Is really necessary to shiploader be prepared to hoist the bulldozer and wheel loader?

Buenos noches Paulo,

A shiploader is designed to carry the conveyor and the product to be

conveyed plus an operators cabin if so equiped and be stucturally sound

to resist wind loads to a certain extent.

It taks a very large amount of structural steel to increas a ship

loaders ability to hoist a bull dozer off a dock and then swing

it over to a ships hold and then lower it into the hold and then

remove it as you need a crane that would carry 3-5 times the

weight of the bull dozer for the safety factor.

For the work involved you will be much better off purchasing

a high speed material thrower to use off the retractable

spout and operate the high speed thrower with a

radio control unit which will do two things for you:

1. The right high speed thrower will allow you to operate it with

radio control out of the ships hold.

2. rotate the ship trimmer/high speed thrower under the

loading spout as you load the ships hold

3. eliminate any need to enter the hold

If you type the words "ship trimmer" in the search box

you will see a very nice photo from Gary Blenkhorn of the

type of trimmer I have been telling youy about loading Halite

into a lake boat on Lake Huron at Goderich, Ontario, Canada

You need small bull dozer with SWAMP tracks for floation and if you expect

to sell these beans for human consumption you need to use a food grade grease

if the idlers are not sealed.

If you have a ship trimmer installed there is no need at all for a bull dozer with swamp tracks.

Please contact Lyn Bates by PM here on the forum and he can help you quickly with this. ■

Ignore the so called 'additional' structural mass. You won't get a slinger for no weight. Slinger belts are often a 1 piece autoclaved affair for balance and safety. Do you have an autoclave handy?

What you need to consider is soy bean degradation; the attitude of the Deck Officer and the local environmental regulations.

Loading is performed according to the manual kept by the Master and the Deck Officer complies. Apart from the possible degradation of the cargo there is also an explosive element when sugar dust gets thrown about willy nilly. Suppose your belt snaps halfway through loading. You'll wish you had a Bobcat then.

If you have to control dust, like they do in most of the developed world, you cannot reasonably water spray sugar.

What size ship are you talking about? Why can't you plonk the loader over the hold using a mobile crane. You should have a mobile unit somewhere around the port.

Who quoted you a bulldozer in the first place: and did they guarantee that the dozer would pass under the coaming? ■

Good evening John,

I cannot immediately find the photo of the ship trimmer that

Gary used at Goderich but I have uploaded a photo of a Metso

unit for the example. The unit that they use at the

Coastal minerals Halite Mine at Goderich is about half that size and

I am unsure if it was destroyed when the Tornado hit the

City of Goderich Ontario Canada and then the

Coastal Minerals evaporated salt plant on the shoreline next to the

Halite Mine

Greetings forum friends

Interesting application...my thoughts are who is going to draw the short straw and ride the bulldozer?? The power flinger should work fine for both products...it will be remote controlled and allows for product placement.

When you start to zero in on Shiploader designes and suppliers we would ask that you consider our Twin Orbiting Shiploader. Uniquie design reduces your civil construction costs..AND elimates the ordinarily necessary surge bins.

Modern, efficient, and cost effective.

Hope to hear from you.

Best Regards,

What size ship are you talking about?

Answer : minimum :Handsize 20.000 dwt; maximum : Capesize 120.000 dwt.

General comments : The buldozer pass under the coaming. About mobile unit, I can't use it, my loading rate is 3.000 ton/h.

Best Regards.

An autoclave is a pressure vessel which is often/usually closed by a dished end secured by swing bolts for fast opening and closing. Sucvessels are steam heated and in this instance they are used to cure the splice of slinger belts. This is the correct technique because these belts are subject to horrendous wear rates and balance is critical. (Using remote control is entirely at the discretion of the Deck Officer. Stevedores are allowed on the ship by invitation only and their presence has important legal and security obligations for the Officers, especially if the cargo is for foreign parts.)

Another shot in the foot is the revelation that Capesize ships will be loaded. A boom that can span Capesize holds is definitely not going to feel the

weight of a small dozer to any extent.

A mobile unit was suggested to lift the bulldozer over ships rail. If you consider a slinger for 3000t^-1 you might certainly need an autoclave and it is a 'handy' worthwhile investment.

Depending on the trim regime for a Capesize it might be necessary to distribute cargo over distant holds and you will probably need more than one Bobcat to meet the demurrage conditions, even with or without computerised draught surveying. ■
