He will take over at chief executive officer from previous owner John Murphy who has retained a significant stake in the business and becomes executive chairman.
Quattro Group was founded by Murphy in 1989 and has since grown into a £40m business suppling operated road rail plant in the UK.
Murphy said: “Having built the business over the past 24 years, the time is right to further its development by passing control to the management team.
“The buyout is all about maintaining the momentum of the organisation, and my new role as executive chairman means I will remain involved as the management team take Quattro Group on to the next phase of its development.”
New CEO Callé has been involved with Quattro Group since delivering the acquisition of BCL Rail Plant in July 2008, a move that doubled the then size of the organisation.
Callé said: “We have some very interesting ideas for the future. We plan to continue to grow the organisation, developing and improving existing services.”
