I fitted a 3 stage mast on my forklift to allow it to go through a 8' door and have have ~6' of free lift vs the 2 stage lumber yard mast it came with. I bought a triple mast off a Hyster E50XL of about the same vintage as my H50XL. It mounted on rings around the axle, whereas mine has ears and pins that sit in slots cast off the axle housing. I scarfed the old ones off and made up some new ones out of 1 1/2" plate. They take a 50mm bushing. I also had to make and mount ears on the side for the tilt cylinders to attach. They are fabbed up from 1" plate.
New mast
Old Ears
What it needs to look like. This was back when I rebuilt the trans.
Pulled the mast to take measurements
Chicken scratch cad drawing
Burned off
Que 2 yr hiatus
Snag Wheeled off flush
Filled and ground where I gouged in with the torch. I wish I had used the AirArc instead. Everything was welded out with Lincoln NR-203MP .068 self shield fluxcore
Burned ears out on the electric eye torch. Slugged them 1 3/4 and bored to .002 over 50mm
Set up to weld. I love those Cruise Industries mag burning squares. Whipped up a couple bushings and length of pipe to keep everything square and spaced
Goose schitted on. That wire never looks like it ties in on the toes, but that's just a weird trait of T8 structural wire. I was a little hotter (240 amps) than I could have been, but it's not going anywhere. All 2 pass welded.
Tangled mess that always shows up when I start dragging leads and air hoses. And yes, it does require 5 grinders to do one little job. lol
Side ears. Sorry for the greasy camera lens.
Decked to height
Slugged 1 3/8 with a rotabroach
Positioned by referencing the main mounts and mast front edge. The rotabroach is my temp pin so I didn't have to make one.
Squirt some paint. I hope the gloss fades.
Now I need to reassemble it with new rollers and shims.
