Suspension is the term given to the system of springs, shock absorbers and linkages that connects a vehicle to its wheels. Suspension systems serve a dual purpose — contributing to the vehicle's road handling and braking for good active safety and driving pleasure, and keeping vehicle occupants comfortable and reasonably well isolated from road noise, …

Vibro compaction

A vibrator hung from a crane is lowered into the ground with penetration usually helped by water jetting. The energy from the vibration reduces the inter-granular forces between the soil particles, making them denser as the vibrator is raised in lifts. Sand backfill is then poured in from ground level to compensate for any decrease in soil volumes.
