Hyva HV77 Articulated Boom Spare Parts Catalogue 7845513.0 – PDF Parts Manual

Description

Hyva HV77 Articulated Boom Spare Parts Catalogue 7845513.0

This is the illustrated spare parts catalogue for the Hyva HV77 articulated boom, published under logbook code 7845513.0, Edition 02/2023. It is a parts-identification document: every assembly on the boom is broken down into an exploded drawing with a matching position table, so a part can be looked up by where it sits on the machine rather than by guessing a description. The catalogue covers the whole articulated boom assembly, from the mounting base and column through to the extensions, the CE control unit, the stabilizer legs and the hydraulic and electrical hardware that runs between them.

Anyone ordering parts for an HV77 will recognise the problem this solves: the same fastener, fitting or seal appears in several places on the boom, and a parts list without the drawing is guesswork. Here the exploded view and the row-by-row table sit on the same page, so variant codes, quantities and the exact component designation are visible together.

Chapters Covered

The catalogue is organised as a numbered series of table pages, each headed with its own table code. The main groups are:

• Base
• Column
• Oil tank / Oil tank (LI – LIG)
• Oil filter
• Hydraulic system (Lifting hydraulic cylinder) and Lifting hydraulic cylinder
• 1st Boom
• Hydraulic system (Articulation Hydraulic jack) and Articulation hydraulic jack
• 2nd Boom
• 1st Extension and 1st Extension hydraulic
• 2nd Extension
• 3rd Extension
• 1st, 2nd and 3rd Activation for 1S / 2S / 3S
• Additional Actuation
• Manual Extension (1S / 2S / 3S versions)
• Hook Kit
• Load Indication System (LIS/RLC)
• Actuation for Winch / Support for Winch’s pulley kit
• Pump Hand Kit (manual controls)
• Attachment for Basket
• Hydraulic system (stabilizers) and Stabilizer Hydraulic jack
• Control unit (CE)
• Control valve variants and extra function kits (closed centre / open centre spool, EN12999-A3)
• Plate kit (Generic Gru) and instruction labels
• Slewing cylinder and rotation limiting device
• Electrical wiring and microswitch assemblies

What that structure gives a technician is direct access to the part rather than to a repair procedure. Each page pairs a component-level drawing with a table listing position number, variant code, quantity and description — for example hex screws with their thread size and standard, flat and split lock washers, grease nipples, straight pipe fittings, 90° connections, rotary unions, flexible hoses, bonderized tubes, valves, seal kits, slide shoes, buttons, bushings, snap rings, forks and fork clips, control levers, knobs and collars. Because the catalogue keeps revision notes such as “VALID FROM December 2010”, “VALID FROM June 2011”, “VALID FROM November 2013”, “VALID FROM June 2020” and “valid only for S/N 29395 – 29396”, the tables let you match a part to the build period of the machine rather than to a single generic specification.

What This Catalogue Covers On The Machine

Boom structure and extensions

The 1st Boom, 2nd Boom, 1st Extension, 2nd Extension and 3rd Extension each have their own exploded page, showing the bushings, self-locking ringnuts, eye bolts, collars, hose clamps, slide shoes, thickness plates and backlash inserts that make up the sliding and pivoting interfaces. These are the pages you want when the boom sections develop play or when a slide shoe needs replacing.

Hydraulics

The lifting cylinder, articulation jack and each extension cylinder are catalogued separately, with their rods, pistons, seals, O-rings, anti-extrusion rings, W-rings, close nipples and seal kits listed individually. Hose runs between the base and the boom sections are shown with their fittings — straight pipe fittings, 90° connections, tapping points, tee fittings, rotary unions, reducing fittings, female plugs, sealing washers, throttle screws and non-return valves. Stabilizer legs and their hydraulic jacks have dedicated tables, and the slewing cylinder page includes the toothed rack, sliding block and seal kit.

Control and electrical

The Control unit (CE) pages detail the control levers, handles, forks and fork clips, grease nipples, cable leads and the mounting hardware of the valve block. Separate pages cover the control valve in its 12V and 24V solenoid variants, the max pressure valve, contact terminals, casings and protective boots, plus the extra function kits for closed centre and open centre spools and the EN12999-A3 versions. Wiring pages cover the electric wiring assembly, lighting with audible alarm, microswitch wire assemblies, proximity switches and the connectors used on the boom.

Lifting and load equipment

The swivel hook, hook kit, load indication system (LIS/RLC) with shackles, electric cable and battery, the winch support and winch pulley support, and the hand pump kit for manual controls all have their own tables. A dedicated page covers the plate kit and instruction/stabilizer labels.

Why A Parts Catalogue Beats Guessing

Ordering the wrong fitting on a hydraulic boom is expensive in both directions — a part that doesn’t fit, and a machine standing idle while the correct one is sourced. The value of this catalogue is that the description column carries the actual specification of each item, so a straight pipe fitting is listed with its thread and standard, a washer with its diameter and standard, a screw with its thread, grade and UNI number, and a seal with its size class. Matching that against the failed component, and against the drawing to confirm location and quantity, removes most of the risk from the order.

It is equally useful for planning: seeing that a seal kit exists for a cylinder, or that a slide shoe and button are catalogued separately, tells you what a rebuild will actually consume before the boom is stripped down.
