A RECIPROCATING PISTON CONCRETE PUMP HAVING A FORCE MULTIPLIER CUM AUTOMATIC OVERLOAD PROTECTION & DISENGAGING DEVICE SEPARATE FROM ITS DRIVE MECHANISM

摘要

In accordance with the present invention, "A reciprocating piston concrete pump having a Force Multiplier Cum automatic overload protection & disengaging device separate & independent of its drive mechanism" which typically & essentially consists of an improved reciprocating piston concrete pump having an additional hydraulic cylinder (7) separate from its drive mechanism, mechanically installed between the reciprocating piston (1) and the mechanical linkages (10) wherein the said hydraulic cylinder (7) is provided with a static fluid (18) confined and enclosed between two differential areas ( 11 & 12 ) and the smaller area is mechanically connected to the mechanical linkage (10) for application of input force and the bigger area is mechanically connected to the reciprocating piston (1) for exerting force on concrete. The said hydraulic cylinder (7) performs various functions such as multiplication of force in accordance with the Pascal's principle; overload protection and manual disengagement of pumping action.
