Technical Description & Manual Scope

Machine: Liebherr LGD 1550 Mobile Crane (Lattice Boom) Serial Number: 073713 Publication Number: BAL-No. 04919-02-02 Format: PDF (791 Pages)

OEM Operational Documentation Overview

This master operating manual provides definitive technical guidance for the Liebherr LGD 1550, a high-capacity lattice boom mobile crane. Unlike standard telescopic manuals, this document details the complex modularity of the lattice system, covering the integration of heavy-lift derrick attachments with an all-terrain chassis. It serves as the primary reference for configuration planning, assembly/disassembly procedures, and systems diagnostics.

1. Boom Configuration & Attachment Systems

The manual offers granular detail on the LGD 1550’s modular boom systems, including assembly protocols and rigging schematics for:

• SL-System: Heavy-lift main boom configurations.
• SW-System: Luffing fly jib combinations for extended reach and “up-and-over” capabilities.
• Derrick (D) System: Superlift/Derrick counterweight attachments (floating and tray ballast) for max load moment enhancement.
• Hybrid Configurations: Comprehensive setup data for specialized modes including SDWB (Suspended Derrick / Luffing Jib), SDB, SLN, and SDBWN.
• Component Rigging: Detailed instructions for the 100t boom nose, A-bracket erection, and sliding arm installation.

2. Operational Logistics & Load Charts

Critical engineering data for lift planning and on-site stability:

• Raising & Lowering Charts: Specific kinetic limits for erecting long boom combinations to prevent structural failure during setup.
• Reeving Plans: Complete rope reeving diagrams for various hook blocks and hoist configurations, ensuring correct line pull distribution.
• Ballast Logistics: Assembly/disassembly sequences for base plates and counterweight slabs, including stacking logic for various load curves.

3. Chassis & Powertrain Logic

Technical operation of the carrier unit:

• Axle & Suspension: Operation of the hydropneumatic suspension, including level control and specific axle locking protocols for static stability.
• Steering & Braking: Pneumatic brake system inspection, retarder operation, and multi-mode steering configurations for tight job site maneuvering.
• Drive Train: Gearbox management and differential lock engagement strategies for off-road terrain.

4. LICCON Computer System & Diagnostics

A dedicated section covers the Liebherr Computed Control (LICCON) system, the brain of the crane:

• LMI Setup: Programming the Load Moment Indicator for specific boom codes and counterweight charts.
• Error Localization: Diagnostic codes and troubleshooting flowcharts to isolate electrical or sensor faults within the safety system.
• Safety Cut-offs: Parameters for hoist limit switches, wind speed monitoring, and ground pressure sensors.

5. Maintenance & Service Standards

Factory-mandated intervals and procedures to maintain operational certification:

• Lubrication Schedules: Complete charts for greasing boom pivot points, slew rings, and wire ropes.
• Wire Rope Inspection: ISO-standard “Discard Criteria” for hoisting and luffing ropes.
• Hydraulics & Pneumatics: Pressure monitoring for accumulator cylinders and tension columns.
