Use a come along by extending the cable to its full length, attaching one end to a stationary object and the other to the load. Move the handle back and forth until the device rewinds the cable on the central wheel. To continue to move the load, extend the cable again and move the stationary end to a new anchor point.Continue Reading
A come along is a hand winch that allows a human to move a heavy load using a system of levers, pulleys and cables. Farmers often use the device to tighten wire when building fences. In the garden, it is useful for heavier jobs such as removing tree roots. The device allows a user to exert 2 to 10 tons of force on the object being moved.
The come along uses a lever and a ratcheting wheel to rewind the cable. The cable attaches to the come along frame and to the ratcheting wheel with a pulley at the end that attaches to the load. This arrangement creates a movable pulley, giving the user a mechanical advantage by dividing the force to move the load by one-half. The handle of the come along is a second-class lever, with the bolt in the center of the wheel acting as the fulcrum and placing the load between the fulcrum and the force, at the edge of the wheel. The length of the lever determines the amount of additional mechanical advantages it provides.Learn more about Tools
There are several different types of CASE skid steer models that have different specifications, such as the SR130 with a 1,300-lb operating load and SR240 with a 2,400-lb operating load. Smaller units, such as the SR130 are used for less intensive commercial projects, however all CASE skid steers are available with a 3-year warranty.Full Answer >
To read a crane load chart, first determine the weight of the load the crane has to lift. Next, calculate the distance the load needs to move. Measure this distance starting from the center pin of the crane to the center of the load.Full Answer >
A double pulley system, also known as a block and tackle, provides a mechanical advantage that allows for increased lifting force to be applied when pulling a rope or cable. By dividing weight between multiple pulleys, heavier objects may be lifted with less overall effort.Full Answer >
To change the belts on an Ariens two-stage snow blower, remove the belt cover, disconnect the chute crank and deflector cable, remove the frame housing, belt finger and auger belts, and remove the old drive belt. Then, loop the new drive belt around the pulleys and reconnect the housing, cute crank, deflector cable and belt cover.Full Answer >
