Electric chain hoist maintenance procedures 1. After a new installation or dismantling seized by the installation of electric hoist, the first test run should be empty several times. But not before the completion of the installation, should turn the power test. 2. Before normal use should be at 125% of rated load, lifting off the ground about 100 mm, 10 minutes of static load test and check whether it is normal. 3. Dynamic load test based on rated load weight, lift and move around for repeated testing, inspection after the test the mechanical transmission parts, electrical parts and the connecting portion is normal and reliable. 4. In the case of use, the absolute prohibition is not allowed in the environment and exceed the rated load and nominal closing per hour (120 times) for use under. 5. When the installation and maintenance, must be strictly checked limit device is flexible and reliable, when the limit was raised to the position of the hook, hook it to the shell away from the drum shell must be greater than 50mm (10t chain hoist, 16t, 20t must be greater than 120mm ). When the hook is lowered to limit positions in that chain hoist use, should ensure the safety rope on the drum circle, circle must be safe and effective in more than two laps. 6. Allowed to press two buttons to make pendant hoist movement in the opposite direction. 7. The total brake power must be opened after the work is completed, turn off the power. 8. Dhk manipulated by hand hoist chain hoist, the operator should fully understand the safety rules, non-oblique pull hanging crooked. 9. In use must be regularly checked by a specialist hoist personnel, failure to take timely measures to find and record them carefully. 10. Decline in the amount of electric hoist brake adjustment, should ensure that the rated load, the amount of brake slipped S≤V / 100 (V for load lifting stable within the next minute distance).
