Twenty-four Tons at a Bite

An electric power-shovel with a dipper that will gouge out nearly twenty four tons of earth at one bite is to be used in the open pit mining of coal in Illinois, United Ctates.

The shovel boom is 120 ft. long and the dipper stick 82ft. long. Material can be lifted to a height of from 90ft. to 100 ft. and deposited over a radio of 150 ft. from the centre of operation. Only one man is needed to control the shovel, which is worked by three hand levers and one foot pedal.
