A mitigating body 7, a display unit 26 that can detect the load 12 of the cargo 2 detected by the load cell 5, and a connection box 23 through which a detection output signal transmitted from the load cell 5 to the display unit 26 passes, The display unit 26 includes a measuring device 24 for digitally displaying the load 12 and a printer device 25 for printing. The display unit 26 confirms (by an operator) such as the front of the driver's seat 16 of the vehicle body 1. It is provided at a position where it is easy to do.

Specifically, 5 ... are four load cells, has a detection projection 6 to charge the contact portion 3a of the platform 3 of the lowered position from the bottom side, the loading portion 20 side of the vehicle body frame 22 It is provided to.
As shown in FIG. 6, the impact relaxation body 7 includes a fixing portion 17 fixed to the frame 22, a pressing body 18 that presses the detection protrusion 6 of the load cell 5 from above, and a fixing portion 17. cushion and is attached to the opening 17a Lube Mesh member 15 to hold the pushing member 18 vertically movably, the contact portion 3a of the platform 3 the upper part of the lowered position is secured by bolts or the like of the pressing member 18 abuts the The material 8 is provided.

As shown in FIG. 7, the pallet loader 10 includes a totaling calculation means 28 for summing up and summing up the load 12 of the cargo 2... Repeatedly loaded by a numerical value sent from the measuring device 24 of the loaded load measuring means 4; An allowable load amount input means 29 for inputting nine allowable load amounts, a comparison calculation means 30 for comparing the allowable load amount with the total load accumulated by the total calculation means 28, and an output signal from the comparison calculation means 30 And a tolerance display means 31 for displaying the allowable load that can be further mounted on the aircraft 9 and a reset means 32 for resetting the numerical values calculated by the total calculation means 28 when the installation on the aircraft 9 is completed. . The above 28 and 30 are composed of electronic circuits of a computer (personal computer), and 31 is composed of a display of a personal computer.
The allowable loading amount input means 29 and the tolerance display means 31 are provided at a position where the operator can easily confirm and operate (not shown) such as in front of the driver seat 16 of the vehicle body 1.

Next, a method of using the above pallet loader 10 will be described.
As shown in FIGS. 2A and 3A, the platform 3 is lowered and received on the load load measuring means 4.
In advance, the measurement device 24 and the printer device 25 of the display unit 26 are set to zero (reset) in a state where the unloaded platform 3 is lowered to the lowest limit and received by the load cell 5.

Then, when the cargo 2 is loaded on the platform 3, as shown in FIG. 6, the contact portion 3 a of the platform 3 presses the cushion material 8 of the impact relaxation body 7 from above, and the pressing body 18 of the load cell 5. The detection projection 6 is pressed to detect the load 12 of the cargo 2 and is displayed on the display unit 26 of the loaded load measuring means 4.
It is also possible to check the load 12 of the cargo 2 with the measuring device 24 of the display unit 26 when the cargo 2 is loaded or while the cargo 2 is being transported with the pallet loader 10 and to print the numerical value with the printer device 25. It is.

  Since the pallet loader 10 travels on a flat paved road surface such as an airport warehouse floor or a runway (as described above), the platform 3 has less vertical vibration and more than twice the measured rated capacity. By using a standard load cell 5 that can withstand overload, the load cell 5 may be damaged even if the pallet loader 10 is run in a measurable state (the platform 3 loaded with the cargo 2 is lowered to the lowest limit). There is no.

Then, as shown in FIG. 4, the pallet loader 10 is placed next to a vehicle 21 such as a truck or a dolly, and the platform 3 loaded with the cargo 2 is lifted as shown in FIGS. 2 (b) and 3 (b). The cargo 2 is transferred to the vehicle 21. Then, loading work of the cargo 2 from the vehicle 21 to the aircraft 9 is performed.
Alternatively, although not shown in the figure, the cargo 2... May be transported to the aircraft 9 by the pallet loader 10 and the platform 3 may be lifted so that the aircraft 9 can be loaded (directly) on the aircraft 9. If this is the case, it is possible to save the trouble of reloading the cargo 2 onto the vehicle 21 such as a truck or a dolly, shorten the working time, and increase the working efficiency.

Then, again, the operation of lowering the platform 3 and loading and transporting the cargo 2 as shown in FIGS. 2A and 3A is repeated.
At this time, in FIG. 5 and FIG. 7, the allowable load amount of the aircraft 9 is input to the allowable load amount input means 29, and the value of the load 12 (see FIGS. 2 and 3) for one transport is calculated. A signal is transmitted from the measuring device 24 to the total calculation means 28 as indicated by an arrow 33, and the comparison calculation means 30 compares this total load with the allowable load amount (of the aircraft 9), and a tolerance display means 31. Displays the allowable load of the cargo 2 that can be further mounted on the aircraft 9.

Here, the transportation operation of the cargo 2 is performed while confirming that the total amount of the loads 12 of the cargo 2 transported by the pallet loader 10 does not exceed the allowable load.
When the transportation of the cargo 2 mounted on a certain aircraft 9 is completed, the reset means 32 resets the numerical values calculated by the totaling calculation means 28 so that the pallet loader 10 of the cargo 2 mounted on another aircraft 9 is reset. Make the load 12 ready for aggregation.

  As described above, the pallet loader 10 according to the present invention is a pallet loader having the platform 3 that can be moved up and down on the vehicle body 1, and includes the load load measuring means 4 that measures the load 12 of the cargo 2 loaded on the platform 3. Because it is equipped, it is not necessary to load the load 2 on the load measuring device prepared separately, and the load 12 can be measured at the same time as the transfer of the load 2, so the labor and time of load measurement and load transfer can be saved. , Work efficiency can be improved.

The load load measuring means 4 includes a plurality of load cells 5 provided on the vehicle body 1 side for receiving the lowered platform 3, and a display unit 26 for displaying the load 12 measured by the load cell 5. Therefore, the load 12 of the cargo 2 can be easily measured simply by lowering the platform 3.
As described above, since the measurement can be easily performed simultaneously with the transportation operation of the cargo 2, the operation time can be shortened and it is convenient.

  Further, since the impact relaxation body 7 is attached between the detection projection 6 of the load cell 5 and the contact portion 3a of the platform 3, the detection projection 6 of the load cell 5 is not moved when the platform 3 is lowered. The impact received from the contact portion 3a of the platform 3 can be reduced, and the load cell 5 can be prevented from being damaged.

The pallet loader 10 according to the present invention is a pallet loader having a platform 3 on which a cargo 2 to be loaded on an aircraft 9 is loaded so that the vehicle main body 1 can be lifted and lowered. The load 12 of the cargo 2 loaded on the platform 3 Loading load measuring means 4 for measuring, totaling calculating means 28 for totalizing and summing the load 12 of the repeatedly loaded cargo 2 by the numerical value sent from the loading load measuring means 4, and the allowable loading amount for inputting the allowable loading amount of the aircraft 9 The input means 29, the comparison calculation means 30 for comparing the allowable load amount and the total load accumulated by the total calculation means 28, and the allowable load that can be further mounted on the aircraft 9 by the output signal from the comparison calculation means 30 And a tolerance display means 31 for displaying, it is not necessary to transfer the cargo 2 to a load measuring device prepared separately, and the load 12 can be measured simultaneously with the transportation of the cargo 2. Since it is, can be omitted transshipment of labor and time of the load measuring and cargo 2, it is possible to increase the working efficiency.
In addition, since the operator can easily confirm how much cargo 2 can be loaded on the aircraft 9, there is no risk of carrying the aircraft 9 beyond the allowable loading capacity, and the structure is simple. Nevertheless, work efficiency is improved and it is convenient.
