When no operation of the aerial device isactivated, the pump shall rotate on minimum flow and minimum pressure. When one of themovements is operated the control valve automatically increases the pressure to a pre-set constantlevel and the oil flow to the amount that is needed for the movements activated. The flow of thepump shall be sufficient to give the supply of Hydraulic oil at required pressure to all themovements activated simultaneously at full stroke without affecting the preset speed.13.3 There shall be a provision of instant couplings for attachment of manometer in each pressure linefor checking pressure of each circuit.13.4 The filtration system of the hydraulic oil shall consist of suction strainer in the suction line,pressure filters in each pressure circuit, return filter in return line and air filter on the reservoir. Allthe pressure filters shall have blockage indicator.13.5 All hydraulic cylinders shall be double acting with hard chrome plated piston rods and shall befastened by means of self-aligning ball bearings to prevent lateral forces from damaging the sealsor piston rods of the cylinders.13.6 Hydraulic oil tank shall be integrated into the main frame and shall have a proper heat dissipationsystem. The tank shall be fitted with oil level gauge, temperature gauge, and suction connectionswith closing valves for easy maintenance and draining outlet with closing valve.SIGNATURE & STAMP OF BIDDER43
