The invention discloses an electric hoist bridge crane. The electric hoist bridge crane comprises a cross beam, a hoisting mechanism, a bracket and a rope ladder; the hoisting mechanism is positioned on the surface of the cross beam; the bracket is connected to one side of the hoisting mechanism; the rope ladder is connected to the interior of the bracket through a winding mechanism; the winding mechanism comprises a winding shaft rotationally installed in the support, and one end of the winding shaft is connected to the end of an output shaft of a winding motor through a coupler; and one end of the rope ladder is fixedly connected to the surface of the winding shaft. According to the electric hoist bridge crane, the rope ladder is installed on the hoisting mechanism through the bracket; the end of the rope ladder is fixed to the winding shaft; when an electric hoist breaks down and shuts down, the rope ladder can be lowered through rotation of the winding motor; maintenance personnel can climb to the position of the electric hoist to conduct maintenance and inspection conveniently; the safety of the maintenance personnel is improved; space limitation is avoided; and maintenance and inspection of the electric hoist are facilitated.

    本发明公开了一种电动葫芦桥式起重机,包括横梁、起重机构、支架和软梯;所述起重机构位于横梁的表面;所述支架连接于起重机构的一侧;所述软梯通过收卷机构连接于支架的内部;所述收卷机构包括转动安装于支架内部的收卷轴,所述收卷轴的一端通过联轴器连接于收卷电机的输出轴端部;所述软梯的一端固定连接于收卷轴的表面。本发明中在起重机构上通过支架安装软梯,软梯的端部固定在收卷轴上,在电动葫芦出现故障停机时,可以通过收卷电机转动,将软梯下放,便于维修人员爬至电动葫芦处进行维检,提高了维修人员的安全性,不受空间的限制,方便了电动葫芦的维检。
