• Contribute to the improvement of working efficiency and worker's fatigue. • Suit the work of which high speed is required, such as material lifting etc. • Employ an air motor and no electric power is required. • Work with stepless speed control. • Include a reverse winding prevention device which actuates at 2m wire rope pay out. This is available for reverse winding prevention. (EHW series only) • Limitation mechanism is applied to EHL series.
• Air motor is engineered with rotary vane system which 7 pieces of vanes make a rotor rotate with air pressure. 7 pieces of vanes are equipped in a rotor installed in a biased cylinder and they are able to slide to radius direction. • Reduction gears are planetary gears which are small and light and further capable of large speed reducing ratio. Reduction gears are heat-treated gears. • Control valve contains 2 spool valves of spring return type which has 2 position and 3 port. Valve is operated by the lever switch connected to a spool. • Brake for EHW series realizes excellent braking capability due to both a durable and secured cone brake connected with a control valve and engine brake effect generated by a typical air motor.
