Camming head objective

Camming Head Objective

  • Fill width of crack

  • Prevent slippage of device when loaded

  • Hold Fixed Under falling situation Dynamic Load of 13KN


Camming head function

Camming Head Function

  • Maximize Frictional Forces By Optimizing Head Shape

  • Maximize Working Surface Area

  • Maximize grip of Head to Rock


Constraints for material selection

Constraints For Material Selection

  • High Fracture toughness

  • High Strength to weight ratio

  • Ductile

  • Formable

  • Maneuverable


Aluminum 6061 t6

Aluminum 6061-T6

  • 6000’s Main Components of Magnesium and Silicon

  • T6 Temper Designation That Solution Is Heat Treated and Artificially Aged


Heat treatment

Heat Treatment

  • Magnesium and Silicon are dissolved forming a “Solid-Solution”

  • Elements fuse to become an alloy.


Artificial aging

Artificial Aging

  • Strengthening Mechanism Equivalent to Precipitation Hardening

  • Precipitate Will form around grain structure leading to fewer slip planes


Resulting aluminum alloy

Resulting Aluminum Alloy

  • Fracture Tough

  • Strong and light

  • Ductile

  • Formable


Alternative 7075 t6

Alternative 7075-T6

  • Lower Fracture Toughness

  • Higher Strength Weight Ratio

  • Harder Surface-Less Wear


Why 6061 t6 aluminum

Why 6061-T6 Aluminum

  • Softness Advisable

  • Experimentally better against slippage

  • More Ductile less chance of blowout
