With the uprising movement of Chinese railways and progress of electric railroad, the small tonnage full hydraulic railway crane becomes more urgently needed for development with characteristics of fast speed self-propelled running and high speed in train formation, hence, the high level requirement is resulted in terms of train formation and self-propelled running speed of railway crane. For 20t universal railway crane, features such as running with the load and weight lifting due to high hauling capacity are required besides hook lifting, bucket grabbing and magnetic panel lifting.

随着我国铁路事业的不断壮大，电气化铁路的发展，开发小吨位的自力走行速度快、回送速度高，能满足电气化线路的立杆作业的全液压铁路起重机迫在眉睫，对铁路起重机的回送和自力走行速度有了更高的要求。20t多功能铁路起重机，即具有吊钩、抓斗、磁盘吊3种功能外，还具有一定带载走行以及因牵引能力大也可作为吊车机使用。

The influences of traction angle , coefficients of friction and helix angle on the flow rate of solids were discussed.

理论上证明了这两种情况下的固体输送机理与外螺杆的情况相同，均建立在固体摩擦输送机理基础之上；讨论了牵引角、摩擦因数和螺纹升角对上述三种情况固体输送流率的影响。

Generate considerable thrust. The catapult officer releases the pistons, the force causes the holdbacks to release, and theforward.

弹射指挥员释放活塞后，巨大的拉力将牵引释放杆拉断，巨大的蒸汽压力猛烈地撞击着滑块拖动着飞机向前冲去。

Mechanical transmission, simple operation, traction big, fast, easy maintenance, construction is not only line of defense in Ligan, Tajikistan, and bear the fine line equipment, but also as a long-held or tension line the ideal machine.

机械传动、操作简单、牵引力大、速度快，维修方便，不但是放线施工中立杆、塔、紧线的优良设备，更是作为630导线以下牵引或张力放线的理想机具。

When the JBD, towbar and holdbackare all in position, and all the final checks have been made, the catapult officer(also known as the "shooter") gets the catapults ready from the catapult control pod,a small, encased control station with a transparent dome that protrudes above theflight deck.

在竖好喷气偏流挡板，固定好挂钩和牵引释放杆并完成最终检查之后，这时飞机弹射器操作指挥员，已经在凸出于飞行甲板且密闭的圆形透明控制台内做好了随时弹射的准备。

The rear suspension uses the Cyclone 12 Micro Shock Absorber combined with an adjustable fibreglass T-bar to give the Cyclone 12 unreal rear traction in the corners and off the starting line.

后悬挂使用气旋12微减振器结合可调吨玻璃纤维杆，使气旋12虚幻的后方牵引，在弯道和小康的起跑线上。
