We have four of them. Two wide and two narrow. We used them on Volvo L70's but they can hook to most equipment. They are hardly used. These are the top of the line quarrying forks. They are from SAS Forks. Here is some info for the description:
SAS quarry forks are designed to sustain repeated impact while quarrying dimensioned stone. Specially reinforced carriages and forks provide the durability required in a rock quarry.
Prying and chiseling of cut or blasted stone:
Forks designed to maintain 100% of breakout force* of machine.
Fork carriage utilizes T and double TT to absorb impact and disperse it throughout machine to lessen absorbed shock.
SAS Quarry forks have an added 500-1,000 lbs. of lift capacity over competitors.
Zero down time goal, SAS forks have been field tested with NO fork breakage.
Engineered and built for optimum performance:
SAS Quarry Forks carriage built completely of high tensile steel for optimum durability and life.
Solid Steel forged fork 30% stronger than T-1 material
The wide ones are 5' long and 37" wide.
The narrow ones are 5.5' long and 28" wide.
