Overwind height is an important parameter in the design of hoist. 提升機(jī)設(shè)計(jì)中，過(guò)卷高度是一重要參數(shù)。

If overwind height is too small,the safety of hoisting should be influenced. 過(guò)卷高度取值過(guò)小,影響提升的安全性;

This paper introduces the improving process of overwind and automatic speed reducting gear for mine hoist. 介紹了礦用提升絞車過(guò)卷及自動(dòng)減速裝置改進(jìn)的過(guò)程。

Here are expounded the basic principles of pointwise and enveloping ways to monitor speed to avoid serious overwind of a hoist reel and their correct usage. 闡述采用速度逐點(diǎn)監(jiān)視和包絡(luò)線監(jiān)視防止礦井提升機(jī)嚴(yán)重過(guò)卷的基本原理及應(yīng)用。

All kinds of hoisting overwind cushioning device and support cage device at home and abroad are compared , furthermore, multi-plate friction clutch is technical researched. 對(duì)國(guó)內(nèi)外各種型號(hào)的提升過(guò)卷緩沖裝置以及托罐裝置的緩沖器進(jìn)行了對(duì)比分析，并對(duì)多碟(凹盤(pán))摩擦緩沖制動(dòng)器作技術(shù)分析。
