DD EC 1 Overhead Coring

at 20th April 2009 i went to Bintulu to conduct a site training for Amalgamated Steel Sdn Bhd, a contractor installing downstream pipe at MNLG Bintulu. as a fact, it is impossible to do overhead coring as the water will flow down and going into the coring machine and electric shock can injure the operator, not to mention saying bye bye to the coring machine.
anyway, Hilti already develop a way to do overhead coring and for this case, for anchor holes, DDEC1 diamond coring machine is the best. featuring Top Spin technology, the coring is up to 50% faster than normal coring machine.
Hilti develop a system for the user to do overhead coring in such a way the user don't need to install drop in anchor or to use vacuum base fastening.
An extractable stand come with DDEC1 baseplate is used to fasten from bottom floor up to the upper floor where the user want to core. very fast adjustment and very less hassle to the user.
This is how the set up look like.

used with the DD REC1 water recycling unit that will supply, take the contaminated slurry, filter it and re use the water up to 50 holes.

use a ladder for easier access.

the job in MNLG Bintulu i cannot take picture as Oil & Gas facility is very strict on safety. you cannot bring in any spark inducing devices such as camera, mobile phone and such.

anyway the customer happy as this set up makes them work faster.
