Cableway, aerial - Conveying machine for transporting unmarried loads along a suspended track cable.

Cab-operated crane - See cranes, sorts of.

Camber - The mild curvature given to beams and girders to atone for deflections as a result of loading.

Cheek plate(s) - The desk bound plate that aid(s) the pin (axle) of a sheave or load.

Cheek weights - Overhauling weights connected to the aspect plates of a decrease load block.

Chinese finger - A wire mesh pulling grip, usually used with twine rope, into which a line is inserted and that tightens round the road when pulling pressure is applied.
