Грузоподъемные механизмы мостовых к

Грузоподъемные механизмы мостовых кранов (крюки, штанги, механизмы на комплексных кранах) должны иметь тройную изоляцию от моста крана, который перемещается по неизолированным от земли подкрановым путям — рельсы тележки изолируются от моста крана; механизмы, установленные на тележке, изолируются от ее корпуса, а крюк изолируется от обоймы. Каждая ступень изоляции должна иметь сопротивление не менее 1,5 МОм, измеренная переносным мегомметром напряжением 1000 В.
В процессе эксплуатации изоляцию очищают от пыли и грязи, а ее состояние периодически контролирует электрослужба.

Hoisting cranes (hooks, rods, mechanisms for integrated Cranach) must have a triple isolation from the bridge crane, which moves across the bare earth of podkranovym paths — are isolated from the trolley Rails bridge crane; mechanisms established on a trolley, segregated from her enclosure and hook is isolated from the stator. Each step must have insulation resistance is not less than 1.5 Mω measured portable megommetrom voltage 1000 v.During the operation the insulation clear of a dust and a dirt, and its state periodically monitors elektrosluzhba.

Hoisting mechanisms traveling cranes (hooks, rods, mechanisms of complex taps) must have a triple isolation from the bridge crane that moves on the ground bare crane railway - trolley rails are isolated from the bridge crane; mechanisms mounted on the carriage, is isolated from its housing and is isolated from the hook holder. Each step of the insulation resistance should be not less than 1.5 megohms, measured voltage portable Megger 1000 V.
In the operation of the insulation cleaned of dust and dirt, and its state periodically monitors elektrosluzhba.

paper mechanisms of overhead cranes (hooks, weights, mechanisms for integrated crane) should have a triple insulation from a bridge crane which travels on неизолированным from earth подкрановым waterways - track trolley separated from bridge crane; mechanisms installed on the cart, separated from its casing, and the hook is isolated from practice. each step of the isolation resistance should be not less than 1.5, iom, as measured by the portable мегомметром voltage of 1000.in the process of the exploitation of the isolation of clean of dust and dirt, and its status periodically monitored электрослужба.
