Overhead Coring for Wall Plug Installation

on April 20th 2009, i went to Bintulu to train a customer who bought Hilti DDEC1 complete with DDREC water recycling unit for an overhead coring job.
they want to install a pipe support using Hilti HVU system but the column are rebar infested so drilling with drill machine has no use.
complete set up to do coring overhead. no wall plug needed.

easy to do coring overhead and very easy to move to next coring point.

easy to operate.

but the customer are using it in MLNG2 plant which prohibit me from taking actual application photo.

Suria Sabah Cutting Job

early April i went to Kota Kinabalu to conduct a site training for our new Diamond Service Contractor, Redback Construction Sdn Bhd.
Suria Sabah is a development on a reclaim land at Kota kinabalu, boasting a shopping mall combined with 4 or 5 star hotel.
Currenty there are demand to change the location of teh escalator as shop owner complain that a few escalator are not in their favor as the location of the escalator will tend to make shopper not notice their shop.
big beams with no time to waste makes it a no choice for hacking. so Redback step in to do the cutting thus eliminating touch up needed after the job finish as with diamond cutting you don't need to touch up later.
cut the tile mortar with DCH300 electric cutter and PMC 36 line laser so we can plant drop in anchor inside the concrete, not inside the mortar.


After separating the slab, we cut the beam using the 1200mm saw blade. LP32 proved to be reliable to cut even beams full with rebar.

As you can see, 44 number of rebar with steel link cut through as well. no problem with Hilti DLP32 wall saw system.

All girls cutting team posed with Hilti TS5SE electric wall saw.

Overhead cutting with DLp32 wall saw system. the machine is hanged upside down by Hilti HSA anchor. cutting 500mm thick excess slab.

DSTS5SE cutting rebar. the electric wall saw are very silent when not cutting. also comes with silent blade if the jobsite cannot endure excess noise level.

After cut, remove the beam with forklift. the supervisor smiled happily as one problem goes away already.

KL Pavilion Tower crane Base Demolition

KL Pavilion is an upmarket shopping center located in the heart of Sungai Wang, boasting a very refresh experience for shopper (with loads of money of course) and a very classy shop lots.
Last February our customer, CASES sent in their LP32 wall saw unit for service. while we service their unit, we lend them our loaner unit as they cannot stop the job.
as the construction finish, they need to remove the tower crane base so they can utilize the space for other usage. CASES got the job and use their LP32 to cut as the beams are very big and thick.


Hacking are very slow and as you can see, you need to cut the rebar later.


sent the repaired unit back to them. in front is our loaner unit.

the boss using the wall saw system. very easy eh boss?

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.

Alpine Pipe Diamond Coring

Last January there's a demand for coring from Alpine Pipe manufacturing factory. They need to core a lot of holes to accomodate new machines. Hilti TSR, Yvonne Chean already closed the sale of 1 unit DD200 with 23 units of DD-B 202 U4 core bit. so with the big number they buy, i'm showing myself to see everything is in order.

coring on floor slab 8"

stitch coring.
each point takes around 20 minutes as there was T25 rebar 2 layer. combination of consumables and great machine proves the best solution.

Jedok Granite Quarry Wire Sawing

At 0400 hour, i started the long journey to Kelantan to fulfil a job task: testing Hilti CH Wire at a granite quarry. the task is set up by Darryl Fong, Key Account Manager for Hilti Malaysia, you're the man, bro. if we succeed this task, we are blessed with infinite sales of diamond wire for the next 47 years. My task is solely to see if the wire are up to the quary standard. this is a new experience to me and to Hilti Malaysia generally as we never have experience on granite 100%. all we encounter all these time is concrete and this CH wire are the best for this application. now, its show time.
A windy and breezy morning greets me as i exit Kuala Kangsar PLUS exit and enter Jalan Grik - Pasir Puteh. I open the window and enjoy the breeze. You'll never get this at KL.

I stopped at one of the peak of the mountain road. Later i discover there are a better stop with better view but i'm driving too fast that time to stop.

Getting into the quarry, at last. After 8 hours driving, i still need to do some work before i can rest. Delivering the CH wire to the Site Manager. The granite hill greets me gracely.

Breakfast next morning. Ayam Bakar and Nasik Lemak. Really nice food. Kelantan is well known for their exotic food and i agree with the statement. You'll never get hungry here.


A granite block after finish cutting will be broken into smaller pieces. Seen here the worker are already drilled holes before they pouring the expansion mortar so the block will crack itself.

Some view. you can see also the smaller pieces ready for shipment.

Myself with Marini Quarry Sawing Machine. MAde In Italy. Price? Merc E200 Kompressor.

The granite that already sawed off. nice cut eh?

Overall picture of the setup. Be a distance away when the wire start cutting. safety precaution. Why? Leave Comment to ask, TQ.

Myself with smaller granite pieces. Even this small, it is 6-7 ton heavy.

About the performance, i need to wait until this friday before i get my answer. One cut used up 3 - 5 days. Damn, i never expect it will be this long. Roger and Out, i'm coming back at Wednesday, Dec 17 at 0200 hours.
