Safety starts with the frame. GapVax puts it's unitized tank low to the ground and between the chassis frame to keep you from tipping. The hose reel is mounted on the same dual frame rails, which extend far beyond the engine to improve the strength of the reel, keep the operator away from the cab, and extend the life of the bearing. The boom is rotated by a worm gear instead of a hydraulic cylinder, and the boom is lifted by two cylinders to minimize stress and maximize strength.
