Dawson Construction Plant has developed an industry leading, robust and simple, electronic control system that constantly monitors the drop weight position. This constant monitoring allows the switching timing on the main hydraulic spool to be trended to continually optimize hammer performance throughout varying piling conditions, such as:
1 – Hard driving with pile recoiling.
2 – Soft driving with a running pile.
3 – Cold hydraulic oil on start up.
4 – Raking piles.
