The "A" Frame Bottom Loader is recommended for servicing both sides of the platform and for adjacent arm crossover. The secondary arm is available as a rigid pipe or hose. The advantage for this arm model is short range truck bottom loading applications. Also, if parking is a concern, due to its ROM, it parks at a high angle, allowing arm to store in a high and skinny parking window. Arms feature the D2000 World Series swivel joints for ultra low maintenance and the easy to adjust spring cylinder balance.
