Using miniature electric hoist should follow the following specification
In order to regulate electric rope hoist daily use and maintenance, to ensure the safe operation of electric hoist, stable, and must strictly enforce safety procedures relevant requirements.
One before using debug / checked
After a new installation or dismantling after the mini electric hoist, to be empty commissioning times. Not installed before the non-power operation.
2 installation or commissioning, check limit device is flexible and reliable, when hook up first limit position, the hook to the roll shell casings distance must be> 50mm lower limit position when the hook drops, should ensure that the roll wire rope safety circle, circle must be effective and safe in the more turns.
3 should be 125% of the rated load,hoist equipment lifting off the ground about 100mm, 10-minute static load test and check whether it is normal.
4 confirm the reliability of the brake status; adjust upper and lower limit stop module.
5 Check that the wedge is installed securely and reliably.
6 Check the wire rope is normal, if found bending, deformation, corrosion or wear serious, fracture extent exceeding the requirements, prohibited operation.
Two precautions in use
A miniature electric hoist shall hand manipulation, the manipulator should fully grasp their security procedures.
2 mini electric hoist in use by someone to check, paying particular attention wearing parts, and found fault,load chain immediately turn off the main power, to take timely measures.
3 is used, the absolute prohibition does not allow circumstances, and exceeds the rated load and nominal hourly closing times (120 times) of the cases.
4 in use, to maintain adequate oil and lubricating oil to ensure a clean and should not contain impurities and dirt.
5 prohibited by people standing on the lifting objects prohibited under strictly prohibited in the swing state of lifting, non-lifting of objects connected with the ground.
A miniature electric hoist does not work, you can not put heavy objects hanging in the air, to prevent parts produce permanent deformation.
2 mini electric hoist maintenance work must be carried out in a no-load condition.
3 Adjust the amount of electric hoist brake down,hoist and trolley you should ensure that the rated load, brake down the amount S ≤ V/100.
4 rope oiling, you should use a stiff brush or small wooden pieces by hand directly to the non-working rope oiled.
