On building sites, they use an isolating transformer to provide two 55volt lines out of phase. That means you can connect 110volt equipment across them. If someone puts a shovel through the cable, the worst shock he'll get is 55volts which is unlikely to be fatal. The physical differences are the gauge of the cable and the number of windings on the motor. 240volt equipment plugged into a 110volt supply will run off load at roughly quarter speed and is likely to stall on load. 110volt equipment plugged into a 240volt supply tends to burn out.
