  Our proven design allows the Model 838 to easily be converted for use as a 26" low wing jack, as a 32" Cessna 340/402 jack, or to the unit needed to accommodate a Piper Navajo/Chieftain.  Thus avoiding the cost of purchasing model specific jacks.
  
  When the need is for a versatile jack that can accommodate the needs of a corporate flight department or busy FBO, the Model 838 Universal should be your first choice.

  The ultimate in versatile heavy-duty general aviation jacks.  The Model 838HW does it all for the high wing Cessna owner and cost conscious FBO.
  
  The Model 838HW combines all of the strength and versatility of our Model 838 along with the necessary components to manage high wing Cessna aircraft such as:  172RG, 182RG, 210 and 337.
  
  Our innovative and original design allows the Model 838HW to easily be converted from a 26" low wing jack through the 32" and 38" levels to a 70" high wing jack.  This avoids the high cost of having to purchase model specific jacks.
  
  If you need a versatile jack that can accommodate the needs of a busy FBO, the Model 838HW is the ultimate choice.

• Model:  321
  Stroke: Single
  Capacity: 3 ton (6,000 lbs.)
  Range: 21 - 35.95 inches
  Applications: Ideally suited for low wing aircraft having an especially low ground to jack point dimension. This model has proven to be the preferred choice of Ballanca aircraft owners as well as many Mooney and homebuilt aircraft owners.

This model has proven to be the preferred choice of Ballanca aircraft owners as well as many Mooney and homebuilt aircraft owners.

This unit features the same proven base design as well as the incorporation of our dual-purpose pump handle stowage and stabilizer braces.  It also features a one-piece centering collar having a proportionately smaller outside dimension.  This keeps the unit as streamlined and as unobtrusive as possible.

As the hydraulic unit height is dimensionally smaller (19.0") the unit is only available as a single stroke pump.  However, this has proven to be of no significant disadvantage as the travel distance is proportionate to the throw of the pump.  

Due to the size, design and nature of this unit, it has proven to be exceedingly popular with owners and maintenance personnel performing maintenance, repair and fabrication on aircraft having minimal ground to jack point dimensions.

• Tail Weight / Stand
  Range: 17.5 - 39.5+ inches
  Weight: 375#+
  Applications: Determined by aircraft manufacturer specifications and maintenance manuals or reference data.

Our tail weight/stand is yet another dual-purpose unit offered by KHWMI.  As the name implies, the T W/S serves equally well as a tail Weight AND as a tail Stand.

Sold in kit form, the finished weight of the unit is typically no less than 375 pounds.  The unit is constructed to capably manage greater weight than the advertised weight.  However, the final weight of the unit is at the discretion of those completing the kit.  Nonetheless, the four heavy-duty rubber encased cast iron wheels allow easy movement and placement of the unit on any hard surface.  Further, the rubber encased wheels don't chip or ruin painted hangar floors, something inevitable with a solid cast iron wheel.

If you need a tail weight, a tail stand or both, we encourage you to make the most reasonable, economical and professional choice - a KHWMI Tail Weight/Stand.
