The climbing frame hoist is widely used in the construction industry and the production of large oil tanks. The climbing frame electric hoist is also a kind of group crane electric hoist. The product has the advantages of compact structure, simple operation and convenient use, but its application field is relatively heavy. The ability requirements are high, so the overload protection device of the climbing frame hoist solves this problem to a large extent and greatly improves the work progress. Next, I will talk about the problem of the overload protection device. The overload protection device of the climbing frame hoist is a "self-protection system" mainly aimed at the overload use of the climbing frame hoist. Relevant data can show that overload protection devices are generally installed in "high-end" climbing frame hoists. It will be installed in the high-end climbing frame hoist, because it is a new skill in itself, and it is a modern product with high technology. With it, the grade of the entire climbing frame hoist will be improved. The same specification and quality of the same climbing frame hoist, the price with and without overload protection will be different. At the same time, the overload protection device of the climbing frame hoist is a special protection device for the operator, the hoist and the load. When the load is greater than the set value, the overload protection is automatically activated, and the hoist hoisting will automatically stop. This avoids a series of safety accidents caused by overloading.
