Hinged safety gates and methods for controlling access to an elevated work surface are disclosed. The hinged safety gate can include a gate frame and a retainer assembly. The gate frame can have a distal upright member, an upper cross-arm, and a lower cross-arm. The upper cross-arm can have an upper cross-arm height (or vertical dimension), and the lower cross-arm can have a lower cross-arm height. The hinged safety gate can have a retainer assembly that is configured to be attached to a proximal end of the gate frame and to hingedly couple the gate frame to a stationary vertical surface, permitting the gate frame to swing between an open and a closed position. Some embodiments satisfy various spatial safety requirements with only two cross-arms. Some embodiments are horizontally adjustable in two different manners to accommodate a range of access area widths.

An adjustable support for use in shuttering formwork comprising a base member, a shuttering contact member, and a bracing member, wherein the base member, the shuttering contact member and the bracing member are engaged hingedly with one another. The bracing member is engaged securably with the shuttering contact member and the base member. The bracing member is adjustable, such that adjustment of the bracing member causes rotation of the shuttering contact member about the base member. Also disclosed is a method for supporting shuttering comprising providing one or more adjustable supports as described above, affixing the or each base member to a substantially static object, assembling the or each bracing member and the or each shuttering contact member as described above, adjusting the or each bracing member and attaching the or each shuttering to the or each shuttering contact member.

A case or support cradle (10) for a fall arrest device has a shape or configuration enabling rolling of the case or cradle (10) along an arcuate path. The rollable case or cradle (10) allows the fall arrest device received therein to smoothly follow a user's movements around a work site, thereby protecting the device from damage due to dragging or scraping along a floor surface.

A rough-in box used during the construction of buildings having poured concrete flooring, such as multi-story high-rise buildings. The rough-in box may be used to retain an opening in the floor through which plumbing and mechanical components may be installed after concrete has been poured around the device and hardens into a slab. The present invention also relates to a method comprising the steps of assembling the side walls of a box, placing a lid made of a material stronger than that of the side walls and capable of supporting a weight of 2,000 pounds, placing the box over a hole on the floor, and pouring concrete to form a floor around the box. The box will remain in place providing an accessible penetration through the flooring with space for plumbing connections and a flush surface with the floor over which pallet jacks and workers may travel without obstruction.

The invention relates to a side protector (3) for ceiling formwork (2). The ceiling formwork (2) comprises at least one formwork element (4) having a frame (5). The side protector (3) has a railing (11). Furthermore, the side protector (3) has a pivoting frame (10). The railing (11) is connected to the pivoting frame (10). The pivoting frame (10) can be connected indirectly or directly to the frame (5) from the bottom side of the ceiling formwork (2). The pivoting frame (10) can be pivoted from an installation position into an end position about an axis of rotation (A) in such a way that the ceiling formwork (2) is laterally secured by the railing (11). Furthermore, a ceiling formwork system (100), having at least one corresponding side protector (3) and ceiling formwork (2), is specified. In addition, a method for erecting such a side protector (3) is specified.

A perimeter protection system for protecting operators against lateral falling when installing formwork panels in a horizontal formwork system. According to one embodiment the perimeter protection system includes a perimeter protection structure configured for being fixed, in a working position, to the horizontal formwork system, and at least one auxiliary device configured for being fixed to the horizontal formwork system and for fixing the perimeter protection structure to the horizontal formwork system. The auxiliary device includes guiding means collaborating with a guide of the perimeter protection structure for positioning the perimeter protection structure in an initial assembly position. In the initial assembly position the structure is configured to be raised up to an intermediate position where it is permitted to swing until it is positioned in the working position.

The present system for fall restraint includes a mounting frame connected to a trigger mechanism and firing blocks, with a trigger cable extending through apertures in the mounting frame and trigger mechanism. Sudden movement by a user, such as a fall, actuates the trigger mechanism to trigger the firing blocks. The firing blocks are loaded with anchors and firing cartridges. Triggering the firing blocks causes the cartridges to fire, propelling the anchors into an anchoring surface, such as a roof. Because the user is connected to the trigger cable, once the anchors deploy the user is anchored to the roof and their fall arrested.

The invention relates to a safety harness device for catching a person if they fall, in particular in the case of construction activities, comprising at least one shoulder strap, which has a chest portion, a shoulder portion and a back portion, comprising a locking element for releasably attaching a safety rope, wherein the locking element can be transferred between a working position, in which the locking element is arranged on the back portion side of the shoulder strap, and a catch position, in which the locking element is arranged on the chest portion side of the shoulder strap.

In at least one embodiment, a lifeline includes a wire rope and a shock absorber. In some embodiments, the shock absorber includes a tubular body defining a lumen therethrough. The tubular body defines a longitudinal axis including curvature along its length.

Provided is a platform positioning system including a platform and an elevator, wherein a cabin of the elevator is movable along a wall segment of a building, wherein the platform positioning system further includes a first attachment mechanism for releasably attaching the platform to the cabin, wherein the motion of the cabin and the platform are coupled to each other when the platform is attached to the cabin, and a second attachment mechanism for releasably attaching the platform to the wall segment.
