His business also does other mechanical and maintenance work, mainly for industry.
Since December last year Mr Plimmer has been working with Ean Cantell. He is a specialist in hydraulics. Forklifts use hydraulics and hydraulics were a natural extension to Mr Plimmer's business.
"We're now looking at growing our stocks of hydraulic hoses and fittings, and also making them ourselves. We think there's room for another player and we've purchased a new hydraulic press."
The company has five staff - two mechanics, an office person, and two to work with hydraulics. Mr Plimmer and wife Donna have had the business for 15 years.
