Dual wheel swivel caster with a torque limiter and associated method

A dual wheel swivel caster includes a swivel assembly, a horn, a rig hub, a solid axle, at least one ring of roller bearings, first and second wheel assemblies, and at least one ring of bearings. The first wheel assembly has a first wheel axis, and includes an annular plate element. The torque limiter is configured to rotatably couple the first and second wheel assemblies with the solid axle when the torque between the annular plate element and the torque limiter is below a preset value. The torque limiter is configured to rotatably decouple the first wheel assembly from the solid axle and the second wheel assembly when the torque exceeds the preset value. The ring of bearings is configured to allow the first wheel assembly to rotate independently of the solid axle and the second wheel assembly about the rotational axis when the torque exceeds the preset value.
