The unloading platform consists of sections of different lengths, which ensures uniformity of conveyor loading: coke portions coming off the unloading platform are placed on the conveyor belt in a certain order. Several unloading platforms are installed along the inclined platform (according to the number of unloading zones on the inclined platform) and each such platform has its own drive and crank mechanism. In this way it becomes possible to control the ramp operation: to accelerate the unloading of the inclined platform or to exclude some parts of the ramp from operation without stopping the unloading.
The coke ramp is a sloping platform lined with cast-iron (working on average 1 year) or heat-resistant stone slabs (working on average 10 years). The resistance to coke movement on the ramp is sharply reduced when lined with heat-resistant stone castings compared to lining with other materials - heat-resistant cast iron, fireclay bricks or ceramic materials.
The inclination of the ramp is about 28°. The length of the ramp allows to place coke from 4 - 5 furnaces on it. The coke is lowered from the ramp by lifting the sector gates. From the ramp coke gets to the belt or screw conveyor (the bottom of which is also lined with wear-resistant stone slabs), and then through the transfer station to the roller screen of coke sorting.
