A pile driving apparatus is described that is capable of simultaneously pile driving a plurality of piles. The pile driving apparatus includes a main body that travels by a traveling device, a first pile driver that is connected to the main body and performs pile driving along a vertical direction, and a second pile driver that is connected to the main body and performs pile driving along the vertical direction.

Pile driving apparatus and construction machine

A user-friendly construction machine system with shorter installation work time and wiring work time is provided. The construction machine system includes a rotary crusher unit and a feeding conveyor unit. The feeding conveyor unit is different from the rotary crusher unit. The feeding conveyor unit includes a third power reception device that receives power from the rotary crusher unit by a wireless power supply and a second motor that receives the power from the third power reception device via a wire.

Construction machine system

A scraper vehicle is described that can contribute, with a relatively simple and low-cost configuration, to shortening of a construction period, reduction of construction cost, and the like without travel being disabled easily. The scraper vehicle includes an auxiliary drive system that supplies, in excavation by the scraper, a driving force to at least part of traveling wheels of the scraper vehicle. The driving force is supplied constantly or in accordance with a travel resistance of the scraper vehicle.

A process for producing spheroidal graphite cast iron includes a spheroidization treatment, an inoculant treatment and a pouring inoculation treatment. A molten iron is subjected to the spheroidization treatment using a spheroidizing agent of an Fe&#x2014;Si&#x2014;Mg&#x2014;Ca-based alloy which contains a given amount of Ba and contains substantially no rare-earth element.
