• 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.
• A rotor is equipped with a biased cylinder and further the rotor has 7 pieces of vane which is able to slide to radius direction. These are regarded as the rotary vane air motor that the air pressure makes a rotor rotate using 7 pieces of vane. • Reduction gears are engineered with planetary gear system composed of 2 step reduction(3 step reduction for EHL-1TS to EHL-6TW), which are capable of large reduction ratio and light and small. • Further gears are treated with heat and have sufficient strength. • Control valve is composed of a spring return type spool valve of direct driving, 3 positions and 5 ports. Valve is operated by a valve lever connected with a spool(valve cone) A disc brake is adopted for brake mechanism, which is durable and sufficient. The brake makes the most of air motor characteristics. • The surface hardened chains are used for ENDO air hoists and they are excellent for performing tightness and tough against wear.
OPTION • Pendant Switch This is available for button control instead of rope control. (AT series are available for only Pendant switch) • Over load protector This is available for operation stop actuated by air shut off in case of a load of over the rated load suspended.
