Heavy Metal Task Force

The longest road-going vehicle brings electricity to an isolated region; tunneling behemoth digs a new subway system; sleek vessel fights the war on narcotics.

The world's largest wheel loader digs a copper mine; an assault transport that goes across land and into water.

A massive dredger gets the Big Apple ready for the world's largest ships.

Dredger must cut through volcanic rock in just four hours; a rig wreaks havoc until threatened by a force stronger than itself; a chopper faces a test.

The heavy-lift ship transports one of the largest cargoes in one piece; transporter tries to deliver a 100-ton telescope.

A crane vessel pieces together an oil rig; digging a tunnel beneath a peaceful seaside village; armored haulers remove lethal slag from a smelting plant.
