Discussion Overview

The discussion focuses on the design considerations for clamping teeth in a clamping device intended for pulling I beam piles from the ground for recycling. Participants explore various aspects such as the depth, number, and angle of the teeth, as well as alternative materials and methods.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about the appropriate design guidelines for the clamping teeth, suggesting a relation to energy methods.
  • Another participant questions the necessity of teeth, proposing that non-slip pads, like silicone compounds, might be more suitable for the application.
  • A different participant references the clamping teeth of a Casing Vibrator made from high carbon steel, noting the significant pulling force involved (around 10 tons plus friction).
  • One participant expresses concern about the destructive nature of the clamping method and wonders about the calculations needed instead of replicating existing designs.
  • Another participant indicates a withdrawal from the discussion due to a perceived lack of competency in the topic.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus, as there are multiple competing views regarding the design of the clamping teeth versus alternative methods, and the discussion remains unresolved.

Contextual Notes

There are limitations regarding the assumptions about the material properties and the specific requirements of the clamping device, as well as the potential need for calculations that have not been fully explored.

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.
