-galvanized structure. Heavy-duty tower braces provide additional stability necessary for rugged terrain and furrowed conditions.
Heavy-duty galvanized rods with truss tabs notched before welding allow for uniform stress on the truss rod connection. One bolt could hold the connection, but T-L uses two grade 5 bolts to reduce the shearing force on each bolt. It is another feature that keeps a T-L running trouble free &em; longer.
The T-L system features an extra tough external flex-joint, designed to withstand uneven and rolling terrain. The external flex-joint design assures a full flow of water with minimum pressure loss and turbulence.
We begin with heavy-duty steel mainline pipe, truss rods and tower structures. All are galvanized in T-Lís own modern facility to ensure uniform quality. The hot-dip galvanization process chemically seals the steel components. Our heavy-gauge mainline pipe is rolled into varying diameters for maximum water-flow, minimized friction loss and reduced pumping costs. Automatic drains at every tower empty the system after each use.
You can control your rotational speed and direction with two simple hydraulic valves. With years of field-proven operation, the Manual Speed and Direction Control option is the industryís simplest, most reliable management tool.
Features independent forward, reverse, and auxiliary speed setting by field position from the control panel. The pivot can also be stopped or reversed at predetermined positions. System speed information is shown for precise water application and there is a large backlit screen for easy viewing. This control has the major features of the TLC Pivot Manager without the complexity of computer programming.
You can control pivot speed and direction from the pivot point or remote locations other than the end tower.
The next generation of computerized pivot management from T-L. Reports operational performance, controls multiple system outputs, provides readings for water and hydraulic pressures, monitors speed, sets a watering schedule and more.
Can be utilized on all T-L management systems. Communication can be designed with a cellular or radio connection to fit your specific requirements.
T-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 valve spool 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, stopping the system and preventing major damage. Sensors shut down watering simultaneously with the system.
