An multi-position ladder is disclosed that includes an adjustable top cap that provides a tool or material tool tray when the ladder is in a stepladder position and provides a step when the ladder is in an extension ladder position is disclosed. The top cap generally comprises a rigid frame extending between the adjustable hinges of the multi-position ladder with a tool or utility tray and a step surface on opposing sides. The tool tray is parallel to the ladder rungs when the ladder is in a stepladder position, and the step surface provides a generally planar surface parallel the rungs when the ladder is in an extension position. The rigid frame of the top cap adds strength to the adjustment hinge and to the multi-position ladder. Embodiments allow for 12-inch hinge spacing, adding one foot reach in the extension position and six inch reach to the stepladder.

A movable storage assembly has first and second mobile storage units that are selectively movable towards and away from one another and are equipped with a deployable and retractable (or installable and removable) platform to facilitate access to upper regions of the storage units. The platform is movably coupled to one of the mobile storage units and can be repositioned between a deployed or installed position in which the platform interlocks the first storage unit to the second storage forming an elevated walking or standing surface therebetween, and a retracted or removed position in which the platform is partially disconnected to allow the first mobile storage unit to move independently and into close proximity with the second mobile storage unit.

A movable storage assembly includes a pair of upright frame pieces joined together by a lateral rail. The rail's opposite ends each include a T-shaped upper tab having upward and downward extending portions, and a lower tab with downwardly extending portion. The upper and lower tabs are simultaneously insertable into upper and lower openings along the uprights, and then lowerable so that the downward portions of the upper and lower tabs secure the rail to the uprights. Upward movement of the rail causes the upward portions of the upper tabs of engage the uprights above the upper openings, preventing removal of the upper tabs from the uprights. Optionally, part of a platform is supportable at the rail and cooperates with the upper tabs to prevent removal of the lateral rail from the uprights, even if the downwardly extending portions of the tabs are disengaged from the uprights.

A cage for surrounding a section of a work area of the top of rolling stock includes an inboard side, an outboard side, a front end section and a back end section. The inboard side of the cage is attached to an associated deployment apparatus. Each of the two sides can define a pair of fence notches to slide over the rails surrounding the work area. Each of the two end sections can define an inboard notch and a center notch. Some embodiments of the end sections can define an outboard notch that includes a self-adjusting straddle. The cage can be provided as part of a portable fall protection device that includes a telescoping positioning mechanism.

An access platform system for enabling access to and from ground-based structures, vehicles, and mobile equipment. The system has a main frame with walls that is attached to or juxtaposed with the ground-based structures, vehicles, and mobile equipment; a vertical platform displacement assembly attached to the main frame; and a folding steps assembly. The vertical displacement mechanism has left and right intermediate carriage assemblies, and left and right lift cylinders with a multi-stage apparatus for influencing the stroke of the lift cylinders. In one embodiment, the folding steps assembly has an electromechanical means for folding and unfolding the steps.

A portable multi-use platform that is capable of providing 360 degree views for multiple persons safely and securely without interfering with each individuals comfort space. The platform can be easily set up and taken down and transported to different locations using a detachable wheeled frame assembly. The applications of this platform are not limited solely to hunting but can be used in numerous activities such as “zip-line” type sports, photography and video applications, utility pole climbing professions, as well as military and police operations. This platform solves the problem of partial views, limited occupants, and the transportation over terrain to and from site. It also addresses the issue of attaching to a plurality of various tree sizes with a sliding floor attachment system as well as a possible problem of tree lean and leveling with the use of a sliding “biter” system.
