到目前为止,提升设备还没有装上能够使较车司机知道他所进行的操作是否符合规定的速度图,或是否会发生事故危险的指示装置.目前在生产中所用的限速器(新克拉马托尔斯克斯大林工厂的机械限速器,顿巴斯列宁共产主义青年团十五周年工厂的ОСПМ-2型机械限速器,哈尔科夫电机制造厂的电气限速器),在结构上有许多缺点.新克拉马托尔斯克斯大林机械制造厂的机械限速器控制速度的范围狭小(额定速度的30—115%),本身的动作时间也长,而且会发生自发的闭合,以及与此相反,当由于主要执行工作装置失灵而发生事故时却又不能闭合,所以在工作中并不可靠.它的结构和整定工作也复杂.ΟСΠΜ-2型的机械限速器的结构也很复杂.
Up to now, the lifting equipment has not been fitted with a speedometer which allows the driver of the vehicle to know if the operation he is carrying is in compliance with the prescribed speed chart or whether there is a danger of an accident. The speed limiter currently used in production The mechanical governor at the Thorsk-Stalin plant, the ОСПМ-2 mechanical speed limiter at the 15th anniversary of the Donbass Lenin Communist Youth League, and the electrical speed limiter at Kharkiv's electrical plant) There are a number of drawbacks: the mechanical speed limiter of the New Kramatcholsk Stalin facility has a small range of speed control (30-115% of rated speed), its own operation time is long, spontaneous closing occurs, and On the contrary, it is not reliable in operation due to an accident that can not be closed due to malfunctioning of the main work implement, and its structure and setting work are also complicated. The structure of the Omega II-2 mechanical speed governor is also complicated .
