Patent Images
1. A remote control hazardous material handling device comprising:
- a movable base;
an upstanding support pivotally secured to said base;
a vertically adjustable support arm mounted on said upstanding support and extending generally horizontally therefrom;
a horizontally adjustable gripper mounted on said support arm and comprising an adjustable closed-loop cable extending from diverging ends of a Y-shaped conduit;
a first electric motor and drive means operatively associated with said support arm for vertically motivating said arm;
a second electric motor and drive means operatively associated with said gripper for horizontally motivating said gripper;
a third electric motor and drive means operatively associated with said upstanding support for pivotally motivating said support;
a first remote control means electrically connected to said electric motors for controlling said motors from a remote location; and
a second remote control means operatively associated with said gripper for controlling engagement and disengagement of the hazardous material by said gripper.

Abstract
A hazardous material handling apparatus capable of being remotely controlled so as to allow the operator to safely handle hazardous materials. The apparatus utilizes electric motors in order to provide for three-dimensional movement of the gripper. A television camera and remotely located television monitor may be utilized in order to facilitate remote control of the apparatus. A manually operated gripper is provided to allow for simple and inexpensive construction.
