Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for handling oversized cargo using a forklift or a push-pull forklift.

[Conventional technology]

BACKGROUND ART Various cargo handling devices and carriers have been used to streamline operations such as loading and unloading, transporting, and storing cargo. For example, there are widely used methods of cargo handling using a regular forklift and wooden or steel pallets with insertion holes or skid-type pallets, and unit load systems using a push-pull forklift and sheet pallets. It is widespread.

According to the above-mentioned methods, the most efficient cargo handling method is to standardize the cargo. In actual cases, several types of stylized cargo are assumed in advance, and the shapes and dimensions of transportation equipment such as forklifts, attachments, and pallets are standardized to suit them.

In other words, the unit load system that defines the basic dimensions for efficient transportation of the cargo mentioned above is not only established in the JIS standard, but also in the 15O (International Organization for Standardization) standard, and the dimensions are 1140 x 1140 mm, - Type 11 (110l) is a type of JIS standard for flat pallets for transport.
It is standardized to fit 100x1100.

Therefore, at present, although cargo handling operations for standardized cargo can be carried out very effectively, it is virtually impossible to carry out cargo handling operations for non-standard oversized cargoes.

In addition, when attempting to handle such non-standard oversized cargo even temporarily, it is necessary to prepare a special wooden pallet or replace the forklift attachment, which requires complicated labor and time. Various wooden pallets, attachments, etc. must be prepared and stored, resulting in a great deal of waste in equipment costs and pallet storage and management.

[Problem that the invention seeks to solve]

The present invention has been made to solve the above-mentioned problems, and provides a method for smoothly handling, transporting, and moving non-standard oversized cargo.

[Means for solving problems]

The present invention provides for a forklift with a depth within a range of ±200 mm from the tip of the existing fork or surface platen, and a frontage 1.1 to 20 times the maximum operating width of the existing fork or platen. This is a cargo handling method for oversized cargo, which is characterized by carrying out cargo handling work while placing a rigid plate having a seat retainer and fixing the rigid plate with a seat retainer.

The method of the present invention will be explained using the drawings.

Figure 1 (a) is a plan view of the main parts showing the mounting state of the rigid plate when using a push-pull forklift;
FIG. 1(b) is also an elevational view.

In Figure 1 (a) and (b), on the existing platen 1,
Depth within 200M from the tip 11 of the existing platen and 11 to 2.0 of the maximum operating width of the existing platen.
This shows an example of a rigid plate having double the frontage.The rigid plate 2 is placed on the rigid plate 2, and while the rigid plate 2 is fixed with the seat retainer 4, the cargo on the sheet pallet is unloaded using a conventional push-pull mechanism. This is the way to do it.

In other words, since the normal operating width of the existing platen is in the range of a minimum of 900 mx to a maximum of 1100 mx, by expanding the width of the rigid plate to a range of approximately 1200 mx to 2200 mx, the width (frontage) of the cargo loading bottom can be reduced. The existing 1100m+++ will be expanded to 2200mx.

Examples of the material for the rigid plate include metal plates such as stainless steel and plated steel plates, resin plates such as FRP plates and ultra-high molecular weight polyethylene plates, and wooden plates such as plywood and plywood. Among these, metal plates are particularly preferred.

Further, in order to carry out cargo handling operations smoothly, it is preferable to arrange a plurality of strip-like protrusions 5 in parallel in the depth direction on the upper surface of the plate, as shown in FIG.

Furthermore, in order to improve the function of the rigid plate, the rigid plate is tapered from the base to the tip, and the thickness of the tip is in the range of 1 to 5 mm, and the back surface of the rigid plate is By providing a supporter (supporting piece) 6 that can be attached to the existing fork or the existing platen, safety during work can be improved.

A stopper 3 is provided on the rigid plate as necessary,
It is preferable to prevent forward sliding when sliding the load on the rigid plate.

In addition to the above, these stoppers 3 include screws,
This may be done by any known method such as fitting or welding.

The size of the rigid plate is such that the distance between the tip 11 of the existing fork or platen and the tip 12 of the rigid plate 2 is in the range of ±200B1, preferably ±150B,
The width is 1 of the maximum operating width of the existing fork or platen.
．． It is in the range of 1 to 20 times, preferably in the range of 12 to 1.5 times.

If the depth extends beyond 200B from the tip of the existing fork or platen, cargo handling operations such as picking up and placing cargo will not be carried out smoothly.

Moreover, the stability of the cargo cannot be expected from the tip of the existing fork or platen, and smooth cargo handling operations cannot be performed.

On the other hand, if the width of the rigid plate exceeds twice the maximum operating width of the existing fork or platen, loading of oversized cargo will not be carried out smoothly (this is not desirable as it may cause safety problems). 0 The cargo handling method of the present invention will be further explained below with reference to the drawings.

As shown in Figure 1 (a) and (b) above, the existing platen 1
A rigid plate 2 is placed on top and held and fixed with a seat retainer 4. In this case, it is preferable to align the center line of the existing platen with the center line of the plate for the upper cargo loading balance. It also handles cargo on sheet pallets.

In other words, with the rigid plate fixed with a seat retainer at points (a) and (b) in FIG.
Insert the button under the tab in Figure 5 (a) to push the face plate 22 to the leading edge), and then
3, grip the tab of the sheet pallet 21 (5th
Figure (b)). Then, while gently pulling the face plate 22 forward (FIG. 5(c)), the cargo is placed on the platen and handled.

At this time, if you want to leave the sheet pallet on the platen and load only the cargo onto a freight car, truck, etc., you can release the sheet retainer once and fix the sorting pallet and rigid plate at the same time. At this time, if the rigid plate and the existing platen are temporarily attached using the stopper 3, cargo handling can be carried out more smoothly.

〔Effect of the invention〕

As described above, according to the method of the present invention, by attaching a rigid plate of a specific size to a conventional forklift, the attachment of the conventional forklift can be used as is and can be easily removed, thereby eliminating the need for complicated replacements. It is easy to use, the equipment cost is low, and it is possible to handle oversized cargo or multiple cargoes in an integrated manner without changing conventional operations, and cargo handling efficiency can be greatly improved.
