Abstract: A cart wheel structure having a pair of wheels rotatably mounted to opposite ends of an axle rod. The axle rod is mounted to a base portion of a cart by a pair of fabricated brackets having an upstanding swivel post adapted to be received in swivel cavities provided on the cart base portion. The swivel cavities are adapted to receive the swivel post of conventional swivel caster whereby the cart may be provided with caster and non-caster wheels as desired. The cooperation between the axle rod and brackets provides an accurate maintained disposition of the wheels carried on the opposite distal ends of the axle rod.

Abstract translation: 一种车轮结构，其具有可旋转地安装在轴杆的相对端的一对车轮。 轴杆通过一对制造的支架安装到推车的基座部分，该支架具有直立的旋转柱，其适于容纳在设置在推车基座部分上的旋转空腔中。 旋转空腔适于接纳常规旋转脚轮的旋转柱，由此可以根据需要提供推土机和非脚轮。 轴杆和托架之间的配合提供了在轴杆的相对的远端上承载的轮的精确的维持配置。
