A Trailer = Mounted Crane for Infield Loading of Sugarcane
نویسنده
چکیده
A small, truck-type slewing crane with a grab was centrally mounted at the front of an 8-ton box-type tipping trailer. The crane and grab were operated by the hydraulic system of the tractor. Attempts to modify the control valves of the crane were not successful and it was concluded that the standard controls supplied for truck-type cranes were not suitable for this purpose. A standard double-acting valve control bank was fitted and the results were satisfactory. Considerable modifications were made to the grab for it to operate efficiently. Various oil supplies to the crane hydraulics were evaluated to achieve a loading rate of 20 t h-'.

Minimising Transport Costs through Optimal Upgrading of Roads and Loading Zones
Infield to zone transportation with agricultural tractor-trailer units may incur costs of up to nine times those of long distance truck-tractor units. This necessitates the implementation of an optimal cane extraction road network. This paper describes formulas derived to evaluate whether the construction of additional roads and loading zones could enhance a farms profitability. The formulas w...
متن کاملThe Performance of Machinery for Mechanical Harvesting and Loading of Sugarcane
The results of these studies showed that mechanical loader and combine harvester performance varied considerably depending on the type of machine, cane yield, and crop and field conditions. Instantaneous loading rates and mechanical harvesting pour rates varied between 60 and 100 tons per hour. Infield cane losses were significantly lower where the cane was manually cut and mechanically loaded ...
متن کاملLoading the problem loader: the effects of target training and shaping on trailer-loading behavior of horses.
The purpose of this study was to develop an effective method for trailer loading horses based on principles of positive reinforcement. Target training and shaping were used to teach trailer-loading behavior to 5 quarter horse mares in a natural setting. All 5 had been trailer loaded before through the use of aversive stimulation. Successive approximations to loading and inappropriate behaviors ...
متن کاملProduction, Management and the Environment: General
In addition to having methods for depopulation of commercial poultry flocks to contain outbreaks of serious avian disease, there is need to have an efficient and humane method to dispose of small flocks that might fall within an affected area. A modified atmosphere killing (MAK) chamber mounted on a trailer to be pulled by a pickup truck was designed for small flock depopulation. The atmosphere...
متن کاملSimulation and Experiment on Conveying Device of Cutting System of Small Sugarcane Harvester (RESEARCH NOTE)
The main problem is less efficiency and blocking during sugarcane harvesting in hilly areas. This paper researched the cutting and transporting system of a small sugarcane harvester using virtual prototype technology. The dynamics simulation analyses were carried out to study the transporting status with different friction coefficients between the sugarcane and the spiral and different numbers ...
