Abstract: Devices and methods for making hollow concrete elements are disclosed. A device includes a drum mold having a tubular mold wall. The mold wall has a first and a second end flange each with an inner periphery smaller than the inner periphery of the mold wall at each respective end. The device further includes a compaction roller positionable inside the mold wall. The compaction roller has a profile that defines the interior shape of the concrete element. The compaction roller is supported by a hydraulically height adjustable supporting mechanism that is operable to independently adjust the distance of each end of the compaction roller with respect to the inner periphery of the mold wall.

Abstract: An antenna mast for a wireless communication system is provided. The antenna mast comprises a mast body that is configured to form a supporting structure for an antenna arrangement of the wireless communication system at an elevated position on the antenna mast. The mast body is also configured to house therein a transceiver arrangement and a processor adapted to perform random user-related communication operations in a cell of the wireless communication system, the cell comprising the antenna arrangement, the transceiver arrangement, and the processor. The mast body is further configured to house at least part of a device to be utilized for a function other than supporting the antenna arrangement. The device comprises a communication interface for establishing a connection with the wireless communication system. A method of providing a further function in an antenna mast for a wireless communication system is also provided.

Abstract: The present invention aims to provide an antenna tower structure comprising an essentially vertical elongated tower body with an internal installation shaft provided therein. One or more radio base stations are arranged in the installation shaft in the vicinity of one or more associated antennas at the top of the tower body. The installation shaft is formed to allow personnel access to the radio base station. The tower body is comprised of a metal-reinforced concrete material, and the mass ratio between the tower body and the radio base station equipment together with the antenna arrangement exceeds 15:1. The tower body is formed so that the mass center of the tower body and radio base station equipment is lower than ½ of the tower body height.

Abstract: A telecommunications tower segment for the construction of a section of a telecommunications tower is disclosed. A plurality of such segments is adapted to form a tubular section of the telecommunications tower. Each telecommunications tower segment has a convex first surface. Additionally, each telecommunications tower segment has a second surface opposite to the first surface, wherein the second surface is flat or partly flat.

Abstract: A method of making an open ended hollow concrete element includes arranging a mold about a substantially horizontal roller shaft, the mold having a sleeve-shaped mold wall defining the outer peripheral shape of the concrete element and first and second end rims, each with an inner periphery smaller than the inner periphery of the mold wall at the respective end and defining the end surfaces of the concrete element. The mold is rotatably supported by the roller shaft by abutment at the inner peripheries of the first and second end rims so that the roller shaft upon rotation defines the inner peripheral shape of the concrete elements. The method further includes rotating the shaft to rotate the mold; feeding curable concrete to the rotating mold; stopping the rotation of the mold; and removing the cured concrete element from the mold. The inner perimeter of the mold wall defines an exterior shape of the concrete element that varies along and/or radially to the direction of the rotational axis.
