The invention discloses a safe and reliable crane, and relates to the technical field of cranes. The safe and reliable crane specifically comprises a column body and a second rotating shaft, a mounting flange is fixed to the outer wall of the column body, a first rotating shaft is arranged at the upper end of the column body, and a connecting column is arranged at the upper end of the first rotating shaft. The safe and reliable crane for communication is provided with an extendable rod, the extendable rod fixed to the outer wall of a shell can rotate and extend through threads, and therefore a fixing piece at the tail end of the extendable rod tightens and fixes an auxiliary arm, so that a stable triangular structure is formed among the extendable rod, the auxiliary arm and the connecting column, the bearing performance of the auxiliary arm and a main arm is greatly improved, it is guaranteed that the crane is not prone to being broken and deformed when lifting heavy goods, and the safety of the crane is improved; and the fixing piece can be adjusted at all angles and in all directions so that the fixing piece can be fixed to the auxiliary arm in a more attached mode, the shell and the second rotating shaft ensure that the extendable rod can smoothly rotate along with the first rotating shaft and does not interfere with each other, and the structure is more reasonable and reliable.
本发明公开了一种安全可靠型起重机,涉及起重机技术领域,具体为柱体和第二转轴,所述柱体的外壁固定有安装法兰,且柱体的上端设置有第一转轴,所述第一转轴的上端安置有连接柱。该通讯用安全可靠型起重机设置有伸缩杆,外壳外壁固定的伸缩杆可通过螺纹进行旋转延长,从而使其末端的固定件对副臂进行收紧固定,从而使伸缩杆、副臂以及连接柱之间形成稳定的三角结构,大大提升了副臂及主臂的承重性能,保证其吊运大重量货物时不易发生折断变形,提高了起重机的安全性,固定件可进行各角度及方向的调节,以便其更加贴合的与副臂进行固定,外壳与第二转轴保证了伸缩杆可随着第一转轴顺利进行旋转,相互之间互不干扰,结构更为合理可靠。
