What Doesn't work? Does the "pull" in the chain over-ride the take-up spring tension and then the chain jumps around the sprocket at "B". Answer: Remove the Spring and have a simple screw type chain tension device at "B" What is the total weight of carts, including load being carried, what...

Ambaflex, Denipro are suppliers of complete spirals. They have already done the hard work! Use their experience. Ross

Paddy Sorry for just seeing your post. Is the roller brush driven independent of the conveyor belt or are you relying on the belt to rotate the brush? If not, ensure that the brush runs faster then the belt surface speed Is the brush contra rotating to the belt travel? Has the brush got a spiral...

Hi Scoutb59, I have seen these type of rollers used in plants manufacturing wire rope and electrical cabling, but cannot offer details on a supplier for the complete roller. If it is any help, Wellington Bearings in Melbourne Australia manufacture bearings (of various configurations) and do...

The "Theory" of handling product on a roller conveyor is to have the roller pitch so that the centres of three consecutive rollers is equal to the product length, in your case with the 4" dia product, the centres between each adjacent roller needs to be 2", so that the distance from roller (1)...

Jpn5 For your information, this "brand" of motorised gearbox (Bonfiglioli, STI,etc) are made in Italy, and have a hollow output arrangement. If you remove the bolt on the opposite side to the bush, you should be able to remove the whole shaft from the output, which make it free for you to do...

Metman what are the approx physical dimensions of the vessels you require-you may get a better price out of Sydney (business is pretty slow here in Sydney at present), freight may be the killer though. I could get some freight estimates if you want. Ross

Metman I am Sydney, 1000 k's south of Brisbane. All three are suburbs of Brisbane. (Use Google maps to locate) Ross

chumet Many factors come into play, bag material, speed, conveyor design etc My Gut feel is that "old" coal plant belts will not work. A static test will not prove anything, as you require the dynamics of movement to get a true result. There are speciality belts available that will succeed at...

Hi Mr Ridley Firstly, you need to advise the means of driving this conveyor. I assume from your notes that the existing rollers are 2.75", but how do you intend to impose drive to these rollers(Chain, vee belt, timing belt, flat belt etc) as this will then determine the best means. So far your...

Have a look at "sail" track-used on sailing boats Would come in 316 s/steel. Check out Sail boat Hardware perhaps

Try Martins trailers in Perth WA. No connection with such, but have used as a supplier on lighter equipment. ross

Dumb question-what oil pressure is he getting? I am happy to defer to the experts above, but "normal" oil pressure for the standard Kent engine is 40 psi. My twin cam runs 35/45 psi and talking to more knowledgable persons than I, the consensus is volume is more important than pressure. Chasing...

A good estimation is: Total load on belt(pounds) x friction factor x belt speed (in feet per minute)/33000 = HP Ross

Hi Caveman Jones Below is the details of what I was trying to say "The torque arm concept is the most preferred, since it enables a hollow shaft reducer to hang from a solid shaft and to be totally supported by that shaft. A torque arm is simple to install and guards against potential...

Hi Caveman I think your SEW rep should have another think about what he said: ""dont recommend putting reducers between bearings because of the shafts not being perfectly straight."" If it sitting on the shaft it must be straight-the flexible mount within the torque arm will take up any...

Hi Caveman I have come into this discussion a bit late. However, we build many conveyors in a given year using SEW and other brand hollow shaft gearmotors with torque arm mounting. I surmise that this application is for a lift up transfer in a pallet handling system and would guess that the...
