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.

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.

Diagonal reinforcement for floor formwork support structures, the support structure comprising height-adjustable props on which diagonal reinforcements are mounted, wherein each of the diagonal reinforcements comprises a projecting pivot close to the upper end thereof, or on the upper end itself, the free end of which pivot is deformed towards one side and can fit progressively into one of the holes in the prop on which the pivot is mounted by means of rotation, it being possible to detach the reinforcement simply by reproducing the insertion movement in reverse.

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.

A mover system that moves a work platform relative to a target object. The mover system includes a drive vehicle configured to be attached to the work platform. Sensors are attached to the work platform that detect a distance between the sensors and the target object. Signals from the sensors are used to determine an alignment angle used for the operation of the drive vehicle to move the work platform into alignment and spacing relative to the work object.

A method of constructing a structure in which an item is to be installed at an elevated height on the structure. Hoists are hung from the structure. A platform is moved from ground level and positioned at a first elevated position between ground level and the hoists. The platform is attached to the hoists at the first elevated position. After the platform has been attached to the hoists, the item is moved onto the platform. The item is lifted on the platform to a second elevated position for installation at the elevated height on the structure and the item is installed at the elevated height.

A scaffold system comprising a set of components adapted for assembly of a scaffold section. The components are at least two frame components, each having at least two vertical members separated by at least two interconnecting members, the at least two vertical members comprising a socket; two or more brace components adapted to span between and connect to the two side frame components; at least four corner pole components, each adapted to connect with the socket of a vertical member; and a plurality of support rail components adapted to span between two pole components.

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.

A buffering device for capping exposed ends of poles. The buffering device provides enhanced buffering against external impacts and a large surface area. The buffering device includes a head and a sleeve, wherein the head is of mushroom shape. The sleeve can receive an end portion of a pole.
