Inspection. Organized by the unit led the first device security management challenges, jointly with relevant departments, in addition to monthly inspection items, the main technical parameters of the lifting machinery testing, reliability testing, heavy lifting equipment, by detection equipment, lifting machinery, wear, weld metal structure test testing working mechanism moving parts through the test safety devices and components, running the technical condition of the lifting equipment to evaluate and arrange repair, alteration, update. When people often use the crane in equipment handling process, use the crane operator, crane hoists shall be the oblique oblique, that hoisting rope hanging objects through the center of gravity and perpendicular, that allowed the oblique oblique hanging a lot of people In this regard some questions, why not oblique crane hanging it? 1, it is possible to overload the crane oblique hanging on the assumption that weight lifting objects from the floor for the Q, vertical lifting, lifting handling equipment, wire rope tension S as long as equal to or slightly greater than Q Q, the weight can be off the ground, but if the oblique, wire rope and on the ground at an angle to the vertical. According to mechanics, acting on the rope pull S, so that the object can be decomposed into a vertical upward force P and horizontal movement The force F, make the object hanging from the ground, Liaocheng lifting equipment, P Q. At the same time at least equal to F with the angle increases. In other words, the larger the angle oblique hanging when, in the same hanging When the body weight of the rope the force is greater. Therefore, if a heavy load full vertical lifting, then there must overload oblique hanging, rope and even pulled off the accident occur. 2, a crane hanging oblique produce inertial force , resulting endanger those around Further, oblique hanging horizontal component F, when the weight is affected before leaving to friction in an instant from the ground, will object to the vertical center of swing, lifting equipment installation, which it is possible and hang hanging personnel, workers or other objects around the collisions caused by an accident. In short, if oblique hanging, not only will cause overload pull off the rope, and make heavy swing jostling objects and people, causing personal and large equipment lifting equipment accidents, Shandong Lu lifting (online consultation), lifting equipment provided by the Shandong Liaocheng in Shandong mechanical equipment installation Limited. Shandong Lu Machinery Installation Co., Ltd. (www.sdlzqz.com) Shandong Jinan, industrial maintenance, installation of leaders, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
