Groundwork has combined efficient operation and accuracy into compact machines. These new models are well suited for working on solar installation projects, congested job sites, and civil fencing and guardrail installation applications.
With mast arranging from 2.9m to 6m, the rigs allow the operator to drive pile up to 6m (20ft) and yet can remain fully assembled when transporting, aided by the two- to three-stage mast. In addition, with transportation weights up to 5,686kg for the Challenger 1200, multiple units can be transported on a single trailer.
The Challenger range has machine-integrated controls located on the side of the machine. The rig features a fully-functioning wireless remote control that can engage the hammer, accurately align the pile to complete verticality using the auto plumb feature and position the machine.
Both new machines can utilise an optional laser receiver or a compatible GPS system to help improve productivity by better aligning the machine to the specified pile install location. GPS can be either manual, semi-automatic and fully autonomous solutions.
When the operator hits rock or ground that is too hard to drive through, they can fit a rock drilling attachment to the machine. Drill sizes start at 68mm and go up to 350mm.
Both pile drivers are powered by a Yanmar 48hp (36.5kW) Tier 4 or 5 diesel engine. With a two-speed travel motor, the operator can quickly travel speed of 4km/h.
With the hydraulic hammer pull-down, the operator can install pile or screws quickly.
