The construction industry ranks among the largest and most dangerous industries in the world. To promote worker safety, government regulations require use of fall protection equipment, such as railings, many of which are expensive, wasteful, and/or time consuming to use. Accordingly, the present inventor devised some alternatives. One exemplary system incorporates a dual post base plate configured for attachment to a concrete floor via a single concrete anchor bolt, instead of the multiple bolts used conventionally, thereby reducing assembly time and cost. Another embodiment includes a rolling cart assembly which stores the rails in a side-by-side vertical arrangement and the base plates in an interleaved sequence, promoting easy access during installation and inventory control during disassembly and storage. Additionally, some embodiments include four stacking posts that extend upward from the cart, enabling multiple carts to be stacked vertical on atop the other to save space on construction sites.

A safety system alerts individuals to the presence of a floor opening in a floor grid or work platform decking that is supporting the individuals. The safety system is a passive safety system that is operatively connected to a stationary first floor panel that is adjacent a second floor panel. The safety system is automatically operated to deploy a signal flag above the first floor panel (and activate an audio warning signal) when the second floor panel is removed, exposing a floor opening adjacent the first floor panel. The deployed signal flag alerts individuals on the floor grid or work platform decking to the presence of the floor opening.

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.

Provided is a device for covering a gap between temporary work platforms, which is capable of securely covering a gap between spaced temporary work platforms, thereby preventing a worker's foot from being caught in a gap or preventing an accident caused by dropping of work tools, building materials or the like through a gap, and which provides excellent convenience of use due to its structure capable of simply and easily covering a gap between the temporary work platforms, and which is easily installed or dismantled without any specific work tools or devices. The device includes a flat-plate-shaped cover plate, both lateral side portions of which are placed on the top surfaces of adjacent temporary work platforms in order to cover a gap formed between the temporary work platforms. The cover plate is provided at the bottom surface thereof with a coupling portion. The device further includes at least one separation-preventing unit configured to be coupled to the coupling portion of the cover plate in order to prevent the cover plate from being separated from the temporary work platforms.

A climbing device is proposed having at least one climbing rail for adjusting and/or climbing a scaffolding and/or a formwork and/or a platform, at least one climbing shoe being arranged on the climbing rail, at least one hydraulic cylinder comprising at least one drive piston, arranged in a cylinder housing, and having a hydraulic fluid being provided for raising the climbing shoe and/or the climbing rail and/or the scaffolding and/or the formwork and/or the platform, which at least partially avoids or at least reduces the disadvantages of the prior art. According to the invention this is achieved in that the hydraulic cylinder is embodied as a hydraulic unit, the hydraulic unit comprising at least one hydraulic tank for storing hydraulic fluid, an electric motor and a hydraulic pump driven by the electric motor for pressurizing the hydraulic fluid.

A safety device including a boom with a primary end and a secondary end, where: the primary end and secondary end are the opposite terminal ends of the boom; the primary end is configured to be, releasably or permanently, attached to a mounting which includes a mounting joint which is a hinge joint; the boom includes a base section, zero or one intermediate section and a load section connected together, in that order, by hinge joints, such that the safety device can extend from a mounting in a single plane, a movement plane, that lies parallel to the longitudinal axis of the boom, the primary end is coterminous with an exposed end, a first base end, of the load section; the load section includes a first load end and a second load end, where the first and second load ends are opposite terminal ends of the load section; the secondary end is coterminous with the second load end; and the second load end includes a connection point, where the connection point is configured to releasably attach a user to the boom via a device with fall arrest capabilities, such that the connection point does not slide lengthwise along the load section.

A scaffold that is quick and easy to assemble while still implementing safety measures. The scaffold can include end caps that resist or prevent users from falling off the ends of the scaffold. The end caps are quickly assembled to the scaffold with a removable rod and pin mechanism. Moreover, to prevent a user from falling off the front or back of the scaffold, a pole and a mid-rail connector can be connected to the scaffold across the front or back, respectively, between an upper barrier and a lower platform. The pole can be inserted through connectors that are coupled to the scaffold, and can also be connected to mid-rail brackets for additional structural stability.

One embodiment of the invention is a horizontal scaffold truss that has upper and lower horizontal scaffold members offset but fixedly joined with braces. Each upper and lower members have a connector positioned on each end of the respective lower and upper members, where at least one of the connectors is pivotally mounted on the respective lower or upper connector, and the connecters are engageable with an annular member positioned on a vertical scaffold member.

To address one or more of these and/or other needs or problems with the use of climbing aids in the construction industry, the present inventor devised, among other things, one or more exemplary systems, kits, methods, devices, assemblies, and/or components related to providing safe and efficient means for installing temporary walls in commercial building projects as well as for other situations where conventional ladders pose heightened risk of injury and death. One exemplary system includes a telescopic climbing mast having a minimal operational length in the range of at least 15 feet, extending between a base support and a ceiling interface configured to resist lateral movement of an upper end of the mast. An upper portion of the mast further includes a worker safety line tie-off point for connection to a retractable fall restraint line.
