Crane rocking clearance refers to how much space is available for a crane to move. A specific amount of space is needed to use a crane safely.
A school bus typically requires a minimum of 14 feet of overhead clearance to safely navigate under bridges, power lines, and other structures. This clearance ensures that there is enough space for the bus, which is about 10 to 12 feet tall, while allowing for any additional obstructions such as cargo or snow on the roof. Proper clearance is crucial for safety and to prevent accidents.

Bearing clearance is the distance between the crankshaft journal and the bearing surface. It is usually referred to as oil clearance, as that's what is occupying the space.
ground clearance?
No, only specially designed rockets can go up into space. As soon as a helicopter reaches our atmosphere boundaries, it would burn up. Rockets on the other hand, have been specially made to hold such extreme temperatures. :)
