Plantforce has a capital expenditure of £12m this year to invest in updating its fleet.
Some new equipment already available to hire includes new Generation 10 Kobelco excavators and HX series Hyundai excavators.
As well as fleet expansion, Plantforce is also investing in new facilities. It is moving into custom-built offices at its premises in Weston-super-Mare later in the summer.
Managing director Claire Trott said: “This is a really exciting and busy time for Plantforce. With our investment programme for 2017 we are looking to expand our extensive fleet so that our customers can benefit from brand new, reliable, fuel efficient machines, equipped with the latest technology and backed up by our exceptional, bespoke service.”
