Claims
- 1. A light weight portable rescue device having two arms which deliver rotational motion, therebetween, under very high loads, said rescue device comprising a portable heavy duty electric motor, and gear means for converting the output of the motor to a low controllable speed and high torque to at least one of said arms, said gear means comprising a rotary multiple stage gear box having a compound planetary output stage.
- 2. The light weight portable rescue device of claim 1, wherein said portable heavy duty motor is an electric motor capable of being powered by an electric battery.
- 3. A light weight portable rescue device having two arms for delivering a rotational motion, between said arms, under very high loads, said device comprising a portable heavy duty motor, and gear means for converting the output of the motor to a low controllable speed and high torque to at least one of said arms, said gear means comprising a rotary multiple stage gear box having a compound planetary output stage; wherein said device further comprises means for providing said high torque to at least one of said arms wherein said rotational motion is in a direction wherein said arms move toward each other and said device further comprises means for providing said high torque to at least one of said arms wherein said rotational motion is in a direction wherein said arms move away from each other.
- 4. The light weight portable rescue device of claim 3, wherein said arms comprise cutting means for cutting when said rotational motion is in a direction wherein said arms move toward each other and wherein said arms further comprise spreading means for spreading when said rotational motion is in a direction wherein said arms move away from each other.
- 5. A light weight portable rescue device having two arms for delivering a rotational motion between said arms under very high loads, comprising a portable heavy duty motor, and gear means for converting the output of the motor to a low controllable speed and high torque to at least one of said arms, said gear means comprising a rotary multiple stage gear box having a compound planetary output stage; with said arms being replaceably removable from said device, and wherein said device further comprises means for providing said high torque to at least one of said arms wherein said rotational motion is in a direction wherein said arms move toward each other and said arms comprise cutting means and said device further comprises means for providing said high torque to at least one of said arms wherein said rotational motion is in a direction wherein said arms move away from each other and wherein the arms comprising cutting means are replaced with arms comprising spreading means.
- 6. The light weight portable rescue device of claim 5, wherein said portable heavy duty motor is an electric motor capable of being powered by an electric battery.
- 7. A light weight portable rescue device having two arms which deliver rotational motion, therebetween, under very high loads, said rescue device comprising a portable heavy duty electric motor, and gear means for converting the output of the motor to a low controllable speed and high torque to at least one of said arms, in which one arm is attached to and movable with the outside of a ring gear which is driven from its internal side by said gear means.
- 8. The light weight portable rescue device of claim 7, wherein said portable heavy duty motor is an electric motor capable of being powered by an electric battery.
- 9. The light weight portable rescue device of claim 7, wherein said device further comprises means for providing said high torque to at least one of said arms wherein said rotational motion is in a direction wherein said arms move toward each other and said device further comprises means for providing said high torque to at least one of said arms wherein said rotational motion is in a direction wherein said arms move away from each other.
