Emergency services flocked to the site after it became clear the man was stuck 30 metres above the ground at Tilbury Docks and a specialist trauma surgeon was flown in from Cambridge to help him as teams tried to release him.
Fire crews from Orsett and Grays, a search and rescue team, the ambulance service, including five hazardous area response teams, and an air ambulance were called to assist the man this morning.
It is not known how the man got stuck but he is currently being assessed by doctors.
The extent of his injuries is currently unclear.
Earlier, Assistant Divisional Officer Mark Turnbull had said: “The crane company is bringing in specialist equipment which will loosen the tension on the gears so that firefighters can perform a rescue. We anticipate it being two to three hours before the casualty can be released but we are making him as comfortable as possible and paramedics continue to assess his condition.”
EEASTs Media Manager Gary Sanderson said: “The patient has now been freed from the crane and HART paramedics and the medical team are in the process of stabilising him further before he is airlifted to the specialist trauma centre at addenbrookes hospital.”
