Our company is the main business of Water Resources designated production hoist gate, strong technical force, advanced equipment and perfect. Its products are closed strong, reliable quality, the majority of users and trust, and its products are exported all over the country, for the cause of China's water conservancy made a great contribution. Main products: 1, screw hoist 3T-100T; push LOCK, fully enclosed 0.3T-30T; screw-side rocking 0.5-2T; screw hand-cranked flashlight dual-use 3T-100T (single double hanging); 2, iron gates, high pressure cast iron gate, double sealing gate, the plane sliding steel gate, flat fixed wheel steel gate, inlaid copper iron side gate, inlaid copper round iron gates, adjustable weir gate, shoot the door (tide gate), one-piece door gate, gate, gate stacked beam, stainless steel gates and so on. 3, QPQ type, QPK type, QPG type, QPT type, QHQ type winch hoist (single, double hanging). 4, HGS- rotary grate discharge machine, HGC- rotary grate discharge machine, FHG- anti-fishing grate discharge machine, XHS rotary grate discharge machine, GLGS- high chain grille except dirt machine, YZL- spiral grate discharge machine, PLS- flat grille. 5, rubber water stop 651, 652 type, 653 type, type, and other water swelling rubber water stop, rubber seal has P60, P50, P45, P35, and various internal and external corners, flat, bridge bearings, etc. can also be made of a variety of special rubber products based on user requirements and processing: hoist including motor, hoist, racks, shields and other components; three-stage deceleration mode, with spiral auxiliary transmission output torque more great. Hoist supporting steel overcome civil irregularities, in order to reduce overall noise and vibration. 2, using outdoor long duty motor, protection class ≥IP155. Stroke control mechanism decimal counter principle, control error of 0.5% stroke. Torque protection control is touched by the worm axial displacement micro switch, to achieve the protection of electrical principles. 3, easy operation and maintenance, enabling on-site and remote control operation. Two: a hoist safety procedures. Construction units, to hoist should be installed on a flat solid, good view of the ground, the body and must be firmly anchor. Requirements hoist should be vertical centerline of the guide pulley alignment, distance pulley hoist should generally be not less than fifteen meters. 2. Before transfer loading operations, should check the rope, clutches, brakes, insurance ratchet drive pulleys, etc., to determine the safe and reliable operation only. Wire rope on the drum must be neat, jobs need to retain a minimum of three times. When the job, it was not allowed to cross the wire rope hoist by preventing accidents. 3. When lifting heavy objects need to stay in the air, in addition to the use of brakes outside, and apply the ratchet insurance card prison. When the operation is strictly prohibited without permission to leave their posts. 4. Work to obey the command staff of the signal, the signal is unknown or may cause an accident, you should suspend the operation until after clarifying the situation may continue for hoist industry. Jobs sudden power failure, should immediately pull the knife, and the delivery of objects down. Three: Load Test Method 1, hoist hoist operator must master the structure, properties and methods of operation of the hoist, and have some mechanical knowledge, in order to ensure the normal operation of the machine. 2, before the operation, to conduct a comprehensive inspection from the closed machine, each part of the lubrication is good, loose bolts. Hoist 3, when the hoist operation, the operator shall not leave the scene, they found the problem immediately shut down. 4, machine maintenance, load must be removed. 5, when used, need to inject lubricant at any time by filling hole, enough oil to keep the screw to regularly remove grease, oil coated the new guard, to prevent corrosion.
