The new 5 to 8-tonne trucks in the 39x series from Linde Material Handling
Soon to be presented to the trade for the first time at the CeMAT 2008: the new 5 to 8-tonne diesel and LPG trucks from Linde. They are set to become benchmarks for their class, just as their predecessors were.
With spacious and comfortable cabs, a view through the mast that had been increased by around 20 per cent and powerful engines with emission values far below current emission guidelines, the Linde H50 to H80 models have once again set the benchmark in the 5 to 8 tonne load category.
This is supported by the many design improvements that they feature, which make this powerhouse even roomier and more comfortable, as well as increasing the view through the mast by nearly 20 per cent. Furthermore, modern, powerful stage 3 compliant engines ensure that the emission values are far below current guidelines. This successful range has been extended to include a lifting capacity of 8 tonnes at a load centre of 1100 mm, which addresses customers' demands for trucks to carry ever larger loads. Major service intervals have been extended from 500 to 1000 hours, improving uptime and reducing lifetime costs.
With the models H50 to H80, Linde Material Handling has brought the entire 1.4 to 18-tonne engine powered product range right up-to-date with cutting-edge technology. "Our high-power, safe, comfortable and easy-to-service trucks enable us to meet the requirement for optimum performance at low operating costs," said Theodor Maurer, the member of the Management Board with responsibility for sales at Linde Material Handling. "And that really strikes a chord with our customers, because people are increasingly realising that it is not the purchasing costs that are decisive. Instead, it is the overall cost, including personnel, servicing, financing and energy costs, which determines your success."
Improvements in detail
The operator is one of the decisive success factors when using fork lift trucks. A comfortable, ergonomic working environment that provides protection against strain and fatigue was therefore once again an important requirement for the company in this new development. The operator can access the workplace via three steps at heights of 40, 70 and 105 cm, each clearly visible from above, and access grips are fitted as standard to the overhead guard support and engine cowling. The cab has been widened by 10 cm on each side of the windscreen to extend the viewing angle past the outside edges of the mast by a factor of 3.5. Operators will particularly benefit from the extra comfort and safety when loading and unloading HGVs. The two control levers for lift/lower, tilt and auxiliary hydraulics integrated in the armrest provide greater operating comfort. The Linde Load Control—which is a trademark of every Linde counterbalance truck in the 1.4 to 18-tonne category—enables precise, fingertip control of the mast functions and significantly increases the truck's economic efficiency. The new design includes features such as a full suspension comfort seat, adjustable steering wheel, large foot well, twin accelerator pedals, head-up instrument display, a control panel within easy reach, interior lighting and storage space, as well as other modular options such as heating, air conditioning and a radio.
Innovative mast concept
The new models will mainly be used in the building materials industry, the retail sector, the beverage industry, the iron and metal-processing industry and the paper and printing industry. Loading and unloading bulky loads to heights up to 8.5 metres is all part of daily business in these industries. Clear views, high residual capacities and low mast deflection are imperative if loads are to be handled quickly and safely. Linde Material Handling has further improved the mast design to achieve these objectives. Overhead tilt cylinders guarantee high residual capacities due to the high leverage. They also enable the use of narrower mast profiles behind which the lift cylinders are located. Linde is proud to announce that the view through the mast has been extended by nearly one-fifth in comparison to the previous range. The new triplex mast, developed by Linde, offers the operator an 18 per cent larger field of vision. Linde's torsion support and the torsion rack is a further excellent feature of the mast design. This unique system connects the mast to the counterweight and stabilises it against lateral torsion. The torsion rack attached to the front of the mast is fed between the torsion supports on rollers, thus limiting mast twist oscillation. The result is a mast with much higher rigidity, even at high lifts with large or swinging loads. This solution, which is an industry first, will enable loads to be handled quickly and safely in everyday situations.
Linde Load Control enables precise, fingertip control of the mast functions, providing even greater operating comfort. Not only this, but the new design includes features such as a comfortable seat (swivelling chair also an option), adjustable steering wheel, large foot space and twin accelerator pedals.
High power, low emissions: the engine
The new 5 to 8-tonne trucks are powered by a Deutz turbo-diesel engine with common rail direct injection and intercooling. Engine performance is rated at 87 kW at 2200 rpm, with maximum torque of 472 Nm achieved at 1600 rpm. The engine is in compliance with the emissions directive 2004/26/EC Stage 3A in force since 01.01.2008, and falls significantly below the limits for carbon monoxide, hydrocarbons, oxides of nitrogen and particulate matter.
A variable pump for operating hydraulics
Linde's powerful, low-maintenance hydrostatic drive is responsible for transforming the diesel or LPG engine into a precise driving force. The lift and tilt functions are now powered by an axial piston variable pump developed by Linde instead of the previous fixed-displacement pump. This significantly increases the volume of pumped oil with positive results for the mast's lifting speeds, which have increased by up to 30 per cent. Tasks involving high lifting, often seen in the beverage and paper industries, will see a particular benefit from this significant increase in performance. The oil volume for additional hydraulics has also been increased. This enables quicker operation of attachments such as rotating clamps, and therefore higher turnover. But the advantages of the new variable pump don't end there. The pump always adjusts the pumped oil volume to suit the required output, thus maintaining a low noise level and reducing fuel consumption. Furthermore, the oil lasts longer due to the lower demand, which results in benefits for the environment and keeps maintenance costs down.
With a lifting capacity of 8 tonnes and a load centre of 1100 mm, the H80/1100 diesel and LPG trucks can handle more pallets per lift in the beverage industry.
