The light oil handling crane pipe used in dispatching and dispatching operation of the oil depot still has some problems such as lax sealing, poor rotation and inconvenience to use even though it is continuously improved. In order to overcome the above shortcomings, improve working conditions and improve labor efficiency, our hospital through a more extensive investigation and study, drawing on domestic and foreign experience, repeated program comparison, and finally selected Dg100-I crane tube for the stereotypes. Figure 1 a for crane shape, Figure 1 b crane work status. After trial processing and preliminary use, we have received good results, reaching a reliable sealing performance, flexible rotation, easy to use and other requirements.
