Engine cranes are generally used in heavy-duty construction sites but they can actually be used for all kinds of heavy lifting jobs. Most hydraulic engine cranes contain ball bearing castors which allow them to be easily maneuvered around so the operator can efficiently and safely handle large, heavy jobs with ease.
Cranes use a variety of winches to help lift engines, machinery and other heavy items that need replaced or repaired. Cranes have been around for many years, even the ancient Greeks devised cranes for the lifting of heavy items. Today cranes are more advanced, such as the use of hydraulics which eliminates the need for human exertion even for the largest of jobs. Some cranes even contain a combustible engine for power.
Cranes generally come in two types, mobile and stationary. It is obvious that mobile means that this type of crane can be moved around easily. Some examples of this type of crane would be: truck mounted, side lift, a rough terrain crane, railroad, crawler, floating crane and more. Some examples of stationary cranes would be: a tower crane, self-correcting crane, telescopic, hammerhead, level bluffing, jib, or deck crane to name a few.
Considering they are heavy duty construction tools, hydraulic engine cranes require special knowledge to use and maintain. They should only be used by someone that has the proper understanding of how exactly all the moving parts work. In the hands of the inexperienced, a heavy piece of machinery can cause severe injuries or even death.
The general accepted definition of a crane is that of a machine that uses ropes or chains suspended from an arm with a pulley. There are other types of machines that can do lifting that do not have this specific requirement. They are not considered cranes. Some examples of such lift-like machines or tools would be a hoist or winch.
