HIAB BZ 20-152 (S) 2009 Parts Catalog – Factory OEM Specs for Crane Hydraulics

You’re wrenching on a BZ 20-152 (S). Maybe the tilt cylinder is weeping, or the valve bank’s got a dead solenoid. First thing: don’t reach for a generic O-ring assortment. This is a HIAB crane, and that means the hydraulic system runs at 170 bar. The wrong seal can blow out and cost you a lot more than the right part would have. The HIAB BZ 20-152 (S) 2009 Parts Catalog is the only way to get the correct part numbers without playing parts roulette. 94 pages of exploded views and factory part numbers, broken down by chassis serial number. No aftermarket guesswork.

Cylinders: Lift and Tilt Separated by Serial Number

Chapter 3 in this catalog cuts straight to the cylinders. The lift cylinder (part 61263) is on page 18. The tilt cylinder S (67269) is on page 20. You’ll see the exploded view with every washer and seal individually numbered. If the tilt cylinder is the ‘S’ variant, the seal kit is different. Don’t swap them. Check the serial number on the crane tag — the catalog uses SN breaks for the liftchassis in Chapter 1, but the cylinder parts are the same across the run. That said, the tilt cylinder S is specific to the 152 (S) model. Order the wrong one and you’re losing a day waiting on the right part.

Hydraulic Unit Variants: 12V vs 24V at 170 Bar

Chapter 5 splits the hydraulic units by voltage and serial number range. You’ve got the early 379 units (page 26 for 24 volt, page 28 for 12 volt) up to SN 75337. Then the 6400 units start at SN 106079. Page 38 shows the 6400 12 volt unit, page 40 the 24 volt. There’s also a pressure guard series starting at SN 106079 on pages 42-44. Every single part number changes when the voltage or the serial number shifts. I’ve seen guys order a 12-volt pump for a 24-volt machine because they didn’t check. Then the system won’t build pressure. You don’t have time for that.

Valve Systems: 12 and 24 Volt Across Three Serial Ranges

Chapter 5.9 covers the valve systems. Three distinct serial number breaks: SN 1060-, SN 1795-, and SN 2062-. Each has its own exploded diagram and part numbers for the valve bank solenoids, cartridges, and coil assemblies. The 12-volt system is 32209 series; 24 volt is 32210. Page 62 for the early 12-volt, page 64 for 24. If you mis-diagnose a solenoid as failed but actually swapped coils from the wrong voltage range, you’ll smoke the coil. This catalog gives you the exact coil part number based on your crane’s build date.

Safety Valve Selection by Serial Number Range

Chapter 6.1.1 through 6.1.4 are all about the safety valves. Part 67185 for 24 volt, 67184 for 12 volt. But the sub-variants (a, b, c) change at SN 106074, SN 123713, and SN 139047. Pages 76 to 90. The safety valve is the last line of defense against an over-center load. Install the wrong cracking pressure and the crane could drop a load. Don’t guess. Look at the SN on your crane’s data plate, match it to the table on page 3 of the catalog, then flip to the right page.

Liftchassis and Platform Options – Steel vs Aluminum

Chapter 1 shows the liftchassis assembly (C8A0227 and C8A0227a) for two SN ranges. Chapter 2 lists five platform variants: steel platform (PLA0405) and four aluminum platforms (PLA0406, 0407, 0417, 0418). Pages 8 through 16. If you’re replacing a platform, the bolt pattern and mounting brackets differ between steel and aluminum. The catalog includes the fastener part numbers and torque specs (though for torque data you’d want the repair manual, not this parts book). Still, having the correct bolts means you avoid snapping a head off in an aluminum casting.

What Parts Does This Catalog Cover – And What It Doesn’t

This is a Parts Catalog, not a service manual. It gives you part numbers, exploded diagrams, and quantities. What it does not give you: repair procedures, torque values, or troubleshooting. You’ll still need the OEM service manual for assembly and adjustment specs. For context on crane hydraulic safety standards, see the Automotive Industry Overview [LINK_ID_EXT_0]. And for general hydraulic system basics, the Automotive Industry Overview [LINK_ID_EXT_1] covers fluid power fundamentals, but for your specific crane, this catalog is the only source you should trust.

If you work on other HIAB models, here are related factory catalogs: HIAB ZL 250-135 2009 Parts Catalog – Factory OEM Manual, HIAB 175 ZA 150 2009 Parts Catalog – OEM Factory Specs, and HIAB ZA 200, 175 2009 Parts Catalog – Factory OEM.

Does this catalog include repair procedures or torque specs?

No, it’s a parts identification catalog only. You need the separate service manual for disassembly and torque values.

How do I find the correct hydraulic unit for my crane’s serial number?

The catalog organizes hydraulic units in Chapter 5 by serial number range. First locate your crane’s serial number (stamped on the liftchassis plate). Then reference the table on page 3 to see which SN range your unit falls into. For example, if your SN is between 75338 and 106078, turn to page 34 for the 12-volt unit or page 36 for 24-volt. Each page shows the complete part list with O-ring sizes, motor part numbers, and pressure relief cartridge IDs. Matching the wrong unit to your voltage or SN means ordering parts that won’t physically fit or will operate at incorrect pressure. The few minutes spent cross-referencing will save you the cost of a return shipment and downtime.
