Première at Liebherr: Three new Telescopic Handler Models

TELFS/AUSTRIA, November 4, 2014 – Liebherr is presenting three new telescopic handler models with 7 m lifting height. During development, demands from companies in the construction industry and equipment hire were at the forefront. The basic model of Liebherr's new telescopic handlers with 7 m lifting height is the TL 432-7 with a lifting capacity of 3.2 tonnes.

Based on this standard model, the machines are also available as TL 436-7 and TL 441-7 versions with lifting capacities of 3.6 and 4.1 tonnes. The new models offer a  broad spectrum of use allowing challenging construction tasks to be performed reliably and efficiently.

The three telescopic handler models are powered by a new turbocharged Deutz construction machine engine with 74 kW / 101 HP. This engine is equipped as standard with an oxidisation catalyst and meets the requirements of the IIIB / tier 4i emissions legislation. For deployment on steep gradients where a higher pulling force is needed, Liebherr offers a larger capacity engine with an output of 90 kW / 122 HP and a greater hydraulic delivery rate.

The hydrostatically driven fan is regulated electronically and the cooling output is set variably depending on the ambient temperature and operating conditions. This enables a fuel saving, the noise emissions can be reduced and general efficiency during operation is increased.

Sturdy and universally deployable

The machines impress with their stability during loading and lifting. The newly designed frame and the balanced wheelbase give them a low centre of gravity. The heavy duty telescopic boom is articulated at a point deep in the frame. Powerful friction bearings allow smooth guidance with heavy loads and offer a high lifting force.

High performing working hydraulics and the trusted hydrostatic travel drive on the telescopic handlers facilitate purposeful and fast operations as well as short working cycles. The infinitely variable controls and the fine response of the hydrostatic travel drive ensure precision and rapid manoeuvring and also jolt-free driving without shifting operations across the entire speed range.

The rims and axles designed specifically for the equipment - the 45% self-locking limited slip differential on the front axle and the particularly wide swing angle of the rear axle - not forgetting the high ground clearance - guarantee safe work and good off road capability of the new telescopic handler. The compact machines are ideally suited for use in tight operating conditions thanks to their great manoeuvrability.

Three different types of steering – front wheel steering, all-wheel steering and crab steering – can be individually selected. A standard LED display informs the driver when the wheels are in a neutral position.

Safe and precise operation

The greatest importance was attached to the comfort and safety of the driver during the development of the equipment. Ergonomic control elements in a generously-sized driver cab allow work to be carried out in a relaxed manner. Large window panes, an uninterrupted windscreen, a newly designed driver console as well as the standard tilting steering column and low articulation point of the boom guarantee all-round visibility.

The acoustic and visual overload warning system provides continuous feedback to the driver about the current load situation of the machine. The standard load torque limiter also automatically regulates the speed of the working hydraulics and thereby facilitates a safe approach to the maximum rated load. In the event of overload, the functions that would otherwise lead to the machine tipping over are blocked. Only movements that allow the equipment to be moved back to the safe working range are then possible.

The standard end position damper for lifting, lowering and telescopic retraction as well as the pipe breakage protection in the hydraulic cylinders makes it possible to move the load with a particularly high level of safety. The automatic parking brake prevents the machine from rolling away unintentionally on gradients.
