info@crendon.com.au NetWizz Standard Mast Wide Top Loop Auto Tension"NetWizz Std Wide Top Loop Auto Tension" is a machine for applying and removing wide bird netting in large vineyards. Netting is wound onto a simple spindle in an inter-woven pattern like a roll of twine. The bottom frame is same as Std NetWizz this bottom frame is already made very heavy duty. The differences are.The wand is now driven via small hydraulic motor directly coupled to a worm drive gear box with shear bolt on the output shaft. This provides excellent shaped rolls every time. The Strong Top Loop is bolted together to make a 8.5m or 5.5m wide loop. The mast is made from thicker steel tube because of the heaver top loop |
|
8.5m / 5.5m heavy duty top loopA heavy duty wide top loop is available for the Std mast NetWizz. This is the same used on the Slim Heavy Duty model. This is strongly recommended when using netting 20m or wider. |
Fast, safe removal of netting without tearsIf netting gets caught the sensor automatically stops the spindle, preventing tears. The sensor automatically adjusts the spindle and wand speed to maintain a constant incoming net tension. Netting tension remains constant, no matter what size roll is being wound up or the tractor's ground speed. |
Shear bolt protection for top loop & mastThe NetWizz mast incorporates a heavy duty shear bolt assembly which breaks a small bolt, preventing the top loop and mast from damage. This arrangement is now a lot heavier than before, Ø24 pin in 10mm plate To work around power poles, trees and for transport, a spring loaded rotating pin is disconnected allowing the mast assembly to rotate. The mast is telescopic and is raised and lowered using its winch and can be locked at 3 height settings. |
| Self loading and unloading of netting rollsFull spindles are loaded using the tractor’s 3PL. The tractor is simply reversed into the roll, with the aid of self-locating guides, then raised with the linkage. If required, an extra roll of netting can be carried on the two arms which slide out. In its standard narrow setting (shown above), the larger roll is 15m wide x 300m long, the smaller being 10m wide x 100m long both on 1.1m long spindles. The steel spindles protrude from the end of the roll enabling easy safe mechanical handling. The new NetWizz models are easy to adjust in width from: |
Automatic speed and netting tensionNetting tension is easily adjusted (by turning a screw) to suit different strength nets. Once the tension has been set to suit the netting there is no need to adjust it again. All the tractor driver has to do is drive down the row and stop only if the netting becomes caught up on the vine trellis. No controls need to be adjusted while driving (retrieving or applying netting). |
Netting wound tight on steel spindlesNetting is stored from the vine on square steel spindles and end covers are fitted when in use. These covers have high sides and large sealed ball bearings for easy operation. New netting supplied in bags or on narrow rolls can be applied straight over the vine with the NetWizz without the need to first wind onto spindles. The NetWizz comes with 8 x 1.4m spindles which are stored in the holder. These spindles are 50mm square x 1.6mm thick, being 1.1m long for standard setting and 1.4m for the wide setting. |
Controlled net unrolling tensionWhen feeding out netting to cover the vines, the spindle hydraulic drive is simply disengaged which allows the net to unroll. A brake can be lowered onto the roll, allowing it to unroll at a set light tension regardless of diameter and also prevents over-run.

ImprovementsAfter 20 years, we have redesigned all NetWizz models. Frames are now much stronger, hydraulic motors 40% more powerful & 25% faster winding, top loop and mast from bigger steel, spindle drive coupling stronger, spindle covers stronger, bottom steel side & top plate now twice as thick, more compact, safer, easier to operate. The bottom frame is the same for Standard Mast Auto tension, High Lift Auto tension and High Lift Swivel Head Auto tension models. |
