Crane is a tower or derrick equipped with cables and pulleys that can be used both to lift and lower materials and to shift them horizontally. Cranes are commonly employed in the construction industry and in manufacturing heavy equipment. Construction cranes are usually temporary structures, either fixed to the ground or mounted on a purpose-built vehicle. Cranes may either be controlled from an operator in a cab that travels with the crane, by a pushbutton pendant control station, or by infrared or radio control. Where a cab operator is employed, workers on the ground will communicate with the operator through a system of standardized hand-signals or, in larger installations, radio systems; an experienced crew can position loads with great precision using only these signals.

Crawler tractor is a vehicle with tracks instead of wheels. The tracks spreads the weight of the vehicle across a larger area, resulting in a lower ground pressure compared to wheels. This makes them very well suited for use on soft ground, mud and snow. Crawler tractors are well suited for many revegetation and reclamation projects because they are rugged and versatile machines. The features include electrical drive with two motors for all functions, two independently driven and suspended crawlers, lift arm for agricultural tools, delivery axle to drive additional tools, trailer coupling, two speed gear box, openable hood and door & fully detailed operators cabin.
