Retriever is powered by the truck™s air system, not hydraulics. Maintenance costs are reduced, cold weather delays and environmental spills eliminated and payload capacity increased, allowing larger loads to be hauled by smaller trucks. The patented curved deck creates the industry™s lowest loading angle (10º- 14º). Retriever™s exclusive No Idle System permits 30,000 lbs. to be loaded/unloaded with the truck™s engine off. The automatic three-position deck can be extended to add four feet of deck length. The LoRider deck option gets larger equipment under more road obstructions. Models range from 7.5 to 18 Tons.
