Yudiao Group Electric Hoists in Daqing Oilfiled Tank Project

　　In New oil tank construction ,it can reduce labor strength and improve efficiency if use electric hoist instead of chain blocks.However,the focus factor of improve efficiency and safety is how to avoid overload in electric hoist operation,which needs people to pay utmost attention .

　　First,need calculate tanks’ correct weight.General the total rated of electric hoist is above 1.3 to 1.5 times more than tank’s weight.After confirming the electric hoist quantity, need calculate and decide the distance between lifting points accurate.The distance must be equal and evenly distributed.As required in the construction process for the first time less skylights, so the lifting points to as little as possible for the first time. In addition that, consider the balance after lifting point set to keep the lifting point of single spacing is equal, as far as possible for welding jar of electric hoist is running. According to the previous construction experience, lifting point for the first time for the selected welding jar of electric hoist sets of half, the second after the hoisting construction, namely before lifting the third layer to fill in the rest of all lifting point pillar in time, put up a complete set of welding can of electric hoist, all in the third layer of hoisting operation. In the course of promotion, the heavy industry professional will be responsible for the on-site command.
