The invention belongs to the field of travelling cranes, and particularly relates to a safe travelling crane which comprises guide rails, travelling mechanisms A, tripods, a cross beam, travelling mechanisms B, a hoisting mechanism, a traction mechanism A and a traction mechanism B. The cross beam is installed between the two tripods in a suspended mode, and the bottoms of the tripods are provided with the travelling mechanisms A matched with the guide rails in a one-to-one correspondence mode. And each guide rail is matched with two traction mechanisms B which form front-back balanced traction on the corresponding tripod to prevent the travelling crane with higher moving speed from toppling over due to movement inertia. The four traction mechanisms B form front-back balance traction on the two tripods at the two ends of the cross beam from front to back, so that the safety accident that the traveling crane topples over due to inertia when braking under the condition that the traveling speed is high is avoided, and the traveling crane can hoist and transfer goods at a high speed; the cargo hoisting and transferring efficiency of the crane is improved.
本发明属于行车领域,尤其涉及一种安全行车,它包括导轨、行走机构A、三角架、横梁、行走机构B、起吊机构、牵拉机构A、牵拉机构B,其中横梁悬空安装于两个底部均具有与导轨一一对应配合的行走机构A的三角架之间,每个导轨上均配合有两个通过对相应三角架形成前后平衡牵拉来防止运动速度较快的行车因运动惯性而发生倾倒的牵拉机构B。本发明通过四个牵拉机构B从前后对横梁两端的两个三脚架形成前后平衡牵拉,使得行车在其行走速度较快的情况下进行制动时不会发生因惯性而倾倒的安全事故,从而保证行车可以以较快的速度进行货物的吊装转运,提高行车吊装转运货物的效率。
