Electric actuators are quickly replacing hydraulic cylinders in mobile off-highway vehicles. They eliminate bulky hydraulic pumps, cumbersome hoses and valves, and minimize environmental damage from unavoidable fluid leaks. Electric actuators also increase operator safety and reduce fatigue with simple, easy-to-use controls. They can push and pull heavy loads and do not depend on ancillary brakes, directional control valves, or the load itself to hold position.
“Thomson’s ElecTrak Pro Series linear actuators bridge the gap between common linear actuators that do not meet the needs of tough, mobile, off-highway (MOH) applications and expensive precision linear actuators that have attractive advanced operation and control options, but can leave MOH design engineers reaching for the hydraulics and pneumatics because of their cost,” says Mark Maybee, Linear Actuator Business Unit Director.
Electronic load monitoring (ELM) continuously monitors all critical parameters and acts as an electronic clutch, stopping the actuator at end of stroke and mid-stroke overload. ELM also provides dynamic braking for consistent, repeatable stops, and holds the load with power off. It also uses low cost switches to control the actuator. The series suits tough, space restricted MOH vehicle applications, such as lawn and turf care, floor maintenance, utility, and construction vehicles.
