The carriage is used as an integrated part of a bucket wheel complex in surface mining. The carriage is a machine which ensures the discharge of a transported material from any place of a conveyor onto the stacker or a reloader, or into the stockpile (when the conveyor is located on the gantry of the raw materials warehouse). The belt of a conveyor is a load-carrying unit of the carriage, which is supported by roller supports and bends the deviating drums. When the reloading carriage operates, the conveyor s belt elevates from roller supports of a conveyor and runs on roller supports of a receiving part and deviating drums, after that it comes to the roller supports of a conveyor. A transported material falls from the main deviating drum into a receiving bunker of a discharging boom. Then, the transported material is reloaded from a discharging boom onto a stacker or is discharged into the stock pile at the warehouse of raw materials. Reloading self-propelled carriage is installed on the rails which are mounted on sleepers which are the basis of a belt conveyor or on the gantry. The design of the carriage ensures: decreasing the clearance between belt and rollers when the belt is not completely loaded in the transitional area conveyor-carriage ; possibility of running of belt under traverse and receiving part of carriage on roller supports of belt conveyor; possibility of slewing of a discharging boom of the carriage at the angle 90 0 degrees from a longitudinal axis of the belt conveyor; improved centering of drums (deviating and driving) because they are rubber lined and because they have bi-conic form of sidewalls; application of modern control and alarm devices; application of required protections; possibility of a lay-out of electric equipment and a socket of a cable input to the left and to the right sides along the direction of a material flow.

The stacker is designed as a part of bucket wheel complex for transporting the soft and medium hardness overburden rocks into the outer and inner dumps. It is used in open pit mining of minerals and construction materials, and for dumps formation while minerals processing. The stacker consists of supporting part which includes a base and shoe supports. The slewing platform with a walking mechanism and bottom superstructure is supported on the base with help of a roller wheel and a central trunnion. The assembly units are mounted on the slewing platform which forms the upper superstructure including a platform, an overhead crane, a slewing mechanism, a lubrication systems, ladders and platforms as well as an operator s cabin. Three main frameworks of the machine: a receiving console, a slewing platform and a piling platform carry the common conveyor, the drive with a tensioning system are located on a slewing platform. The device for picking up the spillage is located under a conveyor within the range of a slewing platform. Both these mechanisms (a conveyor and a picking up device) form a transporting system of a machine. Walking mechanism consists of two four-link mechanisms which are located on both sides of a slewing platform whereas a vertical link (a leg) of each mechanism leans on a shoe with the help of a sphere, its bottom transverse link (a cam) is connected via a shaft and an open transmission with a gear box, drives this mechanism into a movement. When the stacker is moving, it leans on two shoes which are located on both sides of the stacker and on a receiving console which is located at its end. Piling material is loaded onto the conveyor s bunker of a receiving console and falls from a discharge drum of a conveyor which is situated at the end of a discharge console. 104 LOAD-HAULAGE EQUIPMENT
