Examples of rope and pulley systems illustrating mechanical advantage. Consider lifting a weight with rope and pulleys. A rope looped through a pulley attached to a fixed spot, e.g. a barn roof rafter, and attached to the weight is called a single pulley. It has a mechanical advantage (MA) = 1 (assuming frictionless bearings in the pulley ...
The winch may be mounted to a vehicle, set into the ground by stakes, or tied to a tree. The cable may also be run through pulleys mounted offshore so that it pulls the person away from where the winch is located, and multiple pulleys may be used to multiply the force applied by a small but high revving motor instead of using a transmission.
The first of these systems used mechanical clutches between luffing and hoist drums, giving simplicity and a "near level" result. [ 5 ] Later systems have used modern electronic controls and quickly reversible motors with good slow-speed control to the hoist winch motors, so as to give a positioning accuracy of inches.
Pulley in oil derrick A hoist using the compound pulley system yielding an advantage of 4. The single fixed pulley is installed on the hoist. The two movable pulleys (joined) are attached to the hook. One end of the rope is attached to the crane frame, another to the winch.
The Unimog 411 was not a completely new development, rather Daimler-Benz derived the 411 series from the predecessor 401 and 402 series. In the 1950s, the Unimog design department under the leadership of Heinrich Rößler took a wait-and-see approach to new developments, even though consideration was given to offering the Unimog 411 with a 40 hp (29.5 kW) diesel engine and an 80 hp (59 kW ...
The stick is inserted into the loop and twisted, tightening the rope and pulling the two points toward each other. It is commonly used to move a heavy object such as a pipe or a post a short distance. It can be an effective device for pulling cars or cattle out of mud. [13] A Spanish windlass is sometimes used to tighten a tourniquet or a ...
