Liebherr HS 855 HD Crawler Crane Technical Information Manual – PDF

Description

Liebherr HS 855 HD Technical Information Manual

This is the Liebherr HS 855 HD technical information manual, issued for machine serial number 184 664, version 001. It is the technical volume of the HS 855 HD documentation set produced by Liebherr-Werk Nenzing GmbH and it sits alongside the operating manual, load chart book and spare parts catalogue. Where those volumes tell an operator how to run the crane and a storeman which part to order, this one shows how the machine is actually put together and how its systems are wired and plumbed.

The Liebherr HS 855 HD technical information manual is built around large-format engineering drawings and schematics rather than pages of prose. General arrangement drawings show the complete machine and the attachment point transport device; hydraulic schematics break the uppercarriage and undercarriage circuits down valve by valve; electrical charts map the basic machine, cabin, electrical box, boom foot and boom head, printed circuit P1 and central power unit. The options section adds refuelling system, air conditioning, winch synchronisation, automatic central lubrication and emergency operation control.

Hydraulic and Winch Data Inside the HS 855 HD Technical Manual

The hydraulic section carries the winch parameter table for the HS 855 with the 450 kN layer, listing drum diameters of 558 mm, 630 mm and 750 mm, hydraulic motor types H6VM 160 and H6VM 200, pump types R4VG 140 with 350 l/min flow capacity, 305 to 335 bar working pressure, pressure control and pressure regulator values, and the resulting rope pull, rope speed and rope tension figures for each winding configuration. Maximum rope pull is given as 400 kN in the top rows and 280 kN in the lower rows, with hook speeds of 78, 102 and 124 m/min depending on configuration. Being able to read these figures against the schematic means a technician can verify pump output, relief settings and motor displacement on the actual machine instead of working from memory.

Electrical Charts for the HS 855 HD

The electrical chart set is unusually complete for a machine of this class. It includes the master control system layout with CAN1 through CAN4 buses, the central power unit wiring with fuses F1 through F8 and relays K1 through K23, the control desk and control panel connections, foot pedal and console wiring, screen wiper and screen washer circuits, radio, lighting, sensor inputs and outputs, and the module identification pages that map the digital and analogue input and output modules. The system uses a master controller with separate digital input, analogue input, digital output, analogue output and counter modules.

General Drawings and Transport Data

The general drawings chapter shows the HS 855 HD in its various boom and attachment configurations, and includes the transport weight table for the HS855: F1 at 100 t, F2 at 51.7 t, SP-X at 50.4 t, SP-Z at 1340 and total transport weight at 1656. The attachment point transport device drawing is included with its identification number, and the rigging notes give the minimum rope length, shackle ratings of 350 kN, and the centre-of-gravity reference point used when planning a lift or a road move.

Why the Liebherr HS 855 HD Technical Information Manual Matters

A crawler crane of this size cannot be maintained on guesswork. Relief valve settings, pump displacements, motor types, drum diameters, fuse ratings, relay designations and CAN bus assignments all have to be right, and every one of them is defined in this document. When a hydraulic function drifts, a fuse blows repeatedly or a control module drops off the bus, the schematic is what turns a vague symptom into a specific circuit to test.

The Liebherr HS 855 HD technical information manual gives the technician the drawing numbers, terminal designations, plug and socket references, component identifiers and hydraulic values needed to work methodically. It is the reference that sits behind every fault-finding session, every hydraulic adjustment and every electrical repair on this machine.
