Abstract: A method for pre-tensioning a chain conveyor, the method relating to a chain strand which is deflected by at least one chain wheel, wherein at least one measurement module is integrated in the chain strand and transmits data wirelessly to a communication device arranged outside the chain strand. The pre-tensioning force is adjusted according to the data collected and transmitted wirelessly by the measurement module.

Abstract: An eyebolt for releasably connecting a carrying, lashing or traction member with an object includes a threaded bolt and an eyelet. The threaded bolt has an inner bearing part and the eyelet is connected to an outer bearing part which with the incorporation of rolling elements is supported on the inner bearing part. The rolling elements are disposed above one another in a ring around the inner bearing part in at least two planes extending spaced apart and parallel to one another. Rolling elements disposed in a first plane have a radius and rolling elements disposed in a second plane have a radius. The sum of the radius of one of the rolling elements disposed in the first plane and the radius of one of the rolling elements disposed in the second plane is greater than the spacing between the planes extending parallel to one another.

Abstract: A method of adhesively bonding a strain gauge in an opening having the steps of providing a component, cleaning the inner lateral surface of the opening, providing an insert, wherein the insert has an outer lateral surface which corresponds essentially to the inner lateral surface of the opening and, on its outer lateral surface, has a mount for the strain gauge, wherein the strain gauge is positioned in the mount, introducing an adhesive into the opening and/or applying an adhesive to the strain gauge, positioning the insert in the opening, wherein the strain gauge is moved into the vicinity of that region of the inner lateral surface on which it is to be fastened.

Abstract: The invention relates to an eyebolt for releasably connecting a carrying, lashing or traction means with an object, comprising a threaded bolt (2) and an eyelet (3), wherein the threaded bolt (2) has an inner bearing part (10) and the eyelet (3) is connected to an outer bearing part (4) which with the incorporation of rolling elements (12a, 12b) is supported on the inner bearing part (10), wherein the rolling elements (12a, 12b) are disposed above one another in a ring around the inner bearing part (10) in at least two planes (E1, E2) extending spaced apart and parallel to one another, wherein: rolling elements (12a) disposed in a first plane (E1) have a radius and rolling elements (12b) disposed in a second plane (E2) have a radius.

Abstract: The invention concerns a chain pulley block with a chain wheel for positive-locking transmission of the lift force to the chain and a chain guide arranged in the region of the chain wheel, for guiding the chain, especially a round-link chain, on the chain wheel. In order to make it fast, easy and inexpensive to replace wearing parts, such as chain (3), chain wheel (4) and chain guide (2), it is proposed that the chain guide (2), the chain wheel (4) and the chain (3) be assembled into a structural unit (1), which is removably fastened to the chain pulley block (7).
