According to the different load, climbing frame hoist is mostly divided into 5T, 7.5T, 10T, 15T, 20T, 25T and other different levels. In general engineering projects, the climbing frame is mainly lifted by 7.5T, and 5T also has a small number of engineering frames in use. . For example, the conventional large tonnage of 10 T or more is mainly used for the construction of storage tanks, that is, the load of the welding tank hoist. As a group hoist, in actual use, the actual weight of each machine is only about one-third of the rated body. Taking the 15T body as an example, the actual weight assigned to the body is only about 5-6T. At this time, it will Some people say that this will not cause a waste of resources. It is better to change a small tonnage. In fact, this idea is wrong. Why is it limited to one-third of the weight, mainly to ensure that the body can guarantee the rack in the event of an emergency? The body does not fall suddenly to prevent major accidents, which is also a safety concept in product design.Electric hoist
