AN INTEGRATED LIFTING ARRANGEMENT AS TWO POINT LINKAGE TO ATTACH AND LIFT ANY IMPLEMENT TO A VEHIVLE

摘要

NAME OF THE APPLICANT: Ms. JAYANTHI JAYACHNADRA RAO 7. ABSTRACT OF THE INVENTION An integrated lifting arrangement as two point linkage to attach and lift any implement to a vehicle is simple, very economical and time saving in vehicles or stationery machineries. This implement (10) lift arrangement consists of a Hand operated hydraulic device (3) connected to of a jack or Hydraulic RAM cylinder (8) through a Hydraulic non-return valve (6) and a hydraulic hose (7). The piston RAM cylinder (9) of the jack or Hydraulic RAM cylinder is located right under the half round metal pad (17) which is an integral part of the lift arm side bars (11) of two point linkage (22). The piston RAM cylinder (9) of the Hydraulic RAM cylinder (8) gets lifted when the lever hydraulic device (5) is pressed by the driver sitting in his seat. Since overhang distance of the lift arm side bars (11) or the distance (y) between the half round pad (17) and the implement attaching snap pins (15) is larger as compared to the distance (x) between hitch pin lift arms (13) and the half round metal pad (17), the lift leverage of piston RAM cylinder from a zero level height (A) to (A1) on the two point linkage (22) at the point of half round metal pad (17) effects in larger lift of the implement (10) from (B) to (B1) proportionately to the ratio of the distance (y) between implement mounting snap pins [(15),(15)] and half round metal pad (17), and the distance (x) between half round metal pad (17) and the two hitch pins [(13), (13)]. The implement (10) is lowered from height (Bl) to (B) by opening the hydraulic nonreturn valve (6) when the hydraulic fluid flows back from the hydraulic RAM cylinder (8) to the hand operated hydraulic device (3) thus bringing back the half round metal pad (17) from a height of (Al) to (A) resulted by the gravity of the implement (10).
