最严重的问题在于应用程序电力驱动的大型矿井提升机是电气控制。为了确保持续的成功运作一个电动提升机，为了向其提供控制系统，这个系统在任何时候都绝对可靠是必要的。设计必须是这样的，该仪器的所有部分即使经受最严重的，甚至是不合理的服务条件也不给予麻烦，不反复关注和维修。它应该被设计成这样的：不可能由于操作者的一个错误操作或错误的判断而损害控制器或机器的任何一个部分.
一般来说电器控制特别适用于通常位于偏远的供应中心，由不熟悉的人操作，而且作为一般规则与电力有关，并在拖延行动意味着巨大损失的矿业公司的矿井提升机。

ELECTRICAL CONTROL OF A LARGE MINE HOIST
BY H. W. CHENEY
The most serious problem encountered, in the application of electric drive to large mine hoists is that of electrical control, It is necessary, in order to secure continued successful operation of an electric hoist, to furnish a control system which is absolutely reliable at all times. The design must be such that all parts of the apparatus will withstand the most severe, and even unreason¬able, conditions of service without giving trouble and without repeated attention and repairs. It should be so designed that it is impossible for the operator to damage the controller or any part of the machinery by a wrong movement of the operating handle or by mis judgment of conditions.
This may be said of electrical control in general, but it applies with particular force to mine hoists, which are usually located remote from supply centers, are operated by men who are un¬familiar, as a general rule, with electricity, and where delays in operation mean tremendous losses to the mining companies.
