enk van Kuijk, director of Dutch industrial company Vanku, decided that squatting/kneeling and shoving the bricks into place on the ground was just too hard and slow, so he invented Tiger Stone, a paving machine that is capable of laying 300 square meters (3,229 sq.ft.) of road a day, whereas a single conventional paver on their hands and knees manages between 75 and 100. The Tiger Stone is available in four, five and six-meter (13, 16 and 20-foot) widths and the paving width is adjustable from the width of a road to as narrow as a bike lane or walkway; the device is fed with loose bricks, and lays them out onto the road as it slowly moves along. One to three human operators stand on the platform of the Tiger Stone, and move loose bricks by hand from its hopper to its sloping “pusher” slot – the bricks do have to be fed into the pusher in the desired finished pattern and you can draw zebra crossings, bikeways, ecc. There are no moving parts within the machine: bricks are automatically sorted and packed together by gravity, each stone will associate with the link previously made. There is a quiet electric motor that moves the machine along a bed of sand, so noise and maintenance are kept to a minimum. It stays on course thanks to built-in sensors, which follow the curbs .
