| History |
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
For almost 30 years, Vervaet has been producing big-tank sugar beet harvesters, which are capable of topping, lifting, cleaning, loading and transporting the sugar beet, in one go and with one driver. It goes without saying that in those years, a lot of experience is gained, where Vervaet constantly improved the machine, giving it more capacity, more cleaning, more reliability, easier handling, and all this with the lowest possible maintenace costs. All this knowledge and experience is incorporated in the latest Vervaet 17-tonnes tanker harvester. A team of well trained mechanics and a big stock of spare parts, together with the support of Vervaet managment, give you the service and back-up that you've always wanted, but were not able to get elsewhere. The way we operate, makea it easier for you as owner/driver to lift sugar beet, with the minimum costs possible.

| TOPPER |
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
To start with the front; the topper is already something special. The complete casting and the auger trough, are made out of 6 mm hard-wearing steel, to withstand stony conditions. This construction at least triples the toppers lifetime. The flail-shaft has a larger diameter which gives a bigger circumference of the flails. This means that you can operate the topper at lower speeds. (500-600 rev./min.). It is also possible to speed the topper up to 1400 rev/min and shut off the auger, so that the leaf is completely mulched. V-formed caps inside the topper ensure that the mulched leaf is put on rows, between the beet. This is mostly used when opening up a field so the leaf is not obstructing you the second time around. 1) Fold up the leaf spreader (from the cab) |

| On the lifter, Vervaet has been using rotating walking shares since 1978. This system has the unique quality that the shares make a rotational circle in the ground, independently of each other. This way, always one of the two shares make a lifting movement, (20 per second) in contrast with vibrating shares. Another great advantage of our system is that stones don’t get blocked between the shares.The speed of the lifting shares is adjustable from the cab, driven by double V-belts, which are light,strong and easy to replace. The lifting elements are mounted on a pivoting shaft, which follows the rows of beet very easily (without bearings) to eliminate root breakage. In total, there are only 24 bearings on the whole unit. Naturally the lifting unit is served by an automatic depth control. |

| Via the up-and over elevator, the beet are dropped into the tank. The elevator itself is situated between the front and rear wheel, so that it never touches the ground in extreme wet conditions. Unique to the Vervaet, the elevator automaticly moves up and down with the pile of beet inside the tank. This gives you the following advantages: 1) very little free fall (less damage) 2) tank fills evenly (perfect weight distribution) 3) large holding capacity With the elevator down, the free fall is kept to a minimum, to prevent beet-damage. The speeds of the roller-bottom and the discharge elevator are independently adjustable. The very quick discharge (17 tonnes in 30 seconds) gives you a biggeroverall capacity. The discharge-elevator has a 'swan-neck', to completely fill high trailers. The sprockets are not running in the spokes, but only in the rubber, wichgives the continental web a longer life time. |

| Tyres |
|

| The front tyres 850-60 x 38 (34 x 38) are a lot bigger than the ones which are normally used 800-65 x 32 (30,5 x 32) resulting in a lower ground pressure than the competition.

| Engine and Hydraulics |
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Since the first machines, Vervaet has choosen DAF engines. This truck engine has a very reliable reputation and a good service network all over Europe. The 12,5 litre turbo-intercooling gives the machine 380 HP, or even 430 (optional) for very hilly conditions. The engine is mounted on silent blocks to prevent noise and vibrations. All functions are hydraulic driven with fast running hydro-motors, their speed reduced by gearboxes, creating maximum torque. Consequently, the turbines never stop, even when they are touching the ground. Power loss and oil temperature are kept to a minimum, resulting in a very long lifetime for the hydraulics. The unique traction control is computer steered and prevents wheel slip, without compressing the oil flow. |

| Maintenance |
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
The engine is very accessible for daily maintenance, such as checking and filling engine oil, coolant, and cleaning the air filtre. For safety and ease, we fitted steps, so the driver doesn't need to climb on a wheel or a separate ladder. The standard automatic lubrication system further reduces the daily maintenace to a couple of minutes. The engine is completely isolated to reduce noise level and give a neat appearance. A standard air compressor is handy to clean the radiator or inflate the tyres. The entire machine is built with attention to quality for long service and low running costs. |
