目前液压货梯http://www.jnliqiao.com/附加起重装置存在的隐患在检验中我们发现，配备附加起重装置的液压货梯，有很多项目不符合相关规定。

1、没有起重作业性能曲线，液压货梯的起重能力随幅度的变化而不同，起重作业性能曲线可以指导作业人员控制起重机的安全起重量。
No lifting operation performance curve, hydraulic freight elevator lifting capacity varies with different amplitude, the lifting operation performance curve can guide from the weight of the crane operator to control security.

2、未设置液压货梯和起重作业的联锁保护装置，可能厂家认为用户不会同时使用，就没有设置互锁功能，应该从根本上消除这种可能引发事故的隐患。
Hydraulic Hoists and lifting operations interlock protection device is not provided, may manufacturers that users do not use, there is no set interlock function should eliminate the risk that an accident could occur fundamentally.

3、液压货梯缺少必要的安全装置，液压货梯附加的起重装置缺少很多安全装置，如未装设起升高度限位器、起重量指示器、幅度指示器等。
Hydraulic freight elevators lack the necessary safety devices, hydraulic freight elevator lifting device lacks many additional safety devices, if not installed lifting height limiter, from the weight indicator, amplitude indicators.

4、液压货梯http://www.jnliqiao.com/厂家在随机的《使用说明书》中对起重装置的使用没有说明，造成有的用户缺乏基本的常识。
Hydraulic freight elevator manufacturers in the random "Operating Instructions" in the use of the lifting device is not illustrated, causing some users lack basic common sense.
