音シートを着けたままの移動は作業車の車輪が防
音シートを踏むなどして防音シートを破損するこ
とがあつた。 However, in the past, when moving a work vehicle a short distance at a work site, the soundproofing sheet was either removed each time, or the soundproofing sheet was moved while the sheet was on.Removing the soundproofing sheet each time required a great deal of labor and work. Efficiency was reduced, and if the soundproofing sheet was moved while the sheet was on, the wheels of the work vehicle could step on the sheeting and damage it.

音シートを破損する虞のない低騒音作業車を提供
することを目的とするものである。 The present invention was developed in view of the above circumstances, and involves inserting cables along the lower edge of the soundproof sheet and pulling the cables up in conjunction with the expansion and contraction of outriggers that support the body of the work vehicle during work. It is an object of the present invention to provide a low-noise working vehicle which can efficiently move short distances at a work site by being lowered, and which is free from the risk of damaging the soundproof sheet during movement.
以下、図面により本考案の実施例について説明

ることができる。 A flexible sound insulating sheet 11 having sound insulating properties is provided around the entire side surface of the vehicle body 1 excluding the rear outriggers 4 and 6.
However, it is installed so that its lower end reaches the ground. In front of the driver's cab 2, there is provided an intake duct 12 surrounded by a soundproof sheet and having an opening facing upward.
An exhaust hole 18 is provided on the upper surface of the vehicle body behind the driver's cab 2. Soundproof sheet 11 and intake duct 12
can be removed and stored in the vehicle when the vehicle is in motion.
車体１の左右面及び前面に位置する防音シート

トリガ６のベース１０に固着されている。 A cable insertion portion is formed at the lower end of the soundproof sheet 11 located on the left and right sides and the front of the vehicle body 1, and one end of the rope 13, which is the cable, is fixed 14 to the base 8 of the left rear outrigger 4. The other end of the rope 13 passes through the insertion part of the soundproof sheet 11 on the left side of the vehicle body 1 and is fixed to the base 7 of the left front outrigger 3.
5, passes through the lower end of the soundproof sheet on the front of the vehicle body 1, is fixed 16 to the base 9 of the right front outrigger 5, and is fixed to the base 10 of the right rear outrigger 6 through the insertion portion on the right side of the vehicle body 1. .

またアウトリガ３，４，５，６の格納により車体
１は車輪によつて支持されるので、作業車は移動
可能となる。 With the above configuration, outriggers 3, 4, 5, 6
When retracted and stored, both ends of the rope 13 are fixed to the bases 8, 10 of the rear outriggers 4, 6, and the middle part of the rope 13 is fixed to the bases 7, 9 of the front outriggers 3, 5. As shown in FIG. 3, the soundproof sheet 11 is pulled up by the rope 13, and the lower end of the soundproof sheet 11 is separated from the ground.
Moreover, since the vehicle body 1 is supported by the wheels by retracting the outriggers 3, 4, 5, and 6, the work vehicle becomes movable.
作業車の移動後、アウトリガ３，４，５，６を
再度伸長させれば、防音シート１１は下されて、
その下端が地面に接し、車体１はアウトリガ３，

及び作業能率の向上に多大な効果を有する。 As described above, the present invention covers the outer circumference of the body of a work vehicle equipped with an outrigger, such as a truck hoe, crane vehicle, or aerial work vehicle, with a flexible soundproof sheet so that the lower end of the soundproof sheet reaches the ground. In a low-noise work vehicle whose sides are sealed, cables are inserted into the soundproof sheet, and the cables are pulled up by the retracting action of the outriggers to lift the soundproof sheet. Since the soundproof sheet is automatically raised and lowered when the work vehicle is moved, there is no need to remove and install the soundproof sheet every time the vehicle is moved, which is highly effective in preventing damage to the soundproof sheet and improving work efficiency. have
