TEETH

D-7685 Teeth 

Teeth are used to help a bucket dig better, the teeth help the bucket penetrate the material.

Teeth come in three basics types Weld-on with replaceable points, Bolt-on, and Weld-on. The type Anvil uses on their bucket depends mostly on bucket style and some on customer preference.

REEVING

Anvil's RN Round Nose Dredging Buckets can be designed with the option to be "Short Reeved".  This allows the customer to remove sheaves which shortens to cable required to closed the bucket which in turn increases the speed of operation.  The negative of removing sheaves is that you will lose the mechanical advantage of the removed sheave and lose closing power.

Short Reeving is typically done when handling lighter materials that do not require as much dig force.

MATERIAL UPGRADES

Bushings

ASTRALLOY PINS AND MANGANESE BUSHINGS

*INCREASE PIN AND BUSHING LIFE UP TO 60% LONGER THAN STANDARD MATERIALS

  • Astralloy Pins with 11-14% Hadfield Forged Manganese Bushings increases the overall life of the grab components. The lower wear rate will result in having to replace the parts less often. This will also reduce the stress cracking due to flexure.
  • The bushings will survive in harsher environments. A standard 4140 bushing when worn enough can crack in the right scenario, a manganese bushing will not exhibit this weakness.
  • This upgrade option can increase the life of your parts by up to 50%. 
  • MANGANESE BUSHINGS
    • Typical Hardness After Work Hardening: 500 Brinell / 52 Rockwell C
    • Where Used: All rotating points except for sheave bushings
    • Pros: Will not break/crack, extensive wear properties keep this bushing in use far longer than 4140 bushings.
  • ASTRALLOY PINS
    • Yield Strength: 153,000 PSI [1,055 MPa]
    • Tensile Strength: 175,000 PSI [1,207 MPa]
    • Hardness: 320-380 Brinell / 34-41 Rockwell C
    • Where Used: All pins, except sheave pins
    • Pros: Upgraded steel for pins. Improved strength and wear properties overall compared to 4140

 *NOT AVAILABLE FOR SHEAVE PINS DUE TO HIGH SPEEDS

 420 STAINLESS STEEL OVERLAYED PINS

  • Typical Properties:
  • Hardness: 500+ Brinell / 52+ Rockwell C
  • Where Used: All pins except sheave pins
  • Pros: Ultimate steel for pins. Incredibly high strength and wear properties, where these pins combined with manganese bushings can virtually run greaseless.

 *NOT AVAILABLE FOR SHEAVE PINS DUE TO HIGH SPEEDS

 HARDWARE500 PLATE STEEL

  • Tradename: “AR500”
  • Typical Properties:
  • Yield Strength: 200,000 PSI [1,379 MPa]
  • Tensile Strength: 225,000 PSI [1,551 MPa]
  • Hardness: 480-550 Brinell / 50-54 Rockwell C
  • Where Used: lips, bowl bottoms, sides, wear pads, etc.
  • Pros: AR500 has the best strength & wear properties when compared to other steels.
