This invention relates to the driver's cab of construction machinery, which is protected by a head guard.
この種の建設機械の運転室を第１図を参照して
説明する。この図示の建設機械は、トラツク２上
に旋回体１を旋回可能に装備したものである。 The driver's cab of this type of construction machine will be explained with reference to FIG. The illustrated construction machine has a revolving body 1 mounted on a truck 2 so as to be rotatable.
しかして、この種の建設機械の運転室において
は、運転室４は建設機械本体、すなわち旋回体１
の運転室取付台３に独立にかつ着脱可能に設置さ
れ、ヘツドガード５は同じく運転室取付台３に運
転室４と別個に複数本の支柱９で、運転室４を主

４に覆い被さるようにかつ着脱可能に取付けられ
ている。このように、運転室４とヘツドガード５
とが別個に運転室取付台３に着脱可能に取付けら
れているのは下記の理由による。 Therefore, in the operator's cab of this type of construction machine, the operator's cab 4 is the main body of the construction machine, that is, the revolving body 1.
The head guard 5 is installed independently and removably on the driver's cab mount 3 of the driver's cab, and the head guard 5 is installed separately from the driver's cab 4 on the driver's cab mount 3 with a plurality of supports 9 to protect the driver's cab 4 mainly from falling objects from above. It is detachably attached to cover the driver's cab 4 for protection. In this way, the driver's cab 4 and head guard 5
The reason why these are separately and removably attached to the driver's cab mounting base 3 is as follows.
(1) ヘツドガード５を取付ける場合も取付けない
場合も標準の運転室４を共通に使うため。(1) The standard operator's cab 4 is commonly used whether or not the head guard 5 is installed.
(2) 支柱９を有しないヘツドガード５を運転室４
の上面に取付けた場合、運転室４自体がヘツド
ガード５の受ける衝撃的な荷重を直接的に受け
るために、運転室４を構成する壁や柱などの部
材の強度を高めなくてはならず、前記部材の断
面寸法が大きくなりその分運転室４の外形寸法
や重量が増し、運転室取付台３はもちろん建設
機械全体に悪影響を及ぼす。(2) The head guard 5 without the pillar 9 is attached to the driver's cab 4.
When mounted on the top surface, the driver's cab 4 itself directly receives the impact load received by the head guard 5, so the strength of the members such as walls and pillars that make up the driver's cab 4 must be increased. As the cross-sectional dimensions of the members increase, the external dimensions and weight of the driver's cab 4 increase accordingly, which adversely affects not only the driver's cab mount 3 but also the construction machine as a whole.
(3) ヘツドガード５は必ずしも取付けられるもの
ではなく、建設機械の使用場所により取付ける
か否かが決められるものである。(3) The head guard 5 is not necessarily installed, and whether it is installed or not is determined depending on the location where the construction machine is used.
しかしながら、上述の従来の建設機械の運転室

あるなどの問題点がある。 However, the driver's cab of the conventional construction machine described above has a driver's cab 4 and a head guard 5 mounted on the driver's cab mounting base 3.
Since both the driver's cab 4 and the head guard 5 are simply attached separately, it is necessary to align them individually when attaching both the driver's cab 4 and the head guard 5 to the driver's cab mount 3, making the installation work complicated. Further, when disassembling and transporting the vehicle, the two are lifted up individually and the operator's cab 4 and the head guard 5 are placed in separate spaces for transport, so there is a problem that a large transport space is required.
