The telescopic crawler cranes in the LTR series combine many of the benefits of all-terrain cranes and crawler cranes. The excellent manoeuvrability of the crawler travel gear enables LTR cranes to be used on any terrain.
And what’s more, the crawler travel gear means that unlike all-terrain cranes, no outriggers are required – which means an LTR can also be moved with the load on its hook.
The telescopic boom whose concept has been adopted from all-terrain cranes enables a wide range of radii to be achieved quickly and easily compared to conventional crawler cranes. And what's more, the boom can even be extended and retracted with a load on the hook.
These technical features mean that LTR cranes are enormously flexible in action. Frequent areas of use for them include prefabricated part assembly, long term use in the energy sector, auxiliary crane jobs for erecting wind turbines and even infrastructure projects.
Our LTR cranes feature extremely compact dimensions. The crane can be self-erecting as an option. The basic machine is transported to the site on a low loader and the central ballast, cross carrier, crawler carrier and turntable ballast are installed without an auxiliary crane.
Setting up the crane
The installation of ballast and additional equipment is designed to be quick, safe and convenient. There are access ladders, grab handles and railings to ensure the safety of the operating personnel.
Tilting crane cabin
The crane cabin can be tilted backwards and provides a comfortable, functional workplace. The controls and displays are arranged ergonomically. This ensures safe, fatigue-free operations.
Telescoping crawler carriers
The chassis on LTR cranes can be extended hydraulically to suit different crawler carrier widths. LTR models can complete crane work on all crawler widths and are kept safe by the LICCON overload system. And the track width can be adjusted when the crane is fully set up.
Crane operations at a lateral angle
The standard programmed lifting capacity tables for crane operations with the main boom or erection jib up to a ground incline of 4° opens up additional possible uses for the machine. The rope pulleys in the boom head and assembly jib are made of steel to ensure that it can still manage large lifting capacities at these gradients.
Working with remote control
LTR cranes and full crane operations are also possible from outside the crane cabin – using our BTT remote control. This can also be used to adjust the crane’s track width.
The LTR 1060 telescopic crawler crane put its skills to the test carrying out tunnelling work on the Swiss Gornergrat railway, the second highest mountain railway in Europe. With technical support from the Liebherr specialists it navigated a route beset with gravel, bends, and enormous gradients. This enabled the telescopic crawler crane to demonstrate its off-road capabilities once again in extreme conditions.
Supplying the world crane market out of Ehingen since 1969, Liebherr is today the leading manufacturer of all terrain cranes. With the biggest product portfolio of 40 different cranes on wheels or on crawler tracks, we are renowned for our top technical level and innovative crane concepts.
Setting standards in the industry, we are responsible for designing and building a whole host of new technical ideas – just like the rough terrain cranes, the latest distribution to our product portfolio.
Liebherr cranes are reliable. When you need service for our products, you can rely on our global service network of more than 80 own sites in 35 countries. That network is backed by 70 years of history dating to 1949.
