Electro-hydraulic grab HERCULES ®

Characteristics: Valves.- two of special design and great robustness, built with electro welded plates in carbon steel of A/42-b quality, provided inside with reinforcements. Characteristics: Valves.- two of special design and great robustness, built with electro welded plates in carbon steel of A/42-b quality, provided inside with reinforcements. Amphibian.- the body and structure are built in electrically welded laminated steel plate. Inside it contains the oil storing deposit, electric engine, all the components and valves. In the upper part the housing of the toric joint is mechanized and is covered with a lid in which a rubber joints system is installed, which warrantees the fastening of the electrical cable and the total sealing. The spoon is submergible up to a 25 mts depth. Auto press.- powering will be electro hydraulic by means of a hydraulic cylinders in inclined position that exteriorly act over the valves, exercising a pressing action over the material container inside the valves. Electric engine.- 1.500 r.p.m., 220/380 V, 50 Hz, Ip-55 protection, class F isolation. (Siemens or similar). Hydraulic cylinders.- two special of reinforced design, double effect, rear damping, submergible, rectified and plated stems. Hydraulic cylinders protections.- such protections are incorporated in their pistons, with the purpose of protecting them from any deformation or breakage, the construction will be in carbon steel of A/42-b quality. Maximum pressure.- 150 Bars. Closing- opening maneuver.- by means of electro valve, double 24 V magnet, Dc 4 ways, 3 positions, center By-pass. Hydraulic oil.- Hydraulic 225, or similar included.
