Walk-Through Table Truss Building System

The fastest, easiest,
safest way to build
roof trusses
Proven by literally hundreds of plants across the country. Some 800 to 900 new Walk-Through™ tables are now being installed annually in component manufacturing plants across the nation. Literally hundreds of plants have switched to “feet on the ground” truss building that their Walk-Throughs make possible. And, to our knowledge, not one has gone back to building trusses with “climb-on-and-off” solid-top tables. Indeed, it’s our customers that wrote the “fastest, easiest, safest” headline atop this presentation.
“It goes faster
That’s easy to see. But it goes consistently and predictably faster which is what makes the difference to our bottom line.”

“It’s much easier
There’s no jumping on and off tables, working stooped over or on your hands and knees. Fatigue takes its toll … daily … and cumulatively.”

“It’s a lot safer
There’s less risk of trip & fall accidents and far less wear & tear on the builders.”

In truth, “faster, easier, safer” hardly tell the MiTek Walk-Through story. And the words can ring a bit  hollow until you see the facts behind them.

The facts behind them
Faster Facts
  • No time lost jumping on & off tables to assemble parts & plates … or to retrieve tools, parts and jigging that fall off. No time lost lugging lumber, plates, and tools up.
  • No time lost moving cautiously atop tables to avoid tripping on work or jigging or tools.
  • No time lost stooping over and kneeling down.
  • No time lost waiting, no “hand me that” delays – everybody can be on task throughout the process.
  • No time lost positioning plates – better visibility from waist level.
  • No time lost tacking plates – a single full-face hammer blow is typically all that it takes when the work is at waist level.

Easier Facts
  • Bottom plates can be positioned and tacked off-line on webs and bottom chords. Much easier than trying to position bottom plates that you can’t see.
  • No hammering at awkward angles – hitting plates with the edge of the hammer head, bending and distorting the metal. Tacking while the work is at waist level makes for a better hammer angle (full head surface meeting plate) and less off-target blows.
  • No stooping down on top of the work means hats don’t fall off, safety glasses stay in place, pens and the like stay in shirt pockets.
  • Overall, less steps to do the same thing.
Safer Facts
  • Less accidental injuries from jumping on & off tables, no tripping on pucks or parts or tools.
  • Less risk of serious/fatal press accidents – simply because there is little to no time spent on the table in the risk zone.
  • Back, knee, and other bodily “wear & tear” injuries – a consequence of continuously jumping on and off tables, hunched over, kneeling down, and working in awkward positions – are all but eliminated.
  • Cuts and punctures – suffered while hand-carrying connector plates up & down from the table or trying to position them while working at awkward angles – are minimized. Very importantly, excessive fatigue – a major factor in many mishaps – is substantially reduced simply by staying on the ground.
Better Quality Facts
  • When builders are working more comfortably – not continually working in awkward positions – the quality of their work naturally improves.
  • When you’re able to tack the majority of bottom plates off-line while the part
    is face-up, plate locations are “dead on” – builders feel better about their work, plants satisfy the more stringent TPI quality control standards forthcoming.
  • Properly located and tacked plates mean the roller press will consistently seat plate teeth properly – without teeth curling and rework. 
   For all the increased
   speed, ease, and
   safety, there are
   no compromises
   in quality.
   Just the opposite.
The bottom line
with Walk-Through tables is …

Your bottom line
  • Consistently faster building means less labor cost per truss and quicker turnarounds.
  • Reduced accidental injuries and wear & tear injuries can mean reduced Workers Comp premiums, reduced health insurance costs, less sick time, and no extra expenses for knee pads, back supports, and other assists.
  • Less fatigue means improved builder performance.
  • Consistently higher quality jobs means more pleased customers … and more jobs.
Walk-Through™ Table with Steel Slotted-Top

It works like this.
This is a simplified explanation of the most common Walk-Through table build method.
Build methods may vary.
1. Position & view truss
      Determine best truss-build
        location by moving truss
        image on screen – back &
        forth, up & down, rotate,
        flip over. Avoid positioning
        trusses with joints falling on
        aisle spaces and ejector
        channels. To minimize
        movement of jigging pucks
        from truss to truss, consider
        other trusses in the production
        run before final positioning –
        images can be see-thru layered.
2. Position & Quick- Lock
      Jigging Pucks
      Print out setup sheet and
        quick-lock the pucks (quarter
        turn of wrench) into their
        called for positions. Add
        jigging fixtures as necessary.
3. Put top chords in place
4. Put webs in place

5. Position Aisle Pads
      and Ejector Pads
        Place wherever a connection
        point is located over an aisle
        or ejector channel.
6. Make sure all bottom
      and top plates are
      in place and tacked, 
      position and plate
      bottom chord.
      Bottom plates can be positioned
        and tacked on both webs and
        bottom chords off-line.
7. Press – Initial Roller Pass
Built to take it. Indefinitely.

All Steel Construction – 5600 lbs. (approx.)
Four 10” lengthwise steel-channel beams, three 8” vertical steel-channel supports, and 1/4”-thick 4x4 “angle iron” internal bracing.

Absolute, no-flex rigidity – provides rock firm foundation for
full-force press. Truss builders will feel the difference.

Quad-braced, 3/4"–Thick Fitted Aisle Pads
Recessed table lips support Pad to assure full-force press on
plates located over walk-through aisles. Half-sectioned for
easy handling (42 lbs.).
1"-Thick Ejector-Channel Slider Pads
Recessed table lips assure full-force press on plates located over ejector channels. No lifting – slide back & forth.

1/4" thick steel
Height adjustable 4 1/4” – from 31 1/4” - 35 1/2
Six Full-Table-Width Jigging Slots
Tight 8 3/4”-on-center spacing allows placement of pucks and
fixtures just where they’re needed.
Tekset Jigging Compatible
Slip in slots to position and hold just about any type
of joint, any truss configuration. Simply the most flexible,
easiest-to-use pucks & jigging fixtures available.

Center-Mounted Lifter with Ejector.
The air actuated ejector lifts the pressed truss above jigging pucks
and fixtures, then moves the truss off the table. Select Side-Eject,
Auto-Eject or End-Eject option.
Gantry Rail
Roller press rides on rail -- no track to trip on

Simple Installation
3/8" Steel plate anchors full-face to floor along table length, table legs anchor to steel plate. Exceptionally secure
anchoring with minimal installation. No extra charge for installation supervision and technical assistance.
