An elevator cable management system is described to provide constraints on cable movements at a point between the top and bottom of an elevator track. The system may include a moving retainer bar with a cradle on top of an elevator car, and a fixed retainer bar that retains cables when the elevator car is above the fixed retainer bar.

An elevator shaft element, an elevator arrangement and a method of a construction time use elevator. The elevator shaft element comprises a frame module arranged for receiving an elevator car therein. The frame module is constructed from a transport and/or storage unit, comprising side walls, a bottom wall and a roof wall. The unit is arrangeable vertically such that said side walls, bottom wall and upper wall of the unit define an inner space of the elevator shaft. The side wall, the bottom wall or the upper wall of the transport and/or storage unit is opened at a length more than a floor height of a building for providing an opening for one or more landing doors, the opening having a first side-edge and a second side-edge parallel to longitudinal direction of the transport and/or storage unit. The elevator shaft element further comprises at least one stiffening beam arranged to be fixed to the opening and extending from the first side-edge to the second side-edge.

A containment unit that facilitates delivery of parcels using drones is provided. An example containment unit comprises an inner housing unit and an outer housing unit. The inner housing unit includes a first and second sidewall that are connected by an end piece and have a bottom opening in between. The inner housing unit is movable from a retracted position over a floor of the containment unit to an extended position, where a portion of the opening is extended beyond the floor. A parcel may be inserted into a volume of space within the inner housing unit from below through the opening and pulled into the containment unit by the end piece when the inner housing unit is retracted. The containment unit can be used as part of a drone delivery system that can also include an elevated delivery platform, a computer application, or any combination of these aspects.

An all-weather maintenance system for an offshore wind turbine maintenance program includes a maintenance capsule for transporting tools, parts and maintenance personnel to and from respective wind turbine towers, a maintenance vessel with a capsule support apparatus for transporting capsules supported on board by the capsule support apparatus to and from respective wind turbine towers, and a crane assembly with a trolley for transporting capsules between the respective wind turbine towers and the maintenance vessel.

A grommet is at least partially comprised of a clear, rigid material is disclosed. The body of the grommet tapers from a proximal end to a distal end, allowing the grommet to be guided into a hole in a post of a handrail system. The interior of the body includes an longitudinal cannulation open to the exterior of the grommet via a helical cut in the surface, allowing for a wire rope to pass through. The grommet can be installed whether or not a wire rope has previously been passed through a railing post.
