      I have a new toy, an HBM BF28 milling machine. I managed to get it into the apartment with difficulty, but I don’t know how I would lift it onto a table. It weighs about 130kg. Where I live now, I don’t know anyone who can help me lift it. I could dismantle it as a last resort. But I’d rather not do that. I have a few ideas for lifting it in several stages. But they are too dangerous to mention here. How would you do it?

        If you can’t use a hoist or similar, it might be best to split it into 3 parts.

        I did that when I bought my Warco wm16 secondhand and it was in an upstairs workshop.

        I removed the table in one piece and the head also in one piece. I supported the head on some wood on the table and then removed the retaining bolt.

        I found a you tube video at the time where someone showed how to do it.

        This is a post I made a while ago about a similar question

         

        I have a Warco WM16 mill which looks to be the same design as the Chester 20v

        I bought it secondhand and it was in a first floor workshop with access via a narrow staircase.

        I split it into 3 parts to move it.

        I removed the head in one complete part with just 3 nuts/bolts to remove. I watched this video on you tube to see how to do it. https://www.youtube.com/watch?app=desktop&v=1CzlveOjWiEHe went over the top making a block to hold it. I just lowered mine onto a block of wood on the table. 

        Then I removed the table just leaving the base and column together. I removed the complete x/ y table by winding it forwards. I had to remove the lead screw nut from under the table . It was held in place by 2 screws, accessed from the back. This is the heaviest part but one person can lift it though best with 2. (My son in law moved it from my car to my workshop on his own before I had chance to help!)

        Myself and previous owner carried the parts down the stairs between us without any problems.

        So you should have no trouble doing the same.

        You can download a manual from the US site of Grizzly tools which looks like the same design. https://cdn0.grizzly.com/manuals/g0704_m.pdf

          All my machines have to be moved to the first floor using a small stairway. So I must take the machines apart and even then, it is a tough job. My latest mill (F207-V) is moved in 4 peaces.

          These Chinese machines (I have 4 of them) need a full service right out the box and also a full adjustment. That is good to combine with the assembly.

          Don’t lift the milling machine by the head. All forces will be applied to the Z-axis nut/spindle and it could be damaged doing so.

          If you want to take the head off, there is a grub screw (not on drawings) at the right bottom of the head, hidden deep in a not fully threaded hole.
          Place the head on a piece of wood before you loosen the 2 nuts and use the X-axis to pull the milling head off. Mill a pocket for the spindle end and pinole depth gage to avoid damaging these.

          If you take the Z-axis apart, remove the paint in the nuts before you place the wrench. The 4 bolts can be very heavily torqued.

          If you have the Z-axis laying horizontal on a table, it is easy to adjust the z-axis gibs.

          To mount the z-axis vertical you need a large (100+ mm) granite square or angle block and an indicator mounted on the Z-axis slide.

          Once the Z-axis is mounted square, you can mount and adjust the milling head.

          The z-axis is probably not square in the X-Z plane. You can use a 400 grid diamond sanding block to get it straight. Give it 1 stroke at the top or bottom half of the mounting planes to get it square. You have to do this a couple of times to get it within 0.02 mm/100 mm. After each stroke with the diamond disk, you have to mount the Z-axis and check the squareness in X-Z direction.

            I took the column/head off the base of two of my machines and it was then a fairly easy 2 person lift for me and my 80yr old dad. The CNC I used an engine hoist.

            If you don’t want to take it apart and there is noboby else then working your way up with “cribbing” if done correctly should be safe.

              ‘Break-down’ a 1t. engine crane, carry into apartment and re-erect.

              Buy or hire.

              Do not let the neighbours see.

                Hi Sonic Escape, maybe you could hire something like this Hydraulic platform lift

                Regards Nick.

                  Sonic asked how he can do this on his own without dismantling the mill.

                  Possibilities:

                  • Dismantle an engine crane to get it into the flat then do a conventional lift.   A safe one man operation provided an engine crane can be deployed. (Cranes are easier to reassemble than mills.)   OR
                  • With the mill secured on a platform, perhaps the pallet it was delivered on, jack the platform up in stages, building a stack of wooden baulks underneath to support the mill between lifts.   Risky, so proceed with caution.  Mills being top-heavy are liable to topple and have to be jacked evenly whilst secured to a wide base platform.   Equipment: a supply of fence posts and 4 car jacks,  maybe rollers to help slide the mill off the stack into position on the bench. (I’d lever it across a bench, only has to be lifted a millimetre at a corner to swivel it into position.)

                   

                  Jacking lifts are common in Civil Engineering. Done with levers In the olden days rather than jacks, but that breaks the Sonics rules because a team is needed, ideally 4 blokes levering whilst № 5 coordinates and inserts baulks.

                  Note the right abutment of Brunel’s Saltash Bridge is being built up under the span in stages to support a jack, and, then the whole span when the lift is complete.   Also common for the supports to be temporary timber.

                  New word learned from Jason this morning: this is called ‘cribbing’.

                  Just in case a literal minded friend thinks I’m suggesting lifting a mill on a stack of matchsticks, this is only an example:

                  DSC06895

                  6 grams of matchsticks easily support a 720g battery:

                  DSC06896

                  And if it’s not obvious, the stack doesn’t cope well with sideways forces.  Take care!   Even if it doesn’t crush Sonic, a falling mill will probably damage the floor, alarming the neighbours and annoying the landlord.

                    Hi, Brunel’s Saltash bridge, I went over that and back again, during the fourth week in September 1975.

                    Those match’s are a fire risk, I mean, you could accidently drop the box. and SOD’s law the side of it would strike one of them. (sorry Dave, I couldn’t resist that one)  (Smiley)

                    Regards Nick.

                      Another traditional way of heavy lifting is to improvise a lifting tripod. You do need emough headroom. Material can be rough timber and rope, and it may need tethering round the base to prevent outward slippage. Needs a bit of cunning to ensure the load can be pushed sideways onto the bench etc., or it may be possible to”walk” the whole thing into position.

                          Well … the thirsty blokes tend not to speak English and my Spanish is not good enough yet 🙂

                          About the table. I don’t have one strong enough. Normally I would build a workbench myself but here I don’t have any tools yet. And anyway playing with angle grinder or welding in the apartment is out of the question. So I’ll have to buy one. But a solid workbench could be quite expensive. Even a used one.

                          I found this model that has a more decent price. But I’m not sure how solid it is. In the specs it says it should hold up to 900kg. But how about the rigidity? Afterall the legs seems to be attached only with two screws each. And I can’t see one before buying it. Anybody had any experience with this kind of workbenches?

                            I’ve just had to build a bench to stand a smallish mill on – I used a really flimsy small pine table (because I had one) and boxed in the sides and supplemented the top with ply – it’s very rigid.

                            How about Ikea.?
