Abstract: A method for exchanging a power source in a load handling device operative on a grid framework structure, the grid framework structure including a track system extending in a substantially horizontal plane and forming a grid pattern containing a plurality of grid cells; a plurality of upright columns supporting the track system; and a plurality of stacks of storage containers arranged in a plurality of storage columns located below the track system. The method includes removing a first power source from the load handling device; inserting the first power source into a first storage container in a first grid cell; removing a second power source from a second storage container in a second grid cell; and inserting the second power source into the load handling device.

Abstract: A load handling device for lifting and moving containers arranged in stacks in a storage structure. The storage structure includes a track structure arranged in a grid pattern which defines a plurality of grid cells above the stacks of containers. The load handling device includes: a driving assembly configured to horizontally move the load handling device on the track structure; a lifting mechanism configured to lift a container from a stack; a power source; and an externally accessible power source compartment configured to electrically couple to the power source. The power source compartment is configured to removably receive the power source in a vertical direction.

Abstract: A load handling device is disclosed for lifting and moving one or more containers stacked in a storage system having a grid framework structure supporting a pathway arranged in a grid pattern above stacks 1of containers, the load handling device including a vehicle body housing a driving; a lifting device including a lifting drive assembly and a grabber, wherein the lifting drive assembly and/or the driving mechanism includes at least one motor forming an electrical load; a rechargeable energy storage for providing energy to power the electrical load; and a charging system including a first part for charging the rechargeable energy storage including a charge receiving element on the vehicle body, and a second part for delivering energy to the electrical load; wherein the second part includes a DC/DC converter to supply a predetermined DC voltage across the electrical load.

Abstract: A turboengine blading member having a platform and an airfoil. The airfoil includes a pressure side, a suction side, a leading edge and a trailing edge. An upstream region of the airfoil extends from the leading edge in a direction towards the trailing edge and a downstream region of the airfoil extends from the trailing edge in a direction towards the leading edge. The airfoil is connected to the platform in the upstream region, and is disconnected from the platform in the downstream region, such that the downstream region cantilevers from the upstream region, whereby a gap is formed between a cross sectional face of the airfoil in the downstream region and an opposed surface of the platform facing the cross sectional face. A sealing member is provided inside airfoil and platform pockets and bridges the gap.
