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.

BOLT ON COVERS / ENVIRONMENTAL COVERS
 
BOLT ON COVERS
 
Bolt on covers are sometimes referred to as environmental covers.  These covers are used when handling dusty materials which should not be released into the environment.  They further close in the top of the bucket to help keep dust contained.

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.
CLUSTER SHEAVES
 
cluster_sheave_assy
 
Anvil's patented (Patent No. 7,607,643) Cluster Sheave assembly extends cable life up to four times over traditional fairlead designs.  This saves on the cost of labor and material when having to frequently change damaged cable.
 
Traditional fairlead designs force a round cable through a square hole, Anvil's Cluster Sheave design increases cable life by running the cable through four sheaves on bearings allowing smooth cable operation.

CLUSTER SHEAVE ASSEMBLY

BOLT ON EDGES

Edges are used on buckets to protect the bowl lips from wear.  Bolt on Edges are the most common edge Anvil sells.  These edges are a proprietary cast material to the equivalent of AR400.  They are pre-drilled and come in various thicknesses and lengths.  Anvil stocks these edges and when ordered they are cut to the required length. 

These edges are reversible: when one side has worn down, the customer can unbolt them, flip them over, and use the other side.  When that side is worn, the customer will have to order a new set. 

Anvil uses Stover lock nuts to secure the edges.  These nuts have proven to be the most secure and reliable.  Once the customer unbolts these nuts, it is recommended to use a new set of nuts.

BOLT ON / WELD ON EDGES

Bolt-on Seal Lips are used when the customer will be handling small/fine materials which the customer does not want leaking from the bucket alongside tougher, rough materials that could cause a lot of wear on the lips. Anvil’s bolt-on sealed lips are interchangeable with the bolt-on edges.  This gives the customer the flexibility to use the bucket in various types of material.  Anvil currently has a patent (9,388,023) on this bolt on sealed lip design.  We offer two types of rubber gasket for the sealed lip depending on the material being handled.
