To remove a concrete ramp previously used for unloading trucks located at an automobile repair center.
The Ramp was 1.5 m high, 6 m long and 1 m wide.
A single worker drilled holes in the sides and top of the ramp at intervals of about 1 m, with a hand-held pneumatic hammer drill.
Then horizontal cracks were produced with a C 9 N splitting cylinder and portable Elecric power unit(type EP).
The ramp walls were dislodged from the substrate. They were then split into pieces vertically by means of the splitting cylinder.
An excavator then piled up and removed the rubble.
