MTBF Of Electric Forklift Trucks And Over-Head Cranes

US Mil standard cover this issue in details but I forget the number,Also there is a "Juran's handbook of quality control" its expensive but worth.

7 Clark12 - Clark Forklift Type 1 hours=395:49 tfailure class=3 Type=Forklift From Google 37.400 answers. It is once more demonstrated that before asking here a research with an engine gives at least an indication.

Thanks for your help anyway. Now I am not familiar with the reliability field. Could you explain the meaning of "395:49"?

MTBF

hh:mm d:hh:mm

395:49 16:11:49

values of MTBF in different time units.

I have understand the meaning. 16X24+11=395 hours.

Contact the various manufacturers of the equipment and ask them.

You want this forum collect the information for you?

if one has no desire to help, it is better to ignore the thread and leave, rather than post something that is unhelpful. just my 2 cents, and no offense intended.

Coooool. sorry if my comment hurt you. This Forum encourages funny answers.

I didn't know that was funny.

OP is a newbie. be considerate. older members will tolerate you. newer ones will shy away and think this forum is full of rats.

if your first post was met with such a reply, how'd YOU feel? stay cool, kid.

Yes, I just did not realised that this is his first post. Thanks for correcting me.

welcome.

hi shemeshi,

lynchlynch's answer is good.

another or an additional approach works on the assumption that your company has been in existence for years, and that the maintenance department has kept good records of their activities for each machine / equipment. if this is the case, you can review these, and find out the actual MTBF and MTTR of these equipment.

it's a longer and tedious approach, I know, but it gives you a more realistic figure, and something the manufacturers themselves would be interested to know.

HTH!

Impression that I got from OP is that He/She belongs to a Electric Forklift Trucks And Over-Head Cranes manufacturing company and is appointed as a reliability engineer there, And He/She is looking for help in regards of MTBF and MTTR, AtLeast thats what I was assuming.

From the start I thought he is in a company which has a park of fork lifts and cranes and wants to know if their results in exploitation are or nor according to the average values i.e. if teir maintenance ahs or not the right level.

Having worked in the trade for a few years i would take any information coming back from the engineers with a pich of salt

WHY ? i hear you ask.

well one of the problems with the reports, is the reason for writing them, when i Atlet uk, was the insistence of the company asking for each and every hour of each day to be accounted for, well on days where the trucks didnt break down in order to get the day in (time wise) we had to result in making up faults to fill the day.

I questioned the management approach to insisting the day be accounted for, and management said it had always done this. ( doesnt mean its ok though)

as a result of this culture, 90% of the faults highlighted on our feedback reports from management were misleading as the faults were made up.

if i can help more please e-mail me,

such false reporting would be easily discovered since the usage of the equipment will also show up at the equipment users' records.

if anyone from the top of the company was looking at these 2 conflicting reports, someone was surely telling a lie. and if production was not hampered because the mobile equipment were available, it will become readily apparent who was lying.

IMHO, for a good maintenance / repair manager, there will always be something useful to do when all equipment are in good working order, other than making up false activities / work.

The establishment of <...MTBF and MTTR of electric forklift trucks and over-head cranes...> is the basis of the work of the <...reliability engineer...> . That role involves collection and analysis of information at the facility in question over a period of time.

Therefore maintenance records are the first stop. Start with the head Maintenance Engineer, and be redirected from there.
