Transportation of cement - Management
The objective of this course project to identify five specialized vehicles most efficient car for the transportation of the specified load (ie cement in bags).
All used cars are equipped with tents, for greater safety of the physical-chemical properties of the cargo. Which in turn imposes certain imprint on the performance of loading - unloading. Ie loading - unloading can be done only through the tailgate of the vehicle.
In this course project is considered mechanized - manual handling option: paketoformirujushchee machine puts the bags on pallets, electric pallet moves directly into the body of the car where there is an overload and stacking bags from a pallet on the floor of the truck loaders. Shipping pallets wasted due to the geometric dimensions of the pallet 1240h840h160.
In carrying out the calculation of the threshold coefficient adaptation Body SS on duty were the most adapted geometrical parameters of the car GAZ-3307, since it has the least molded depth.
When comparing the SS on the technical and operational indicators
(Hourly productivity in tons (Wq) and t.km. (Wp)) it became clear that most car manufacturers truck KAMAZ-5410 + n / pr OdAZ-9370.
When calculating the fuel consumption rates in five brands of PS can be seen that the AM GAZ-3307 the lowest fuel consumption. The biggest fuel consumption of trains KamAZ-5410 + n / pr OdAZ-9370.
In calculating the time of delivery was found that the minimum time for delivery of cargo spends GAZ-3307. But as the difference is very small and insignificant we can say that all the cars spend equal time for shipping.
However, the choice of rolling stock in terms of productivity and turnaround time is not final, as there is always a car, having a large production, minimizes operational costs. In addition, the performance measure does not reflect the economic efficiency of the rolling stock. Therefore, for the final solution of the problem it is necessary to compare selected models of rolling stock on such final indicator as transportation costs. The cost of transportation is a general indicator for assessing the effectiveness of the use of a particular brand of rolling stock. Therefore, economically viable and profitable will be rolling with a minimum value of cost, namely tractor KAMAZ-5410 + n / pr OdAZ-9370.
11. The structural part
Calculation of the connecting rod bolts.
The gap is due to the connecting rod bolts:
1). Insufficient strength bolts, and is accompanied by disclosure of the joint and the formation on its surface work hardening;
2). Excessive tightening of the bolts, accompanied by stress of the material with a further loosening.
Destruction of bolts may also wear a purely fatigue character of additional bending stresses caused by insufficient rigidity of the head and crank neparalelnostyu bearing surfaces of the bolt head and nut. The magnitude of these stresses can not be taken into account by calculation. According to experimental data, the bending stress may constitute 25-30% of the tensile stresses arising when tightening. To reduce bending stress reduces the diameter of the bolt head and nut and spherical bearings are used.

Scientific and technological progress in transport developed in the following areas: integration and unification of the packages; specialty vehicles and means of the processing load on the entire en route; greater organization, mechanization and automation of technological processes; representation of complex transport services at coordinated technical and operational cooperation between all modes of transport involved in integrated systems through a demon reloading messages optimal routes "from door to door."
The transport process is the most dynamic element of the transport condition of the goods, which as a result of scientific and technical progress undergoes substantial transformation.
Impact of the transport of the cargo for transportation and transshipment facilities and transportation technology was particularly evident when transporting small sized cargo.
Small sized loads in all large quantities are transported in the form of consolidated packages. In the first stage as a means of strengthening the packages were used packets generated on universal pallets. Performance of production lines increased. Organization through traffic "from door to door shipper consignee" helped to solve three major problems of transportation:
1.Sokratit total time of delivery;
2.Snizit cost of transportation;
3.Avtomatizirovat process accounting and planning of traffic flow.
All this led to a radical restructuring of the transport system. In the field of logistics needed to create a park of large containers that meet international and national standards and specialized vehicles; build terminals with powerful conveyor technology; create a container areas at railway stations, river wharves.
For permanent loading and unloading points characteristic uniform selection of elements that make up the complex equipment required for the normal operation of the points.
These elements are: warehousing, consisting of closed storage space, as well as open and semi-enclosed areas for storage of goods; weight of the device; means of mechanization of loading and unloading operations in the required quantity and variety, change of working equipment to and rigging equipment; means of rapid communication, etc.
One of the most widespread means of mechanization of cargo handling and storage operations are roller track. Roller tracks generally consist of a frame and multiple rollers which are arranged parallel to each other and perpendicular to the direction of movement of the load. Cargo moving on the roller track from top to bottom, encounters very little resistance to the rotating rollers to overcome the track which is sufficient to give the inclination angle of the horizon 2-6k.
From other small machines that benefit when working in warehouse conditions, it is worth mentioning-handcarts transpaletty specifically designed for loading and unloading operations related to the movement of goods in containers or small or packaged on pallets standard sample. Transpaletta a fork hand truck with a hydraulic lift. The trolley consists of a frame with a fork, hydraulic pump, fork lift drive, two front swivel wheels and running two rear road wheels.
1.Zadanie on the course project
Type of cargo: cement in bags
The annual volume of 14,977 tons perevozok-.
Number of shippers -1 (cement plant)
Number gruzopunktov- 5
Plant manufacturing reinforced concrete structures
The distance between the consignor and the consignee 12, 44, 88, 97, 133km.

Based on the needs of the customer (the urgency of delivery, mode of storage of goods, operation service companies in the conditions stipulated by the contract, etc.), establish the range of import cargo.
We define the average daily demand for cargo Qcc, t / day;
where Dp-working days, Au ? The use of the park, n-number of consumers.
Since the demand at the store one ton of cement per day, the goods will be delivered 1 time in 15 days. At the warehouse №1 - 2 times in three days, respectively, as he need to 10 tons of cement per day. At the warehouse №2 PONV. 20 tons of cement per day, delivery means will be 3 to 4 times a day. At the construction site every day requires 2 tons of cement delivery - 1 time for 8 days. Finally Reinforced Concrete consumes daily 45 tons of cement, of course delivery will be 3 times den.2.Gruz and transport characteristics.
At different stages of the economic cycle production-transportation-consumption, the result of work every time is a new quality. In the first stage (production) of the material is the result of social labor product, ie category that has value and use value. The product can completely or partly be used for consumption or sale elsewhere-product. In the second stage from the transfer of transport for spatial displacement product becomes cargo, ie object transport. In the third stage, i.e. in the implementation of consumer cost, load again called product. Under the scheme: the product-item-load product.
Cargo transport characteristics is a property of the goods, which manifests itself in the process of transportation and defines the process. In cargo transport characteristics include: physical and chemical properties, volume-mass indices, packaging, storage modes, congestion and transportation. Specific set of qualitative and quantitative characteristics of the transport cargo vehicle called the state of the load.
Cement refers to construction materials to the 1st class of solid cargo in Division-packaged packaging and piece goods. The group require protection from the environment.
Cement requires protection from moisture. When wetting the cement hardens and thus making it unsuitable for further use. And zatarivatsya hot.
Cement is transported in paper bags. Dimensions of the package: 750-400-160mm and weight 50kg. Stowage volume of 0.7 m / t.
2.3.Tara, packaging, labeling cargo.
In bags carry a variety of loads that do not require protection from mechanical damage. Bags are soft packaging material for manufacturing are fabric, paper, plastic and bast. Sizes of bags are set by state standards.
In the standard documentation for the carriage of goods, packaging is encrypted alphanumeric code. Code number defines the kind of packaging, the letter-rod material. The first group of numbers defines the shipping container, the latter - Consumer 12B-12B.
Paper bags are produced multilayer (up to six the number of layers). Tarred paper bags are airtight and waterproof, acid-resistant. At elevated temperatures and humidity decreases the strength of bags, especially paper. It is important for the safety of cement, which zatarivatsya hot.
Marking referred to various inscriptions, drawings, signs and symbols, which are applied to the packages. The label indicates: Destination prescribed by cargo, type of cargo handling during storage, handling, transportation, unpacking.
Markings: here open - open, here-hier, offnen-ouvrir ici (Russo-angl.-nem. Fran.); net mass-netto-nettogewicht-peidc net; place № - case№ - kollo NR - colis N; purchase order № - nariad № - nariad№; export - export - export - export; and m. d.2.4.Rezhim storage. The method of storage.
For storage of cement is better to use non-heated or metallic cal warehouses. For storage of goods used in flat stacks, rack-mount
pallets; bespolochnye racks and frame cell, blind, communicating, gravity, mobile, console, W - shaped shelves.
Industrial warehouses are an integral part of the overall production process. They affect the overall
rhythm and organization of production, in-plant traffic flows, external transport delays in cargo fronts the company, its layout, etc.
By appointment industrial warehouses are divided into the following: storage material - logistics, storage of finished products, production - technology stocks.
To the storage of material - technical support, include all works general warehouses, through which the company receives raw materials, materials, products; blanks needed for production. One of these is the warehouse inventory - general cargo, which stores a variety of goods in boxes, barrels, bags and so on. D.
Warehouses material - technical supply the following functions: reception of products for industrial purpose in quantity and quality of enterprises and transport organizations; loading and unloading from vehicles; Order of road transport for centralized export of goods to consumers; storage of goods in accordance with the required standards from the moment of arrival to the issue of transport for delivery to consumers; Picking, packaging and delivery of materials at the request of consumers; registration documents received and issued from the warehouse goods, accounting and reporting on acceptance, delivery and availability of goods in stock; periodic inventory of stocks and goods.
The characteristic features of the material warehouses - logistics are large periods of storage of goods (from 20-25 days in the warehouses of industrial enterprises, up to 70-90 days or more on the supply and marketing material bases - logistics); arrival of goods external transport, and hence perhaps more uneven traffic
Arrival and large batches of arrival of goods; the need for good communication and clear technical, economic and legal relationship to the railway station and trucking companies to deliver goods; the need to link with a large number of suppliers of goods and so on. d.

4.Sposob loading and unloading.
In road transport, various forms of handling. The most common of these is the performance of work by means of consignors and consignees at constant consolidation of cargo handling machines, machine operators, cargo
sors and slingers of freight positions or points. In this form is achieved the need for specialization of workers and machines for production conditions of loading and unloading, cargo mind, to the types of rolling stock, which ultimately contributes to increased productivity in loading and unloading cargo.
Loading cement sent in bags, carry out small-sized battery forklift.
Similarly are unloaded cement.
Depending on the vehicles for loading (unloading) manavrirovanie forklift has more or less complex, because it can only produce PR by operation previously open side of the vehicle. The trajectory of the truck also depends on whether the vehicle parallel or perpendicular to the stack of cargo and whether to loading (unloading) from the rear, one or both side walls.

Operating expenses consist of the following cost items:
1). The main and additional wages of drivers with deductions.
2). Fuel costs.
3). Expenditure on consumables.
4). Maintenance costs and maintenance.
5). Expenditure on compensation of wear and tire repair.
All these articles are costing divided into two groups of costs: variable and fixed.
The cost of fuel and lubricants, maintenance and repair of rolling stock, compensation of wear and tire repair, depreciation on rolling stock with the currently existing methods of rationing vary depending on the vehicle mileage. These groups have varying cost.
All other costs are called persistent because they do not depend on the path. When you split the costs into variable and fixed, wages of drivers conventionally assumed to be constant.
Variable and fixed costs include the costs of transport companies and automotive component called the cost of transportation.
