Design of a clamping teeth

  1. Dec 13, 2009 #1
    Dear All,

    I am designing a clamping teeth for a clamping device.
    The clamping device is to pulling I beam pile from the ground for recycling mounted on a hydraulic jack.
    I wonder how could I determine the depth of the teeth, number of teeth and the angle of teeth. As the teeth will grab into the I beam and leave a permanent grab mark, I wonder what design guide I can follow.

    Seem it related to energy method, am I correct??

    Thanks for your kind help

    Hi, Su.
    Does it have to be teeth? I ask only because I suspect that non-slip pads such as a silicone compound might be more appropriate.

    I am reference to the clamping teeth of a Casing Vibrator which use high carbon steel.
    The pulling force would be around 10 ton + friction.

    I see. That's a lot bigger scale than I was thinking of.

    Since the clamping method is destructive (which is a quite rare method), I wonder how would be the calculation rather than copying the stuff from an existing clamp.

    I'm afraid that I have to bail on this conversation due to a lack of competency. Good luck with it.
