Product introduction of high lift hoist High lift hoist It can be divided into single point type and mobile type. The operator must master the structure, performance and operation method of the hoist, and have certain mechanical knowledge to ensure the normal operation of the machine. 2. Check whether the bolts are in good condition before shut-down and check whether there is any looseness before starting. Check whether the power line is connected and whether the switch is in good condition when the electric switch is on.
Classification of high lift hoist
High lift winch hoist is divided into fixed type and mobile type, and has single lifting point and double lifting point for users to choose. Its specifications mainly include: QPQ ordinary winch hoist, qpk fast winch hoist, qpg high lift winch hoist, QHQ radial gate winch hoist and QPT mobile winch hoist. Manual device can be added according to the user's needs. The opening and closing tonnage of the above products is 6-125t, which can be used with flat plate and radial gate. It is suitable for large, medium and small reservoirs, rivers and water conservancy and hydropower projects.
Installation precautions of high lift hoist;
During installation, the foundation of the base shall be firm and flat, with the position of foot screw reserved. After the hoist is in place, it shall be leveled and poured into shape.
At the same time, wind the steel wire rope on both ends of the drum and fix the rope on both ends of the balance pulley.
High lift hoist hoist commissioning ：
1. Under the condition of no load, the unbalance of three-phase current shall not exceed plus or minus 10%, and the current value shall be measured. 2. Adjustment of upper and lower limits: when the gate is fully closed, press the upper limit on the upper travel switch and fix it on the screw. When the gate is fully open, press the lower limit plate down the travel switch and fix it on the screw. 3. The adjustment of the master controller of the hoist must ensure that the error when the gate is lifted to the upper and lower limit is not more than 1cm. 4. After installation, trial operation must be carried out. Once no-load test is carried out, that is, the screw is allowed to make two strokes to hear whether there is abnormal sound and whether the installation meets the technical requirements. Second, load test, under the rated load, make two strokes, observe the operation of screw and gate, whether there is any abnormal phenomenon. It can be put into operation only after confirmation.
1. The operator must master the structure, performance and operation method of the hoist, and have certain mechanical knowledge to ensure the normal operation of the machine. 2. Before operation, conduct a comprehensive inspection on the hoist to see if the lubrication of each part is good and whether the bolts are loose. Check whether the power line is connected and whether the switch is in good condition when the electric switch is on. 3. During electric operation, operators are not allowed to leave the site and stop the machine immediately when problems are found. 4. When the machine is shut down, the load must be removed. 5. In use, it is necessary to inject lubricating oil from the oil injection hole at any time, and keep enough lubricating oil. The screw rod should be regularly cleaned of oil dirt and coated with new oil to prevent corrosion.
