Specifications of the MaxJax

You'll notice as you go through the specifications of the MaxJax™ that we over-engineered every aspect. Our engineering team spent close to two years meticulously getting the most strength out of each measurement. No corners were cut in the making of this product.

    • Floorplan & Baseplate

    Wide or narrow installation is possible - the MaxJax™ auto lift can be installed at a width that suits the vehicles you will be raising. You may even choose to install additional anchors at varied column positions for adaptability to multiple vehicle configurations. The baseplate measurements should be used as a reference only.

    Anchor Bolt Stress Analysis

    Just how strong are the anchor bolts used for the MaxJax™? Here, we'll tell you exactly. In an effort to show just how safe the anchor bolts are when properly installed, our engineers performed stress analysis tests on just the three back anchors. Although we recommend using all five anchor bolts, we wanted to make sure there was no chance of failure when properly installed in concrete.

    Analysis: Base plate anchor bolts (3 on outside edge) in tension. Analysis was performed using published Allowable Stress Design (ASD) "Design of Base Plates"......"Moments of Large Effective Eccentricities" formulas and procedures.

    Formulas:

    fp = 0.7 x fc

    e = M/P

    f1 = fp x B x N1 / 2

    A = f1+/-(f12 - (.667 x fp x B) x (PA1+M)).5 / (fpxB/3)

    T = (fp x A x B / 2) - P

    T per bolt = T / # bolts

    Safety Factor = Ultimate Bolt Strength / T per Bolt

    Design Factors:

    Fc = 3000psi (Strength of concrete)

    # bolts in tension = 3

    Anchor Bolt Ultimate Strength = 12,580 lbs. PD58, 5/8" Wej-It Drop in Anchor, installed in 3000psi concrete per manufacturer's instructions.

    Compressive Load = 3383 lbs. (3000 lbs. lifting + 383 lbs. lift assembly weight)

    Moment = 124598 in-lb (per ALI B-4 lift diagram arm extension at rated load)

    Moment = 138549 in-lb (with fully extended arms)

     

    Results:

    Tension stress per bolt = 2,838 lb tension, loaded per ALI B-1 diagram.

    Tension stress per bolt = 3,238 lb tension, loaded per Arms Fully Extended.

    Safety Factor = 443% (based on ALI B-1 arm extension)

    Safety Factor = 389% (based on fully extended arms perpendicular to the lift)
