A lorry driver was injured at the Port of Felixstowe last week after a 40ft container was dropped onto his truck, crushing the vehicle and trapping him in the remains of the cab.
Four fire engines and the ambulance service were called to the Port of Felixstowe just after 5pm on Wednesday evening (21 April).
Suffolk Fire and Rescue Service said cutting equipment was used to rescue the man from the cab.
East of England Ambulance Service dispatched an air ambulance, two ambulances, a rapid response vehicle and two Hazardous Area Response Team vehicles to the scene.
A Suffolk Accident Rescue Service (SARS) volunteer critical care paramedic was also mobilised to the incident and was first at the scene. The driver had to be cut free by firecrews.
A spokesman for the Port of Felixstowe said the driver had since been discharged from hospital.
He added: "A full investigation into the cause of the accident is being undertaken."
