My poor and hungry (P&H
for you who haven't heard that one). We've had this crane a couple years now. The above job has been a great job for it. It has 126' of main boom (4-section, remote power pin), with a 60' jib (swing around and pull out). From the top side of the above building, we need all the boom, jib and offset, to fill in the inner iron.
Its a 1987- t 650, weighs about 93,000- 10' wide carrier, 14.00r20 main rubber. It came with a boom dolly, I decided to get rid of that and add the tag axles. There's one on the rear, and a pusher in front of the tandems. I could really scale with only 1 of the 2 tags, if I could get the weight exactly where I wanted it. But I added both because I wasn't sure I could get my weight equalization right with only the rear tag, or only the pusher in front of the tandems. This way I only need to get around 10,000lbs on each tag.
The tags are both air suspension, rear tandem is walking beam, front steers are spring. It actually rides and drives much better with the tags, than it ever did with the dolly. It's way easier to get around corners too. I actually could only leave my shop driveway and head one direction with the dolly, if I went the other way, the road cambered too much, and I'd spin out. It actually rides better than my 3' axle 25 ton's do.
Almost forgot- that's right- DETROIT DIESEL -6v92 - If only I could post sound pictures.
