Two boys exploring a cave and one falls in. Our heros respond and deploy rope rescue gear and rescue techniques to successfully lower a medic to attend to the injured boy. They then raise the boy up out of the cave and transport him to an ambulance. Now whether this is or isn’t what a team would do, doesn’t matter. Whether someone agrees or disagrees with re-enactment is not pertinent. What I want to stress here is to HAVE A STRATEGIC PLAN that matches TALENTS and SKILLS.
A strategic plan is written document that points or directs a process for a given event. It needs to include hazards, goals and objectives. Strategic planning is also a growth strategy. Like any business, clarity leads to efficiency and efficiency is something we can confidently build from.
- Understand the History of the event.
- Who and or What are you dealing with?
- What is the Problem and Objective?
- Develop the Plan and divide the jobs… Doers and Overseers (do not mix)
- Summarize the Plan… Calls To Action
- Direct (measurable and completed)
- Transitional (moving forward)
- After event party… What? What did we learn and grow from?
For what was used…
For the purpose of lifting or moving heavy loads a block and tackle system consists of two or more pulleys connected by one common cord or rope that is threaded between the pulleys. As most know, pulleys are simply wheels on axles designed to assist or direct movement of the rope along the grooved circumference of the wheel. One pulley alone can be utilized to lift loads and apply forces to transmit power, but incorporating multiple pulleys into a system decreases the amount of applied force required to transmit the power to move the load.
A pulley, also known as a sheave or drum, most commonly has a groove on the wheel’s outside edge along the perimeter of the wheel between two flanges around the pulley’s circumference. The cord or rope is the drive element of the pulley or pulley system. When the rope in a pulley is pulled upon, the force applied to the rope compresses it against and into the V groove between the flanges of the pulley wheel creating sufficient friction to move the wheel, rotating the pulley wheel around its axle.
Multiple pulleys can be configured to form a block and tackle system for the purpose of providing a mechanical advantage to apply large forces in order to lift or move the heavy load more easily than with one pulley. Two pulleys together in a system form blocks. Blocks are arranged in such fashion that one moves with the load while the other is in a fixed position. The assembly of a set of two blocks with the rope threaded around the respective pulleys is called tackle. The rope threaded around the pulleys is referred to as reeving. The rope or cord that is reeved through the pulleys provides mechanical advantage. Mechanical advantage amplifies the force applied to the rope allowing for the moving or lifting of the load with less initial, original force. The end result is a system of pulleys that moves and lifts loads more easily while less force is applied when pulling upon the cord or rope.
