The Longton company has a fleet of 14 mobile cranes ranging in lifting capacity from 12 tonnes to 220 tonnes.
Administrators from Deloitte have taken over at the Staffordshire firm, which has been trading for 33 years and hires cranes and lifting plans as well as offering staff and lift supervisors.
Longton has been struggling since 2009 with workers accepting reduced wages and sometimes only working four days a week instead of five or six.
