Abstract: This invention relates to a bulkhead unit, a wind turbine blade comprising the bulkhead unit, a lifting device and methods of assembling and installing the bulkhead unit in the wind turbine blade. The bulkhead unit comprises a bulkhead element substantially extending in a radial direction and a frame structure attached to the bulkhead element. The frame structure provides support for the bulkhead element and additional components mounted to the frame structure. The frame structure comprises a plurality of frame elements which are interconnected to form a number of areas that are aligned with corresponding openings in the bulkhead element. The lifting device is used to lift the bulkhead unit into position and fix the bulkhead unit relative to the blade shell.
