Explosion-proof electric hoist is a kind of explosion-proof electric hoist. Explosion-proof electric hoist the exposed explosion-proof parts of the hoist are made of special non-spark materials, and the explosion-proof performance is safe and reliable. Products through the ministry of machinery industry explosion-proof electrical products quality supervision and inspection center Jiamusi sub-center explosion-proof performance testing, and issued explosion-proof certificate. It is not only small size, light weight, and compact structure, reliable braking, easy to use, high hardness, small wear. Explosion-proof electric hoist the exposed explosion-proof parts of the hoist are made of special non-spark materials, and the explosion-proof performance is safe and reliable. Products through the ministry of machinery industry explosion-proof electrical products quality supervision and inspection center Jiamusi sub-center explosion-proof performance testing, and issued explosion-proof certificate. It is widely used in all walks of life and brings convenience to our work. Explosion-proof electric hoist the exposed explosion-proof parts of the hoist are made of special non-spark materials, and the explosion-proof performance is safe and reliable. Products through the ministry of machinery industry explosion-proof electrical products quality supervision and inspection center Jiamusi sub-center explosion-proof performance testing, and issued explosion-proof certificate. So, to make it last longer, do it the right way:
1. For the new installation or disassembly inspection after the installation of explosion-proof electric hoist, the empty car should be tested for many times. However, before the installation is complete, be sure to turn on the power by all means.
two
In figure 3. Dynamic load test is the rated load weight, repeated lifting and moving around the test, after the test to check whether the mechanical transmission parts, electrical parts and connectors are normal and reliable.
4. In use, it is absolutely forbidden to use in the environment that is not allowed, exceeding the rated load and rated closing times per hour (120 times).
5. The flexibility and reliability of the limiter must be checked during installation, commissioning and maintenance. When the hook is in the upper limit position, the distance from the hook shell to the drum shell must be greater than 50mm (10T, 16T, and 20T must be greater than 120mm). When the hook drops to the lower limit, the wire rope safety ring on the drum should be guaranteed, and the effective safety ring should be more than 2 laps.
6. It is not allowed to press two torch door buttons at the same time to move the explosion-proof electric hoist in opposite direction.
7. After the work is finished, the main brake of the power supply must be opened and the power supply must be cut off.
Figure 8. It should be controlled by special personnel, and the operator should fully grasp the safety operation procedure. It is strictly prohibited to pull the inclined crane.
9 explosion-proof electric hoist in use, must be regularly checked by professionals, found fault should take measures in time, and carefully recorded.
When the explosion-proof electric hoist adjusts the brake slider, it should ensure that the brake slider SV /100 is under the rated load (V is the distance of stable rise under the load in one minute).
