Abstract

PROBLEM TO BE SOLVED: To improve safety of work by eliminating erroneous operation of an operating lever of a plural number of winch drums. SOLUTION: A knob of an operating lever 12 of a third drum and a brake pedal 15 for the third drum are colored in the same color, for example, in yellow, a knob of an operating lever 13 for a main winding drum and a brake pedal 16 for the main winding drum are colored in the same color, for example, in red, and a knob of an operating lever 14 for an auxiliary winding drum and a brake pedal 17 for the auxiliary winding drum are colored in the same color, for example, in green.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a construction machine such as a crane or a pile driver.

[0002]

2. Description of the Related Art This type of construction machine has a plurality of winch drums such as a main winding drum, an auxiliary winding drum, a third drum, etc., and in order to prevent misoperation of the brake pedal when operating these winch drums. , Each brake pedal is colored with a different color.

[0003]

However, the operating lever of each winch drum is apt to be mistaken to some extent by indicating what lever is operated, and in particular, the operating lever and the brake pedal are disposed at different positions. The differences were even more pronounced. Also, it was difficult for anyone other than the driver to understand the position of the operation lever.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a construction machine which eliminates erroneous operation of the operation lever and improves work safety.

[0005]

In order to achieve the above-mentioned object, the present invention has a plurality of winch drums, the operating levers and the brake pedals of each winch drum are arranged in the driver's seat, and each brake pedal is provided. Is colored with a different color, the operating lever is colored with the same color corresponding to the brake pedal.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below based on embodiments shown in the drawings.

A crane 1, which is a kind of construction machine, has a boom 4 on an upper revolving structure 3 provided on a lower traveling structure 2 so as to be rotatable.
The boom hoisting winch drum 5, the third winch drum 6, the main winding winch drum 7, and the auxiliary winding winch drum 8 are mounted.

In addition, on the operation stand 10 in the driver's seat 9,
A boom raising / lowering winch drum operating lever 11, a third winch drum operating lever 12, a main winding winch drum operating lever 13, and a supplementary winding winch drum operating lever 14 are arranged, and a third winch drum brake pedal 15, a main winch drum brake pedal 15, A winding winch drum brake pedal 16 and an auxiliary winding winch drum brake pedal 17 are provided.

Then, a knob colored yellow, for example, is attached to the third winch drum operating lever 12, and the third winch drum brake pedal 15 is covered with a yellow rubber cover to be colored in the same color. The knob of the drum operating lever 13 and the main winding winch drum brake pedal 16 are colored in the same color, for example, red in the same manner as above, and the auxiliary winding winch drum operating lever 1
The knob 4 and the auxiliary winding winch drum brake pedal 17 are colored in the same color, for example, green.

With such a configuration, the driver can operate the operation lever and the brake pedal colored in the same color, so that the driver can determine at a glance which operation lever and the brake pedal to operate, and the erroneous operation can be performed. Can be prevented.
In addition, when the window of the driver's seat 9 is large, it is possible for a worker other than the driver's seat 9 to recognize which winch drum the driver is trying to operate, and the work safety can be improved.

It should be noted that if the knobs of the operating levers are so large that the driver does not hide them even if they are held by the hand, the knobs can be viewed even if the driver holds the knobs. If it is colored, it will be easier to confirm and safer.

[0012]

As described above, in the construction machine of the present invention, the operating lever and the brake pedal for operating the plurality of winch drums are colored in the same color for each winch drum, so that the driver is the same. It is enough to operate the colored operation lever and brake pedal, so you can determine at a glance which operation lever and brake pedal to operate,
Erroneous operation can be prevented. In addition, when the window of the driver's seat is large, it is possible for a worker other than the driver's seat to recognize which winch drum the driver is trying to operate, thereby improving work safety.
