Over the years, the family business has grown into a group of varied companies and has locations in many countries, including Germany, Australia, Britain, Ireland, and the United States . Since 1958, its Irish factory in Killarney , Co. Kerry has built container cranes, exporting them worldwide through the port of Fenit . In Australia, the group in 2013 commenced an AU$65 million expansion of their local headquarters in Adelaide . The development includes adding a new three-storey office, workshops, warehouse, component plant, and distribution centre to the Para Hills facility.  In the ., the group in 2012 started spending US$ million (about € million) on a three-year renovation and expansion of its Newport News, Virginia factory, offices and warehouse.

On 19 February 2013, representatives from the Commonwealth of Virginia and the cities of Newport News and Hampton announced that they would make grants and incentives available for transport improvement, training, and property investment. 
Thus far, we have described the main characteristics of neurons, including how their processes come in close contact with one another to form synapses . In this section, we consider the conduction of communication within a neuron and how this signal is transmitted to the next neuron. There are two stages of this electrochemical action in neurons. The first stage is the electrical conduction of dendritic input to the initiation of an action potential within a neuron. The second stage is a chemical transmission across the synaptic gap between the presynaptic neuron and the postsynaptic neuron of the synapse. To understand these processes, we first need to consider what occurs within a neuron when it is at a steady state, called resting membrane potential.
