Abstract

The present invention relates to a spring and hydraulic damper for gate barricade comprising: a base (10), a pair of bush bearings (1 1 ), a shaft (12) including a sprocket (13); an actuator mechanically connected to the sprocket (13) to drive rotational motion of the shaft (12); and characterized by: a pair of L-shaped brackets (20) coupled to the shaft (12); a pair of adjustable dampers (21) including a head (22) and a threaded body (23), secured to both ends of each said L-shaped brackets (20); a pair of springs (24) parallel to each other and mounted on the base (10) adjacent to said shaft (12), wherein the pair of springs (24) absorb force from the shaft (12) when the pair of adjustable damper (21 ) is in contacts with said pair of springs (24); a pair of hydraulic cylinders (40); wherein the pair of hydraulic cylinders (40) is mounted on the base (10) adjacent to said shaft (12) and reduces shaking effect at the shaft (12) when said pair of adjustable dampers (21 ) contact with said pair of hydraulic cylinders (40).
