Train formations for removal of litter

SZ-160-4, SZ-240-6

  Are designed for mechanized accumulation, transportation to places of dumping and mechanized unloading of litter, foul ballast and other bulk materials while performing operations coupled with cleaning machines, ballast cleaning machines and complexes in maintenance and all kinds of railway track repair.
  The main train formation for removal of litter SZ-240-6 consists of six multipurpose gondola cars based on the four-axle flat car of model 13-401 and one rear-end car based on the same flat car to control the train and unload the accumulated material.
  An inclined frame with a body (edges preventing materials from spillage) is fixed on the flat car of every multipurpose gondola car and serves as the base for the accumulation conveyor manufactured of a closed-type rubber-fabric band 2.2 m in width . The band is strengthened with profiling plates rigidly connected with the links of  two branches of the haulage chain resting on the rollers of the guiding inclined frame and engaged with the sprockets of the driving shaft and the tension shaft. Every multipurpose gondola car is equipped with a double-speed electric drive of the  accumulation conveyor, a switch box with electric equipment and a trunk line with a power electric cable and a control  electric cable.
   The slewing conveyor and the intermediate conveyor with a band 1.2 m in width, the hydroelectric power station, the control cab and the system of power supply are mounted on the flat car of the rear-end car. Each conveyor is equipped with two motorized conveyor drums  on the driving shaft and on the tension shaft to provide the guaranteed output and operational reliability.
