However, the larger the diameter of a caster wheel, the higher the caster support arm must be. Either the base of a low-hanging object must be lifted higher above the wheels, or the casters must hang out to the sides straddling the low-hanging supported object. While rotating around the vertical shaft, swivel caster wheels sweep out a space.
Most modern roller coasters typically have pairs of wheels in each orientation, with 6 wheels per assembly, but this can vary by ride. The up-stop system was developed in 1919 by John A. Miller . He patented a design to make Pleasure-Railway attractions safer.
Riding a caster board requires using a twisting motion of hips and legs. A rider or "caster boarder" gains speed because each wheel is mounted on a 30° slant on the bottom of each deck. When each deck is pushed to the side, it causes the board to be pushed upward by the wheels' rotation against the gradient of the mounts.
It is sometimes called the Swedish wheel or Ilon wheel after its inventor, Bengt Erland Ilon (1923–2008), [1] who conceived of the concept while working as an engineer with the Swedish company Mecanum AB, and patented it in the United States on November 13, 1972. [2] It consists of a series of rubberized external rollers set at a 45° angle ...
1925 Robey tandem roller #42693, now owned by the Robey Trust [9]. The majority of rollers were of the same basic 3-roll configuration, gear-driven, with two large smooth wheels (rolls) at the back and a single wide roll at the front (in actuality, the wide roll usually consisted of two narrower rolls on the same axle, to make steering easier).
Caster angle and trail both influence the steering, albeit in different ways: caster tends to add damping, while trail adds "feel" and returnability. The caster wheel on shopping carts are an extreme case – the system is undamped but stable, as the wheel oscillates around the "correct" path. The construction has relatively high trail, but no ...
