Diamond contractors?

[Sparffo]

Hi!

as a Diamond cutting and drilling contractor, i would think it could be great to have a topic for us also ;)
It could be under the Demolition main topic!
what do you guys think? cutting concrete is a quite big industry today!:drinkup
the name for the topic could be: Diamond tools.

i can start the first thread on that :cool:

people could ask questions and share information about the stuff involved.

also asbestos works could be a interesting topic?

Dam, read the title and got all excited, thought you was in the mining side and had some samples at the right price :D

Sounds like a good idea to me Sparrfo, there is some amazing gear you boys use, was watching a chain saw cutting concrete last night. :eek:

this is a good way to get girls "I have a diamond drilling company" :D
you don't have to tell them that you are messing around with industrial diamonds completly covered in dirt ;):D:D

the saw you watched was probbably something like this?

^^ thats me cutting with it :) the blade "a little bit longer" than on normal chain saws :cool:
and it has 7,5 KW turning the chain ;)

The diamond wire saw is also quite cool!

hard to get a good picture of it...

Ye that looks exactly like it, only the blade looked a bit shorter.
They were using it to cut straight ends on the concrete channel that had been slipformed a couple of nights before so thay could fit the manhole adapter. ( see "other paving equip"thread)
I have seen one demo'd at a show a few years back, it was cutting holes in concrete manhole rings, very impressive.

they usually have them at demo shows ;) it looks so easy there...
but in reallity it's a very expensive and hard tool to operate:Banghead
we use it only when there is no other choise! the chain cost here in Finland around 1000€+-500€ depending on lenght... in $ it's 1.5 times that price :eek:
but customers like the machine when we don't have to make any "over cut's" like with the normal round disk cutters!

Are you saying the saw is electric? I see it has 3 connections onto it. I figured one was water for cooling, but I didn't know if the others were hydraulic or electric lines.


I like the wire saw. How close to the rest of the floor can you really get?

The chain saw is hydraulic, the 7,5kw power pack we use is then again electric ;)
Dr.bender (gölz) make a high frequenzy chain saw, but i haven't had any need of the problematic HF chain saw, we already have a HF hand saw, and it's a pain in the ...

you are right on that one connection is for water, the chain saw needs A LOT of water, othewise the blade turns blue and is scrap metal after that. the other two lines are pressure and return oil lines.

I added some more wire sawing videos now! at the moment we have a dam project going on, lot's of diamond wire sawing and demolition robot work, I will add more movies later!
"How close to the rest of the floor can you really get?" this i didn't understand? with the wire saw it's possible to do almost anything!
if we can't get close enough the floor, then we usually sink the support wheels in the floor. like we did in this video:

here we are cutting about 1-2" under the floor, to cut loose a thick metall plate.

Is that yours? Details on how it works. I have wondered about RCX.

you are funny as heck. looks like you've had some success with the women, though, judging from the pictures you have posted . . .

"BROKK 40 loading conveyor belts"
http://www.youtube.com/watch?v=Ji46j4Znv0A&feature=user

yes the Brokk 40 and the minivoyer belts are ours :)

what exactly would you like to know?

the conveyor belts are driven by 220v electric, all by one suply. they can carry up to 35¤ angle.

the robot again is running on 380v 3 phase electric, a 4,5kw electric motor drives the hydraulic pump. the robot can be radio or cable controlled, so the operator can be on safe distance (can even be operated trouh the internet :eek:).
Our robot is equipped with buckets, atlas copco sbc60 demolition hammer, darda cc260 concrete cutters, also other attachments can be fitted.
the controls are almost the same as on a excavator, it only has a little bit more functions because of the different boom model.
The boom is made for demolition, so its not the optimal digging configuration, but great for hammering.
I have been thinking about making a excavation boom for it, we use it quite much inside buildings when digging trenches for new pipes.
the machine weights only 380kg (750 pounds) and is 60cm wide (24")), so it fits almost anywhere.
need to know more? i'll be glad to answer your questions :)

what is it like working with a demolition robot versus running the hammer on a hoe or using a good old fashioned jack hammer for demo?

the robot is made for demolition pourpouses, when the excavator is made for digging= the robot is sooooo much better to do demo with!
some differences:
1. exhaust fumes, the robot is electric driven (the brokk 330can be fitted with a diesel)
2. remote control, you can stand anywhere to get an optimal view of what you are doing. with excavator you don't see the hammer tool.
3. safety, with remote controll you can work at safe distance.
4. the boom, it's designed for hammer use and it's a lot more compact and easy to use on walls than on the ex.
5. support legs, most of the new robots are standing on 4 legs, instead of dozer blade= it's a lot more stable.
6. surface pressure, it's lower because of the wide spreading legs. (how about chicks? :D)
7. tool carrying capacity, it can handle a heavyer tools than a excavator in the same weight class.
8. reliabyility, ok this is a little bit double sided... the electrics usually break on these robots, but the frame and hydraulics are a lot better.

thats some points in short ;)

when hammering floor the excavator is quite effective, on thin surfaces it can even be faster, mostly because of the faster moving of the equipment. and on floors you see the tool point, therefore it's also easy to use. the robot again don't deserve as much height as the excavator, so it's often better on inside jobs.

when hammering walls the robot beats the excavator 10-0, you don't stand a chance with the excavator in breakin performance.
measured from the wall to the back of the machine the excavator can need up to 5 metres of space to be able to hammer the wall, it's usually very unstable then also, and you can't se the tool point...
the same job with the robot can be done with 1-2,5meters of space, and you can stand besides the tool (with safety gogles on).

I couldn't even imagine hammering upwards with a excavator, with the robot it's not a problem at all, even at maximum reach.

but i really hate to look after the cable when working...
and the strange electrical problems can really beat you up:Banghead
