Practice a hoist. Construction units, to hoist should be installed on a flat solid, good foundation vision hoist gate, 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 external hoist brake and apply ratchet insurance card prison. When operating winch hoist, to leave their posts without permission is strictly prohibited. 4. Screw hoist, should be suspended operations work to obey signal commanding officers, the signal is unknown or can cause accidents, to be clarifying the situation may continue for hoist industry. Jobs sudden power failure, should immediately pull the knife, and the delivery of objects down. Gates, hoist the spillway gates and do not have to set the shutter two kinds. Set the shutter 滋洪 road can drop the water level normal rules and door top flush flood sluice can quickly reach a large amount of leakage. Compare it with no gate control 滋洪 Road, the required flood storage capacity is small, can reduce the reservoir inundation losses, especially in case of floods often, you can not raise the water level in the reservoir operation is also more flexible venting. Of course, setting the gate will increase the project cost and management of maintenance work. So for a specific channel should not set in 滋洪 gates to determine many comparisons to be. Generally no more than a small reservoir gates, larger, more importantly, a better reservoir management agencies can set the gate. Ta flood gates set to be equipped with road gates, hoist. Set pan or no gate spillway may need transportation bridge and block fish passage facilities.
