Author's note: special equipment is not only an important guarantee for production and operation, but also a prominent risk of safety production, constituting the main contradiction factor of "physical defense", and it is necessary to carry out equipment quality standards and excellence activities on a regular basis, and strive to achieve "zero defects and zero failures" in equipment.
In our opinion, the biggest feature of lifting machinery is the four words "bulky, heavy, tall and large", which is the opinion and impression of most people.
That's right, it is precisely because of the characteristics of these four words that the requirements for the safety device of the lifting machinery are particularly important and critical. We must attach great importance to it, take it seriously, and not be careless, otherwise it will lead to safety risks and hidden dangers.
So, what are the requirements for the safety device of lifting machinery? The product description and operating procedures of each equipment are clearly and specifically stated. But in general, we should start from the following aspects to ensure that the safety device of lifting machinery is up to standard.
First of all, we say that the total power switch status of the crane should have an obvious signal indication in the driver's cab. This is particularly critical, as the so-called "machine control is not as good as human control", so the main power switch of the crane must always be under the control of the driver.
Secondly, when we talk about the lifting height limiter of the lifting mechanism, the function must be reliable and the effect is good.
Thirdly, the large and small car running mechanism should be equipped with a travel limiter, and it is reliable and effective. Of course, except for the electric hoist single girder, the trolley of the suspended crane and the manual crane running mechanism.
The fourth is the lifting weight limiter and torque limiter, which must be reliable and effective, and there is no room for mistakes.
Fifth, all kinds of safety devices should be safe, reliable and effective, the mechanisms should operate normally, the braking devices should be intact and effective, and the control system and electrical control system should work normally.
About the author: The number of keys is knocked quickly, a knock on the dawn, the text is not relaxed, and the hard work is longitudinal and horizontal. Don't let people praise the good color, just for this safety. Poor life's understanding, into thousands of words. May you open the book and ask for something, and cover the book to get something.
