The present invention relates to a mould assembly (100) for manufacturing a wind turbine blade shell part, and to a method of manufacturing a wind turbine blade shell part using the mould assembly (100). The mould assembly (100) comprises a lowering device (85), which is adapted to carry and lower a root end insert onto the moulding surface of the mould, the lowering device (85) being attached to the mould and comprising a frame (86) for carrying the root end insert. Two synchronized hydraulic cylinders (91, 92) are used as driving means for lowering the frame, each hydraulic cylinder comprising a piston chamber and a rod chamber, wherein the piston chamber and the rod chamber of each cylinder are connected to each other via a respective valve assembly (110) comprising a fluid line (96) and a valve (97).
A mould assembly (100) for manufacturing a wind turbine blade shell part, the mould assembly (100) comprising a mould (23) having a moulding surface (22) that defines the outer shape of the wind turbine blade shell part, the mould having a longitudinal direction extending between a tip end (26) and a root end (25) of the mould, wherein the mould assembly (100) comprises a lowering device (85), which is adapted to carry and lower a root end insert onto the moulding surface of the mould, the lowering device (85) being attached to the mould and comprising a frame (86) for carrying the root end insert, wherein the lowering device (85) further comprises driving means for lowering the frame together with the root end insert, the driving means comprising two synchronized hydraulic cylinders (91, 92), each hydraulic cylinder comprising a piston chamber and a rod chamber, wherein the piston chamber and the rod chamber of each cylinder are connected to each other via a respective valve assembly (110) comprising a fluid line (96) and a valve (97).
A valve assembly (110) for connecting two chambers of a hydraulic cylinder, each chamber comprising a fluid port, the valve assembly comprising a fluid line (96) with a first fitting (116) at the first end of the fluid line, and a second fitting (118) at the second end of the fluid line, the first and second fittings being connectable to the respective fluid ports of the hydraulic cylinder, wherein the valve assembly further comprises a two-way valve (97) arranged with the fluid line between the first end and the second end, wherein the first fitting comprises a hydraulic pressure test point coupling (124) for bleeding air from the hydraulic cylinder.
