Abstract
A car for charging a coke oven battery with coal. This car carries a plurality of integral coal hoppers. A particular space frame construction is disclosed to support these hoppers, and because of this construction a significant savings in the weight of the car is realized. This space frame includes a pair of horizontally spaced lower front and rear parallel transverse beams and upper front and rear parallel transverse beams. Longitudinally extending beams connect both ends of the upper and lower front transverse beams with the corresponding rear transverse beams. The above described structure is mounted on four wheel housings by means of four truss structures. Two of these wheel housings are positioned slightly in front of the front transverse beams and two are mounted slightly behind the front transverse beams. Each of the front wheel housings is connected to the front transverse beams by means of one of the truss structures, and each of the rear wheel housings is connected to the rear transverse beams by one of the truss structures.
