The new TRITASK Aircraft Jacks with their powder-coated Inner Slide Tubes form the “anchor” of the new TriTask System. The top of the A600 and A700 Series Inner Slide Tubes are designed to receive an AT-JPRn, AT-EBnnn or a top-of-the-jack aircraft weighing Load Cell.

The Inner Slide Tubes for the A500 Series have a built-in 1.25″ (32mm) round Jacking Point receiving socket machined into the top of its protruding anchoring stud.The AT500-CA Conversion Adapter can be mounted on the anchoring stud, which will then allow the A500 Series Inner Slide Tubes to function the same as the A600 and A700 Series Inner Slide Tubes.

Each Meyer Hydraulics Aircraft Jack comes with the Standard Inner Slide Tube (see the Stat Chart for each TriTask Jack Series). We have also designed EXTENDED Inner Slide Tubes for the A622 (AT62234) and the A634 (AT63448) TriTask Jacks. 

By removing the Standard Inner Slide Tube and replacing it with the Extended Tube, the user increases the base “low” jacking point of the unit.  This can be a very cost-effective way to make the A622 or A634 TriTask Jack even more versatile. 

For the older discontinued A422, A427, A434, A-5 and A-6 Aircraft Jacks, replacement Standard Inner Slide Tubes are available. The following EXTENDED Inner Slide Tube options are also available for increasing the lifting range of these jack models: AT42228 and AT42234 (for A422 and A-5), AT43454 (for A434 and A-6). The addition of the ATC-4 or ATC-8 which may be used along with these Extended Inner Slide Tubes for even greater range.

Made of solid steel and powder-coated with a long-lasting yellow finish for easy spotting, these JPR Receivers have been designed to be put into the top of an A600 or A700 Series Aircraft Jack’s Inner Slide Tube, an AT-EBnnn Extension Bar or the AT500-CA Conversion Adapter for the A500 Series. The AT-JPR1 is a 1.5″ x .187″ (38x5mm) pad with a .875″ (22mm) round Jacking Point receiving socket. The AT-JPR2 is a little larger with a 1.75″ x .375″ (44x10mm) pad with a 1.25″ (32mm) round receiving socket. Both have a 1″ x 1″ (25.25mm) round stem.

This optional 2.25″ (57mm) round steel powder-coated Adapter only connects to the A500 Series Inner Slide Tubes and adds .875″ (22mm) to the height of the Jack. After securing the Adapter to the Inner Slide Tube’s protruding anchoring stud, an AT-JPRn, AT-EBnnn or a top-of-the-jack aircraft weighing Load Cell can be quickly put into the top of the Conversion Adapter.

Use the AT500-STA for the following older models with treaded slide tube tops.

• A419-All
• A421-All
• A519 serial numbers 0 through 1062
• A521 serial numbers 0 through 1068

Twelve (12) optional 1.75″ (44mm) solid steel powder-coated Extension Bars of various lengths screw into the top of an A600 or A700 Aircraft Jack’s Inner Slide Tube or into the AT500-CA Conversion Adapter used on the A500 Series. They extend the height of the Jack 1.5″ to 12.5″ (38 to 318mm) in 1″ (25mm) increments. Both of the AT-JPRn Jacking Point Receivers or a top-of-the-jack aircraft weighing Load Cell can quickly be put into the top non-threaded hole of an AT-EBnnn Extension Bar. The AT-EBnnn’s cannot be used on the A755C and A760A Aircraft Jacks.

A Load Cell with the standard 1″ x 1″ (25x25mm) round stem can be quickly put into the top of an A600 or A700 Series Aircraft Jack’s Inner Slide Tube, an AT-EBnnn Extension Bar or the top of an AT500-CA Conversion Adapter used on the A500 Series.

Meyer Hydraulics does not make or distribute aircraft weighing Load Cells or Scales. These are readily available from other sources, such as one of our Select Distributors or Jackson Aircraft Weighing Scales.
