Large manipulator, especially for self-propelled concrete pumps

A truck mounted concrete pump comprising:

• a vehicle frame;
• a mast base pivotally mounted on said vehicle frame;
• a first drive means for rotating said mast base relative to said vehicle frame about a vertical pivot in one of a first direction of rotation and a second direction of rotation;
• an articulated mast positioned on said mast base having at least three mast arms, said at least three mast arms being pivotal about horizontal axes therebetween, a last mast arm of said at least three mast arms distal said mast base has a tip at a distal end of said last mast arm orientable at a select height;
• a second drive means for pivoting selected ones of said at least three mast arms about said horizontal axis;
• a computer-assisted coordinate transmitter having a means for controlling said first and second drive means, a storage means for storing path-swivel characteristic data of said articulated mast, and a first transceiver;
• and a radio remote-control device having a first control lever and a second transceiver, said first and second transceivers being electromagnetically connected along a radio path, said first control lever including means for facilitating movement of said first control lever in four directions and a means for emitting a first control signal in response to a movement of said first control lever in a first direction of said four directions to said second transceiver, said second transceiver including means for transmitting said first control signal to said first transceiver along said radio path, said first transceiver including means for transmitting said first control signal to said computer-assisted coordinate transmitter, said computer-assisted coordinate transmitter including means for converting said first control signal into a coordinate signal for said means for controlling said second driving means to effect a radial extension of said articulated mast with said tip at said select height.
