Estimating the term…
A hydrophilic film coating (11) is formed on outer surfaces of cab (5), equipment housing cover (6) and counterweight (7) of an upper rotary body (2), so that a water film (18) is formed on the surface of the hydrophilic film coating by raindrops or at the time of rainfall. By formation of the water film (18), contaminant substances (13) which have deposited on the outer surfaces of the upper rotary body (2) are urged to float up and carried away with dripping water of the water film (18). As a consequence, it becomes possible to prevent development of raindrop stains on the outer surfaces of the upper rotary body (2) and, even if spattered particles of grease have deposited on the outer surfaces of the upper rotary body (2), such contaminants can be easily washed off, thereby permitting to maintain the quality in outer appearance of the upper rotary body (2).
A rotary type construction machine having a self-propelled base carrier and a rotary body rotatably mounted on said base carrier, characterized in that a hydrophilic film coating is provided on outer surfaces of said rotary body.
A rotary type construction machine having a self-propelled base carrier, and a rotary body rotatably mounted on said base carrier and having a cab mounted thereon to serve as an operator's room, characterized in that a hydrophilic film coating is provided on outer surfaces of said cab.
A rotary type construction machine having a self-propelled base carrier, and a rotary body rotatably mounted on said base carrier and provided with an equipment housing cover to house therein an internal combustion engine along with other equipments of said machine, characterized in that a hydrophilic film coating is provided on outer surfaces of said equipment housing cover.
A rotary type construction machine having a self-propelled base carrier, and a rotary body rotatably mounted on said base carrier and provided with a counterweight thereon, characterized in that a hydrophilic film coating is provided on outer surfaces of said counterweight.
A cab mounted on a rotary frame of a rotary type construction machine and formed in a cab cover structure having front and rear plates, right and left side plates and a top plate, characterized in that a hydrophilic film coating is provided at least on outer surfaces of said front and rear plates and said right and left side plates of said cab cover structure.
An equipment housing cover for use on a rotary type construction machine, said equipment housing cover being mounted on a rotary frame and formed in a housing structure including at least right and left side plates and a top plate provided between upper ends of said side plates, characterized in that a hydrophilic film coating is provided at least on outer surfaces of said right and left side plates.
A counterweight for use on a rotary type construction machine, said counterweight being provided on a rotary frame and in the form of a mass of a shape having at least front, rear, top and bottom sides, characterized in that a hydrophilic film coating is provided on outer surfaces of said counterweight at least on the rear side thereof.
