Some workshops did not consider the space of the double girder crane in the design. Therefore, after the double girder crane is installed, the hoisting height cannot satisfy the hoisting requirements. So how to choose a double girder crane in this situation?
Double beam crane is a kind of special equipment. Pay attention to some matters when using it to avoid unnecessary damage. The operator of the double-beam crane in the workshop conducts a brief check on the equipment every day, including whether the bolts are loose and whether there is oil leakage. When the double-beam crane in the workshop cannot be used normally, it should be shut down for maintenance immediately, and diseased operations are prohibited.
Generally, the electric hoist of a double-beam crane is suspended under the main beam with a height distance of 1.5 meters. If the European-style double beam low headroom crane is used, the lifting height can be increased by 1m.
Crane repairs should be carried out by crane manufacturers with double beam repair qualifications. It is forbidden for non-repair personnel to repair the double beam crane equipment in the workshop under any potentially dangerous conditions. The repaired double girder crane should be tested before use, and it can be put into normal use only after it is qualified. The double-girder crane that fails the test shall be repaired and re-accepted after inspection. Cranes that have not been inspected shall not be put into operation.
The low headroom European-style double beam crane is light in weight, small in structure, and low in energy consumption, which can effectively increase the use of space. There are trolleys and lifting organizations on the bridge, the trolleys can run back and forth, and the trolleys can move in a three-dimensional space. The design concept of the European-style double girder crane has the characteristics of small size, light weight and low wheel pressure.
Cranes in operation should be inspected and checked regularly. The wire rope is aging, damaged, the hook insurance is damaged, and the performance of the equipment is unstable and punctual, it should be repaired and replaced in time. Equipment that does not meet the operating requirements shall be returned. When two double-beam cranes are used to lift objects together, the extra load of the cranes should be reasonably distributed, command in a unified manner, and the lifting should be carried out smoothly and gradually. It is forbidden to overload double-beam cranes.
Compared with the traditional crane, the limit distance of the hook wall is small and the headroom is low. The European-style double beam crane can work closer to the front and increase the height higher, which actually adds useful working space in the existing workshop. Because the crane has the characteristics of light weight and low wheel pressure, the space of the new plant can be designed to be smaller and more complete.
During the normal hoisting process of the double-beam crane in the workshop, no more than one person is allowed to command, but the urgent parking signal of anyone should be stopped immediately. , When stopping the operation, do not lift the object into the air. During the operation, when someone is within the range of a moving or falling object, a warning signal should be sent. Do not pierce heavy objects with your head. The elevator must not be too high above the ground.
