1980s MAC Corporation Car Crusher

[StakerAlloys8]

They have made MAC car crushers since the 70s, and at that pretty much unchanged. The only things I have noticed is the switch from a Detroit Diesel 4-71 to John Deere and Cummins power sources, Dayton Spoke wheels to steelies, and the removal of the cab, besides that they're pretty much the same. 

 

Me and my dad built this one based of a either 80s or early 90s MAC car crusher with a 4-71 Detroit. Some came from the factory with a 4-71T, or turbocharged 4-71. I didn't have of those, so we did the rational thing and used a 8v71 out of the GMC General kit. Which is basically two 4-71s put together. If a 4-71 can feed the hydraulic pump enough to crush a car in 40 seconds, then a 8v71 could probably do it in about 20. Not overkill at all!

The base is the AMT furniture van, engine from a GMC general, Rims also from a furniture van. Oversize load and grille decal from the bulldozer and the rest is either kitbashed or scratchbuilt. 

It rained so I couldn't get pictures on the blacktop. 

 

Thanks for looking!

The crusher looks amazing.

Would fit perfectly on a junkyard diorama!

Thanks Alan, from my own guesstimation people are more familiar with E-Z Crushers then MAC Corp crushers.

Really? Well at least you know what a MAC Corp crusher is now!

 

They sure are impressive machines, wait till you see an E-Z log baler! Its a pretty neat piece of equipment.
