Abstract
The crane is designed, manufactured in a box structure, balanced, sustainable. Materials used include steel sections, steel sheets commonly used. The link between the crane parts and details is the bolt or welded joint. Ensure that the welds are reliable, reliable and durable. Crane after manufacture, assembly finished are tested to meet the technical requirements set out. The main beam of the crane is designed in the form of a box and the letter I. It is the main force and the path of the electric palang. Depending on the lifting weights and the aperture of the crane, I match. Main girders in addition to the need to ensure durability also must ensure the hardness and elasticity, so the original beam was made available round the calculated. Rectangular box beams are made of 6-10mm thick steel plates. The two ends of the beam have a pivot linkage for mounting the crane spindle drive and are fitted with rubber elastic head to reduce the impact impulse when the crane moves to the end point of the runway. The connection between the main beam and the two side beams is achieved by means of high-strength angle weld. This article presents the structure of some types of crane and welding process for crane.
