Definitions
- the invention relates to a reach truck after the upper grip of the Patent claim 1.
- a reach truck is characterized in that the up to a high altitude extendable mast with its mast holder also arranged horizontally displaceable is.
- a fork for carrying the load is guided adjustable in height.
- the Storage of the mast holder takes place on a frame or chassis of the truck a cabin or so-called cabin box is placed.
- the cabin is on the the forks opposite side open for entry. It contains one Driver's seat with an arrangement transverse to the longitudinal axis of the truck. In the area of seated driver are a steering wheel and various instruments and Controls for the individual functions of the reach truck.
- On both Sides of the chassis are mounted parallel to the forklift wheel arms, and a steerable drive wheel is usually located at the rear lower end of the chassis on the longitudinal axis of the truck.
- a battery is in a room that is arranged below an armrest next to the driver's seat and across the Longitudinal axis runs.
- a reach truck needs at least two electric motors, namely one for the drive of the steerable drive wheel, one for the hydraulic pump for the Lifting and lowering operation and often another for the power steering.
- the lifting and Traction motors including their gears are in a socket-like fairing arranged inside the cabin, on the upper side of the driver's seat is arranged. In front of the driver's seat is a room that faces down through a floor slab is completed. At the bottom plate are a pedal for the brake and a pedal arranged for the speed specification.
- the power units contain high-performance semiconductors that are naturally experience a strong warming and therefore need to be cooled. Furthermore Such power units form sources of electromagnetic radiation. For Operators of electrically operated equipment is required that the inputs and Electromagnetic energy does not radiate a desired value exceeds.
- the power units for the respective engine compact form and the housing with a heat sink or the like provided, which provides the necessary cooling of the power semiconductors.
- This space above the battery has a relatively small height, because it is determined by the predetermined height of the battery on the one hand and the Height of the armrest of the driver on the other hand. It is possible, the armrest higher position, but this also raises the other levels must be, d. H. Height of the driver's seat and the bottom plate. This is running Requirement to keep the height of a forklift low, so that it is necessary in Containers or wagons can enter. Moreover, a low entry level advantageous because the risk of accidents when getting off is reduced.
- the invention has for its object to a reach truck to that effect improve that at low height of the truck, an arrangement of the Power units is reached at the length of the energy-carrying lines drastically reduced. In addition, improved ventilation and a better Protection against the emission of electromagnetic radiation should be sought.
- the reach truck according to the invention is in a space below the Base plate a support plate to the space laterally delimiting frame parts mounted on the side by side, the two power units are attached.
- the truck uses a hydraulic braking system, it is usually below the bottom plate is arranged a master cylinder, which upon actuation of the Brake pedal is pressed in turn.
- the electric motor for the To arrange power steering in the space below the bottom plate is also known.
- Reach truck according to the invention has been recognized that also another Arrangement of the electric motor for power steering comes into question. While in the known case of the electric motor for power steering via a chain with a Sprocket of the fifth wheel cooperates for the steerable wheel, at the Reach trucks according to the invention are provided, for example, with the Sprocket of the stool directly to let a pinion interact, the on the shaft of the electric motor is arranged. Consequently, the electric motor is located for the power steering in the same room as the drive motor.
- a electric signal generator for the speed and brake pedal requires one low space requirement in the installation space below the bottom plate.
- the inventive design of the reach truck has several significant benefits.
- the installation space used does not lead to an increase in the Bottom plate and thus the overall height of the reach truck, rather allows he chose a height measure of minimum size. This leads to a favorable Entry height.
- the power units can be used in a pre-assembly on the Carrier plate are attached. However, it is also possible the power units after mounting the carrier plate to assemble. The latter would then be the case if the support plate - made of steel - in the space below the Base plate would be welded.
- Another advantage is that a good and faster access to the power units is obtained, especially during the Service or even when replacing individual power units the effort reduced.
- Another advantage is the saving of electrical cables. It requires two wires from the battery into the power unit receiving space. The connection cables to the electric motors are conceivably short, since these are in relative short distance to the power units are arranged. Besides, no Clipboard required.
- Another advantage of the invention is that of the power units enclosing space consists of steel parts and thus a flawless Shielding against electromagnetic radiation and irradiation is ensured. Furthermore, it is advantageous that the entry height for the cabin is low, whereby the Accident risk is reduced. Above all, the invention enables an effective Cooling of the power units.
- an embodiment of the invention provides that at the Support plate below each power unit one fan at a distance from the bottom the power unit is attached. It is understood that by the fans conveyed air in a suitable manner against the cooling surfaces or body of the Power units is directed, which corresponding openings in the carrier plate presupposes.
- the space below the bottom plate in a the upper and lower compartments are subdivided and the fans the air from the upper compartment Encourage compartment into the lower compartment or vice versa.
- the room below the Base plate is in its lateral dimensions depends on the width of the Reach truck. It is known that this width varies depending on the application choose.
- the carrier plate with the power units unit dimensions regardless of the width of the reach truck, which is desirable it is advantageous to make the carrier plate slightly smaller than the cross-sectional area of the space below the floor slab. It is therefore appropriate between Support plate and the one side wall of the frame to leave a gap, the optionally of a corresponding sealing means, for example one flexible strip of plastic or the like, is sealed to upper and to separate the lower compartment substantially airtight from each other.
- a corresponding sealing means for example one flexible strip of plastic or the like
- edge sections of passenger cabin panel and frame each other in the Spaces overlap so that the air flowing into the room from the outside first deflected downwards before entering the room or upper compartment.
