INFLUENCE OF LENGTH OF TIP HORSE AND POSTURE ON OVERLOAD OF BOOM DEVICE IN BOOM OPERATION OF PLACING CONCRETE BY PUMPING METHOD

Abstract

This paper deals with consideration in boom operation changed length of tip horse to boom and posture of boom in placing concrete by pumping method. Therefore, Quality variation of concrete after pumping show a tendency to almost equal in length pipe for boom. Pressure line for boom should be consideration that length extended pipe line is longer. In addition, Posture of boom should be consideration that take measures to prevent overload for boom as much as type M keep.
