    Abstract

    The laser theodolite is known for its wide-range application, easy operation and high precision. In the installation and repair of heavy duty cranes, laser theodolite is superior, so far as efficiency and geometric accuracy are concerned, to the conventional instruments for measuring horizontal and centre line of the machine parts.
