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.
This is available for button control instead of rope control.
|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.|
