The invention relates to the field of elevator equipment manufacturing technology, and particularly relates to a vertical-lifting elevator anti-falling protection device. The reasons of elevator falling mainly lie in the drop or breakage of a steel wire rope, overload operation, speed measurement and limiting device and equipment failure, and the elevator falling rarely happens. In order to overcome the shortcomings of the prior art, the invention provides a vertical-lifting elevator anti-falling protection device independent from the existing safety guarantee system. The device provided by the invention consists of a brake box embedded into a shaft wall and a fixing rack fixed on the side surface of a car. When an elevator falls, a brake instruction is given manually or by a speed sensor, an electromagnet in the brake box adsorbs a movable slider so that the teeth of the movable slider are meshed with the teeth of the fixing rack, the teeth of the fixing rack collide with the teeth of the movable slider repeatedly, and the impact force of the falling car is absorbed by a spring set; and when the kinetic energy is completely absorbed and the speed approaches to zero, the resistance against the brake box is greater than the total gravity of the car, thus a soft landing process of the car is formed to realize the brake of the car.

An anchoring system includes an anchor member to anchor the lifeline and at least one extending unit to extend the anchor member out to a working position beyond (horizontally) and above (vertically) an edge to provide for an overhead anchoring point. The anchoring system preferably further includes a support to which the extending unit is attached. The support immobilizes the overhead anchoring system so that the anchor member remains at the working position (even in the case of a fall by the worker). A method of anchoring a fall protection lifeline for use by a worker working at or beyond an edge includes the steps: elevating an anchor member to position the lifeline above the head of a worker and supporting the anchor member at the working position. The method can also include the step of extending the anchor member to a working position horizontally beyond and above the edge.

A skylight fall protection safety panel formed from a single sheet of metal having a predetermined surface area A1 and a plurality of apertures are punched out of at least one central perimeter surface area A3. A2 is as great as or greater than 0.60A1. The shape of the apertures can take many different forms but they would have a greatest width D1 that is less than 2.0 inches. The central perforated portion has a sufficient number of apertures of a sufficient size that 50 percent of A2 is open to pass light therethrough. The sheet metal safety panel would be secured under an existing fiberglass skylight panel. The sheet panel can also be corrugated to match translucent skylight panels that are corrugated. The sheet metal panel can also be inserted into a mold or cast with a top layer of resin material and a bottom layer of resin material and also having the central perforated portion apertures filled with resin. This assembled structure functions both as a skylight panel and also as a fall protection safety panel that will prevent workers stepping on the top of the assembled structure from falling therethrough and injuring themselves.
