The navvy barrow usually employed in excavating operations, and for the transference of bricks, concrete, etc., is constructed of hard wood with wrought and cast-iron fittings and steel axles. The angles are bound with iron. The bottom should have a steel plate. The wheels may be of iron, or of wood bound with iron. A strong barrow varies in weight from 60 to 75 lbs., and has a capacity of about 1/10 of a cubic yard.

A barrow of this kind can be slung by passing a hook through the wheel and rings round the handles.

Handbarrows (Fig. 204) are used for carrying light loads and materials which cannot be rolled. These may also be slung.
