Kirovets K-703МА-12-ОP

Bearing transporting vehicle for electric lines maintenance

Before quarry blasting it is necessary to remove bearings and electric lines used for energy supply of excavators, conveyors, pumps and other electric drive machinery. Taking into account that blasting is done regularly, at least once a week, it is necessary to remove bearings and electric lines into a safe place and do it as quickly as possible, and after the explosions to restore the electric lines for the machinery to function. The electric lines installation time is always sought to be decreased for the reduction of machines downtime. For that the technological machine is used – a bearing transporting vehicle. The machine crew consists of two people – a driver; an expert electrician.

The bearing transporting vehicle Kirovets K-703МА-12-ОP is intended for transporting and mounting of bearings with concrete and metal bases when building or reconstructing electric lines, by reinsertion of a dozer blade for operating platforms and approaches to the site planning as well. The bearings transportation is done assembled, with an assembled bearing in such a position, which allows
