| 摘要 |
The invention concerns a trailer (1) for transporting at least a four-wheel boat trailer, comprising an axle and two wheels (4, 5) bearing two parallel side members (2, 3) forming with two parallel front (6) and rear (7) crosspieces, the carrier-frame (8) of the trailer, extended at the front by a towbar (9), said frame bearing at least two parallel and longitudinal running surfaces (14, 15) spaced apart for receiving on one side the right wheels and on the other the left wheels of the four-wheel boat trailer. The invention is characterised in that at least one of the running surfaces crosses over a wheel (4) of the trailer (1) and comprises like the other strip (15) three successive running zones from the rear forwards: a planar zone (141) sloping from down upwards and from the rear forwards, a planar horizontal zone (142) above and on either side of the wheel (4) level and a planar zone (143) sloping from up downwards and from the rear forwards for blocking two wheels of the four-wheel boat trailer around the wheel (4)
