A C-yoke (2) configured to handle a wind turbine blade (4) is disclosed. The C-yoke (2) comprises: a yoke member (6) extending between a first C-member (8) attached to a first end of the yoke member (6) and a second C-member (8') attached to the other end of the yoke member (6). The C-members (8, 8') comprise a support member (10, 10') configured to receive a wind turbine blade (4). The C-members (8, 8') comprise a clamp member (18, 18') and means (24, 24') for displacing the clamp member (18, 18') relative to the support member (10, 10'). The support members (10, 10') have a contact surface that has a geometry corresponding to the outer geometry of the wind turbine blade (4). The support members (10, 10') are provided with a number of (rubber) pads (20, 20', 20") having a coefficient of static friction, µ s , that allows for tilting the wind turbine blade (4) into an angle (¸) up to at least 25 degrees, such as 30 degrees relative to horizontal (H), without providing any additional force towards the wind turbine blade (4) by using the clamp members (18, 18').
