Hello Tom, 

Attached are three pictures showing the RICH with its lifting tool in an isometric, top, and side view. 

Best regard,

Suresh, 

I believe the max load would be 1500Kg (includes the loaded detector and the stiffener), and I think the load test would be 125%.

Marc, 

What is maximum load that the device is to lift & for what load the load test is planned?

Hi Rusty and Suresh, 

Our collaborators from INFN (Italy) are having an "under the hook lifting device" fabricated here in the US at one of the Jlab procurement approved welder/fab shops. Below is the information I got from the EH&S manual on requirements for a device to be used here at the lab. 

Due to cost, they will probably have the load test done by Hall B Mechanical/Engineering and I have asked them to have the final design reviewed by Bob Miller to make sure that the design passes Jlab standards. 

Is there anything else which would need to be done that I might be overlooking? 

I have attached the .pdf of the preliminary files INFN used for RFQs. 

Regards, 

Marc

Marco, 

I am not sure if you are going to wait for any further quotes before going forward with the selection. But, when you ask the vendor to "re-quote" to satisfy your requirements, the vendor will need specific details about information/documentation you need in your final quote (Or they will just send the same quote). 

Doug has provided some information to help us fulfill some of the Jlab requirements for approved use at JLab. In his email, he is referring to specifications that need to be followed by the designer and fabrication shop: 

    * The shop was selected from the Jlab approved fabricators list for welding/brazing. 
    * A qualified Professional Engineer (PE) must approve/design the "Below The Hook Lifting Device" in accordance with ASME B30.20, ASME BTH-1 . 

        * When requesting the requote you should ensure that the fabrication shop meets these criteria 
        * You may want a JLab PE to review the drawing, prior to manufacturing. 

            * Bob may be able to review (If he has not already done it) this if you can provide him with the final drawings (after parts have been converted from metric components to the closest English standard) 
    * 
The fabrication shop must label the device with the following information: 

        * Manufacturer's Name 
        * Manufacturer's Address 
        * Serial Number 
        * Lifter Weight, if over 100lbs (45Kg) 
        * Rated Load 
    * 
We will need to do a load test at Jlab or the shop will have to do it and label it as such. 

        * We should ask the fabrication shop how much this would cost, maybe it is not expensive. 
        * Hall B is qualified to do this test 

I will try to find out if there are other requirements or documentation needed for the stiffener. 

Thanks, 

Marc

Not if it is done by a PE. It will need all the under hook paperwork

Hi Doug,

So far all we have done is contacted fab shops for quotes. We asked Bob for advice on getting a better price, and are following his suggestion, he also suggested having the load test done here at the lab, should CE be contacted prior to manufacturing?

Thanks,

Marc

I guess you have contacted Civil Eng about a Under Hook Device review and inspection and load testing?
