The Liebherr LTM 1120-4.1 Driving with Equipment in Place Operating Instructions – BAL 228411-01-02 is a focused document for crane operators and site teams who need to travel the LTM 1120-4.1 with lattice jibs, telescopic boom sections, or other equipment still mounted. It brings together the preparatory steps, safety conditions, steering limits, axle-load monitoring, gradient restrictions, and the setup-specific charts that govern this type of travel. Instead of relying on general crane knowledge, this manual gives you the machine-specific values and procedures required before moving the crane on its blocked axles.

What This Manual Helps You Do

Use these Liebherr LTM 1120-4.1 driving with equipment in place instructions to prepare the carrier for travel, verify the crane superstructure is mechanically locked, telescope and luff the boom to the correct positions, lower the crane onto blocked axles, and confirm axle pressures before moving. The document also explains permissible steering programs for axle loads above 12 t, how to judge uphill and downhill gradients, and when a guide is needed to watch the luffed boom and supports. For anyone responsible for a loaded travel configuration, the chapter 15.05 charts are central: they match counterweight radius, boom direction, lattice jib type, hook block, boom angle, support width, maximum axle load, and maximum wind speed to the actual machine setup.

Beyond the travel procedure itself, this LTM 1120-4.1 operating instructions PDF includes the safety and warning framework that applies to the crane. It covers intended use, non-destined use, ambient temperature limits, safety equipment checks, original equipment and spare parts requirements, and directional definitions for mobile cranes. That context matters because driving with equipment in place is only permitted when the crane is in the correct configuration and when the conditions in the charts are observed. The manual also includes conversion tables and optional equipment notes, so the operator can work with the same units and terminology used in the load charts and machine displays.

Why This Information Matters

Driving a mobile crane with equipment in place is a high-risk operation. The Liebherr LTM 1120-4.1 manual repeatedly warns that the crane can topple if the specified conditions, notes, and values are not followed. The axle pressure indicators, blocked axle suspension, support width, boom angle, and counterweight radius all interact. Using the wrong chart or exceeding a permissible gradient can overload axles or tires, damage the steering system, or create an unstable travel condition. This document gives you the exact prerequisites: level ground, correct tire pressure, pinned sliding beams, support cylinders about 50 mm above the ground, no counterweight on the crane chassis, and a mechanically locked superstructure.

The steering program section is especially practical for LTM 1120-4.1 travel with more than 12 t axle load. It identifies permissible steering programs and warns against using reduced sheer out dimension or independent steering under those loads. The uphill and downhill gradient section sets maximum values and lateral tilt limits, while the axle pressure section explains when to realign the crane or relieve tire load. Together, these instructions support safer decision-making before the crane moves, not after a problem appears.
