Power-line construction |
|
|
The Lännen machines are well suited to many power-line construction
tasks. Excellent on-road driving comfort and off-road robustness are
their basic strengths.
The machine range offers operators the solid controllability required for making way through tough terrain and stamina for erecting poles. The precise movements of the backhoe in combination with the fair margin of engine power enable even difficult operations to be carried out safely. The power-line construction machines are fitted at the factory with all the equipment necessary for that work. The Lännen 190 power-line system allows operatives to work safely at heights of up to 19 metres

Characteristics |
|
|
The Lännen Wheel Loader Backhoe is an excellent choice for professionals
involved in construction of open-cable power-lines and cable laying operations.
This machine, specially built for power-line construction, is capable of operating in confined yards as well as in congested streets, both in terrain and on the rail. Feedback gained from Lännen's customers has been fully utilized during the planning and manufacturing processes.

Off-road properties |
|
|
The off-road properties of the Lännen machines are unrivalled.
With the optional special tyres the machine advances even better
on soft ground without leaving any tracks.
Unobstructed and safe advancement requires proper armouring of the machine's underside and high ground clearance. The agile and well-balanced machine goes round any obstacles without marking them. By virtue of hydrostatic transmission the traction force is evenly distributed on all wheels. The operating controls in the rear enable the operator to concentrate on what he is doing, even while the machine is being driven forward.

Occupational safety |
|
|
The safety platform of aluminium for two people offers a fair-sized workspace for
operatives and their tools. A platform for one person is also available in case
small external dimensions are desired.
The automatic electro-hydraulic levelling system for the platform keeps the platform on a level during all phases of the lifting movement. Operational safety is ensured by providing both the cabin and the platform with a complete set of operating controls. Stepless control of the platform u sing only one lever. The set-up also comprises an emergency control system powered by a separate electric pump. Socket outlet for 24V and cabling for 200V voltage on the platform.

Pole grip |
|
|
A separate pole grip is attached directly to the end of the boom
and can be used simultaneously with the access platform.
The platform's featured quick-release hitch makes it possible to use the grip in places where space is limited. The platform is quick to remove, after which the movement speed of the boom increases significantly and the work proceeds much more quickly. Operating the grip is precise and easy using the switch on the control lever. |

Outreach |
|
|
The extensive outreach of the Lännen 190 also enables working
at high elevations. The maximum working height is 19 metres.
If the work does not require the maximum height to be used, then full advantage can be taken of the unit's outstanding outreach and extensive operating range. The maximum outreach to the side is over 12 metres.

Laying cable by ploughing |
|
|
An economical option for laying cables
Ploughing is an economical method for laying cables if the soil structure is suitable. Thanks to their versatile and powerful operating/drive hydraulics, different plough types are well suited to use as optional equipment for the Lännen machines. The featured hydrostatic transmission enables stepless adjustment of speed depending on the work situation. Operation of the drive hydraulics does not affect any other functions. A chain trencher can be applied for laying cables, if the soil is too hard for ploughing. |

Electricity or compressed air |
|
|
The LS hydraulics of the Lännen machines enables generation of
electricity or compressed air by means of hydraulics. You can go
on with the digging work despite the generator being in operation.
A great variety of different factory-fitted options is available depending on the user's requirements. The electric current generated by the generator located inside the rear frame is easy to connect to the cable of 220V leading to the platform. |
