The invention provides a bridge crane beam which comprises two inverted-T-shaped supports. The two inverted-T-shaped supports are symmetrical front and back, empty grooves are formed in the outer surfaces of the front ends of the inverted-T-shaped supports, and clamping grooves are formed in the positions, close to the two sides, of the inner surfaces of the empty grooves. Limiting mechanisms aremovably connected to the interiors of the empty grooves and the two clamping grooves, and each limiting mechanism is composed of a rectangular plate shaped like an inverted Chinese character 'tu', twoclamping blocks, two limiting columns, two rectangular plates shaped like a Chinese character 'tu' and a hinge plate. A beam body and a machine body are convenient to assemble and disassemble, regular inspection and maintenance are facilitated, when the machine body is used outdoors, dust and burning sun can be shielded for a crane body in the machine body, the machine body is kept clean, moreover, rainwater is prevented from being accumulated on the surface of the beam body or in the machine body, damage is reduced, and finally the phenomenon that during hoisting of objects, due to the factthat a lifting rope is too thin and the lifting speed is too high, the objects shake and collide can be reduced.

    本发明提供了一种桥式起重机机梁,包括倒T形支架,所述倒T形支架的数量有两个,两个所述倒T形支架呈前后对称,且倒T形支架的前端外表面开设有空槽,所述空槽的内表面靠近两侧的位置均开设有卡槽,所述空槽和两个卡槽的内部活动连接有限定机构,且限定机构是由倒凹形矩形板、两个卡块、两个限定柱、两个凸形矩形板和合页板组成。本发明,首先方便梁体与机体的组装和拆分,便于定期检查和维修,且机体在户外使用时,可为其内部的起重机机体遮挡灰尘和烈阳,保持机体的清洁,再者,避免雨水积存梁体表面或者机体的内部,减少损坏,最后,能减少物品时在起吊时,因起吊绳过细和起吊速度移动过快,而造成物品会晃动和碰撞。
