THE MOVAXThe Movax vibrator unit fixes to the end of the dipper arm of a 360 excavator. It has one major advantage.The vibrator unit is able to be rotated vertically and horizontally. In normal driving mode the Movax, like conventional vibrators will clamp onto the top of a pile to drive it. However by rotating the Movax in the vertical plane it is able to grip a pile at the side and drive from this configuration. This enables a pile that is longer than the clearance under the unit to be partly driven until the pile is low enough to relocate the Movax and clamp it onto the pile top, and complete the drive.The multi-rotational ability means that the Movax can pick a pile off a stack, self pitch it, and then drive to level. With the unit fixed to the end of its arm the excavator can stand back from the pile line to drive the pile.This enables piles to be driven where access is awkward, and with less preparatory work being required.The vibrating units can in a range of sizes to suit various sizes excavators, including long reach machines.Pile accuracy is monitored via electronic instrumentation in the driver’s cab to provide true accuracy of the pile.
