Jiggers Are Compact 4:1 Pulley Systems and are The Rigger’s Future

By Lance Piatt / AZTEK ELITE, Blog, General Rigging, Pulleys & Mechanical Advantage / 5 Comments

Generally, these beauties are considered pre-rigged pulley systems used mainly for hauling, but can be very important in lowering heavy loads as well. The advantage of these systems is in their rapid deployment, and straightforward operation without advanced levels of training or expertise. They are low maintenance and high yield work horses and have been …

The Jigger… What is it? – A Rope Rescue Technician’s Best Friend

By Lance Piatt / Blog, Equipment

A jigger system is a mechanical advantage system that uses pulleys to increase the force applied to an object. It is typically used in rescue and rigging operations where multiple people are needed to apply force to an object, such as a stretcher or piece of equipment. The jigger system allows the load to be distributed evenly …

Rope Rescue Gear and Everything Between! Part 4 – Selecting a System Safety Factor

By Lance Piatt / Blog, Designing Your Processes, Mainline Systems and Operations, Mechanical Advantage

When it comes to ensuring safety, there are a number of factors that need to be taken into consideration. During training sessions, the safety standards could be lower than during rescue operations as trainees may not have the same level of experience and expertise. However, this does not mean that training sessions can be conducted …

Actual Mechanical Advantage – Rope Rescue Rigging Systems

By Lance Piatt / Blog, Mainline Systems and Operations, Mechanical Advantage

The T-method of analysis allows us to account for the friction in the pulleys and calculate a more accurate mechanical advantage. The efficiency of each pulley is calculated by measuring the difference between its theoretical output force, from our original system analysis, and its actual output force, determined experimentally. The efficiencies are then multiplied together …

Mainline Rescue Systems – A New Course

By Lance Piatt / Blog, Mainline Systems and Operations

Mainline Rescue Systems – A New Course An understanding of mechanical advantage systems — in raising and lower modes — is crucial to all rope rescue technicians. Dealing with Mass and Force is aspects of consequence if not considered during operations. Working with tensioned anchor systems, guying systems, high directionals, load positioning and litter movement …

Haul System Basics & Pulley Systems on Rope

By Lance Piatt / Blog, Mechanical Advantage, Principles of Learning / 3 Comments

Thank you Peak Rescue Institute Let’s begin with manual hauls. When you talk about manual hauls or mechanical advantage, you have to talk about work. Work is done when force moves an object. Well, what’s this thing called force? Force is simply a push or pull that causes an action. And in fact, force can …
