## Mastering Challenges: Moving Around Problems with Expert Techniques

In the world of rigging, passing knots through a system is a crucial skill that parallels the challenges we face in life. Instead of pushing through problems, mastering the art of maneuvering around them can lead to more effective and innovative solutions. This blog will explore how knot passing techniques can be applied as an […]

## Floating the Litter Using an A-Frame and Gin Pole Trackline

In a concerted effort to advance their technical rescue capabilities, the El Dorado County Sheriff’s Search and Rescue Unit (EDSAR) sought the expertise of Rigging Lab Academy. This collaboration was aimed at hosting a comprehensive workshop tailored to refine and elevate the team’s operational efficiency and proficiency in critical areas. The workshop was designed to

## Force Multipliers and The Fundamentals of Mechanics

Force Multipliers To understand rigging is to understand at least some aspects of trigonometry and vector physics. The knowledge of angles, components, and resultants is synonymous with quality rope rigging. To study vectors is to study the physical qualities of force that has both direction and magnitude. There are two important distinctions we make in

## Efficiency Unveiled: Understanding the Mechanics of Rescue Pulleys

Q: What makes a one pulley more efficient than another? There are a couple of key factors that affect the efficiency of a rescue pulley. The diameter of the sheave (the wheel in a pulley system that supports the rope) can make a difference – the smaller the diameter, the more bending of the fibers

## Unlocking Efficiency and Safety: The CAPTO and CLUTCH Mechanical Advantage System

Welcome to a new era in rope access and rescue operations, where innovation meets simplicity. In the world of technical rope work, the challenges of complexity, safety concerns, and limited versatility have met their match. Introducing CAPTO and CLUTCH – a dynamic duo designed to transform the way technicians approach their work. The following is

## Mastering the Art of Mainline Rescue and Rigging: A Comprehensive Guide

Mainline rescue and rigging systems encompass a comprehensive set of principles and techniques crucial for safely and effectively performing various forms of rescue and rigging operations. These systems are essential in scenarios like technical rescue, wilderness rescue, and industrial rigging, where precision and safety are paramount. Below is a synoptic overview of the key aspects

## Mastering Rigging Fundamentals: Forces, Mechanical Advantage, and Moving Systems

Rigging plays a pivotal role in the world of rescue operations, where the ability to analyze and manage forces effectively can make the difference between a successful mission and a potential disaster. In this blog, we will delve into three fundamental aspects of rigging: understanding the forces at play, harnessing mechanical advantage with pulley systems,

## English Reeve: Control Side & Carriage System Highline Systems

We’re back here at the lab, and this is a continuation of what we’ve done, the past couple of days with high lines. In quick review, We had, and we built the track line, and we had the control line for our basic high line system. Now what we’ve added to it is a third

## The New Harken Industrial Wingman

The Harkin Wingman is a compact haul kit that offers versatility, functioning as either a four-to-one or a five-to-one kit depending on how you position the load. You’ll notice significant distinctions when comparing the Wingman to other mini haul kits available on the market, with one notable feature being its exceptional compactness. We’ve engineered this

## 9 Ways To Quickly Get A Hold of the 3 Types of Mechanical Advantage Systems

Get More Done With Less… and remove the mystery out of “the theory” of Mechanical Advantage Systems. Mechanical Advantage Systems ~ arguably is the “bulwark” of rope rescue… giving strong support, encouragement and leadership to those in need. Wait!  Doesn’t “bulwark” have to do with wall like structures raised for defense? Like a seawall?  Sort
