6.3. Technology of maneuvers at the hump
Excess driving force must be extinguished by braking the cars at special braking positions (BP). On high-power and high-power slides, three brake positions are equipped (Fig. 6.3.1). Braking of cars rolling down a hill on non-mechanized hills is carried out using manual brake shoes. Special forks are used to place shoes under the wheels of moving cars.
Rice. 6.3.1
The technology for sorting cars from the hill is as follows. All trains subject to disbandment arrive at the reception park, where the trains are prepared for disbandment. During the process of disbanding from the hill, half-flights are performed sequentially; arrival of the locomotive to the train, pushing the train onto the hill, breaking up the train, sorting the cars and unloading the cuts. When a hump electric locomotive arrives, from the hump of the hump it follows the free path of the reception park to the locomotive dead end, and from the dead end - back to the train in the reception park. After the locomotive is coupled, the train is pushed up to the hump of the hump. In front of the hump, the roller coaster uncouples the train into uncouplers, which are then rolled onto the path of the sorting yard for its intended purpose.
An uncouple is a separate car or a group of cars connected to each other, following sorting to one destination route.
Along the descent part of the hill, the trailers move at different speeds, depending on their mass. When the set speed increases, as well as in order to create intervals between the releases (to change the arrows), the releases are braked at the braking positions. As a result, cars on the sorting tracks can either follow until they engage the cars standing there, or stop at a distance from one another. There is a need to couple these cars and move them deeper into the park in order to clear the tracks for the dissolution of the next trains, i.e., to perform the unloading operation. According to the experience of operating slides, settling is not carried out after each dissolution, but after the dissolution of 3-4 trains.
The process of disbanding a train at a hump can be represented in the form of a technological schedule for the hump (Fig. 6.3.2).

Rice. 6.3.2. General view of the technological schedule of the hump operation with one hump locomotive



The duration of the hump cycle is determined from the technological schedule
Time to perform a group of operations characteristic of a given chart, the location of which is repeated on the chart. According to the value of Tg c it is possible to determine the average time a hump is occupied by disbanding one train and the processing capacity of the hump.
As can be seen from Fig. 6.3.2., the duration of the hump cycle (the period between two settlings through three trains) is equal in this example to 57 minutes. During this period, three trains were disbanded, therefore, the hump interval
min.
When one locomotive operates on a hump, the hump interval is numerically equal to the occupancy of the locomotive when disbanding one train. Recycling capacity of the slide
