Electric wire rope hoist detailed steps for the installation and maintenance
1, the newly installed or installed after dismantling the wire rope electric hoist, should first be empty commissioning several times. But not pre-installed, avoid power-commissioning.
2, should be carried out before the normal use of 125% of the rated load, lifting off the ground about 100 mm, 10-minute static load test, and check whether it is normal.
Dynamic load test is based on the rated load weight for repeatedly lift and move around test after test to check the mechanical transmission parts, electrical parts and connected parts is normal.
4, in use, the absolute prohibition of in disallowed environment, and more than the rated load and hourly rated closing times (120 times) the case.
5, installation, commissioning and maintenance must strictly check limit device is flexible and reliable, when hook up to the upper limit position, the hook shell to roll the shell of the distance must be greater than 50mm (10t, 16t, 20t must be greater than 120mm ). When the hook down to the lower limit position, should ensure the the reel wire rope safety circle, the the effective security ring must be more than 2 laps.
6 are not allowed at the same time pressing two electric wire rope hoist movement in the opposite direction of the flashlight door button.
7, after the work must be the power of the total gate opened, cut off the power supply.
8, electric wire rope hoist by hand manipulation, the manipulator should fully grasp the safety procedures, non hanging crooked pull oblique.
9, must be in use by specialized personnel regularly inspect the wire rope electric hoist, found that the failure to take timely measures, and carefully recorded.
10, electric wire rope hoist brake decline in the amount of adjustment, should ensure that the rated load, the brake slipped amount S ≤ V/100 (V liter from the stable load in the next minute distance).
11 wire ropes scrapped standards: wire rope inspection and end-of-life standards CB/T5972-1986 "lifting wire rope electric hoist machinery wire rope inspection and retirement of practical specification implementation.
12, the use of electric wire rope hoist must keep enough oil and lubricants clean, and should not contain impurities and dirt.
13, wire rope oiled, should use a stiff brush or small wooden tablets, non-oil hand directly to the working rope.
14 wire rope electric hoist does not work, do not allow the weight suspended in the air, to prevent parts from permanent deformation.
15, in the use of the process, if we find fault, should immediately cut off the main power supply.
16, should pay special attention to the use of consumable parts.
17, 10 to 20 tons gourd in continuous operation for a long time, the automatic power-off phenomenon, belonging to the motor overheating protection function, which may be reduced at this time, over a period of time, you can continue to work until the motor has cooled down.
18, the use and management JB9009-1999 "wire rope electric hoist safety procedures in the implementation of article 4.
19 JB9009-1999 "wire rope electric hoist safety procedures, inspection and maintenance of implementation of Article 5.
