A capstan winch uses a mechanically powered rotating cylinder, called a capstan, to apply pulling force through a rope. When the rope is looped around the rotating capstan and tightened, friction between the rope and capstan allows the winch to apply force to pull a load. A typical capstan winch is shown in Figure 1 below. (more…)
As an experienced safety consultant, I have investigated many serious injuries and deaths at construction sites over the past 39 years. The United States Department of Labor reports that the fatal injury rate for the construction industry is highest of all industries in the nation. Out of 4,386 worker fatalities in private industry in calendar year 2014, 899 or 20.5% were in construction i.e., one in five worker deaths were in construction. (more…)
As an experienced safety consultant, I’m called on to investigate a wide range of premises liability incidents. One common premises liability incident that often results in serious injury is a fall on a handicap ramp. There are at least four types of handicap ramps – flare side, parallel, returned curb and built-up. (more…)
In our last post on 3D scanning, we introduced Warren’s new Faro Focus X 330 three dimensional scanner. To recap, the Faro scanner combines three dimensional laser measurement with automated photography to capture 360-degree data from the real world. Potential applications include vehicle accident scenes and damaged vehicles, structural collapses, fire scenes, flood damage scenes, and machinery and equipment analysis, among others. In this post, we will highlight some of the outputs that can be created from the detailed data captured by the scanner. (more…)

We at Warren are pleased to announce our recent purchase of a Faro Focus X 330 three dimensional scanner with FARO Scene image processing software. The scanner takes up to 976,000 data points per second and can scan objects at distances to 1000 feet. The scanner forms a point cloud of millions of data points while also capturing 360 degree panoramic photographs. By combining a series of scans, a three dimensional representation can be created that enables precise measurements, animations, and demonstrations. The scanner can capture imagery indoors, outdoors, and even in darkness. (more…)
As an experienced safety consultant, I have investigated many incidents in my career in which a worker “falls through an opening.” The majority of these incidents have occurred at construction sites and most resulted in serious injury or death. (more…)
