GENERAL SCRAP GRAPPLE OPTIONS

NARROW BLADE tines are used when handling large scrap pieces.  The narrow blade design allows for superior penetration of the material.

LOWER 1/3 ENCLOSED tines are good for handling smaller pieces of scrap or finer materials while maintaining a lower grapple weight and maximizing the capacity of fine materials which can be handled by the grapple.

LOWER ½ ENCLOSED tines are similar to the lower third enclosed, except the liners are enclosed for half of the way along the tine. This increases the grapple weight more than the lower third enclosed liners.

FULLY ENCLOSED tines are used when handling small pieces of shred scrap or other loose material.  A fully enclosed grapple allows the grapple to be used as a bucket. They are like the lower third and lower half but fully enclose the entire tine. This increases the weight even further past the lower half enclosed liners.

QUICK CONNECT TINES

Quick Connect Tines allow for fast and efficient changing of tines in the field.  This option is most often used when the types of materials handled changes frequently.  The grapple can be configured for narrow blades for scrap and fully enclosed for ores.

MATERIAL UPGRADES

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.
