The invention discloses a lifting type cantilever crane adopting rack transmission, and relates to the technical field of industrial components. A warning frame is installed at the bottom of a first steel wire rope at the lower end of the electric hoist, a stress plate is arranged in the warning frame, an object is hung through a hook at the bottom of the stress plate, the gravity of the object is the same as the pressing pressure of the stress plate in the hanging process, and a plurality of gravity detection balls are arranged at the bottom of the stress plate; when a suspended object exceeds a certain value, a shell on the outer side of the gravity detection ball is broken, the colored pigment flows out and is gathered in the transparent check ring, a worker can check whether the colored pigment leaks or not through naked eyes to judge whether the suspended object is overweight or not, the worker starts and stops the cantilever crane in time after the colored pigment leaks, protection on the cantilever crane is enhanced, and the working efficiency is improved. The quality and service life of the cantilever and the electric hoist are improved, and the use cost of the cantilever crane is reduced.

    本发明公开了一种采用齿条传动的可升降式悬臂吊,本发明涉及工业部件技术领域。该发明可以实现通过在电动葫芦下端的第一钢丝绳底部安装警示框,并在警示框内部设置受力板,通过受力板底部的挂钩对物件进行悬挂,在悬挂过程中物件的重力与受力板下压的压力相同,受力板底部设有多个重力检测球,在悬挂物件超过一定数值时重力检测球外侧的外壳破碎,使有色颜料流出并聚集在透明挡圈内部,工作人员可通过肉眼查看有色颜料是否泄露判断悬挂物件是否超重,在有色颜料泄露后工作人员及时启停悬臂吊,加强对悬臂吊的保护,提高悬臂和电动葫芦的质量和使用寿命,降低悬臂吊的使用成本。
