A support assembly attached to a vehicle 10 for carrying at least one elongate construction component, such as a utility pole, comprises front 31 and rear 75. The supports are attached to the side of the vehicle and at least one of them can be moved from a deployed to a retracted position to minimise the width of the vehicle. At least one of the supports may be detached from the vehicle. The front support may be attached to a loader arm of the vehicle, such as a shovel. The rear support may be attached to a stabilising leg 60 of the vehicle. The supports may be deployed with a sliding motion and may be adjustable to support different size components. At least one of the supports includes a restraint such as a strap, rope or chain to minimise movement of the components. The vehicle may be a backhoe loader.
