Strato-lift TRX-13 Parts Catalog

I’ve seen more lift cylinders lock up from someone stuffing the wrong seal in than from actual wear. When you’re ordering parts for a Strato-lift TRX-13 Parts Catalog job – especially under a machine that’s holding a couple tons – you don’t get to guess. One wrong fitting or a misidentified brake cylinder means downtime, maybe a safety incident. This 64-page OEM parts catalog is the only source I trust for part numbers, hydraulic routing, and cylinder breakdowns. No aftermarket reprints, no scanned copies that blur the indexes. This is the factory document.

What’s Inside: 5 Sections, 64 Pages of Factory Data

Section 1 opens with the hydraulic diagram – Figure 1-A shows the exact hose routing, fitting sizes, and part numbers for every line from the pump to the lift cylinder. Page 3 starts that section. If you’re replacing a hose on the TRX-13, you look up the part number there, not in some third-party cross-reference that lists the wrong thread pitch. Section 2 dives into drive chassis components: steering axle, drive axle, brake components, battery box, ground control panel, and the power unit manifold. That’s where you’ll find Figure 2-K (Brake Cylinder) and Figure 2-J (Steering Cylinder) – both with exploded views and OEM part numbers. The brake assembly alone has a dozen different seals and spring sets. You need the right one for your serial number range. This catalog gives it.

Brake Cylinder and Brake Components: Exact Factory Specs

The TRX-13 uses a spring-applied, hydraulically released brake system. If the brake cylinder fails, the machine locks up – or worse, rolls. Figure 2-D in Section 2 covers every piece of the brake assembly: the cylinder itself, the friction disc, the hub, the return springs. Part numbers are listed with descriptions and quantities. No “refer to dealer” nonsense. You get the brake cylinder part number, you order it, you’re back running. Same for the cushion cylinder (Figure 2-L) – that’s the shock absorber for the boom travel. Missing that part can crack the frame. I’ve seen it.

Boom and Platform: Lift Cylinder, Lower Boom Arm, Platform Box

Section 3 covers boom components – Figure 3-B is the lift cylinder, Figure 3-A is the boom section itself. The lift cylinder on the TRX-13 uses a specific gland nut and seal kit. Without the factory diagram, you’ll likely order the wrong wiper seal. Section 4 is the platform: Figure 4-A the main platform, Figure 4-B the rear deck extension, Figure 4-C the platform control box. Want to know which toggle switch goes where? The control box diagram lists every switch, potentiometer, and connector part number. Section 5 is decals and placards – Figure 5-A shows exact placement for safety labels. OSHA cares about that. So should you.

3 Reasons You Want OEM Documentation, Not Aftermarket Copies

First, aftermarket reprints often omit the revision notes. The TRX-13 had serial number breaks – for example, the hydraulic diagram on page 4 includes a note “FROM SERIAL NUMBER 006300 a.O.M.” That means fittings changed after that serial. A generic copy might leave that note out. Second, aftermarket catalogs sometimes substitute “generic” part numbers that don’t cross correctly. I’ve had a customer order a “compatible” steering cylinder seal that was 2mm too thin. Leaked within a week. Third, the OEM catalog has the original Parker fitting designations (see note on Figure 1-A: “All fitting designations are from Parker”). That matters when you’re matching JIC vs. SAE vs. ORFS. You lose that with a third-party scan.

Does This Manual Cover the Fuel System or Engine?

This is a parts catalog for the aerial lift structure – hydraulics, chassis, boom, platform, decals. It does not cover the engine or fuel system of the carrier vehicle (e.g., a Ford or GM chassis). If you need the powertrain side, look for a service manual for the specific chassis. But everything that makes the TRX-13 lift and steer is in these 64 pages.

Get the Right Part the First Time

Before you start disassembling that brake cylinder or ordering a new lift cylinder, grab this catalog. Cross‑check the part number in the exploded view against what you have. Measure the hose length against the diagram. Then order. It saves you shipping time and the headache of a second teardown.

Q: Can I use this catalog to order parts for a TRX-13 built in 2020?

Yes, but verify the serial number. This catalog includes updates up to serial number 008300 and beyond. The hydraulic diagram from page 4 notes changes starting at 006300. If your machine is outside that range, contact Strato‑lift for a supplement.

Q: How do I find the steering cylinder part number?

Look in Section 2, Figure 2-J.
