Just got off teh phone with a maintenance supervisor who needed something stable enough for a 737 main gear lift, and this is exactly where these tripod jacks fit in — he was tired of wobbling stands that didn't inspire confidence during a tire swap.
We've got ZATJ50 and ZATJ90 models covering that 50 to 90-ton range, with stroke somewhere between 242 and 270mm depending on which one you pick, and there's a screw rod extension of about 85-90mm built into each unit for that fine height adjustment after the hydraulics do the heavy lifting.
Basically you're getting a manual pump setup with overload protection, which is what you'd expect for fuselage or wing lifts on heavy aircraft, but it's not really suited for quick repeated cycles — 2-3 lifts per job is fine, but 15 lifts in a shift will wear your arm out. The minimum height runs 256-270mm and max height hits 630mm, give or take, so it's best for larger airframes where you've got enough clearance to roll it under.
Custom trim colors or base sizes? We can do that, usually in about 20 days or so form order confirmation. Minimum quantiy is one unit, but we usually stock the 50-ton and 60-ton versions ready to ship within a week — the 90 may need lead time confirmation.
The ZATJ50 has a minimum height of 256mm. That’s the lowest the jack can go when fully retracted, so make sure your aircraft’s clearance allows for it.
Yes, each unit comes with a certificate of compliance and can include load test reports if you need them. Just let us know what your quality team requires.
Typically 30-45 days for a standard order of that size, but we can speed it up if you’re in a rush. Customization might add a week or two.
Yes, customization is available. We can adjust the cylinder stroke or screw rod extension within reasonable limits—just share your specs, and we’ll quote you.
Keep it in a dry, clean area, preferably with the cylinder retracted and the safety lock engaged. Avoid leaving it exposed to moisture to prevent rust on the steel parts.
