This Promotional book is destintened be part of a more indepth book called, Ropes, Pulleys, Rigging Systems, and Avoiding Dangerous Resultants (3rd Ed); which has over 500 pages. This book will be the foundation for the "Pulleys section." This book has over 150 pages, and more than 100 pictures, charts, diagrams, and drawings to help communicate, and build a good foundation and understanding about pulleys and their many uses. It includes real life examples of ways pulleys function and aid us while working and at play, including ways to setup various pulley systems, and their advantages and dis-advantages. How to figure out "What the Mechanical Pulley advantage different systems create." I go over simple pulley systems like "block and tackle" systems. Then I discuss Complex systems and how they work. From there I move onto Compound systems and how the various system come together to accomplish various tasks.
I show pictures of actual situations where pulleys are used at work and at play. Including many related things like how mechanical rope grabs (used in a system or as a progress capture device, effect the rope, counterbalance systems, and many more things related to pulleys and the various connectors, ropes, and other gear. This book begins with some advanced basics, and then addresses many skills and situations used in rescue by professionals, and skilled workers, by people involved in Sailing, Search and Rescue, Confined Space work, Firefighters, EMS Personnel, FEMA Personnel, Construction Workers, Adventure Professionals and Recreationalists, anyone who works with ropes, and pulleys. It is explains the difference between simple, complex, and compound pulley systems. How a pulley system may overload a component in such a way that it becomes a disadvantage, and may cause an anchor or other component to fail. I also address safety, situational awareness, and how and why a "Principle based approach is best. It includes original sayings to help you remember various goals when assembling systems, like "Maximum efficiency and simplicity, with a minimum amount of effort and equipment, while maintaining a low risk exposure (Safety Picture) or "Ways, Means, Methods, and Techniques change, Principles never do." Principles provide a constant which allows us to build systems with predictable outcomes.
With over 40 years of training, study, and experience in teaching, rescuing, working, testing and fiddling with pulleys and rigging gear, I believe I have some insights not found in any other text on the subject. One thing I have decided to do to keep this valuable book in a price range everyone can afford is use grayscale printing on the interior pictures, and used black and white printing for clarity on many of the diagrams. Thanks for your interest. Douglas S. Hansen.
