A telescopic fork (9) extendable between an extended operating state and a retracted operating state, the telescopic fork comprising: a base (10) extending in a longitudinal direction and having an upper raceway (38) and a lower raceway (39); an intermediate slide (20) extending telescopically in a longitudinal direction with respect to the base (10) and having a plurality of rollers (50) supported by the intermediate slide (20) and rotatably mounted about a horizontal axis (50a); and a distal slider (30) telescopically extendable in the longitudinal direction relative to the intermediate slider (20) and having an upper raceway (43) and a lower raceway (44). The rollers (50) of the intermediate slide (20) are simultaneously in rolling contact and engagement with the raceways (38, 39) of the base (10) and the raceways (43, 44) of the distal slide (30) during at least part of the stroke of the fork (9) in which the fork approaches the retracted operating state.
一种伸缩式货叉(9),其可在伸展操作状态和缩回操作状态之间伸展,所述伸缩式货叉包括:基座(10),其在纵向上延伸并具有上部滚道(38)和下部滚道(39);中间滑动件(20),其相对于基座(10)在纵向方向上可伸缩地伸展并具有多个滚子(50),多个滚子由中间滑动件(20)支撑并绕水平轴线(50a)可旋转地安装;以及远侧滑动件(30),其相对于中间滑动件(20)在纵向方向上可伸缩地伸展并具有上部滚道(43)和下部滚道(44)。在货叉(9)的行程的至少一部分期间,中间滑动件(20)的滚子(50)与基座(10)的滚道(38,39)和远侧滑动件(30)的滚道(43,44)同时滚动地接触并接合,所述行程的至少一部分中,货叉接近缩回操作状态。
