A system and method are provided for employing man-portable unitary platform system segments, particularly as components of integrated castle defense systems. A lightweight modular and mobile system of integrated platform segments is provided to facilitate users integrating flexible platform configurations secured to existing wall structures to support myriad user tasks. Individual platform system segments can be autonomously employed, or can be linked together after being quickly attached to a wall, a structure, or another supporting surface by two users in minimal time. In law enforcement, security, military and/or paramilitary employment scenarios, individual platform system segments are emplaced, and linked together, to provide a unitary defensible position in a matter of minutes. An overall platform structure of a plurality of individual man-portable platform system segments provides operational and employment flexibility that was previously unattainable to bolster or boost defenses of a particular position against increasing, and increasingly agile, threats.

A telescopically extendable and collapsible ladder assembly includes a top ladder section, a bottom ladder section, and one or more intermediate ladder sections. The assembly may include sliding automatic release actuators, having a slanted actuating surface for interaction with actuator surfaces of spacers provided at each end of a rung of an adjacent ladder section, such that, when a rung is moved towards the rung of an adjacent lower ladder section, the activation surfaces of the spacers push the release actuators into an unlocking position and subsequently position the rung at an anti-finger pinching distance. The top rung of the bottom ladder section may be provided with a centrally arranged grip element that forms a housing for manually operable release actuators provided at the bottom side of the rung.

A portable workbench assembly includes a table. Objects may be positioned on the table thereby facilitating the objects to be accessible. A handle is hingedly coupled to the table thereby facilitating the table to be carried. A pair of stands is provided and each of the stands is hingedly coupled to the table. Each of the stands is selectively positioned in a deployed position to abut a support surface. Each of the stands is selectively positioned in a stored position.

A rapid release and rapid install latching member for use with ladder cages to couple the cage rings is provided wherein the latching members are capable of retaining the cage ring connecting members thereon without the use of external fasteners. The latching members are designed such that they may be removed from or installed on the ladder cage while the ladder cage is installed at the work site or otherwise for quick and easy repair or replacement. An exemplary ladder cage contains a plurality of ring members having a plurality of latching members interspaced around the circumference thereof, with adjacent ring members being coupled to each other through the interaction of cage ring connecting members with the latching members.

A wind turbine blade is provided, including a hollow blade body with a blade root and a base plate arranged at a root-side end section of the blade, which base plate includes a manhole through which the interior of the blade is accessible, wherein the base plate is provided with mounting means arranged at the or adjacent to the manhole and adapted to directly or indirectly mount at least one ladder to the base plate.
