Abstract: A concrete mix casting equipment that can be dismountably attached to a crane, and method for controlling the same, by controlling motion of the casting equipment in the horizontal plane by moving the crane, and by controlling a substantially vertical motion of the casting equipment during the operation of the casting equipment by vertically moving the lifting element of the crane such that this engages the upper part of a lower frame of the casting equipment, thereby moving the lower frame of the casting equipment vertically relative to an upper frame of the casting equipment.

Abstract: A method for the installation of a lifting loop in a fresh hollow core slab, said hollow core slab having its top surface broken for an opening substantially in line with a neck between the cavities, and said method comprises placing in the obtained opening a lifting loop-forming part set to bear against the hollow core slab's pre-stressing strands, the lifting loop-forming part's end sections being placed under the hollow core slab's pre-stressing strands by providing either a permanent or temporary deformation in the lifting loop-forming part. The invention relates also to an apparatus for implementing such a method, as well as to a lifting loop-forming part compatible with the method.

Abstract: A method for bracing a lifting loop for a concrete element at least during a concrete element lifting operation effected by using the lifting loop, whereby the lifting loop is at least partially located inside a recess prepared on a surface of the concrete element, in which method at least forces, which are longitudinal relative to a concrete element to be lifted and which are applied to the lifting loop, are conveyed to the concrete element to be lifted by means of a support piece to be set at least partially in said concrete element's recess prepared in association with the lifting loop. The invention relates also to such a lifting loop support piece.

Abstract: A method for controlling concrete mix casting equipment to be dismountably attached to a crane, said casting equipment being controlled on the horizontal plane by moving the crane, so that a substantially vertical motion of the casting equipment is achieved during the operation of the casting equipment by vertical motion of the lifting element of the crane. The invention also relates to a concrete mix casting equipment to be dismountably attached to a crane.

Abstract: A casting mold sidewall unit including a sidewall part restricting the outer surface of the concrete product to be cast, as well as a sidewall part support structure, said sidewall unit including at least one removal device extending through the sidewall part, said removal device being at least partly movable outwardly from the sidewall part surface level in order to remove the sidewall unit from the hardened concrete product. Also, a removal unit to be connected to the sidewall unit.
