Unitrac 112 LDrive

The stepless traction drive, rear and front PTO shafts and the working hydraulics with variable displacement pump make the Unitrac the ideal equipment carrier for any winter road clearance duties. Gritting and sweeping tasks as well as snow clearing with a conventional or a rotary snowplough is child's play with the 4-wheel steering, even in narrow alleys. 5,000 kg payload and good tractive power make heavy transportation work possible.

Cab Tiltable comfort cab

Optimum all-round view: You have everything in your field of vision: the front working area through the heated panoramic windscreen, to the side an unobstructed view through the large glass doors with wide-opening sliding windows. The rear-view mirrors with integrated additional turn signal indicators can be adjusted electrically and are heated.

Comfort equipment: The roomy comfort cab is accessed easily through the wide-opening doors. The automatic door function opens the rear window upon entry, facilitating soft door closure with optimised cab ventilation. The non-slip storage compartments and nets are practical, as are the large drink holders in the centre console.

LDrive comfort seat

LDrive comfort seat

The air-suspension seat in the Unitrac 112 LDrive with 8-way adjustment offers maximum safety and comfort. The high backrest with head restraint and integrated 3-point seat belt together with the low frequency air suspension relieve the back during prolonged use. Seat heating provides warmth in winter.

Ergonomic interior

Ergonomic interior

The steering wheel can be individually adjusted for height and angle to suit the driver. The central information panel provides a clear overview of important vehicle information and control displays. Other information such as the total and daily operating hours or the time of day can be read from the additional IBC monitor. All control levers and switches are placed around the driver in an optimum manner. The switches and displays in the Unitrac are illuminated.

Corrosion protection

Corrosion protection

The entire vehicle chassis and the comfort cab are painted using a particularly high-resistance cataphoretic immersion priming process. Battery box, fuel tank and optionally available tool boxes are made from corrosion-resistant plastic.

IBC monitor

IBC monitor

The driver has an overview of important equipment information on the IBC monitor: axle load, gross weight equipment status are determined via the TRAC Link system. Instructions, vehicle or hydraulic settings 
as well as images of the reversing and side cameras are displayed as required.

Cab mounting

Cab mounting

The comfort cab is mounted on 4 hydro-rubber elements and is thus particularly vibration-resistant. A quiet working place results from enclosure of the cab. Comfort as you know it from a passenger car.

Cable opening

Cable opening

A special cable opening is a standard feature of the Unitrac. With this, various cable connections can be fed into the cab without disturbance from water, dust or noise.

Roof console

Roof console

Radio and tachograph positioned in the roof console for easy access. Storage compartments for vehicle papers or sunglasses can be found behind the sun visors. In addition to the interior lighting, reading lights are integrated for the driver and passenger. The stepless automatic air conditioning system provides an optimum working climate.

Tools-free tipping

The complete cab can be tilted 50° to the side to provide a high degree of maintenance friendliness. Thanks to the tools-free hydraulic tilting mechanism, the engine and gearbox compartment are freely accessible in just a few steps.

Engine

The 4-cylinder turbo diesel engine in the Unitrac 112 LDrive has an output of 79 kW/107 HP at 2300 rpm and generates 420 Nm of torque between 1100 and 1400 rpm. The engine, which has a cylinder capacity of approximately 3 litres, and runs particularly quietly, fulfils the exhaust gas criteria of EURO 6. The Unitrac 112 LDrive is thus particularly environmentally friendly and has received the "green label" for inner cities in Germany.

Trouble-free particulate filter

The exhaust gas after-treatment system in the Unitrac 112 LDrive comprises two modules. The particulate filter system (DOC & DPF) which is located directly in the engine compartment, collects 99.9% of the fine particulates. The maintenance-free filter system regenerates automatically. In the downstream SCR system behind the cab, the exhaust gas treatment process is completed with AdBlue.

Consumption-optimised peak performance

Due to the exact monitoring of inducted air and engine temperatures, particularly precise fuel injection is possible. This high-performance engine is characterised by optimum power delivery and low consumption. The engine is particularly service-friendly due to 2-valve technology and maintenance-free hydraulic tappets and 
closed crankcase ventilation.

Gearbox

The stepless CVT transmission used in the Unitrac 112 LDrive was developed together with ZF and produced by Lindner. Thanks to the mainly mechanical transmission of power with low hydrostatic proportion in the working driving range, the gearbox works particularly efficiently. A continuously variable driving speed is possible from -20 to +50 km/h at reduced engine speed.

Foot accelerator mode

for front-mounted equipment

In foot accelerator mode, which is known from transporters with manual transmission, the engine speed depends directly on the accelerator pedal. Nevertheless, the driving speed can be kept constant – this function is particularly practical for mowing or snowploughing activities.

Fine control and creeping

In creep mode, the foot pedal and the LDrive spread can be set to 15 km/h at the press of a button. In this way, the driving speed can be controlled extremely exactly when performing snowploughing or mowing tasks.

Hydrostat

with power splitting

The secret of the efficiency of the stepless Lindner CVT transmission lies in its predominantly mechanical transmission of power. The multiply-split power-shift transmission is supplemented with a compact and frugal 45 cc hydrostat.

LDrive operation

the simple rotary control makes every driver a complete professional

It is easy to drive the Unitrac 112 LDrive: start the engine, select the direction of travel, accelerate and steer. And for particularly efficient working, use the LDrive rotary control on the armrest. If "LDrive" is active, the driving speed is set dynamically and infinitely variably by turning the control. Quick-selection buttons are available for important chassis functions and driving modes.

Working hydraulics

with variable displacement pump

The Unitrac 112 LDrive works with an axial piston pump, which infinitely variably regulates the hydraulic output up to 88 l/min. The required volume of oil for the working circuits is always delivered, thus eliminating power loss. Up to 5 EHS control units and an EWS control unit with quantity presetting are possible. These work proportionally and are particularly sensitive. Fine setting of the hydraulics is performed via the IBC monitor. 
As with all Lindner vehicles, the Unitrac 112 LDrive also has an oil circulation system separate from the working hydraulics / steering and gearbox with separate cooling systems. A hydraulic output of 50 l/min is fully available from just 1,300 rpm engine speed.

Front circuits

The front hydraulic circuits are operated conveniently via a joystick. For this purpose, the front installation space is equipped with 2 double-action EHS control units (proportional, with floating position). If a snowplough or a front hydraulic is mounted on the attachment bracket, then these can be operated with the joystick using one hand. For example, mowing equipment or 
snowploughs can be powered in combination with the front PTO shaft.

Rear circuits

As standard, 3 control units are provided for the rear hydraulic circuits: 1x EWS and 2x EHS (DWS), that are also used as a hydraulic motor, e.g. for scraper / gravel spreader drives. Operation is carried out by fingertip on the control console or via the joystick. In total, up to 6 hydraulic control units (1x EWS / 5x EHS) can be installed. Operation of the hydraulics is easy to comprehend due to coloured labelling of all connections, switches and joystick assignments.

Operating assistance

via TracLink

When changing equipment, the TracLink system detects new attached equipment and indicates in the IBC monitor which connections are to be used by the equipment, which functions are operated and how, and with what hydraulic volume optimum utilisation results can be attained. In this way, even inexperienced operators can work like professionals.

All driving functions under control

The most important driving functions are combined in the LDrive controller: function buttons for creep mode, cruise control and floor accelerator mode are at the front. The rear buttons activate the all-wheel drive and differential lock. LDrive is activated by pressing the rotary control. In this way, the driving speed of the Unitrac can be accelerated or braked with infinitely variable control. The spread of the driving speed can be set via creep mode (e.g. 10 km/h).

High-performance chassis

High-performance chassis

The Unitrac chassis concept has already proved itself in more than 3,000 vehicles, in meadowland farming, with cable car and industrial customers and as a municipal service vehicle. Together with the rotating part between the front and rear chassis, independent suspension and hydraulic suspension cylinder with diaphragm accumulators guarantee optimum suspension comfort with the greatest possible off-road capability. Thanks to the rotating chassis, all four wheels are in constant contact with the ground and offer the highest possible traction. The standard mechanical level regulation provides the highest tipping stability on difficult terrain. As a result of the system's relatively short suspension travel, the upper edge of the load bed is particularly low in spite of large tyres being fitted.

4-wheel steering

The Unitrac 112 LDrive is available with an optional 4-wheel steering system. With this, the turning radius is just 6 m (3.5 m with 4-wheel steering). If desired, a crab-steering mode is available. Operation is easy and convenient due to the convenience reset and the display on the IBC monitor. The 4-wheel steering system can be switched off in any wheel position. The system automatically locks the rear axle as soon as the wheels return to the zero point. Various audible signals inform the driver of hazardous situations. This means that even inexperienced vehicle operators are always safe on the road.

Intelligent light

The Unitrac is equipped with LED rear lights and daytime driving light rings. The light-emitting diodes have particularly low energy consumption and, with a service life of more than 20,000 operating hours, will last for the life of a tractor. The Unitrac has powerful full LED headlights for daytime driving and dipped beam lights, which are ideally suited to night use with their high illumination. If desired, powerful LED work lights are available.

LED warning lights

For municipal use, highly visible LED rotating beacons and lighting bars are used. LED warning lights on the impact beam are fitted 
as standard on the municipal-use version.

Brakes

As standard, the vehicle is equipped with a 2-circuit braking system with internally vented disc brakes at the front and rear. Less pedal pressure due to the brake booster and reduced heat build-up increase comfort and safety. The Unitrac can optionally be equipped with an eddy current brake. The Unitrac 112 LDrive is available ex works with a compressed-air braking system or hydraulic trailer brake.

Parking brake

The Unitrac 112 LDrive is equipped with an intelligent electro-hydraulic parking brake with spring mechanism. Depending on the utilisation situation, this serves as an aid for setting off, for example on a slope, or as a parking brake. Operation is via the parking pushbutton on 
the centre console.

  • Internally ventilated disc brakes
  • Brake booster
  • Electro-hydraulic parking brake

Optional:

  • Eddy current brake
  • Compressed-air brake
  • Hydraulic trailer brake

The Unitrac equipment system

The four attachment points of the Unitrac enable many different application possibilities. A payload of up to 5,750 kg and a trailer load of 10,000 kg also make the Unitrac 112 LDrive ideal for heavy-duty transportation work – with full off-road capability. The engine power can be transferred to the drive unit via front, middle or rear PTO shafts so that the widest variety of attachments can be used. The 88 l/min output of the multi-circuit hydraulic system with variable displacement pump is available as standard via single-action or double-action EHS control units. Maximum hydraulic performance is available from an engine speed of just 1300 rpm. The sequence of oil supply to the control units can be prioritised. Time control and quantity presetting are standard. In this way, the Unitrac can be individually adapted to the respective use.

Axle load check on IBC monitor:

The Unitrac shows the driver the currently detected axle load for front axle and rear axle as well as the current gross weight on the IBC monitor. In addition, the TracLink system can also be used to display the current fill state of the installed equipment such as e.g. a gritter.

TracLink

The Lindner TracLink system makes the Unitrac 112 LDrive the most intelligent vehicle in its class: TracLink supports the operation of all attached implements. The electronic logbook simplifies maintenance and documents the use of equipment and routes. TracLink provides an optimum overall view of costs and fuel consumption data.

3 years' warranty – or longer if desired

The intelligent TracLink equipment detection ensures that optimally-tuned equipment is used that is operated with the right hydraulic volumes and PTO shaft speeds. Incorrect operation is prevented as an operating aid relating to the corresponding attached equipment is shown on the IBC monitor. TracLink helps with maintenance by providing a reminder of important inspections or service work (e.g. oil change). This is why Lindner provides a 3-year warranty as standard for the Unitrac 112 LDrive with TracLink. This can be optionally extended to a warranty of up to 6 years.

Integration of TracLink system partner

Integration of TracLink system partner

It is possible to integrate many common operating terminals from equipment manufacturers into the TracLink system. In this way, even elaborate sensors can be integrated into the equipment, e.g. for spreader quantity checking or road temperature detection.
