Maybe you could evaluate if you actually require permanent access / platforms etc.

Not my first choice, though if CAPEX is of a premium, maybe maintenance could be completed from EWPs in lieu of permanent infrastructure etc.

Could you name a few rules to help me in this reduction?

The products to be used are soybeans and sugar.

Below are some loads that I'm using, you use less?

Regards

Walkways along Belt Conveyors 3 KN/m

Maintenance platforms for Belt Conveyors 10KN/m

Access platform, walkways and others (auxiliary areas) 3 KN/m

The weights are there for a reason as you will be moving tool boxes,

small parts, pulleys, welders, lights, bearings, gears, roller chain

plus multiple personnel working in a confined environement that

is very very small in square area.

SO what your saying is you want to compromise the safety of multiple employees

inspecting and or working on your conveyors that are or may be tower mounted

by installing material that does not have the structural strength to the standards

you have decided to compromise?????????????????????????????????????????????????

It is an extremely foolish endeavor that will invite injuries and or fatalities.

You need to spend some time looking for high strength stair treads and decking made

from extruded fibreglass before you make any more mistakes that will be extremely deadly.

ANY area which surrounds a drive unit should have solid metal decking for the reasons mentioned above. ■

Leon's warning should be taken to heart.

Spillage depth has been ignored throughout your proposed loadings. Consult Foundations, a Martin Engineering download, which will explain the situation. Have you considered blocked chutes?

Legal standards do not exist regarding loads imposed along gantries. Therefore you have to apply the local structural standards using loads which are adequate for the purpose. I have had Contractors contradict me on depth of spillage, chute blocking etc in their alleged self interest. Professional Engineers are obliged to advise the Client of their concerns one time only. I've always found that a Client has already made up his mind to cut corners so once is always enough for me. Due diligence fulfilled!

If you have an incident during construction or operation you will be accountable according to the advices in this published thread.

Suppose the belt gets caught and the motor runs up to stall torque: with a concave vertical curve you have to prevent the belt's built in safety level from pulling the tail end out of the mountings.

Placating a miserly customer is never wise. Investigate what corners are being cut elsewhere on that plant and then investigate your payment situation. Your situation was well known to very early mariners as the title of the reply suggests. Ha'p'orth =Halfpence worth. I apologise for the imperialist undertones....like 'The hell I do.' ■
