Shandong, China is set to build a hydraulic straight rail development / manufacturing / service integration modern enterprises. Model is complete, National Direct 15,263,722,267 technical performance and a brief description of YZG-800 hydraulic straight rail is a horizontal line on the rail direction make straight (or bend) the manual hydraulic special tools. Light aircraft weight, simple operation. When used, the straight rail hook hook head side, the piston head against the rail head on the other side, then turn the eccentric hand wheel, the straight rail lock on the rail, then tighten the oil drain valve, insert crowbar, you can be straight-rail operations. Work is completed, loosen the oil drain valve until the piston retracts, and then reverse rotation of the eccentric hand wheel, you can be under the direct rail elevation from the rail. Pump oil before loading should be checked straight rail mounted on the rail status, should be flat straight rail, hooks on the bottom surface of the rail to be snapping the top surface, the eccentric and the piston head and hooks at both ends and sides of the rail head shall good contact. When the oil is loaded pump action is not easy too fast. Maintenance: 1 oil must be kept clean, when oil was found dirty, sticky, or poor storage tank must be removed, after the oil industry with a detergent or pure alcohol to clean, clean note No. 10-20 plus mechanical oil. 2. Dismantling the suction valve, first unscrew the pump, remove the gasket and 6 mm steel ball cleaning. 3. demolition detected oil valve, unscrew the bottom of the back cover of the 12 mm hex screws, order take out ball, spring cleaning. 4. When you check the oil drain valve removed, can be screwed open valve, then remove the rubber seal ring and ball cleaning. The main technical parameters 1. Maximum straight track force 800KN 2. Working stroke 70mm 3. No-load efficiency of 1.8 / times 4. Maximum operating force 300-400N 5. Weight 80Kg 6. mechanical oil 10-20 # YZG-800 hydraulic straight track 1. Maintenance of the oil must be kept clean, when oil was found dirty, sticky, or poor storage tank must be removed, after the oil industry with a detergent or pure alcohol to clean, clean reraise 10-20 machine oil. 2. Dismantling the suction valve, first unscrew the pump, remove the gasket and 6 mm steel ball cleaning. 3. demolition detected oil valve, unscrew the bottom of the back cover of the 12 mm hex screws, order take out ball, spring cleaning. 4. When you check the oil drain valve removed, can be screwed open valve, then remove the rubber seal ring and ball cleaning. Applicable 43,50,60 track.
