For over 20 years , contract doer have been working with hydrocarts during crop gyration to their complete satisfaction . Intensive use , however , stand for that after some time , more and more upkeep and overhaul are want .
ground enough for contractor to require APH Techniek , together with Sosef ( the developer of the first case of pipe - rail hydrocart at the metre ) , for a fresh version . This was worked on in recent years . Meanwhile , a epitome has been further developed into a version that is " 99 % " ready , say Ard Vester . " The cart has passed all mental test and is now break into the glasshouse for a field trial . "

Integration hydraulicsBoth last twelvemonth and last February , APH Techniek ’s Hydrokar Tube Rail Cart was on showing at the HortiContact horticultural trade fair . Last year as a image , and this class in the version that goes into the greenhouse with a contractor . " On the outside , the go-cart is very similar to the old model , " says Ard , owner of APH Techniek from Wateringen . For example , the big reel is still desirable for hose up to about 250 meters , and the pushcart is construct from stainless steel 316 and can be dismantled for maintenance . " But on the interior , a slew has changed , " he says .
A central point is that the entire fluid mechanics have been ' modernise . ' " Previously , for instance , the lever tumbler control was on top of the frame . This intend many hose had to run back and forth through the hydrocart . " Now , this is integrated into a particular pulley block at the bottom of the cart . Also , the valve blocks are no longer on top of the frame . " This has allow us to build easier and cleaner . "
Less vibrationAnother stage of advance is the placement of the engine block . The hydrocart is powered by a petrol unit . " Users set up its vibrations annoying . You have to imagine that abide all sidereal day on the platform , which vibrates solidly , is not nice . The vibrations from the locomotive went straight into the frame . Now we have suspended the railway locomotive in rubber dampers , and there are no more palpitation . "
Anyone wondering why the go-cart is still gasoline - powered in times when more and more systems are electrically powered pauperism to interpret how contractor use the cart , say Ard . " The hydro pushcart is used during crop rotary motion . This utilise a lot of water . Electronics do n’t like that . Moreover , there is no crop in the greenhouse at the sentence of use of goods and services , so the exhaust fumes do not baffle any problems for that . " summate to this the fact that changing barrage fire or charge them regularly is not necessary , and one understands why this solution was chosen .
An advantage of scaling up yield is that everything is ' draw out digitally .
Practical testEven apart from the drive , where the declarer can expend foot controls to move the cart forwards or backwards , there is no electricity involved in the cart . " Everything hold up hydraulicly . " Because many parts have been replaced by innovative alternatives , which allow more compendious construction , the joke is to get everything optimally in tune with each other . As an model , the technician gives the interplay between the dismission force of the Scottish reel and the involvement of the driving force . " This requires dynamic adjustment . All valve together have to see to it the function . It ’s not a question of ' just a switch . ' For example , you desire the reel to always originate rolling just a bit before than the cart set about driving . "
As shortly as grower set out changing their crop to , say , cucumbers or finish their winter crops , the declarer will go back into the greenhouse . This will involve subjecting the raw Hydrokar Tube Rail cart to its first existent hardheaded test . The contract proletarian who came to APH Techniek with the request for advance of the handcart will in all likelihood require to buy the first one immediately after a successful trial as well . After that , they hope to start producing multiple in Wateringen . " In the coming age , the current cart will then gradually be able-bodied to be replaced . "
