The Enquirer understands that a deal is imminent and set to be confirmed across the company.
In January HTC Plant sold its UK hoist division to Dutch specialist Reco to concentrate on its “core market” of tower cranes.
But the Enquirer now understands that a sale of the tower crane business is set to be rubber stamped by Harrington.
The buyer is believed to be German manufacturer WolffKran who supply HTC with its machines.
HTC – which stands for Harrington Tower Cranes – was formed in 2002 when PC Harrington Contractors acquired the tower crane division of Hewden Stuart.
HTC added to its fleet in 2013 with the acquisition of Kier’s crane division which consisted of 40 machines and 25 staff.
HTC has a workforce of around 180 drivers and its red cranes are a familiar sight on major projects across the country.
PC Harrington declined to comment on a possible sale.
A site source said: “We’ve been told it is a done deal and Harrington will let everyone know about the change today.”
