ABSTRACT:
A device for lifting an upper part of a curing press steam chamber includes rollers which move along guideways. The lifting device allows an upper part of the steam chamber to be lifted off a lower part of the steam chamber and moved laterally to allow easy access to both the upper part of the steam chamber and the lower part of the steam chamber. A linear motor moves the rollers along the guideways to lift the upper part of the steam chamber off the lower part of the steam chamber. The linear motor may be a translating screw or a hydraulic cylinder motor. A longitudinal axis of the linear motor forms an angle with the guideways which is smaller than a right angle at all positions.
