Spare parts dispenser
A spare parts dispenser is a technical device that is no longer used for its original purpose , but is kept ready to remove spare parts or more complex assemblies . Other devices of the same or similar design can then be repaired in the event of a defect with still operational parts from the spare parts dispenser .
Most of the time a spare parts dispenser was already defective before it was put out of service; repairing it yourself is often no longer economical . It is characteristic that the spare parts dispenser is still recognizable in its original form and, at least externally, still appears largely undisassembled.
Compared to the storage of the already isolated, used spare parts, a spare parts dispenser has the advantage that the components remain in their original installation location, so to speak, remain cataloged and can be easily found without additional effort. The disadvantage is that the parts first have to be removed and checked for usability if necessary, and that those parts are also stored and require space that will probably never be used again as spare parts. For example, in the case of a motor vehicle, the complete chassis is rarely in demand as a spare part; comparatively small wear parts such as bearings , clutches or brakes are much more sought-after .
Basically, all parts removed from a spare parts dispenser are no longer as good as new and before using them in other devices, it must always be critically examined whether further use is safe and economically feasible. Nevertheless, it is common for commercial aircraft , for example, to be kept available as spare parts dispensers .
In some cases, spare parts dispensers are the only way to get replacement parts. Original spare parts cannot be procured, for example, if they are not available in certain regions or countries due to import restrictions , or if the supply of spare parts by the industry has already been discontinued due to the old age of the entire device or other economic reasons ( obsolescence ).
Defective devices are also acquired specifically for the purpose of obtaining spare parts. In the case of motor vehicles, for example, there is a significant market for accident cars . Since working time always has to be invested in the expansion of spare parts, the attractiveness of using spare parts dispensers decreases with rising wage costs.
The removal of parts from a spare parts dispenser is often referred to colloquially as canning .
