Maintenance s kill tips for electric chain hoist

Electric chain fall hoist has the characteristics of advanced structure performance, small size, light weight, reliable performance and convenient operation. It is very convenient for lifting heavy objects, loading and unloading, repairing equipment, and lifting goods. It can also be installed on suspended I-beams and curves. Lift heavy objects on rails, cantilever guides and fixed lifting points. The maintenance skills of electric chain hoist are as follows:

The electric chain fall hoists should be tested with no loads several times before the first use      after installation. And it is important to remember that the electric  chain hoist should not be powered before the installation is completed.

The electric chain hoist  with chain falls should undergo a static load test of about 100 mm from      the ground at 125% of the rated load for 10 minutes before normal use, and      check whether it is normal.

The dynamic load test is to  perform repeated lifting and moving left and right tests with the rated load weight. After the test, check whether the mechanical transmission part, the electrical part and the connection part are normal and reliable.

During use, it is forbidden  to use it in an environment that is not allowed, and when it exceeds the  rated load and the rated number of closings per hour 120 times.

When adjusting the braking sliding amount of the electric chain hoist, it should be ensured that the braking sliding amount S≤V/100 under the rated load (V is the stable lifting distance within the next minute of the load).

The electric chain hoist  must be inspected regularly by special personnel during use, and measures should be taken in time when the fault is found, and carefully recorded.

It is not allowed to press two flashlight door buttons that make the electric chain hoist move in      opposite directions at the same time.

After the work is completed, the main switch of the power supply must be opened to cut off the power  supply.
