#CMT# #/CMT# The bollard (A) has a mobile marker in which a support plate (M) is housed, where movement of the bollard is activated by a hydraulic jack (F) without an internal or external motorization. The hydraulic jack is fed by a double direction hydraulic pump (B) rotated by a drilling machine or screw driving machine (G) that is handled by an operator for permitting rising and descending of the bollard by reversing rotation direction of the screw driving machine. The pump aspires hydraulic oil in a reservoir (C) through a drilled block (D). #CMT#USE : #/CMT# Retractable hydraulic bollard for prohibiting access to a vehicle in a reserved parking place. Uses include but are not limited to prohibit access to the vehicle in the reserved parking place in a market, superette, bank, automated cash dispenser and walkway. #CMT#ADVANTAGE : #/CMT# The hydraulic jack is fed by the double direction hydraulic pump rotated by the drilling machine or screw driving machine that is handled by the operator for permitting rising and descending of the bollard by reversing rotation direction of the screw driving machine, thus permitting the bollard to be positioned without using electrical elements, and permitting the bollard to be perfectly immersible and insensitive to the gel, and hence simplifying installation of the bollard. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a three dimensional view of a component assembly in a mobile marker of a retractable hydraulic bollard. A : Retractable hydraulic bollard B : Double direction hydraulic pump C : Reservoir D : Drilled block F : Hydraulic jack G : Drilling machine or screw driving machine M : Support plate. |
