Norco 76399 100 Ton Hydraulic Bottle Jack, Air and Manual Operation
You're staring down a job that would flatten a standard bottle jack. A loaded semi axle, a piece of farm equipment that outweighs your truck, a construction load that needs serious clearance before anyone crawls underneath. That's exactly what the Norco 76399 is built for. This is a 100 ton hydraulic bottle jack that runs on air or manual power, so you're never stuck waiting on a compressor to get a lift started.
Most jacks force you to pick one method and live with it. The 76399 doesn't. Connect it to shop air and let the pump do the work, or switch to manual pumping when you're in a spot without an air line. Same jack, same 100 ton rating, whichever way you power it. That flexibility matters when you're working trucking yards, farm equipment, or construction sites where air access isn't guaranteed.
A pressure gauge is built right into the unit, so you can watch your load pressure instead of guessing at it. The ram is chrome plated, which keeps corrosion from creeping in and eating away at the seal surface over years of use. Front wheels and a fixed handle mean you're rolling this jack into position instead of dragging it, which matters more than it sounds like once you've moved a jack this size a few dozen times.
Norco has been building hydraulic jacks and lifting equipment for professionals for years, and that reputation is why shops keep buying their equipment instead of chasing cheaper imports. Buy the 76399 through Garage Supply Guys and you've got a direct line to support and documentation if you ever need to reference the manual again, no digging through a manufacturer site to find it.

Applications
Loaded semi axles and heavy trailers need a jack that won't buckle under the weight. The 76399 handles them without breaking a sweat.
Combines, tractors, and other farm machinery run heavy and often sit in fields far from an air compressor. Manual mode keeps you moving either way.
Heavy machinery on a job site doesn't wait for the right tool. Front wheels and a fixed handle mean you're rolling this into position fast.
Mining equipment brings some of the heaviest loads you'll ever lift. A 100 ton rating gives you the margin that operation demands.

Frequently Asked Questions
Can I run this jack without an air compressor?
Yes. The 76399 operates on air or manual power. If you don't have shop air available, you can pump it by hand and still get the full 100 ton capacity.
What's the lifting range on this jack?
It lifts from 11.8 inches at its lowest point to 17.7 inches at full extension, giving you 5.9 inches of stroke to work with.
What air pressure does it need to run?
The jack operates within a 100 to 130 PSI range. Check your shop air supply against that range before running it in air mode.
Is this jack heavy to move around the shop?
It ships at 190 lbs, so it's not something you'll carry by hand. That's why it comes with front wheels and a fixed handle, so you roll it into position instead of lifting it.
Will the ram hold up over years of use?
The ram is chrome plated, which protects against corrosion and pitting that would otherwise wear down the seal surface over time.
How do I know how much pressure I'm applying?
There's a built-in pressure gauge on the unit, so you can monitor your load pressure directly instead of estimating it.
Is 100 tons enough for a fully loaded semi axle?
Yes. A 100 ton capacity covers loaded semi axles, heavy trailers, and most heavy trucking equipment you'd encounter in a fleet shop.
Can this jack handle farm equipment like a combine?
Yes. At 100 tons of capacity, the 76399 is rated for heavy farm machinery, including combines and tractors, whether or not you have air access in the field.
What's the difference between the 76399 and Norco's other bottle jacks?
The 76399 is the 100 ton model with air and manual operation. Norco also offers the 76330 and 76333 at 30 tons and the 76350 at 50 tons, all standard manual operation.
Does GSG have documentation for this jack if I need to reference it later?
Yes. The user manual is available as a PDF in the Documents section above, so you can pull it up any time you need operating details.
