Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device for displaying an allowable load of a cargo handling device mounted on a forklift truck or the like.

[0002]

2. Description of the Related Art Conventionally, in a forklift truck, a cargo handling device is mounted on a front portion of a vehicle body. An allowable load table indicating the weight of luggage that can be lifted by the device is attached to the front of the driver's seat, and the worker performs loading and unloading work with reference to the allowable load table.

[0003]

Conventionally, the allowable load table is as follows.
Forklift truck specifications, such as the type of vehicle, the mast height and mast inclination of the cargo handling equipment, the type of attachment used, and the type of tires used in the vehicle, differ depending on the type of forklift truck. ing. For this reason, inventory management of the permissible load table is troublesome, and at the time of assembling a forklift truck, there has been a problem that the workability of attaching the permissible load table is poor.
An object of the present invention is to solve these problems.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a switching operation unit for switching numbers to output necessary load data of a cargo handling device, and the switching operation unit. A processing unit for detecting the switching number, and searching for the data of the allowable load corresponding to the switching number from the data group of the allowable load stored therein, and outputting the data, and the data output from the processing unit. And a display unit for displaying the allowable load.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, a permissible load display device for displaying permissible load of a forklift truck is a switching operation unit for switching a number in order to output data of permissible load of a required cargo handling device. A processing unit 2 for detecting a switching number of the switching operation unit 1 and searching for an allowable load data corresponding to the switching number from a group of allowable loads stored therein, and outputting the data; The display unit 3 is configured to display data output from the processing unit 2. The switching operation unit 1 is a dial-type switching device provided in the front part of the driver's seat, and turns a knob to a required number in the displayed number. The processing device unit 2 is provided inside the vehicle body, and has a CPU (central processing unit) 4 and a ROM (storage device) 5 inside. RO
M5 stores a plurality of allowable load data that vary depending on the mast height of the cargo handling device, the mast inclination angle, the type of tire used, and the like. , The mast inclination angle, the type of tire to be used, and the allowable load in this specification are stored and numbered. The display unit 3 is provided at the front of the driver's seat and is of a cathode ray tube type or a liquid crystal display type.

The operation of such a configuration will be described. First, the operator performing the assembly switches the switching operation unit 1 to a number that matches the specification of the forklift truck. When the worker performs the cargo handling operation, the CPU 4 in the processing unit 2 detects the switching number of the switching operation unit 1 and matches the switching number from the allowable load data group stored in the ROM 5 in the processing unit 2. Search and output data of allowable load. Then, the display unit 3 displays the data of the allowable load output from the processing unit 2.

In this embodiment, numerical values are displayed on the display unit 3, but they may be displayed as graphs in the same manner as in the prior art.

In addition, in the forklift truck equipped with the allowable load display device of the present invention, the ROM 5 in the processing unit 2 may be replaced when the attachment or the like is changed. ROM5
Is detected, and the number of numbers displayed on the switching operation unit 1 is changed to a number corresponding to the data number of the allowable load stored in the replaced ROM 5.

[0009]

The present invention relates to a switching operation unit 1 for switching a number of an allowable load display device of a forklift truck so as to output necessary load data of a loading device.
A processing unit 2 that detects a switching number of the switching operation unit 1 and searches for data of an allowable load corresponding to the switching number from a data group of allowable loads stored therein, and outputs the data. The display unit 3 configured to display the data output from the processing unit 2 allows the data of the allowable load to be collectively stored in the ROM 5 in the processing unit 2. As a result, even if the specifications of the forklift truck are diversified and the number of types is enormous, the type of the ROM 5 for storing the allowable load data may be small and easy to manage. The operation of displaying the allowable load can be easily performed. In addition, if the specification change of the forklift truck, such as the change of the cargo handling device, is within the range of the specification stored in the ROM 5, the data of the allowable load can be displayed by simply changing the number to the predetermined number by the switching operation unit 1. And the work becomes easier.
