Following a record year in sales, Penny Hydraulics is set to better this again in 2016 with the end of year turnover set to exceed £7m.
A new line of over 470 hydraulic vehicle mounted cranes added to the existing crane range in April 2015 has also played its part.
The business remains family owned and is currently run by 2nd generation family members and a board of Directors. Robin Penny, son of founder John Penny and current MD of the company, says: "We have to continually invest in the people, the systems and the site that make up our business."
