Truck Transport

Coal-carrying vehicles are typically end-dump trucks with a carrying capacity of roughly 25-50 tons. Truck delivery is used extensively for small power plants in the eastern United States. 

Coal can be moved by truck over regular highways in vehicles with 15-30 tons capacity. Coal can also be transported by large off-road trucks with capacities ranging from 100 to 200 net tons. These trucks are almost always diesel-powered with back or bottom dump. 

Specially constructed roads for coal hauling are extensively used for mine-mouth power plants in the west, south, and east, while the hauling of coal by trucks on highways is more concentrated at surface mines. Truck hauls on public highways in the United States typically range from approximately 50-75 miles while off-road hauls are approximately 5-20 miles. 

Trucks are the most versatile of all transportation modes for coal hauling because they can operate over the widest areas where roads are available.

Truck transportation is used to move coal to a transloader for placement onto a water or rail carrier, or for direct shipment to the customer. Trucks have the advantage of routing flexibility and modest capital rcquircliiclits, but coal can be ccoiiniiiically transported for at most about 100 miles (160 km) one-way nr less, due to the high unit cost of moving a low-value product in relatively small batches. 

Elemental sulphur from the final condensers flows to the sulphur pit where it is available in a molten state for shipment by truck transport or transfer to a storage block. Sulphur which is removed from site travels south to the Edmonton area. A significant portion is used for fertilizer production. 

Barge and Truck Transport of Coat. Approximately 28% of U.S. coal is transported by barges over inland waterways. Trucks account for approximately 13% and used ntairly for deliveries of l(M) miles (161 kilometers) or less. Because of weight limitations, trucks are not used for long hauls. 

Trucks transporting expl materials to burning grounds should meet the requirements of Ref 5, seen 22. The expl material transported should be covered with a tarpaulin and no more than two persons should ride in the cab. While the material is being unloaded at the burning ground the motor... 

It follows from economical comparison that coal-log pipeline is cheaper than truck transport for distances longer than 65 km and pipe diameter D = 200 mm. For D = 500 m even for distance over 25 km. Compared with railway, the transport cost is on the level of unit trains. For large quantity of coal it could be even less. Another advantage is given by fact that length of pipeline is usually at least about 30 % lower than that of the railway. From environmental protection point of view, capsule pipeline, similarly as slurry pipeline, is dust free and noiseless. In spite of these advantages the utilisation of coal-log pipeline system could expect only for transport of coal from new mines to power stations, especially in mountains areas without railways and highways or in heavy populated and industrial areas, where railway is overloaded. 

Some models also include transportation mode selection (e.g., air freight, ship or truck transport, full container load or less than container load) either solely based on cost comparisons or also considering the trade-off between transportation costs and pipeline inventory or lead time (cf. Zeng 2002 Vidal and Goetschalckx 2000, pp. 106-107 Jayaraman 1998, pp. 474-476). Due to the limited importance of transport costs in specialty chemicals and the fact that products are typically transported between plants and markets in full container loads this level of detail does not provide additional insights.

Fig. 2. Pipeline and truck transport cost of wood chips at fixed distance of 160 km.

Note that unlike truck transport, there is an economy of scale in slurry transport of materials, since larger throughputs benefit from an economy of scale in construction of the pipeline and associated equipment, and in lower friction losses in larger pipelines. 

From Figs. 1 and 2 it is clear that the marginal cost of transporting biomass by pipeline at a concentration of 30% is higher than truck transport at capacities <0.5 million dry t/yr (one-way pipeline) and 1.25 million dry t/yr (two-way pipeline) at a distance of 160 km. The implications of this finding are discussed in the next section. 

Pipeline transport of oil and natural gas is clearly far more economical than truck transport, even in relatively small pipelines. Three factors combine to make the transport of energy in the form of biomass far less economic ... 

It should be noted that for air, sea and truck transportation, electrification is not conceivable. For these applications, the only C02 emissions reduction option that will not limit growth will be in the use of clean fuels or synfuels. 

Truck transportation rates for anhydrous ammonia are relatively high because of liability insurance rates and the need to use specialized equipment. Distribution is further complicated by attempts to restrict the movement of ammonia in some jurisdictions. In 1990, the U.S. Department of Transportation classified anhydrous ammonia as a non-flammable gas and required shipments to be marked with the words inhalation hazard. International shipments are required to carry the inhalation hazard and poison gas markings57. 

A variety of shipping methods are used, which may include both company-owned vehicles and commercial transportation modes. Small-quantity orders may be shipped via UPS or a similar commercial delivery service. Many use a limited number of company-owned trucks to deliver products to local consumers. However, the overwhelming majority of bulk shipments are made using commercial freight lines (heavy truck transport). 

Distinguished from general transportation, which embraces the questions of rail, water and motor-truck transportation over long distances, material handling in the present chapter will be confined to the economic transportation of materials in and about the industrial plant or mine and over comparatively short distances—the conveying and elevating of material by the assistance of mechanical aids. 

Application of hot-mix paving mixtures is performed more easily with conventional equipment. Moreover, the distance of truck transportation is improved, because of the lower compacting temperature, which can be below the melting point of sulfur. In addition, with some formulations, compaction is not necessary.
