The invention relates to the technical field of crane frames, in particular to a bridge crane frame which comprises bases, a hydraulic device, a cross beam and a lifting machine, an electric guide rail is fixedly connected to the middle position of the top ends of the bases, a first sliding groove is fixedly connected to one side of the electric guide rail, and a second sliding groove is fixedly connected to one side of the electric guide rail. The two bases are arranged at the bottom end of the crane frame, the electric guide rail is arranged at the top ends of the bases, meanwhile, the electric guide rail is provided with the first sliding groove and the second sliding groove, and a sliding table is slidably connected to the top end of the electric guide rail. When the sliding table drives the crane frame above the sliding table to move on the electric guide rail on the bases, a first guide wheel and a second guide wheel in the sliding table can slide on the first sliding groove and the second sliding groove in the electric guide rail, so that kinetic energy friction between the sliding table and the electric guide rail is reduced when the sliding table slides on the electric guide rail.
本发明涉及起重机架技术领域,具体为一种桥式起重机架,包括底座、液压装置、横梁和起吊机,所述底座顶端的中间位置固定连接有电动导轨,所述电动导轨的一侧固定连接有第一滑槽,所述电动导轨的一侧固定连接有第二滑槽。本发明通过在起重机架底端设置两个底座,底座的顶端设置有电动导轨,同时在电动导轨上设置有第一滑槽与第二滑槽两组滑轨,并在电动导轨的顶端滑动连接有滑动台,当滑动台带动上方的起重机架在底座上的电动导轨上移动时,滑动台内部的第一导轮与第二导轮可以在电动导轨上的第一滑槽与第二滑槽上滑动,使滑动台在电动导轨上滑动时,减少滑动台与电动导轨之间的动能摩擦。
