No, crane can not lift itself (unless you mean can it pick another crane up, then answer is yes, of course: as you did not ask if the crane can pick itself up)
You can also be a 'crane'. You can pick a dog up, maybe the same weight as you!.. but you can not pick yourself up (maybe part of you, like your leg, your arm)
there are many different cranes, go to a building site and see (or see the web site I gave you below)
Whuch crane you talking about?
*Types of crane
*Ancient crane
*Medieval crane
*Railroad crane
*Mobile crane
*Telescopic crane
*Tower crane
*Truck-mounted crane
*Rough terrain crane
*Crawler crane
*Loader crane
*Gantry crane
*Overhead crane
*Stacker crane
*Floating crane
Most NB for crane is its stability (it was found them tipping over):
In order for a crane to be stable the sum of all moments about any point such as the base of the crane must equate to zero. In practise the magnitude and combination of anticipated loads is increased so that a crane should have a factor of safety against toppling of about ten times (it is based on leverage)
hope it answered you,

No a crane cannot lift its self up.A crane is used to pick heavy loads up,by using winchs or hoists.Hydraulic fluid is ran through hose that connect to the winchs.There's a lever to operate each winch,you have a main winch which is used to pick loads up over 10,000 pounds.There's an auxillary winch that picks up load under 9,000 pounds and the boom winch is used to operate the angle of the load and boom.The boom is the extension of an arm like feature.Also depending on the load capacity of the crane.A 20 ton crane and pick up 40,000 pounds and a 10 ton crane can pick up 10,000 pounds.

If you can bend over and touch your toes, bend over just a little more and grasp your toes with both hands. Next, lift your toes as hard as you can. If you now reach the ceiling (don't try this outdoors!) cranes can lift themselves as you describe. If you are still on the floor you have your answer and even know how the forces are applied (internally) to the crane. Good luck!

No.
Newton's First Law (also known as the Law of Inertia) states that an object at rest tends to stay at rest and that an object in uniform motion tends to stay in uniform motion unless acted upon by a net external force.
EXTERNAL force. Another crane could pick it up, but not itself.
The only exception occurs in cartoons.

It may do so if u urself build a crane which is capable of creating zero gravity conditions

Yeah. Try jumping off a tall building with springs on your feet to absorb the shock.

Of course it can. How do you think they move those things around? They're MAD heavy!
