In lifting operations, the heavy bundle is a technology live, if a part of a little mistake, it will be possible crane accidents occur, in order to ensure safe lifting process, when lifting heavy objects with lashing should pay particular attention to the following is Select lashing sling should be noted that a few key points. First, the lashing point to be at the top of the center of gravity of lifting objects, and a little above the center of gravity of the lifting of direct elections; secondly, the overall strength to the main lifting objects that lift objects can not cross; In addition to the above two points, but also pay attention to lashing point local, not instability, not torn, torn. Choose a good lashing point not only to avoid unnecessary friction, classification sling, and greatly extend the life sling, but also improve the security of the entire lifting operation of flat, round sling, rigging sets the following occurs When one of Dyneema sling, should stop using the 1, the body is cut, badly bruised, with a share of loose, when the partial rupture, should be scrapped; 2, the surface of serious wear and tear, lifting belt use standard lifting with abnormal deformation fluff, When Weifang loading zone, lifting the original width of wear reach 1/10, should be scrapped; 3, synthetic fibers soften or aging (yellowing), surface roughness, synthetic peeling, elastic smaller, strength weakened, should be scrapped; 4, lifting belt moldy. Acid burns. Hot melt or char the surface more loose, when corrosion, should be scrapped; 5 sets of rigging metal severe bruising, resulting in deformation of the use; 6, sets of rigging seriously corroded metal strength. Use standard sling, lifting belt supply (certification), Weifang sling from Hebei chen sling Manufacturing Limited. Hebei chen sling Manufacturing Co., Ltd.
