Mechanical Tools for Your Easier Work

In our daily life, there are many industries in which you may have to lift some heavy things. Under those circumstances, the applications of some basic technology can help you a lot. You are able to lift something that you can not carry with the help of some tools.

Pulley is one important mechanical tool. A pulley is a wheel with a grooved rim. A pulley mounted in a frame is called a block. A block containing a single pulley is called a single block; one with two pulleys a double block, and so forth. Two blocks properly threaded or "revved" with rope are called a block and tackle.

A single block offers no mechanical advantage to the lifter. You end up lifting the entire weight, and just changing the direction of pull. However, by adding another block to this arrangement and creating a "single and single" block and tackle, you can reduce the force needed to lift a load by half. Adding another pulley increases your mechanical advantage to 3:1. Place the block with the most pulleys at the top, to serve as the immobile or fixed block. This would enable you to lift a heavy load by applying less force. As more pulleys are added, the extra weight and length of rope needed may become a concern, even though making it possible to lift heavier loads.

Compact hand winches are designed for all-terrain vehicles and snowmobiles, offer another possibility for attaching to the haul line. Tie off the winch to a tree. Depending on your system, use the cable or rope supplied with the winch as your main haul line or attach the cable to a nonslip loop in the haul line and tie off the haul rope to the tree before releasing it from the winch. With a very low gear ratio, winches allow very heavy weights to be lifted with ease. Portable pullers are also important devices that can be attached to the main haul line and used to lift the load in the air.

The above mentioned devices can help you to lift heavy loads off the ground. They have good performances and functions. But you should be sure that the rest of the suspension system can handle the weight and give some advance thought to how to safely lower the weight.
