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： 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.
