About Us

Located close to Central Otago’s fruit growing region, EB’s are specialists in fruit-handling conveyors and equipment that ensures growers excellent returns on their premium products.

Our machinery has revolutionised the sorting, sizing, packing and grading of cherries throughout the industry.  Ongoing innovation in packhouse systems has resulted in an evergrowing list of complementary products, including cherry bagging systems, bucket-wash, semi and automatic weigh systems.

We have also developed complete packhouse systems for handling fruits and vegetables such as apples, apricots and potatoes.

We believe there is no limit to the produce handling needs that we can service. Every system we design is unique to meet your specific needs.


EB Engineering Solutions was established as E B McDonald Ltd in 1945  by Ebb McDonald as a tractor/farm machinery repair shop in Crawford Street.

Employee's Joe Wansink and Bill Hunsche bought the company in 1964, deciding to change its focus from farming to industrial maintenance (including such brands as Shacklocks, Reid Farmers, Dalgety) and special projects (boats, gang mowers, coring machines, presses to name a few).

Since then we have been actively developing our resources to meet the needs of a changing industry. In June 1998 we received our registration as a Telarc Q-Base Registered Supplier.

In 2002 we simplified our name to EB's Engineering Solutions, which we felt reflected the variety of services we offer our customers.

And then in 2012 we dropped the 's from EB's to trade as EB Engineering Solutions.
