Light and small lifting equipment
Light and small lifting equipment is characterized by portability, compact structure and simple operation, and the projection of the working range is mainly based on dot and line. Light and small lifting equipment generally has only one lifting mechanism, it can only make the weight of a single lifting movement. There are jacks, pulleys, hand (pneumatic, electric) hoists, winches, etc.. Electric hoists are often equipped with running cars and metal frames to expand the scope of operations.
The characteristic of bridge crane is that the weight hanging on the hook or other device can realize vertical lifting or horizontal movement in space. The bridge crane includes: lifting mechanism, large car, running mechanism. Depending on the coordination action of these mechanisms, the heavy objects can be lifted and transported in a certain cubic space. Bridge crane, Longmen crane, loading and unloading bridge, metallurgical bridge crane, cable crane and so on belong to this category.
The bridge crane has the advantages of light weight, compact structure, low energy consumption, set up a car on the bridge and hoisting mechanism, the car can run the cart before and after operation, and other institutions, to achieve material handling of objects in three-dimensional space, European crane unique design, small size, light weight, small pressure characteristics round. Compared with the traditional crane, the minimum distance between the hook and the wall is the minimum, the clearance height is the lowest, the crane can be closer to the front work, the lifting height is higher, and the actual work space of the existing factory is increased. Because the crane has the characteristics of light weight and small wheel pressure, the new workshop space can be designed smaller and more functional. Smaller buildings mean that initial investment in construction, as well as long-term heating, air conditioning and other maintenance costs, can save a considerable amount of money.
