摘要： A tandem wheeled carriage of heavy, very strong steel construction capable of lifting 5 to 30 or more tons of load and transporting the same over difficult roadways, wherein a laterally spaced pair of lift devices is provided on the carriage and adapted to be connected to laterally spaced supporting beams of the load, wherein each lift device is operable independently of the other to selectively lift or lower either or both sides of the load to avoid obstacles, and wherein a steering mechanism is provided to synchronously pivot all wheels of the tandem thru a steering angle whereby the rear of the load can be steered straight ahead or also in lateral directions to avoid obstacles and to allow maneuvering of a long load around corners which are too sharp for conventional transport devices.
摘要翻译：一种重型，非常强的钢结构的串联轮式托架，能够提升5至30吨或更多吨的载荷并在困难的道路上运输，其中横向间隔开的一对提升装置设置在托架上并适于连接到侧面负载的间隔的支撑梁，其中每个提升装置可独立于另一个而起作用以选择性地提升或降低负载的任一侧或两侧以避免障碍物，并且其中提供转向机构以同步地枢转所述串联的所有车轮，转向角度，由此负载的后部可以直线前进或横向方向转向，以避免障碍物并允许围绕传统运输装置太尖锐的拐角处的长负载的操纵。

摘要： A tractor tire is disclosed having widely spaced lug pairs with a symmetrical Y-shaped footprint, each lug pair having inclined transverse lugs and an elongated longitudinal nose portion at the peripheral centerline providing a central lug projecting in the direction of tire rotation and overlapping the trailing end portions of the next adjacent lug pair. The unique lug arrangement minimizes vibration to improve safety during operation on the highway while retaining the characteristics required for effective off-the-road (OTR) performance on soft ground.
摘要翻译：公开了一种具有对称的Y形足迹的具有宽间隔的凸耳对的牵引轮，每个凸耳对具有倾斜的横向凸耳，并且在周边中心线处具有细长的纵向鼻部，提供沿轮胎旋转方向突出的中心凸耳，下一个相邻凸耳对的端部。独特的凸耳装置使振动最小化，从而提高了高速公路运行时的安全性，同时保持了在软土地上实现有效的越野（OTR）性能所需的特性。
