随着建筑业飞速发展,塔机在建筑工地运用的越来越多,随之而来的机械伤害事故也在逐渐增加。其中吊钩坠落事故在施工现场就时有发生,轻则造成财物损坏,重则造成人员伤亡。本文提出一种吊载悬停控制技术,在塔机安全使用中多了一重保护。1塔机吊钩防坠落目前技术状况1.1目前技术状况塔机产品通常在起升机构总成上安装有刹车制动装置。方式一是在传动系中安装机械制动装置,即当起升机构做上升或下降动作时,制动装置自动打
With the rapid development of the construction industry, more and more tower cranes are being used in construction sites and the consequent mechanical injury accidents are gradually increasing. Hook crashes accident occurred at the construction site from time to time, ranging from property damage, while causing heavy casualties. This paper presents a hanging suspension control technology, the tower crane in the safe use of a more weight protection. 1 tower cramp anti-falling the current state of the art 1.1 current technical conditions tower crane products are usually installed in the brake assembly brake assembly. One way is to install a mechanical brake device in the transmission, that is, when the lifting mechanism to do the rising or falling action, the brake automatically hit
