A clamping device for clamping a rail or rail (12) on a support surface on a gantry crane comprises a cover (14) slidably mounted on a base (13), both secured by a bolt (15), said cover (14) comprising a body (18) and a nose (19) extending transversely outward from the body (18) along a nose axis. The body (18) of the base (13) and of the cover (14) comprises complementary opposing arcuate mating surfaces (21, 22) that enable rotational movement of the cover (14) relative to the base (13) about an axis P extending perpendicular to the nose axis. The base portion (13) and the cover portion (14) of the clamp are always engaged with each other regardless of the position of the nose portion of the clamp, so that the force exerted by the track on the nose portion of the clamp (10) can be directly exerted on the base portion of the clamp (10), thereby providing a clamp which is not liable to fail.
一种用于将轨道或导轨(12)夹紧在门式起重机上的支撑表面上的夹紧装置,包括滑动安装在一基部(13)上的一盖部(14),二者通过螺栓(15)固定,所述盖部(14)包括主体(18)和鼻部(19),所述鼻部(19)沿鼻部轴线从主体(18)横向向外延伸。所述基部(13)和所述盖部(14)的主体(18)包括互补相对的弧形配合表面(21,22),所述弧形配合表面(21,22)使得盖部(14)可相对于基部(13)围绕轴线P进行旋转运动,所述轴线P垂直于所述鼻部轴线延伸。无论所述夹具的鼻部的位置如何,所述夹具的所述基部(13)和所述盖部(14)始终互相接合,使得由轨道施加至所述夹具(10)的鼻部上的力直接可施加至所述夹具(10)的基部,从而提供不易发生故障的夹具。
