Xin, professional hoist manufacturer, Ministry of Water Resources designated procurement units, R & D, production, sales hoist, gates integrated manufacturers, into the design, casting, machining, assembly as one of professional production companies . The main products for water use gates, hoist, engineering rubber. Such products for all kinds of water, electricity, urban water supply and drainage, sewage treatment, drainage pumping stations, irrigation, aquaculture and other projects. Screw hoist installation steps: 1, the installation of the screw hoist must maintain a base level of basic layout plane 180o; hoist the base and foundation furnished flat contact area to reach more than 90%; screw axis to be perpendicular to the gate station the measure of the level; to the gate lug holes and vertical text, avoiding screw tilt, causing local stress and mechanical damage. 2, will be placed in a manual screw hoist installation location. The disc sets a limit on the screw, the screw from the lower portion of the beam onto the machine, after the screw is exposed from the top of the machine, and then put on the stopper plate. Beneath the gate of the screw connection. 3, for the installed base must be firm and safe hoist. Base and concrete foundation member, according to the provisions drawings pouring concrete strength at the time did not meet the design strength, are not allowed to remove and change the temporary support hoist, but can not reconcile commissioning trial. 4, when installed according to the centerline of the gate lifting, aligning the center so that the vertical and horizontal centerline deviation does not exceed plus or minus 3mm, elevation deviation does not exceed plus or minus 5mm. Then pouring concrete or connected with two embedded steel. 5, for the installation of electrical equipment products, must comply with drawings and specifications, and all the electrical equipment are reliable ground. 6, the product is installed, the machine must be cleaned, Repairing damaged protective paint, perfusion lubrication
