The independent wheel suspension system (100) of the present invention provides an optimal shock absorption in which the shock absorbent device (30 ) is easily activated by the weight of the user to provide for an improved maneuverability of the movable structure (B). The system (100) includes a truck (10) for mounting on the movable structure (B), a swing arm (12) pivotally connected to the truck (10) for rotation around a horizontal axis (H) between first and second limit positions, at least one wheel (14) rotatable on said swing arm (12), a shock absorbent device (30) with a shock absorber (34) and a guide (33), and a user accessible tension adjuster (35) for adjusting the tension of the shock absorber (34) in accordance with the desired stiffness for use or preference. The guide (33) has a first end (36) pivotally connected to the truck (10). The shock absorber (34) is mounted coaxially on the guide (33) and has opposite ends abutting the swing arm (12 ) and a free second end (38) of the guide (33) respectively, whereby the shock absorbent device (30) can freely follow rotation of the swing arm (12) betwe en the limit positions. This independent suspension system (100) can be optimal ly applied to any device mounted on roller(s), or wheel(s), that would benefit from such an adjustable independent suspension system.
