The large-sized crane which has lightning reduction function

摘要

Abstract Topic Resonating to radio wave for broadcast, in the high frequency high tension which it occursAt the same time permanent, to be able make the electric shock lighten which depends effectivelyOffering the large-sized crane which has the lightning reduction function of ru simple structureIt does. Solutions The electric shock which is provided in crane 1 for container conveyanceAs for reduction device 19, sheave of bottom side of wire 10a for hoistFrom 11 in suspender component 14 in multiple places of ru electric conduction type installationThe re it is it possesses multiple insulating components 11b, 13a and 20aSo, operation to suspender component 14 the high frequency voltage in each insulating componentTo be eased lower, as for sneak current magnetism of the high frequency magnetic material makeIt is absorbed with component 17a. Therefore, credit for container conveyanceAs for n 1 with lightning reduction device 19 suspender component 14 and konStabilizing regardless of to the position of tena, 15 lighten electric shockTo be possible, at the same time permanent, operation to suspender component 14 effectivelyIt can make the electric shock lighten due to high frequency voltage.
