Abstract
A maintenance and repair station for the maintenance and repair of charging cars of coke oven batteries comprises an elevator which has a cage with a trackway which forms a portion of the roof trackway over which the charging car operates and which may be shifted to a different elevation, for example, downwardly to position another trackway portion identical in length with the first in a position in which it forms a portion of the trackway over the coke oven battery. In this matter a charging car may be loaded onto the elevator and lowered to a repair station or raised to a different repair station while another track may be orientated in a place taken by the trackway portion of the elevator which also forms a portion of the trackway over the coke oven roof. Once the car has been removed, for example, downwardly into another station it may be maintained or repaired at such station while the trackway at the other level of the elevator is aligned with the charging car trackway on the roof so that other cars may be passed over the roof without interference.
