Abstract: A method for casting a hollow core concrete product with a substantially horizontal slipform casting process, where concrete mass is fed at least in one feeding stage through a limited cross-section (5, 6, 7) moving progressively along with the cast, and at least one core is formed in the concrete product to be cast with a core forming member (4), wherein the thickness of webs between the cores of the product to be cast are changed during the slipform casting process by changing the width of the at least one core forming member (4). The invention also relates to such an apparatus and a core forming member.

Abstract: A method for adjusting a sidewall unit (1) of a casting mold for concrete products, which sidewall unit comprises a support structure (2, 32, 42) and a mold surface plate (3, 3?, 33, 43) fixed to the support structure, and which sidewall unit is fixed on a casting bed (8), wherein the mold surface plate comprises at least two portions (3, 3?) extending along the length of the sidewall unit and connected to the support structure (2) and the vertical position of at least one of the portions (3), defined by orientation of the sidewall unit (1) fixed on a casting bed (8), is adjusted to form a gap (9) extending along the length of the sidewall unit between the portions. The invention also relates to such a sidewall unit.

Abstract: An apparatus for sawing cured slipform cast concrete products, which apparatus comprises a frame with wheels, and a concrete saw connected movably to the frame, wherein the apparatus comprises a brushing unit for cleaning slipform casting bed.

Abstract: Method for lifting a concrete product with a lifting boom and a lifting boom, in which method the lifting boom is moved above the concrete product to be lifted with a crane, lifting hooks of the lifting boom are set in lifting loops located in the concrete product to be lifted, and the lifting is carried out by lifting the lifting boom together with the concrete product with a crane, wherein the location of at least one lifting loop in the concrete product to be lifted is detected by a control system of the lifting boom, which control systems moves at least one lifting hook along the lifting boom to the location of the lifting loop.

Abstract: A method and an apparatus for casting concrete products with a substantially horizontal slipform casting process, where concrete mass is fed through a restricted cross-section defining the product to be cast, and which restricted cross-section moves progressively along with the casting process in relation to a casting bed, wherein the height of the cast product exiting the restricted cross-section is measured during the casting process, and the height and/or position of the leveling plate of the upper surface of the restricted cross-section is adjusted during the casting process based on the height measurement of the cast product.
