Systems, apparatus, and methods to deploy safety equipment from a drone are disclosed. An example apparatus includes a sensor to gather environmental data and an analyzer in communication with the sensor. In this example, the analyzer is to identify an anchor site based on the environmental data and produce an assessment of stability of the anchor site based on the environmental data and model data. The example apparatus also includes one or more actuators to deploy a securing device in response to the assessment of the analyzer indicating the anchor site is stable and to deploy the safety equipment.

A device for storing a rope for a descender includes the rope, a rope drum, and a dimensionally stable rope bag, wherein the rope has a diameter of less than or equal to 8 mm and is at least partially wound on the rope drum in such a way that a first end of the rope can be unwound from the rope drum, and wherein the rope drum is disposed in the rope bag in such a way that the first end of the rope can be led out of an opening) of the rope bag. Furthermore, an assembly includes a descender and the above-mentioned device, wherein the descender includes a centrifugal brake configured such that a rope passing through the descender can be slowed down in its motion, and wherein the rope of the device is passed through the descender.

In a descending apparatus for emergency escape, a first winding part around which a wire rope is wound and a second winding part positioned above the first winding part and rotating to allow the wire rope unwound from the first winding part to be re-wound therearound to generate braking power are configured on an inner side of a case, a decelerating device controlling a descending rate of the descending apparatus by reducing a rotation rate of the second winding part by the braking power generated according to rotation of the second winding part when the wire lope is unwound as the descending apparatus descends are configured on both sides of the first and second winding parts, and an operating lever adjusting a descending rate of the descending apparatus by controlling a rotation rate of the second winding part according to an operation of an escaper when descending using the descending apparatus is configured at an upper portion of the case, and a handle 46 is provided to allow the wire rope to be wound therearound to re-use the descending apparatus.

Since a structure of the descending apparatus is simplified, in case of an emergency, an escaper, without being panicked, may simply operate the descending apparatus to descend to the ground, and thus, an accident may be prevented. Also, when using the descending apparatus, the escaper may easily adjust a speed during descending and quickly operate such as adjust a speed, stop, and the like, during descending to cope with various dangerous situations that may occur during descending, and thus, safety of using the descending apparatus may be enhanced. In addition, after the descending apparatus is used, the unwound wire rope may be wound again, and the wound wire may not be unwound, whereby the descending apparatus may be used again.

A safety cable system for installation during building construction is provided and includes a first track mounted to a first structural element of a building, a first plurality of anchors slidably engageable with the first track, a second track mounted to a second structural element of a building, a second plurality of anchors slidably engageable with the second track, and a plurality of cables interconnecting the first plurality of anchors and the second plurality of anchors. The first plurality of anchors, the second plurality of anchors, and the plurality of cables are positionable vertically at a plurality of different heights above a floor of the building, or horizontally at a plurality of different positions above the floor. Also provided are stops for restricting movement of the first and second plurality of anchors, roller bearings that capture the plurality of anchors in the tracks and allow the anchors to slide with respect to the tracks, plates and associated mounting hardware for mounting the tracks, turnbuckles for tensioning the cables, and tie points for tying a netting between the tie points.

A hoisting apparatus or PPE for use at a manhole comprises a structure mountable to a surface, the manhole and/or a structure present in the vicinity of the manhole. The hoisting apparatus comprises a multi-angle bearing assembly mounted at one end of the structure that is adapted to have a rope or alike attached or anchored to a point of the structure distant to the multi-head bearing assembly to guide the rope when the rope extends in one of an available range of directions. The multi-angle bearing assembly comprises a ring assembly defining an opening adapted for the rope to go through, and a plurality of spools mounted to the ring assembly adapted to guide the rope in a path distant from the edge of the ring assembly in any if the direction of the rope of the range of available directions.
