European-style crane electric hoist is generally equipped with the main beam. Since the electric hoist is not hoisted under the main beam as a whole, it is particularly difficult for the electric hoist equipment under the main beam. Assuming that the truck crane is used alone, it is difficult to equip the electric hoist. The difficulty of the equipment is that the center line, the lifting point line of the European crane and the center line of the main beam are all in a vertical plane. It is almost impossible for the truck crane to send the electric hoist to the required position, so there is a certain degree of difficulty in the equipment process.
The self-weight of the European standard bridge crane is much lighter than the traditional crane, and the transmission efficiency is high. The European standard bridge crane eliminates many of the above-mentioned transmission components, and selects better-performing materials to manufacture various key components, which greatly reduces the volume and weight of each arrangement, and then reduces the burden of the whole machine. The primary load-bearing component can naturally reduce the cross-section and weight. According to the above fundamental power formula, when the force is small, the power naturally decreases.
Users who have used domestic traditional cranes and European standard bridge cranes may find that the motor power of each arrangement of European standard bridge cranes is smaller than that of traditional cranes with the same tonnage and span. Although the power of the European standard bridge crane is small, it does not affect the operation. Assuming that the power of the traditional crane is configured according to the European power, it will show the shortcomings of the motor and even burn the motor.
When the electric hoist is equipped separately, the crane manufacturer generally uses two chain hoists to lift from both sides of the main beam. When the height of the main beam box is satisfied with the lifting space, two lifting straps can be used to form two lifting points around the main beam. Hang the Chain Hoist on two lifting points, and then hoist the electric hoist by hand. Since the two chain hoists are hoisted together, pay attention to the balance of the electric hoist during the hoisting process. After hoisting to the required height, the equipment and fixing can be carried out.
