Shaking problem of climbing frame electric hoist

Many customers who use electric climbing frame hoist often encounter the situation of hoist shaking when working at height, and they will ask why the shaking degree of electric climbing frame electric hoist is different, and what is the problem related to the shaking degree of electric climbing frame electric hoist?
1. Reasons for inertia:
Generally occurs when the operation starts and stops. Climbing frame electric hoist belongs to a kind of group crane electric hoist. It has the characteristics of slow lifting speed, light body weight, high hardness of the machine parts, and low wear. The climbing frame electric hoist is also known as the "group hoist electric hoist". It retains the light and convenient characteristics of the chain hoist, and improves the lack of manual operation of the chain hoist. It combines the advantages of the electric hoist and the chain hoist. Use disc brake motor to do the work. For the same speed difference, the longer the drooping chain or rope, the greater the inertia and the greater the amplitude of jitter. When the rated load is the same, two electric hoist climbing frames with the same lifting speed can hang the same object. When the lifting height is 30m, the vibration amplitude is greater than the lifting height below 30m. For example, the lifting height is a climbing frame electric hoist.
2. External environmental reasons:
Under the influence of the external environment, the shaking is more obvious in the case of wind.
3. Carrying weight:
When two electric climbing hoists with the same technical specifications are carried on the same product model, that is, when the rated working load is the same, the lifting and speed are basically the same, and the height of the lifting enterprise is the same, when the same target object is lifted separately, the rope system or a chain is more The thinner climbing frame electric hoist, the greater the shaking rate. The climbing frame electric hoist is to try not to use messy ropes. The climbing frame electric hoist with the same equipment rated load, the same lifting height and the same level to increase the development speed, the shaking rate of the climbing frame electric hoist with the rope guide is higher than that of the climbing frame electric hoist with rope guide. More control. For the same climbing frame electric hoist, the weight of the object is different, and it also shakes differently. However, this is not easy to judge. Of course, this is inevitable, and the hoisting and hoisting of the climbing frame has always been an object. It can be used normally without overloading. So, this one is not counted.
The same climbing frame electric hoist, when the hoisted object is in a different shape design state, the shaking produced is also different. Generally speaking, electric climbing hoists can only lift objects without a single life, not people or animals. Animal research is also alive and alive. It is constantly struggling and moving in the lifting process, so that students will cause instability in production and lifting. Shaking will begin to occur. This kind of shaking has no law of development and cannot be directly controlled. It is easy to manage the occurrence of information overload, which is very important and dangerous. In relatively simple terms, hanging without life is smaller and safer than having life. Even if we have not realized the life of the object, the appearance is irregular, the hanging system or service is not tightly bound, the force is uneven, or it is liquid, it has a great influence on the shaking.
