Abstract
A tracked crane for hoisting and moving large objects in which the tracks are preferably pivotally mounted so that they may be elevated by jacks and horizontally pivoted into another direction. Following this, the crane can be driven in the other direction without turning. The crane may also have pivotally mounted pressure cylinder lifting means, and apparatus for pressing the top of the load carried by the crane to prevent bouncing of the load as the crane travels, and to hold it down during its installation as necessary.
