1.light and small lifting equipment
Light and small lifting equipment is characterized by its handiness, compact structure and simple operation, and its operation range is mainly based on dot and wire. Light and small lifting equipment generally only has a lifting mechanism, it can only make heavy load for a single lifting movement. They are: Jack, pulley, hand (gas, electricity), hoist, winch, etc.. Electric hoists are often equipped with running cars and metal frames to enlarge the range of operations.
The characteristics of a bridge crane is that the weights suspended on the hook or other device can be vertically lifted or horizontally transported in space. Bridge crane includes lifting mechanism, big car and running mechanism. Depending on the coordination of these mechanisms, heavy weights can be lifted and transported in a certain cubic space. Bridge crane, Longmen crane, loading and unloading bridge, metallurgical bridge crane and cable crane belong to this kind.
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 hook to the wall of the minimum distance, headroom minimum, crane more close to the front of the work, higher lifting height, in fact, increased the effective working space of the existing plant. As the crane has light weight, small wheel pressure characteristics, the new plant space can be designed smaller, more complete functions. Smaller buildings mean significant savings in initial construction investment, as well as long-term heating, air-conditioning and other maintenance costs.
