    We have two different winch systems one circa 1964 and one circa 2000.
    Both systems are broken down  and stocked as serviceable assemblies namely drive, gearbox and drum where each can be serviced jointly or independently depending on the available servicing window. Also where the servicing window is very short we stock a complete winch assembly and simply change over the cable. With our 1964 winches this is not possible as they utilize a single drive system which is shifted to the either of the two winch drums, as a result the servicing intervals are much longer.
     
    We have designed a replacement winch system for these older winches that take into account our knowledge and experience of our decoking system operation as well as the recommendations of a detailed Reliability Centered Maintenance Study.
    Generally both systems are quite reliable if properly maintained, although we have run into a reliability issue with the Flowserve   I-R winches if the band brakes are not properly maintained, in that the drive shaft as it enters the planetary gearbox is prone to fracture if only the motor disk brake is functional.
     
    Because our cokers are on the front end of our operation and supply all of the feed for the operation we tend to stock what seems an excessive amount of spares.

    The delayed coker I worked a couple of years ago had four  I-R winches (2000). 
     
    We had the same drive shaft spline failures. It was a good thing we had a free fall arrestor system.
     
    For spares we had a complete “non-warehouse” spare winch. This was a “non-warehouse”, because it was mounted on a skid and used to lift or drag loads in the plant.

    One more thing. In a coker, it is good to have all the spare parts you can get.

    If you can supply the maunfactures name and model number of the hoist I might be able to help, we have I-R FA-5’s air/electric hoist; I stock 1 complete hoist, 2 directional valves , 1 brake assy, 1 volume booster and many versa valves. also it a good idea to have a spare roll of cable JUST INCASE you have a failure

    We (Valero Texas City) have the F5A-DCOKR IR winches with four years on them and no failures yet. We plan on shopping all of them at our T/A next year. “RAM Winch and Hoist” will be our shop in Houston. They make a DCOKR winch of their own with superior materials and design. Best of all they are cheaper to buy from and actually stock them on site
    Saw 3 in stock yesterday.

    Can somebody help me with winch wire rope inspection ? When do you replace wire rope ? No free fall arrestor.
