Everyone must of heard of a Crane at some point in their life and know what one is... well how about a Crawler Crane? These machines are variations on the existing Crane and actually movable by people in the same way you would drive a vehicle. Standard overhead lifting machinery are stationery systems, that is where these variations differ. The Lifting Equipment is mounted upon (what is known as a Crawler), the crawler is tank like machinery with a different mount. They consist of multiple wheels enclosed in a huge tread (just like the mechanism used to drive a tank, they do not have a left and right function and in order to turn either the left or right tread turns whilst the other remains stationery.
These are very powerful and important forms of machinery in the construction industry; they are a lot more versatile than standard cranes and of course have the advantage of mobility.
It is not usual for these to be purchased when needed due to cost; instead special companies own these machines and hire them out to companies. If you are looking into getting one of these, have a look online and you will find lots of companies that offer them for Hire.Depending on the application you require them for you may not need a full size Crawler, in this instance Mini Crawlers are available and can also be hired out (normally at a low cost then the standard version). They are manufactured in many different sizes and are capable of lifting different weights.
