Definitions

  • the invention relates to an industrial truck with a load suspension device and a Control device for controlling a lifting movement of the load suspension device, wherein the control device with at least one operable by an operator Control element for the lifting movement is connected.
  • the invention also relates to Industrial truck with a load handling device and a control device for Controlling a travel movement of the industrial truck, the control device comprising at least one control element that can be actuated by an operator for the Driving movement is connected.
  • An object of the invention is therefore to provide an industrial truck To provide, in which the function of the lifting device, in particular the achievable lifting height is automatically influenced depending on the load weight become.
  • Another object of the invention is therefore to provide an industrial truck in which the Travel speed with the load raised to the permissible level automatically is limited.
  • the first-mentioned object is achieved in that the Control device is connected to a load sensor, one of the weight of a generated on the load suspension device dependent signal and that the Control device is designed such that an upward movement of the Load suspension device is prevented if the weight of one on the Load suspension device load exceeds a limit weight. If the Operator lifting the load handler by means of the control element specifies, the control device checks the weight of the on the load handling device located load and prevents against that made with the control element Specification of lifting the load handler when the limit weight is exceeded is.
  • a first limit weight corresponds to a maximum load capacity of the Industrial truck. This first limit weight is fixed in the control device Are defined. When attempting a load exceeding the first limit weight lifting, the control device stops the lifting process immediately.
  • the control device is equipped with a Lifting height sensor connected, which is one of the lifting height of the load handler dependent signal generated and the control device is designed such that a second limit weight continuously depending on the current lifting height is determined.
  • the second limit weight is in the control device in Depends on the current lifting height. For this is in the control device the load diagram of the truck described above in electronic form displayed. If the operator tries to lift the load handler over the in view of the current permissible height, the Lifting process automatically stopped at this height by the control device.
  • the lift height sensor is particularly advantageous, at least approximately stepless measuring transducer.
  • the control device is therefore a stepless lift signal. Together with the continuously measured This allows the weight of the load to be used exactly at the permitted lifting height at any time. unnecessary Security reserves, such as those based on the tabular value of the usual load diagram can be avoided.
  • the task regarding the vehicle speed control is according to the invention solved in that the control device is connected to a lifting height sensor, which generates a signal dependent on the lifting height of the load handler and that the control device is designed such that the maximum Driving speed of the industrial truck is limited to a reduced value, if the lifting height of the load handler exceeds a limit height. in this connection is automatically ensured by the control device that if that Load handler exceeds the limit height, only with reduced Speed can be driven. This makes the regulation automatic complied with, according to which most industrial truck types only with a reduced load a speed exceeding a positioning speed allowed to.
  • the limit height is between 0.1 and 1.3 meters.
  • the limit height defines the lifting height of the load handler from which the Load suspension equipment is considered to be raised and thus a speed reduction positioning speed is required.
  • the Lifting height sensor is formed by a position switch.
  • the position switch can a simple switch located in the area of the mast be educated.
  • lifting height sensor is operated by one is formed at least approximately continuously working transmitter.
  • the figure shows a reach truck as an industrial truck according to the invention.
  • the Reach truck has a telescopically arranged in front of a driver's seat 1 extendable mast 2 on which a load suspension device designed as a load fork 3 can be moved up and down.
  • a reach truck is a Industrial truck in which driving is only permitted with a lowered load. This means that with the load picked up only at normal driving speed may be driven if the load does not exceed a limit height between 0.1 and 1.3 m is raised. However, if the load is raised higher than this value, may only be driven at positioning speed.
  • the Positioning speed is compared to the normal driving speed slows down and is opposite, for example, to align the reach truck one shelf is sufficient, but not for covering long distances.
  • a lifting height sensor 4 is provided in the area of the mast 2, with which it is determined whether the load suspension device 3 is deemed to be lowered, that is, at most is raised to a limit height between 0.1 and 1.3 m.
  • the signal of the Lifting height sensor 4 is in a control device 6 of the reach truck evaluated.
  • the control device 6 controls, among other things, the travel drive of the Reach truck and automatically ensures when the load handler 3 is raised a reduction of the maximum driving speed to positioning speed.
  • the Output signal is also supplied to the control device 6.
  • the Lifting height sensor 4 is at least approximately the lifting height for this function infinitely variable sensor.
  • the control device the measured values for the load weight and the lifting height continuously with those in the Control device for the respective type of industrial truck stored, just yet permissible pairs of values for lifting height and load weight compared. If the Operator tries to increase the lifting height allowed for the currently raised load exceed, the control device 6 intervenes automatically and prevents another Lifting the load handler 3. The same thing happens when an attempt is made Lift load exceeding the maximum capacity of the reach truck. This ensures that neither the maximum load capacity of the reach truck, the permissible load weight reduced with increasing lifting height was exceeded can be.
