Crane and Boom Configuration Coverage

The manual defines the principal boom systems used with the LTM 1400-7.1. The telescopic boom is identified as T, while TY describes the telescopic boom with Y stay ropes. Fixed lattice jib arrangements include TF and TYSF configurations, and luffing lattice jib arrangements include TN and TYSN. The telescopic boom itself uses one articulated piece and four telescopic sections, with a stated boom length of 15.40 m to 60 m.

For additional reach configurations, the document covers fixed lattice jib equipment from 7.00 m to 56.00 m and luffing lattice jib equipment from 14.00 m to 84.00 m. Illustrated boom-combination pages show the relationships among telescopic boom length, lattice sections, guying and adapters, helping operators and assembly personnel identify the equipment arrangement addressed by the operating procedures.

Machine Systems and Technical Reference

The LTM 1400-7.1 chassis section describes a seven-axle carrier with hydraulic supports, hydro-pneumatic axle suspension and steering across all axles. The chassis engine is identified as the Liebherr D 9508 A7, an 8-cylinder water-cooled diesel rated at 450 kW at 1900 rpm with maximum torque of 2840 Nm at 1100 to 1500 rpm. The transmission is a ZF TC-TRONIC HD automatic system with 12 forward gears and 2 reverse gears.

The crane superstructure uses a Liebherr D 936L A6 6-cylinder water-cooled diesel rated at 240 kW at 1800 rpm, with maximum torque of 1525 Nm at 1500 rpm. Crane movements are driven through a diesel-hydraulic system, and the manual describes hoisting, luffing, slewing, telescoping and lattice-jib adjustment functions. The safety equipment description includes the LICCON overload system, hoist limit switch and safety valves used to protect the hydraulic system against pipe or hose failure.

Technical data sections provide information for dimensions, tires, weights, support forces, driving and crane speeds, rope diameters and lifting heights. Among the stated data are a 10 m by 9.5 m support basis, total ballast of 100 t, maximum support forces of 1240 kN at the front and 1760 kN at the rear, and road driving speeds reaching 80 km/h in the listed tire configurations. Hoist gears I and II are specified from 0 to 130 m/min for a single strand, hoist gear III from 0 to 150 m/min, and the slewing gear from 0 to 1.5 rpm. The technical section also includes illustrated lifting-height diagrams for T, TY, TF, TYSF, TN and TYSN boom arrangements.

LICCON Controls and Crane Operation

A major portion of this Liebherr LTM 1400-7.1 operating instructions manual is devoted to the controls used on the chassis and crane superstructure. Chassis coverage includes driver controls, display and warning functions, axle suspension, steering programs, differential locks, support control units and preparation before travel. The travel chapters then address crane driving conditions, starting and stopping the engine, driving, steering and job-site positioning.

The superstructure section explains the LICCON computer system and its operating programs. Coverage includes system boot-up, operating mode preselection, control elements, the Set up program, Operation program, Telescoping program, Control parameter program, Working range limitation program, Support program, Engine monitoring program and Tele guying program. Separate chapters address crane start-up, safety equipment and the main crane movements of luffing, lifting and lowering, turning and telescoping.

Equipment Assembly, Reeving and Load Handling

The manual goes beyond normal cab operation and provides extensive equipment procedures. Rope reeving coverage includes wire ropes and rope end connections, assembly-winch procedures, hook-block reeving, hoist-limit-switch weight installation, wedge-lock assembly and reeving arrangements. Counterweight sections provide assembly, telescoping and disassembly procedures, while the working-with-a-load chapter addresses checks before work, telescoping with a load, taking on a load and crane operation.

Two-hook operation is also covered with the relevant boom and jib arrangements. Equipment chapters provide assembly, erection, operation, take-down and disassembly information for fixed lattice jib TF, luffing lattice jib TN, guyed telescopic boom TY, guyed luffing lattice jib and guyed fixed lattice jib. Further procedures cover Winch 3, telescopic boom removal and installation, luffing cylinder arrangements, sliding beams, sliding beam boxes, hook blocks and the N head piece. Erection and take-down charts are included for T, TY, TF, TYSF, TN and TYSN operation.

Safety and Job-Site Preparation

Safety information is integrated throughout the document and also occupies a substantial dedicated section. Topics include traffic regulations, first commissioning, job planning, general safety guidelines, ladder use, crane signs, antifall protection and safe access to the crane. Job-planning guidance addresses the load, required hoisting height, boom projection, ground bearing capacity, available assembly space, weather conditions and the equipment needed for the planned crane application.

The manual discusses support setup, crane alignment, ground pressure, work near slopes and excavations, electrical transmission lines, wind effects, grounding, work near transmitters and coordination when multiple cranes are involved. Hand signals for lifting, lowering, slewing, boom movement and winch selection are illustrated. Additional safety coverage includes working with suspended loads, exceptional personnel-lifting situations, thunderstorms, external electrical power and procedures for interrupting or ending crane operation.

Its inspection chapters extend that coverage to structural components, telescopic-boom locking and rope-feed systems, overload protection, winches, wire ropes, load hooks, hydraulic hoses, pneumatic brakes, guy rods and ladders.

Service, Maintenance and Inspection Reference

The later sections make the Liebherr LTM 1400-7.1 Mobile Crane Operating Instructions Manual – PDF useful beyond day-to-day operating controls. Maintenance schedules are provided separately for the crane chassis, crane superstructure and crane boom. Maintenance guidance covers the chassis diesel engine, automatic transmission with torque converter coupling, distributor gear, hydraulic system, compressed-air and brake system, steering, tires, axles and electrical system. Superstructure maintenance includes the crane engine, pump distributor gear, hydraulic system, central lubrication system, slewing ring connection, winches, hoist and control ropes, guy winches, slewing gear and hydraulic hose lines.

The manual also contains fill-quantity and lubrication information, specified service fluids and lubricants, plus a problem-response section with error diagnostics and measures for defective components. Dedicated inspection chapters explain recurring checks for load-bearing crane structures, telescopic-boom mechanisms, safety ropes and anchor points, overload protection, winches, crane wire ropes, hooks, hydraulic hose lines and other safety-relevant components.
