20080217825 | Magnetic Clamp - A magnetic clamp ( | 09-11-2008 |
20090295055 | ADAPTER FOR A MAGNETIC CLAMP - An adapter ( | 12-03-2009 |
20100013134 | Magnetic clamp assembly - A magnetic clamp assembly includes a magnetic clamp housing. The housing has a front face and a pair of opposes sides. A restraining arrangement comprises a restraining formation projecting outwardly from each side of the housing parallel to the front face. An adapter is mountable to the housing to bear against the front face. The adapter includes an engaging arrangement which engages the restraining arrangement when the adapter is mounted to the housing to restrain pivoting movement of the adapter relative to the housing. | 01-21-2010 |
20100213657 | Magnetic clamp - A magnetic clamp has a housing, the housing defining a base for resting on a work surface. An adjustable friction reducing arrangement is associated with the base of the housing. The friction reducing arrangement is movable relative to the base between a first position in which the friction reducing arrangement reduces an area of contact between the base of the housing and the work surface and a second position in which the area of contact between the base of the housing and the work surface is increased. | 08-26-2010 |
20120193510 | Concrete Sideform System - A concrete side form system suitable for factory casting or site casting concrete. The side form includes a substantially rigid longitudinally extending wall. The wall has a first face to define the edge profile of a concrete panel poured onto a casting bed bounded by the wall and a second face opposite the first face having formation to enable the wall to be secured to the casting bed. The wall includes a longitudinally extending frame having formation along at least one of its edges to removably receive a removable longitudinal insert to provide a shape along an edge of the concrete panel. The removable inserts provide the system with the ability to simply, easily and cost effectively change the edge profile of concrete poured against the side form. | 08-02-2012 |

20120240483 | CHAIR FOR A CONCRETE LIFTING ANCHOR - A chair for supporting an edgelift anchor for use in lifting a concrete component, said anchor comprising a head portion engagable with a clutch of a lifting system, and a body portion for embedment with the concrete component, wherein the chair has surfaces configured for supporting the edgelift anchor relative to a casting surface during casting of the concrete component. | 09-27-2012 |
20120279145 | ANCHOR FOR LIFTING A CONCRETE COMPONENT - An anchor for use in lifting a concrete component, said anchor comprising a single length of wire bent to form a head engagable with a clutch of a lifting system, and a body portion for embedment with the concrete component, wherein the wire is bent such that opposed legs of the body portion extend in a plane substantially perpendicular to a plane of the head portion. | 11-08-2012 |
20120304554 | COLLAR FOR A CONCRETE LIFTING ANCHOR - A collar for a concrete component lifting anchor including an attachment portion for attaching the collar to the lifting anchor, and an abutment portion adapted to provide a clutch abutment surface for limiting rotation of a clutch relative to the lifting anchor. | 12-06-2012 |
20130091785 | CONCRETE LIFTING ANCHORS - A shear bar for an edge lift anchor for a concrete panel, the shear bar being a bar shaped to provide a central portion to engage an upper edge of the lifting anchor when installed in the panel and legs inclining downwardly from each end of the central portion, the underside of each leg being profiled to lock into the surrounding concrete, the profiling being formed by a series of longitudinally spaced formations each of generally saw-toothed shape with a leading edge of each formation facing towards the central portion such that on application of shear load to the shear bar the leg will lock into the concrete with a generally compressive loading being applied to the concrete in the zone between the two legs. | 04-18-2013 |
20130097945 | CONCRETE LIFTING ANCHORS - A shear bar for an edge lift anchor for a concrete panel, the shear bar being a bar of rectangular cross-section shaped to engage an upper edge of the lifting anchor when installed in the panel, the bar having opposed large area faces and opposed smaller area faces and the bar being so shaped that when engaged with the upper edge of the lifting anchor one of its opposed large area faces will face towards the upper surface of the panel in the casting configuration of the panel. | 04-25-2013 |
20130119686 | CONCRETE LIFTING ANCHORS - A tension bar for an edge lift anchor for a concrete panel, the tension bar being shaped to provide a central portion to lie adjacent a head portion of the anchor and legs extending from each end of the central portion, an inner side of each leg being profiled to lock into the surrounding concrete, the profiling being formed by a series of longitudinally spaced formations each of generally saw-toothed shape with a leading edge of each formation facing towards the head portion such that on application of tensile load to the tension bar, the leg will lock into the concrete with a generally compressive loading being applied to the concrete in the zone between the two legs. | 05-16-2013 |
20130139451 | CONCRETE LIFTING ANCHORS - An edge lift anchor for a concrete product, the anchor having a head portion for coupling to lifting equipment and an anchoring portion, and a separate member mounted on the anchor and having integral legs extending to each side of the anchoring portion to increase the lifting capacity of the anchor. Alternatively or in addition, the separate member may provide a mounting for a tension bar to increase the lifting capacity. The invention also provides a support chair for retaining the edge lift anchor, together with an associated shear bar and tension bar if present. | 06-06-2013 |
