seeking advice on moving PDP 11 and related gear

I think there's a lot of good advice here ... as others have discussed, the greatest consideration for you will likely be the weight and dimensions ... the 11/34a is a "4-6U" machine but it is much heavier than any 4U machine you will see nowadays, and the weight is not evenly distributed in the chassis; it's mostly in the rear with the big transformers and capacitors in the power supplies ... if I had to guess from dragging and carting mine around, it's probably somewhere in the neighborhood of 150-200 lbs with a full-ish board complement ... I can drag it and lift one side or the other, but I can't really pick up the entire system by myself ... I don't have any RLs but I suspect they are similar in form factor to the CDC Hawk fixed+removable drives that I have seen and helped someone move; again; these are at least "4U", "full-depth" devices that can each weigh a few hundred pounds ... A lot of these older drives can have head locks for shipping; if applicable; make sure that the heads are parked and locked and I believe you'll want to ensure there is no pack in the drive while it's being shipped. Last summer, I did my largest ever equipment move which included a ROLM CBX and two Harris D1200 PBXes. The ROLM was ~1 ton and probably the size of two and a half DEC "low boy" racks conjoined; the Harris switches were in more standard 19" ~42U racks but components were placed with a ridiculously high CG ... maybe a half ton each ... Here's what I learned: 1. You will wish you could just pull up to a loading dock; you had a liftgate truck or that the seller has a forklift on their end. Regardless of how "low floor" the truck is, and depending on where the center of gravity of the racks you are trying to load is, wheeling fully loaded racks up a U-haul ramp can be very challenging ... The guy getting rid of the switch and I just barely got the ROLM pushed up the ramp into the truck ... we were sweating it pretty hard ... and he was a fairly experienced mover of heavy gear and knew some special moving tricks ... I don't think we could have done it without his knowledge (without two or three more guys to help push, at least). The guy with the Harris D1200s had a forklift on his end and it was awesome! We got those two things in the back of the truck in no time flat. Just lift em up and pull em in the back! Try to conscript at least one ... two or three would be better ... friend(s) ... to come along and help move, also taking into account the abilities of the guy at the other end to be willing and/or able to help you out ... thank goodness the guys I was working with were both, and it saved my butt ... Do bring a few very stout wood blocks (i.e. chunks of 4x4) to chock the rack mid-way up the ramp while you figure out what to do next, catch your breath, regain your footing, etc :O Bring any moving tools you might have that could help; a small winch, dollies, come-alongs, bottle jack, plenty of strong rope, etc. Consider ahead of time what you might do in the worst case; what if the wheels of the rack, don't fit within the footprint of the ramp? What if the rack gets hung up on the "lips" on the sides of the ramp while you're trying to push it up? 2. You can ease loading if you can break down the racks a little bit ... but that takes time and a place to work, which the seller may not have quite so much of at the moment you stop by to pick up; as well, for this to be an option, you'll have to plan ahead to bring appropriate tools and some mechanism for documenting equipment positions, cable connections and so on ... digital camera and a pen and paper will be a big help if you decide to do this ... it can be worth it to plan ahead and pack a little bag to carry in the cab of the truck with some basic electronics tools (N-in-one screwdriver, a few pairs of pliers, dikes, maybe a small socket set; a Sharpie), your digital camera, pad and paper if you do start to have to get into disassembly to get the gear loaded. 3. I don't think it matters if you load from the front back, or load on the sides; when I did my move; I had loose vintage computing equipment piled up at the front of the truck, the ROLM was strapped to the left side of the box and the two Harris switches were strapped to the right side of the box; I piled up boxes of documentation binders and 25/50-pair cable coils in the middle of the truck and between the bolus of stuff up front to "pad it out"; IMO, the important thing is more that you position the racks where you can get at least three or four ratcheting tie-downs around each rack to points on the truck box; top bottom and middle; the more tie-downs the better, and wind them up tight! You will not believe how much this stuff can jump around in the back of a cheap U-haul with blown-out suspension when you're winging it at 70 mph down the highway ... anything on slides, or racks with doors, if you can lock them into position; do that; a few rolls of strong packing tape can also help hold things in place, especially rack doors where the lock keys have been lost ... When loaded, drive slow and easy as you can ... leave LOTS of space between the vehicle in front of you and take it easy on the turns! You don't want to slam on the brakes ... that one ton rack behind you has a lot of kinetic energy ... this leads me to ... 4. Be very mindful of delicate and hard-to-replace cables, especially, but also smaller ancillary items (i.e. terminals/CRTs, disk packs, tapes, spare boards, workstations, whatever) to position them where, if the racks do start moving around, the smaller items are protected from crush and slice damage ... the edges of the rack and the floor and sides of the truck form a very effective shear or brake when brought together with great force... I had the ROLM jump around on me a little bit in transit and it took out a Sun monitor positioned nearby in the back of the truck! Maybe carry some of the smaller, most fragile stuff up in the cab :O It can help to bring a little "dunnage" in the form of some old cardboard boxes, bubble wrap, styrofoam chunks, whatever if you've got some of that laying around from recent eBay purchases or something (I like to keep this stuff and re-use it). 5. Bring lots of money for gas! Once you get a few tons in the back of that truck, you will literally get 5 MPG or less ... :( 6. Unloading... don't let your extra manpower go until you've got the gear off the truck! Unloading is a little easier than loading thanks to gravity but the more people you've got on deck, the more controlled a fashion you can get the racks off the truck. Consider dimensions ... I was just unloading to my detached garage so no biggie for me ... or if you have a walk-in basement ... but you may find some trouble fitting this stuff through a standard residential door; if this is the case, it's nice to have somewhere to keep the gear out of the elements while you break it down into smaller chunks that you can "digest". There are plenty of experienced guys here who have probably moved much larger loads than I; once you're through with this thread, I think you'll be in pretty good shape :O These little "expeditions" can be hard work but also quite exciting and great fun.
