THE NEXT STEP IN DIGITAL CONTROL electrical switching • Fast hammer blow rate for rapid pile penetration • Full energy monitoring on screen • Full history of hammer performance • Highly reliable and robust electrical switching • Intelligent stroke control • Very few serviceable parts, with on screen fault diagnostics • Easily maintained by Diesel / Mechanical tter • Cushion block irons out peak stresses • Very efcient energy transfer MAXIMUM ENERGY TRANSFERED TO PILE MINIMUM ENERGY TRANSFERED TO PILE BLOW RATE LENGTH LEAD MOUNTED MINIMUM WIDTH OF BODY WEIGHT LEAD MOUNTED WEIGHT - WITH SHEET PILE LEG GUIDES + SPREADER PLATE IMPACT VELOCITY DIGITALLY CONTROLLED DROP WEIGHT FREE HANGING WITH LEG GUIDES. THE BASIC HAMMER CAN BE FITTED WITH LEG GUIDES THAT HAVE FLEXIBLE LEG INSERTS AS SHOWN. DIFFERENT LEG INSERT CAN BE USED TO ADAPT TO DIFFERENT SHEET PILE TYPES. THE HAMMER READILY FITS PAIRS OF MOST ‘U’ OR ‘Z’ SHEET PILES WITH DIFFERENT INSERTS. INSERTS CAN ALSO BE SUPPLIED TO PERMIT THE HAMMER TO DRIVE H-PILES.

[email protected] 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 optimise hammer performance throughout varying piling conditions, such as: 1 – Hard driving with pile recoiling 2 – Soft driving with a running...
