目前液壓貨梯http://www.manetech.cn/附加起重裝置存在的隱患在檢驗中我們發現，配備附加起重裝置的液壓貨梯，有很多項目不符合相關規定。

1、沒有起重作業性能曲線，液壓貨梯的起重能力隨幅度的變化而不同，起重作業性能曲線可以指導作業人員控制起重機的安全起重量。
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、未設置液壓貨梯和起重作業的聯鎖保護裝置，可能廠家認為用戶不會同時使用，就沒有設置互鎖功能，應該從根本上消除這種可能引發事故的隱患。
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、液壓貨梯缺少必要的安全裝置，液壓貨梯附加的起重裝置缺少很多安全裝置，如未裝設起升高度限位器、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、液壓貨梯http://www.manetech.cn/廠家在隨機的《使用說明書》中對起重裝置的使用沒有說明，造成有的用戶缺乏基本的常識。
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.
