Classification and manufacturing lifting beam, points to note when using
In lifting and moving operations, often encounter some large-scale precision equipment and long components, these devices and components in the lifting process is necessary to maintain balance, but also not to be lifting sling abrasions, and to hang in lifting during transport to deform minimized. To achieve the above requirements, the lifting operation in the use of crane lifting beams. Its main role is to increase the effective height of the crane lifting and hoisting expand the scope of the force to change the direction of the sling, the object being to avoid large horizontal pressure.
Based on years of research and development, production, sale, installation and maintenance experience, Huazhong Construction Machinery technical staffs make a few observations for hanging beam in the manufacture and use for the user:
Lifting beam is divided into a support pole hanging beams and hanging beams, pole lifting beam is mainly used for machinery and equipment Hoisting and lifting roof trusses, bridge, arch structure, such as slender and thin components, in addition, the use of leverage pole lifting beam, You can increase the range of the crane hoisting, namely to increase the turning radius of the crane. Especially when the subject of lifting height restrictions, such as the use of pole hanging beams can shorten the length of the sling, meet height requirements.
Hanging beam in the manufacture, use should be noted:
1, lifting beam design and manufacture of the safety factor cannot less than four times the rated weight. Hook on it, rigging and other response, said distribution is equal to the length of reliable connection, can be put into use after verification.
2. Before use, check the crane girder crane hooks and slings and connections are normal.
3. To maintain the level of the angle between the slings and lifting beam cannot be too small, in order to avoid excessive use of the horizontal component of deformation of the beam hanging. This angle should normally be between 45 ° -60 °. If the angle is too small, can shackle the crane hook on two ropes together and prevent its decoupling.
4. When the lifting beam cracks, permanent deformation, wear, corrosion serious should be immediately scrapped.
