首先要知道悬挂葫芦的位置、上下吊钩、货物中心,必须处于同一直线才可以进行起吊的工作。在起吊开始之前一定要选择合适的悬挂点、或者适当的移动被起吊重物,一定要保证悬挂点,上、下吊钩,重物中心位于同一直线上,这样才能够确保在重物被起吊离开地面时不会出现严重的晃动;
First of all, we should know that the position of the hoist hoist, the upper and lower hooks and the cargo center must be in the same line before lifting. In the lifting start prior to the selection of suitable suspension points, or appropriate moves by lifting heavy objects, we must ensure that the suspension, the upper and lower hook, heavy center is located on the same line, so as to ensure that the weight is lifting off the ground does not appear serious shake;

然后就是匀速的上升才可以减少起吊过程中的晃动。飞鸽手扳葫芦是依靠扳动手柄的力实现重物起吊的,虽然随着重物重量的加大手扳力会适当的加大,但是它终究是手动起重葫芦再大的力也需要用人力去扳动。另外只有人力的扳动才可以掌控操作中保证货物可以匀速平稳的上升,减少了起吊中可能出现的晃动;
Then the constant rise can reduce the lifting process of shaking. Flying hand hoist is to rely on the handle the heavy lifting force, although with big traction force weight will increase, but it is a manual hoist and a large force is also necessary for human to move. In addition, only human pull can control the operation, to ensure that goods can rise steadily and steadily, reducing the lifting may occur in the rock;
红尘陌上的花开。似比相见又恨晚的聚散,相遇过早前方的路人,便会成为身后的过客。相识过晚倾城清风的颜美。便会与你擦肩,来不及仰望。说不出再见,从此山隔一河。却天涯此岸,回眸仰望已是曾经沧海,百花残月之冬。相遇有缘,离花漂过。景色的相遇正如那份。一直落在思念里的寒冬,无论冰川怎样刺骨。雪花怎样漂过,一颗执着的心。一直苦苦寻找。天暗未明微落的天空却被大雪覆盖,热血的少年。曾经的意志,却从未止步。从春天到寒冬。从寒冬到天荒,一直守护着这份。从未揭开的思念
