Comments - Tom March (Site Foreman)
"Could not make any headway with hydraulic hammer as the depth of the trench increased, actually getting somewhere with the Rockwheel. Two hydraulic hammers broke within a month and the tool was only lasting two hours."
This project was an example of the flexibility a contractor gains with the inclusion of a ROCKWHEEL into his fleet of equipment. The ability to be able to swap between a bucket, hydraulic hammer and ROCKWHEEL ensures most tasks can be performed without the need for specialist equipment.
