Hi all

Sanity check required , thanks in advance.

OK large main crane in use develops a fairly large spill beneath the undercarriage 5x5 meter surface area on ground. As a guide I would say possibly 20 + litres of fluid what looked fairly black in appearance which I see as the very least aged fuel maybe hydraulic oil ? (this is fairly new piece of crane 1120)however.

Immediately instruct a report to give assurance to PC that the capacity of the crane has under circumstances been compromised before even thinking about carrying out the next critical lift.But they carry on regardless.

Regulation 10,3 para 360 L113 clearly states defects which are commonly noted such as : cracks - permanent deformation -corrosion of vital parts-excessive wear - failure of moving parts.

Question: Surely a spill of this proportion must be investigated by a competent person and no just explained off as captured fuel releasing during de rigging operations. ie this is defect which could cause a hazardous state to the same effect as above?

FYI I am pushing extremely hard with this issue to the point,, well the usual point we all do on regular basis and I am not backing down. Until of course LOLOR inspector on here maybe tells me let go ?

Thanks all

OK, it's not aged fuel, how could it be, fuel is used as the crane operates, so it can't age.
It could be due to an overfill of the hydraulic tank by an inexperienced operator, which would have no effect on the operation of the crane.
How does a spill of oil relate to your quote from LOLER?
IF the defect was permanent then the leak would continue, e.g. a crack.
So.
More detailed & accurate info required.

Black Hydraulic Oil??

More likely lub oil or perhaps fuel oil (diesel) if it has spilled on tarmac.

Have it analysed.

As others have said there are various fluids that could leak

Diesel fuel - the liquid sounds unlikely to be diesel, as diesel wouldn't be black in colour

Hydraulic oil for the crane operation - possible, maybe black but not usually, but would most likely the leak would continue while the crane was operating. Did it do this?

Engine lubricating oil - this would be black, if an ongoing leak the engine will obviously run out of oil. Warning lights should come on before any damage though, as the pressure drops. Has the crane engine recently been serviced and had an oil change? Has some oil been spilled during the servicing and become trapped in the structure of the crane and has finally found a way out and on to the ground?

Wash fluid - similar to above has the crane recently been jet washed, and trapped liquid dripped on to the ground?

As with others - get the fluid tested if its not obvious, more info required.

It is not clear to me if your organisation manages this crane, or if it is hired. Either way, I would formally request that the responsible person / engineer investigates this and provides a written report - then go with what it says. You have to rely on the expertise of others where you do not have it. I speak as someone who knows little about cranes but have managed safety where various types of crane operate.

I agree that the crane should not be used until you can be 100% sure that the leak is not going to affect its safe operation.

I agree with Pikeman. Formal request to get it looked at, detail the safety reasons why it should be looked and ask that it is not used until this has been done. If you are in control of the crane that should be easy, if not then I would document it.

Joe, if I was in your shoes, I would be doing the exact same things as you said in #1.

A lot of speculation when you have not said what type of crane it is . There is a distinct possibility that it has 2 engines and this is an oil leak from the crane driving engine as opposed to the engine used for lifting. As it is black oil it would be more than likely oil.

Is it yours? If not contact the crane company.

Does the operator not know?

Dont use the crane if in any doubts to its safe operation. Consider swapping the crane if possible. You will always have the commercial pressure to deal with as well I understand.

Speak with crane hire company or even your insurance company as if you have hired the crane it will be on your insurance.

It could even be gearbox transmission oil rather than engine oil.

Either way, get it checked.

Hi All

Guys I was not meaning to be tight in giving out the info , the crane is Liebherr 11200. As Pikemen and Ashleywillson say I have already formally requested assurances that the capacity of the crane has not been compromised ( this I made sure went to high authority within the organisation) to my line management and site management.

I have received a 6 sentence email from the crane owner that yes this is a culmination of rain water which gather under various trays beneath the carriage section and when de rigging the levels wash out.They are a lifting company working under our plan and PC role.

So its safe to say then, that lets say for example they rock up to Stanley or Sellafield for a job , they must remember to say

"Well yes we a 4 million euro machine that will do the job and we are fantastic, however please don't make a fuss that we leave a 5 x 5 meter mess every time we have derig ?"

Sorry guys I wont have it, Yes I have pushed very hard with this and very content with my discussions and documented emails to the very people who I would hope realise that maybe we should have a look at this, but only after we meet the target lifts which they already have done anyway !!

thanks again for the replies all much appreciated. we can close this one out.

Well done Joe dig in on this one it is the biggest mobile telescopic crane on the market at the moment .
It has 2 engines but it stinks what you are being told so good luck.

At the very least the hire company should have sent a technician to investigate a suspected leak which may be coming from one of many areas, engine, gearbox, transmission, axles, hydraulics, fuel, coolant etc, etc, etc or possibly could have been blown out of a breather if overfilled as one of the other respondents has suggested. I doubt if the leak is hydraulic oil if you say it is black but there are some types which are dark red in colour. The operator would have, or should have checked the sight glass on the reservoir and any other fluid levels? As a side point a loss of hydraulic oil will not cause an uncontrolled descent of the load as this failiure mode is normally prevented by various lock valves in the hydraulic system, on a modern crane I would also expect a level sensor to be fitted to the reservoir which can either give an alarm and/or disengage the pumps or transmission,shut down the engine or a combination of these controls.
