Description

HYVA Telescopic 1 Boom HA33 Spare Parts Catalogue – Logbook Code 7880878.0

This HYVA Telescopic 1 Boom HA33 Spare Parts Catalogue is the illustrated parts reference published for the HA33 telescopic crane boom under logbook code 7880878.0, edition 10/2022. It has been produced to allow the research and ordering of spare parts and to check their mounting position, with the machine divided into functional groups so any component can be traced from its position number on the illustration to its variant code, quantity and description in the matching table.

• Recommended spare parts list

Read as a whole, this spare parts catalogue gives a technician a complete position-by-position map of the HA33 telescopic boom. Rather than describing repair procedures, it tells you exactly which component sits where on the machine, what it is called, how many are needed and which variant code to quote. That makes it the reference you work from when a slide shoe is worn, a hose has burst, a seal kit is needed, a proximity switch has failed, or a sequence valve has to be identified before a replacement is ordered.

How the Group Tables Work

Every table follows the same structure. The exploded illustration carries ballooned position numbers; the table to the side lists those numbers against the variant code, the required quantity and the description. Hardware entries are given with their thread size, strength class and standard – for example hex screws to UNI 5737 or UNI 5739, flat washers to UNI 6592, split lock washers, stopnuts and self-locking ringnuts. Where a component exists in more than one version, the table shows the variant code so the correct item is selected for the machine on the bench.

Several groups are date-stamped. Validity notes such as VALID UNTIL December 2010, VALID FROM January 2011, VALID FROM January 2013 and VALID FROM January 2022 appear beside the affected illustrations, so an earlier build and a later build of the same HA33 boom can be told apart before a part is ordered. The wireless control group on page 86 also carries serial number thresholds – valid from S/N 27611, from S/N 99888 and from S/N 200712 – which is exactly the kind of detail that prevents a wrong transmitter or receiver being supplied.

Hydraulic and Electrical Coverage

The hydraulic side of the catalogue covers the full telescopic chain: the stabiliser rams, the lifting hydraulic cylinder, and the first, second, third and fourth extension cylinders, each with its own breakdown of cylinder, rod unit, piston, close nipple, stopnut and seal kit. Pipework is covered in detail – straight pipe fittings in the 9/16-18, 3/4-16 and 7/8-14 families, 90 degree connections, tee fittings, banjo bolts, sealing washers, bonderized tubes, sequence valves, overcenter valves and hose burst valves – so a complete circuit can be rebuilt from the tables rather than guessed at.

The electrical and electronic side covers the load indication system, the moment limiting device, the electro-hydraulic control valve groups, proximity switch position sensors, microswitches, audible alarm lighting, the junction box, cable leads, solenoids in both 12 V and 24 V, the battery compartment and the wireless control kits. Control symbol plates are also listed, which is useful when a panel has faded or a symbol has worn off.

Mechanical Sections and Wear Parts

The extension and boom tables list the parts that actually wear: slide shoes, thickness plates, keep plates, buttons for the control board, bushings, self-lubricating bushings, spacers, self-locking ringnuts, pins and pin assemblies, cotter pins, swivel hooks, guide bushings and coupling backlash buttons. Each is tied to a position number on the corresponding extension illustration, so the correct shoe or plate is identified for the 1S, 2S, 3S or 4S mechanical extension rather than a generic equivalent.

The final section of the file is a consolidated recommended spare parts list, grouping the items most likely to be needed in service – seal kits, slide shoes, oil filter and filtering cartridge, pressure gauge, thermometer, proximity switches, microswitches, hose burst valve, O-ring joints, bushings, thrust bearing ring and centering ring – under a single reference so a stock order can be put together quickly.

What This HYVA HA33 Spare Parts Catalogue Lets You Do

With this catalogue open you can identify a component on the machine, confirm its correct position number, and quote the exact variant code when ordering – which is the difference between a part that fits and a return. It supports the jobs that come up most often on an HA33 telescopic boom: replacing slide shoes and wear plates on the extensions, rebuilding a leaking extension or lifting cylinder with the right seal kit, tracing a failed hose or fitting in the hydraulic circuit, replacing a proximity switch or microswitch in the moment limiting or load indication system, and sourcing the correct solenoid voltage for the control valve group.

Working from the illustrated group tables also means the mounting position is checked before anything is disturbed, so hardware goes back in the right place with the right quantity and the right standard of screw, washer and lock nut. For anyone maintaining, servicing or rebuilding this boom, that removes the guesswork that costs time on site.
