To provide a compaction vehicle with a high degree of reliability which makes it possible to surely restrict the travelling at the time of coming into contact with a guard fence of an obstacle.SOLUTION: A brake force of a negative brake 34 is exerted on front and rear hydraulic motors 7, 8, and the hydraulic oil from the charge pump 19 driven by an engine 17 is supplied to a brake release cylinder 34c of the negative brake 34 through a forced exhaust valve 39 at the communication position, and the brake force is released to enable the vehicle 1 to travel. Guard fences 40 and 41 that can swing to the front and rear of the vehicle 1 are provided and connected to the forced exhaust valve 39 via a wire cable 47 and a push rod 48, and the swing of the guard fences 40 and 41 due to contact with the obstacle is mechanically transferred to the forced exhaust valve 39 so as to switch the position to the drain position.SELECTED DRAWING: Figure 1

    【課題】障害物へのガード柵の接触時に確実に走行制限できる高い信頼性を備えた転圧車両を提供する。【解決手段】前部及び後部油圧モータ7,8にネガティブブレーキ34の制動力を作用させると共に、エンジン17により駆動されるチャージポンプ19からの作動油を連通位置の強制排出弁39を経てネガティブブレーキ34のブレーキ解除シリンダ34cに供給し、制動力を解除して車両1を走行可能とする。車両1の前後に揺動可能なガード柵40,41を設けてワイヤケーブル47及びプッシュロッド48を介して強制排出弁39と連結し、障害物への接触によるガード柵40,41の揺動を機械的に強制排出弁39に伝達してドレン位置に切り換える。【選択図】図1
