Compact Crane LTC 1050-3.1
Liebherr unveils its new LTC 1050-3.1 compact mobile crane, the successor to the LTC 1045-3.1, at the Intermat 2015 in Paris. The partial use of an even stronger fine-grain structural steel and improvements in the boom telescopes mean that the load capacity has been increased yet again whilst the dimensions have stayed almost identical. The Liebherr innovations VarioBase® and ECOmode mean that crane operators can use the new LTC 1050-3.1 with even more safety and efficiency.

Variable, highly compact single-cab crane
Liebherr unveiled its LTC 1045-3.1 compact crane with a completely new cab concept at the Bauma 2010 and this has now been continued with the new LTC 1050-3.1: For driving on the road the cab is moved to the front of the vehicle using a telescopic arm. In this position the crane driver has better visibility and a good driving position, particularly at high speed. The optional lift cab which can take the cane driver to an eye level of 7.8 m opens up new areas of use and advantages over conventional machines. The drastically improved line of sight to the assembly situation enhances safety for many crane jobs. This is why the majority of operators of the LTC 1045-3.1 have decided to purchase the lift cab.
ECOmode for more efficient mobile crane use
Liebherr has developed a special ECOmode for mobile cranes in the load-sensing range to reduce the cost of crane use whilst also reducing noise emissions. Crane drivers do not know the perfect engine speed for the required working speed. This results in them mostly operating with too high an engine speed. This particularly applies to movements in which a speed well above idling speed does not produce any major additional increase in working speed. Examples of this include luffing down the boom or lowering the hoist unit.
In ECOmode the crane driver sets the required working speed using the control lever. The LICCON2 controller then calculates the perfect engine speed for it. This value is set on the crane engine using the engine control unit. The result of this adjustment of the engine speed compared to using a constant and therefore mostly excessive engine speed is to reduce fuel consumption and minimise noise emissions.
Practical boom system
The new LTC 1050-3.1 has high load capacities over its entire working range. It is considerably more powerful than comparable city cranes on the market. The strong telescopic cylinder and the correspondingly enhanced crane controller on the LTC 1050-3.1 allow heavy loads to be telescoped which is particularly beneficial for installation work in factory buildings.
The 6-piece 8.2 m - 36 m telescopic boom is extended and bolted fully automatically using the telematic controller, some 10,000 of which have now been fitted. The 7.5 m - 13 m double folding jib includes a 1.5 m assembly jib which can be set to an angle of up to 60°. The assembly jib and an optional second winch make the LTC 1050-3.1 ideal for assembly work in very constricted areas and in low industrial buildings. A 3-roller compact hook block with a double hook is available to use the perfect hoist heights for these applications. The maximum hoist height is achieved with a hook traverse which is installed instead of the roller insert in the assembly jib.
