The anchorage requirements for the excavator assembly to the shaft
bottom, which not only support the excavator mounting ring but resist the high
bucket break-out forces required for adequate excavation of the clays, are
catered for by a custom designed combined steel and concrete cutting edge
designed by AMEC.
In order to minimise inaccessible hydraulic valve work at the
excavator, the system incorporates individual feeds of each function direct from
the power pack via a hose management system. is is designed around the existing
shaft top set up.
A stand-alone containerised diesel powered hydraulic power pack
provides the motive power with an operator's control cab incorporating all
controls including a positional feedback monitor display of the excavator arm.
The power pack also incorporates hydraulic feeds for operation of the shaft
jacking system.
Currently the excavator has completed two shafts operating
submerged at depths as low as 20m below water level. It is shortly commence on a
third shaft.
Close collaboration with AMEC allows ongoing development of the
prototype machine and patent rights are being pursued.
