Liebherr has unveiled the LTM 1230-5.1, the successor to the LTM 1200-5.1. In its development work, Liebherr pursued the objective of increasing the boom length and lifting capacity of its predecessor. The maximum hook height of the LTM 1230-5.1 has been increased by 10m to 111m.

Liebherr has a wide and variable range of lattice jibs for the new LTM 1230-5.1. The 11.5 to 22m folding jib can be mounted at an angle of 0°, 20° or 40°. The folding jib can be supplied with a hydraulic adjustment system as an option which allows it to luff with a full load between 0° and 40°. The pivot point for the folding jib can be raised using up to three straight 7 m lattice sections acting as telescopic boom extensions.

For the last three years, customers with the LTM 1250-5.1 have been able to install a long fixed jib to achieve a large radius, for example for hoisting over buildings. This lattice jib is also available for the new LTM 1230-5.1: a fixed jib up to 43m in length can be achieved with an additional TF adapter (connection between the telescopic boom and the fixed jib), a reducer section and a head piece. Existing lattice extensions are used for this purpose. This jib is generally hydraulically adjustable between 0° and 45° and can therefore be used like a luffing jib. The existing parts can be used to assemble a particularly powerful jib up to 39m in length which is ideal for steep working positions.

The engineers at Liebherr placed the VarioBase support technology at the focus of the structural steel construction when creating the concept for the new crane. This makes the new LTM crane the first to have an asymmetrical support base, with the width being 7.4m at the front and 8.1m at the rear.
