| 摘要 | A dolly system is disclosed, which overcomes drawbacks related to unwanted noise and jerks of prior art dolly systems. The dolly system comprises wheel assemblies (130) that have independently rotating lateral support wheels (132, 133) in combination with a center wheel (131) that interact with a continuous resilient element (122) when rolling along a rail track, without encountering any gaps or bumps and without producing squeal noise due to so-called wheel-climbing that may occur in curves along the rail track. | ||||||
