- tor equipped with guide rails, ratchets, spring, platform and hoisting machinery. Otis had the hoist fully loaded with freight. As a crowd gathered, he climbed on board and ordered the platform raised to full height. The hoisting rope was cut with an axe. The crowd gasped. But before the platform could fall, the safety spring locked the lift in

- Hoist (device) A hoist is a device used for lifting or lowering a load by means of a drum or lift-wheel around which rope or chain wraps. It may be manually operated, electrically or pneumatically driven and may use chain, fiber or wire rope as its lifting medium. The load is attached to the hoist by means of a lifting hook.

Levers www.picgifs.com/graphics/b. /brooms/graphics-brooms-625707.gif. A lever is a machine made of a bar or rod (called an arm) which turns on a point called a fulcrum. A force (or effort) is used to move an object (or load). You can use a lever either to make it easier to move the load or to make the load move faster.

Simple machine A simple machine is a mechanical device that changes the direction or magnitude of a force. In general, they can be defined as the simplest mechanisms that use mechanical advantage to multiply force. Usually the term refers to the six classical simple machines which were defined by Renaissance scientists: Lever Wheel and axle Pulley Inclined plane Wedge Screw A simple machine uses a single applied force to do work against a single load force. Ignoring friction losses, the work done on the load i

- Wheel and axle. A second variation of the lever is the simple machine known as a wheel and axle. A wheel and axle consists of two circular pieces of different sizes attached to each other. The larger circular piece is the wheel in the system, and the smaller circular piece is the axle.

- Differential pulley. A differential pulley, also called Weston differential pulley, sometimes chain hoist or colloquially chain fall, is used to manually lift very heavy objects like car engines. It is operated by pulling upon the slack section of a continuous chain that wraps around pulleys.

Loader (equipment) A loader is a type of tractor, usually wheeled, sometimes on tracks, that has a front-mounted square wide bucket connected to the end of two booms (arms) to scoop up loose material from the ground, such as dirt, sand or gravel, and move it from one place to another without pushing the material across the ground.

- In second class levers the load is between the effort (force) and the fulcrum. A common example is a wheelbarrow where the effort moves a large distance to lift a heavy load, with the axle and wheel as the fulcrum. In a second class lever the effort moves over a large distance to raise the load a small distance.

Loader (equipment) A swing loader is a rigid frame loader with a swinging boom. The boom can swing 180 degrees or more. Swingloaders are primarily used by the railroad industry to lay rail. Like other loaders many attachments can be attached to the boom such as magnets, forks, and buckets.

Freer Elevator Sklar's® Freer Elevator is an orthopedic instrument that can be used as a multipurpose tool in many procedures, although it is primarily used for blunt debulking and lifting periosteum from bones in confined areas. This double-ended instrument typically has a rounded handle with two slightly curved, tear-drop tips.

- A pulley makes work easier by redirecting and amplifying force. It helps reverse the direction of an individual’s lifting force. As a user pulls a rope down, the pulley lifts the weight up. When two ropes and wheels are used, a pulley reduces the effort needed to lift a weight by half.

Windlass The windlass is an apparatus for moving heavy weights. Typically, a windlass consists of a horizontal cylinder (barrel), which is rotated by the turn of a crank or belt. A winch is affixed to one or both ends, and a cable or rope is wound around the winch, pulling a weight attached to the opposite end. A windlass would be constructed above a shaft which allowed heavy buckets to be hauled up to the surface. 2  This process would be used until the shaft got below 40 metres deep when the windlass would be replaced by a 'whip' or a 'whim' .

Pulley In a pulley system, one end of the rope is attached to the load and the other end is pulled in order to move or lift the load. A single pulley has only one wheel. The pulley makes the task of lifting a load more convenient since it is easier to pull a rope down than it is to lift a weight up.

Physics Homework Questions: How does a pulley make your work easier? A : reducing the effort applied. B : converting linear to circular motion. C : reducing the load to be lifted. D : by increasing the strength of the rope. A pully is simply a circular lever. The same amount of work is required, but you exchange one unit for another. To lift 10 pounds one foot requires 10 foot-pounds of energy. Using a pulley system, you may only have to lift the apparent weight of 1 pound, but you'd have to pull 10 times more rope.

Pulley The pulley is usually used in sets of two or more to gain a higher velocity ratio and mechanical advantage. Two sets of pulleys are used, one fixed and one moving. The pulleys are mounted, usually side by side, in a block or frame and the apparatus of pulleys and ropes is generally called the tackle. The whole system or machine is known as a block and tackle.

Water wheel A water wheel is a machine for converting the energy of free-flowing or falling water into useful forms of power, often in a watermill. A water wheel consists of a large wooden or metal wheel, with a number of blades or buckets arranged on the outside rim forming the driving surface.ost water wheels in the United Kingdom and the United States are (or were) vertical wheels rotating about a horizontal axle, but in the Scottish highlands and parts of southern Europe mills often had a horizontal wheel (with a vertical axle).
