In the world of moving multiple or heavy objects we make use of many types of equipment. The most common used object is the sack truck. It is a simple thing with two wheels and it comes mostly in an L form. It is used mostly to move multiple smaller objects at the same time but can also be used to move one big object.

These objects are preferred to wheel barrows as they tend to be more versatile. Wheel barrows are better to use for moving things such as sand which can mold to the barrows shape. A dollie however is more ideal when moving more solid objects.

What makes a dollie more useful than a barrow is also its ability to change the gradient with which it can be moved. A sack truck for instance cannot be easily used when going up stairs. A dollie on the other hand can easily be pulled up a staircase.

Dollies are also useful when one needs to pack them away into small spaces when they are not being used. Dollies can most of the time be folded up. Many times they can even be folded in half. Thus again making them very versatile.
