Jack is one of the repair work of the most commonly used tools, compact, easy to use. However, if used improperly can cause the body's heavy slump and injured accident. Therefore, when used to pay attention to the following issues: (1) jack to use to pad the bottom flat, tough. No oil in the wood to expand the bearing surface, and ensure safety. Can not be replaced with iron wood, to prevent sliding. For a smooth (2) lifting, a little heavy after starting to check whether the abnormal conditions, such as no abnormal situation to continue up top. Not any longer handle or excessive action. (3) do not overload, high. When the sleeve appears red industrial lifting equipment, indicates that the rated lifting height should stop. (4) when several simultaneous operation of mechanical equipment lifting jacks, to have someone directing factory lifting equipment, so lifting or falling simultaneously. To support between two adjacent jack wood, ensure the interval to prevent sliding. (5) should always pay attention to the sealing portion of the pipe joint portion when using the jack, you must ensure that it is safe and reliable. (6) does not apply to establishments jack acid, alkali or corrosive gases. In some large equipment during transport, crane hoisting equipment handling process is inevitable and for hoisting equipment handling problems, we have the following requirements: First, the indigenous construction method using a rolling mobile handling equipment, roll bar thickness to be consistent lifting equipment, care should be higher than the annual long row width 50cm, non-roll bar filled with gloves. handling car piping slope not greater than 20 °, raceway erection to be smooth, solid, joints staggered, scrolling speed is not too fast , use a slip rope if necessary. Second, during the installation process, such as problem should take timely measures to deal with and then continue lifting. Third, the use of large derrick hoisting tower equipment, multiple hoist joint operation, you must request the roughly the same speed hoist winch, to ensure that each point of the tower crane on the force generally tends to be uniform to avoid discontinuity tower uniform deformation. Fourth, when using rotary method or the method of lifting tower toppled tank, the bottom of the tower wrist hinge installation must have the ability to resist the process of lifting the level of thrust produced, about the process of lifting the tower slipped the rope must be firm, turning in place when the tower height to slowly fall into the foundation, to avoid accidents and deformation Fifth, the frame body or when installing the device, its strength and stability to achieve the requirements of the building installation conditions. After installation positioning requirements according to drawings fastened or welded connection, designed to meet the strength requirements and After having stability to decoupling, or to temporarily fixed equipment lifting handling, lifting equipment, Weihai, Shandong company of choice offered by Shandong Lu mechanical equipment installation Limited.
