MEILLER at bauma 2013
Efficiency and safety
With a total of 24 exhibits at the venue of bauma 2013, the world's leading trade fair, the traditional brand demonstrates its role as the international market leader for tipper superstructures - while also taking the technological lead when it comes to the efficiency and safety of vehicles. On a stand area of 954 square metres, MEILLER presents the complete spectrum of its product range to its visitors. However, this presence is not restricted to its own stand, as innovative superstructure products bearing the MEILLER brand are visible on the stands and open spaces occupied by truck manufacturers where they enjoy immense popularity.
The Munich enterprise views the new year with optimism, as the production capacity utilisation in all plants corresponds to a high level of orders in the building industry, ensuring a continuous and stable demand for tipper and waste management superstructures - both in Germany and throughout Europe. Strong growth is rec-orded on the Russian market, while a lively interest in state-of-the-art MEILLER superstructures characterises Northern European premium markets. The manufacturer is expanding its product port-folio here in a targeted manner.
Taking the offensive with the latest tipper technology
A new generation of i.s.a.r. control
The MEILLER brand has traditionally been a synonym for tipper vehicles. There is a good reason for this, as the inventor of the hydraulic tipper subjects its products to continuous further devel-opment. The same applies to the latest component, i.s.a.r. control - the innovative electronic system for control of the superstructure and accessories. Taking the place of classic feed valves in the vehicle interior, it actuates the superstructure through wireless control. Following its presentation at bauma 2010, the i.s.a.r. control system was revised to enhance user-friendliness and now includes considerably expanded functions.
Lessons learned from the practical experience of customers have been resolutely implemented during development. With its yel-low/black signal colouring, the control unit now rests in an ergo-nomically located charging cradle, while the rechargeable batteries are supplied electronically by the on-board electrical system. When inserted in the charging cradle, the control unit communicates using a fixed cable link via MEILLER CAN bus, ensuring absolute freedom from interference. Regardless of the mode selected: the advanced radio modules enhance interference resistance and range considerably.
The control unit is easy to handle and has been improved in many respects. For example, the Start/Stop button for the engine is now positioned in the middle of the keypad. And there is a good reason for this. If used intelligently, considerable fuel savings can be achieved without limiting functions. "An annual saving of up to 800 litres is possible", estimates MEILLER's Head of Engineering, Uwe Meissner, "and, with only 10 loading and unloading cycles per day, the customer saves up to 1,200 Euros per vehicle each year". Strict efficiency and safety requirements are met when the driver activates the safe lowering function. The new function, which in-volves the automatic lowering of the tipper body with a safety check, was developed together with the trade association. Around 30 seconds are saved for every tipping procedure, equivalent to a time saving of up to 40 minutes per week or an increase in produc-tivity of two per cent.
The user interface now also has a night design to facilitate use in dark surroundings. The keys are backlit with robust, energy-saving LED lights which switch on automatically in poor lighting conditions, ensuring safe operation.
Far more mundane, but just as important on a day-to-day basis: MEILLER now provides precision-fitting belt holders, clips or mag-net attachments for operational use to prevent the misplacing or loss of the flexible device.
The sophisticated modular system structure enables the achieve-ment of upgrade and retrofitting solutions for first-generation equipment.
Optimised payload or heavy-duty labourer
Mounted on the chassis of all well-known truck manufacturers, the three-way tipper from MEILLER is the company's high volume product. It is used on practically every class of commercial vehicle - from heavy four-axle vehicles to light 3.5 t trucks. A robust floor and high steel side walls make it ideal for heavy work, while alu-minium profile side walls ensure that the customer enjoys opera-tional flexibility which suits the dimensions involved and a consid-erable gain in payload. Up to 500 kg are gained in a tractor and trailer combination (3-axle tipper plus tandem trailer) without im-pairing stability and durability. The MEILLER trailer is distinguished by its own sturdy qualities: the box frame design of the 2-axle trailer offers considerable load reserves in off-road use.
The 4-axle tipper, another tough contender, is mounted on the brand-new Mercedes Benz Arocs chassis. The overall technical weight of the off-road truck is up to 41 t, and the MEILLER three-way tipper (DSK 428) is also designed to be suitably robust. The highest level of quality has been combined with innovative solu-tions. Using remote control, the sturdy underride guard at the rear is raised hydraulically in off-road terrain, increasing the slope angle. A function which is also required during road finisher operations - and saves the driver a lot of strain during each tipping procedure, allowing him to stay in the cabin and saving time. The new Mercedes tipper is optionally prefitted ex works for the i.s.a.r. con-trol system, with the control unit resting on the left on the A-post.
To suit price-conscious markets, MEILLER supplies largely stand-ardised tipper products designed as 3 and 4-axle variants. The robust rear tippers from Munich enjoy a high degree of acceptance in many countries. Practical equipment and reliable basic functions ensure that they can withstand even the most severe operating conditions.
Semi-trailers with high payloads and reserves
MEILLER addresses customer demands for greater productivity with the new semi-trailer generation. They weigh a half a tonne less than their predecessors when empty. However, this reduced tare weight in no way diminishes other classic MEILLER strengths: robustness, reliability and resistance to wear. The new tipping semi-trailers are mounted on a newly developed steel chassis, and customers can choose between steel or aluminium tipper bodies to suit the job in hand. The steel halfpipe body makes the new 3-axle semi-trailer an all-rounder. The chassis concentrates material strength where it is needed, with the meticulous design being based on the finite element method (FEM). About 250 kg have been saved on the frame front end, corners and skid plate alone. The tipper bodies are up to 300 kilograms lighter. The new steel all-rounder semi-trailer may legally carry a half a tonne more, rep-resenting a considerable gain in payload when transporting bulk materials. The operator need not fear any disadvantages during day-to-day use. Solidity is decisively influenced by the number and positioning of the cross members, and the technicians in Munich have avoided any compromises here. The tipping shaft has been designed with the familiar robustness, and the MEILLER hydraulic ram is no heavyweight. The high-performance high-pressure sys-tem is regarded as the lightest of its kind in this sector.
An Austrian speciality, the "Baumeister" tipper from MEILLER, is becoming increasingly popular in other markets. The customer receives the complete vehicle as a 2 or 3-axle model, combined if requested with a three-way tipper and crane assembly. The loading platform can accommodate container widths when transporting construction materials. A tested lashing system offers versatile load securing options (e.g. lashing down over the side walls) and can achieve lashing forces of up to two tonnes.
As a rear tipper, the 4-axle Mercedes Benz Arocs is designed with a tailored halfpipe tipper body. The halfpipe superstructure is a proven design which has once again been optimised further with regard to higher payloads. Without limiting transport flexibility in any regard, the high-quality steel used in the body has a hardness of 450 HB, thus minimising wear and maximising resistance to buckling.
A 4-axle model with smooth superstructure panels is the new specialist for Scandinavian markets. The tailgate is divided horizontally, as is usual in Northern Europe. The concept encompasses a frontend ram and stabiliser, while the hydraulic pump is actuated by the engine power take-off. A tipper body vibration system replaces the heating system, and the trailer coupling is lowered for the tractor and trailer combination typical in these countries.
Asphalt tipper bodies for 3 and 4-axle tipper chassis are a MEILLER speciality. Up to twelve cubic metres of road surface material ready for laying can be transported to the site in this manner. The asphalt tipper body can be optionally fitted with a plastic shell to provide thermal insulation, thus maintaining the heat in the construction material and extending its processing time.
MEILLER tarp systems for tipping vehicles
The topicality of load securing has also grown in relation to bulk material transportation. ".... pertinent directives should be observed" is the description given in Paragraph 21 of the German Road Traffic Act (Strassenverkehrsordnung) with regard to securing loads. The absence of tarpaulins, the usual solution for bulk material transportation, on the tipper vehicle may prove very costly for the operator and driver in the event of an accident. MEILLER now provides a complete range of sliding and roll-up tarp systems for all three-way and rear tippers. The customer can choose between a simple manual crankoperated system or tarps powered by an electric motor. Uwe Meissner, Head of Engineering, recommends the motor-powered option: "Time is money, it's simply quicker, and the turnaround speed is increased as a result." Pushbutton operation (i.s.a.r. control) from the cockpit saves time. In addition, bulk material loads and empty runs secured or covered with tarps reduce fuel consumption, as wind tunnel trials conducted by commercial vehicle manufacturers have indicated. "Everything from a single source" is an argument in favour of MEILLER tarps. "When all is said and done, the quality of the transport solution is governed by the interface solutions", explains Uwe Meissner: "We do not accept compromises at the expense of our customers."
New products and comprehensive model care for MEILLER interchangeable body systems
Skip handlers and roll-off tippers from MEILLER enjoy an excellent reputation in the construction and waste disposal sector, being held in high regard as productive and sophisticated systems. Company technicians make enormous efforts to achieve the proverbial MEILLER stability. Enormous strength is guaranteed by enclosed high tensile steel frame profiles. Hydraulics and kinematics are company developments, with MEILLER being the only market player to manufacture hydraulic components such as pumps and cylinders. Even the steel tubing is produced by MEILLER in Munich.
MEILLER presents the roll-off semi-trailer at bauma 2013 as the top model among roll-off tippers. The advantage of the 40-tonne model is the high level of payload reserves. It can accommodate any roll-off container up to approx. 7.25 m, regardless of the contents. The semi-trailer has a universal fifth wheel height (1,100 mm) and rolls on low profile tyres to enable it to accommodate containers of a legal height. A further advantage for the operator is the new application options for underused semi-trailer tractors which only require a single tipper hydraulic system.
The company focuses in all cases on a modular system for its roll-off tipper and skip handler superstructures, with the specifications of the standard for the securing of loads on road vehicles (Ladungssicherungsnorm) being rigorously adhered to during development. In compliance with the VDI 2700 (Sheet 17) standard, the new MEILLER skip handler superstructures are optionally fitted with three tipping hooks for operation of both new change-over skips with two pivot bearings and older containers with only one pivot bearing. Continuous further development ensures a technological advantage, an advantage which MEILLER change-over skip superstructures now also profit from. An example is the hydraulic container lock which is certified in compliance with current regulations. Integrated in the loading platform, it adapts to and secures containers of all types, both in and counter to the direction of travel. The driver operates it from the cockpit - speedily, safely and with maximum ease.
Unit operation with i.s.a.r. control
The i.s.a.r remote control unit facilitates operation of the superstructure considerably. Instead of the usual valve control using the feed valve unit in the driver's cab and the feed valve for tipping located on the side of the superstructure, the driver only needs the signal yellow remote control. By pushing buttons and using a thumb wheel, he can control all superstructure functions from the cockpit or in a large radius around the vehicle. The operating logic is simple, and the buttons are clearly marked and illuminated at night. All necessary functions are integrated, and the control now includes a Stop-Start button for the vehicle engine. After all, even brief phases without the engine running save fuel and reduce noise and pollution emissions - not to mention the costs involved. A further argument can be made in favour of the networked electronics, as unnecessary movement by the operator is saved, the time required for each loading cycle is reduced further and both operating ease and comfort are decisively improved.
"Higher productivity" was also stipulated in the specification for the new generation of transport trailers for skip handlers and roll-off tippers. Despite a comprehensive range of complete equipment (Smart Board, fairing, floodlight), the new tandem axle transport trailer is considerably lighter. Careful design engineering using the finite element method (FEM), production using high tensile finegrained steel and axles with optimised weight characteristics enable a further reduction in the tare weight when compared to the predecessor models. The low transport height of the MEILLER trailer is achieved with smaller 17.5 inch twin wheels, with the air suspension being bled automatically during uncoupling. All conventional skips are hydraulically secured with an internal lock. An attractive lateral underride guard conceals lockable toolboxes.
