2004 - Liebherr LTM1400-1 AT-2 All Terrain Crane

About this machine

This Liebherr LTM1400-1 AT-2 is an all terrain crane — sometimes referred to as an all terrain mobile crane — a heavy lifting machine designed to travel under its own power on public roads and then set up and operate across a wide range of ground conditions, from prepared construction sites to rough or uneven terrain. Liebherr is a globally recognised manufacturer of construction and heavy lifting equipment, with its crane division regarded as one of the leading producers of mobile, crawler, and tower cranes serving construction, energy, petrochemical, and infrastructure industries worldwide. This example, manufactured in 2004, is offered in used condition and is currently located in South Korea.

The crane delivers a rated load capacity of 400,000 kg, with a maximum tip capacity of 1.5 tonnes at its furthest working radius. The main boom reaches a height of 60 metres, which extends to a maximum lifting height of 130 metres when the luffing jib system is deployed. The maximum boom radius is 100 metres, and the luffing jib itself extends to 84 metres at its maximum configuration. These dimensions reflect a machine suited to high-reach, large-radius lift programmes of considerable complexity.

Hook travel speed ranges from 0 to 170 metres per minute, allowing the operator to manage precision lifts at low speed or move loads quickly when working conditions permit. The full ballast counterweight is specified at 140,000 kg, which is the configuration required to achieve the crane's maximum rated lifting performance. The machine travels at up to 80 km/h on public roads, making repositioning between sites practical without the need for low-loader transport of the entire carrier unit.

The carrier is powered by a Liebherr D 9508 A7 engine, while the superstructure runs a separate Liebherr D 936 L A6 engine — a dual-engine arrangement typical of cranes of this class, allowing the superstructure to operate independently of the carrier. The carrier engine is a V-configuration, eight-cylinder, four-valves-per-cylinder diesel unit displacing 16,162 cc and producing 450 kW (612 hp). Both engines meet Euro 3 / EPA Tier 3 emissions standards.

The carrier rides on seven axles in a 14x8x14 configuration, providing fourteen driven wheels and fourteen steered wheels as standard, which underpins its all terrain capability. Suspension is hydropneumatic, described by Liebherr as Niveaumatik, a system that maintains a level chassis across uneven ground and assists with axle load distribution. The travel weight with a 12-tonne-per-axle load distribution is 84,000 kg, with total transport dimensions of 18,450 mm in length, 3,000 mm in width, and 4,000 mm in height. Net weight varies depending on transport configuration.
