Definitions
- the invention relates to a reach truck according to the preamble of Claim 1.
- the load section usually has a number of mast sections Mast that can be extended to great heights.
- the load handler is usually a fork, with the fork tines within parallel spaced wheel arms are attached to the drive part and to Extend both sides of the mast away from the drive section.
- point such reach trucks also have an integrated sideshift.
- the load handler such as the fork
- the guide is guided on the mast and can be raised and lowered using the lifting and lowering device be raised and lowered.
- the invention has for its object a reach truck with sideshift to create, in which the operation is simplified and accelerated.
- the position signal given to the control device becomes.
- the control or regulating device controls all adjustment processes in connection with the load handler and the push mast according to one Actuation by appropriate handling or actuators in the cabin of the reach truck.
- the invention also sees either as special Actuator for the sideshift before, when it is actuated the sideshift is automatically moved to a specified position or training the usual actuator for the sideshift such that a certain actuation mode the automatic approach to the specified position causes.
- the given position will mostly be the middle position. It however, any position can also be specified.
- the respective position of the sideshift can be detected, can a setpoint generator for the sideshift drive according to its adjustment path or angle output a setpoint signal that on the control device is given to move the sideshift to a predetermined position. Therefore the sideshift can be set to any position, for example to Load a load in the specified position.
- the drive for the sideshift is initially e.g. the center position starts, the sideshifter should have an off-center position, if a lowering operation of the load suspension device is carried out via the associated actuators and / or a withdrawal of the mast is initiated. That way after the mast has been pulled back and the lowering process has been initiated manually the middle position of the sideshift is automatically initiated become. For the driver, the otherwise before the next stacking game the work process is eliminated.
- the reach truck shown in Fig. 1 is of conventional construction and has a drive part 10 and a load part 12.
- the load part 12 has a mast 14 several mast sections, e.g. can be extended to a height of up to 12 m and more.
- the load part 12 also has a load suspension device which is adjustable in height on Mast is guided.
- a prong 16 of a fork can be seen, the a carriage, not shown, is attached, which in turn can be moved horizontally is.
- the guide required for this is attached to the mast 14 in a height-adjustable manner, as is known per se with forklift trucks.
- On the drive part 10 are Wheel arms attached, which are spaced parallel on both sides of the mast 14th extend.
- a wheel arm is shown at 18 in FIG. 1.
- In the radars are each Load wheels stored.
- a steerable drive wheel can be seen at 19.
- the mast 14 can be moved horizontally with the aid of a guide (not shown further) away from the drive part 10 and towards it.
- a guide (not shown further) away from the drive part 10 and towards it.
- an actuator not shown, for driving the mast thrust intended.
- an actuator for in the cabin the lifting and lowering operation of the load fork or mast.
- the mast 14 its inclination can also be changed with the aid of a corresponding inclination drive, the tilt drive in turn via a separate actuator can be actuated.
- the wheel arms 18 can be seen as well as a side slider 20, which along a guide 22 is horizontally displaceable, as indicated by double arrow 24.
- the guide 22 is connected to the lifting and lowering means on the mast 14, the is indicated by dash-dotted lines in FIG. 2.
- the fork tines are 16 on the sideshift appropriate.
- An adjustment cylinder 26 engages on the side slide 20 in order to adjust it Double arrow 24 to adjust laterally.
- the adjusting cylinder e.g. an electric Drive may be provided.
- the load suspension device can only be lowered if if the sideshift has 20 center position.
- the middle position are the fork tines 16 in the middle between the wheel arms 18, such as is indicated by dashed lines in Fig. 2.
- the side shift must therefore 20 have center position.
- the analog sensor 30 generates an analog one Position signal according to the position of the slide 20 relative to one Center line 32 (Fig. 2), which indicates the central position of the slide 20.
- On Signal from sensor 30 goes to a display 32 in the cabin of the reach truck, so that the driver recognizes the position of the sideshift 20 located.
- the position signal of the analog sensor 30 also goes to a control and Control device 34, such as is used for reach trucks for the Lifting and lowering operation or moving the mast and lifting and lowering of the load handler.
- the device 34 is also capable of the position signal to process the sensor 30.
- At 36 is an actuator in the Indicated cabin of the truck, when actuated, the side shift 20 adjusted becomes. With the help of the actuator 36 can according to its deflection any position of the side shift 20 can be approached. This happens via the control and regulating device 34, which in turn sends a signal to a Control 38 gives actuation of the adjusting cylinder 26. Additionally or alternatively an actuator 40 can be provided, for example a switch button, when it is actuated, the control and regulating device 34 automatically switches to the center position of the sideshift 20 starts.
- Fig. 3 are the actuators 42 and 44 for the mast feed and that Lifting and lowering of the load handler indicated. You are also with the Control and regulating device 34 in connection. The corresponding drives are designated with 47 and 48 respectively. Is now by actuating the actuators 42nd or 44 retracting the mast 14 or lowering the load handler 16, the control device 34 determines whether the sideshift 20 has its center position. This is done by querying the sensor signal 30. If an off-center position is determined, the withdrawal of the Mast 14 or a lowering of the load handler 16 locked until the sideshift 20 has automatically moved from the drive 26 to the center position.
- An on-board computer 46 which also belongs to the reach truck according to FIG. 1, calculates the maximum driving speed for the driving motor, not shown Stipulation of stability criteria.
- Known stability criteria are, for example Load weight on the load handler, the height of the load handler, the Inclination of the mast, etc.
- the position of the sideshift 20 can Security criterion, which is also entered into the on-board computer 46 in order to be included in the calculation of the maximum driving speed.
