Abstract
A cartridge for storing pipe lengths on a horizontal directional drill that allows easy loading and unloading of pipes from the cartridge while it is attached to the drill. Longitudinal support members and towers at each end of the cartridge provide structural support to the cartridge and maintain the pipe lengths within the cartridge. The sides of the cartridge are open and unobstructed. Loading and unloading of pipes can, therefore, be done through the sides of the cartridge.
