A frame roller 62 can be supported by the fifth roller support 60a and the sixth roller support 60b. 
As the hose is urged through the apparatus into the support structure, the rollers 34a, 34b, 34c, 34d, 61a, 61b, and 62 can guide the hose to ensure that no pitch points form. The rollers 34a, 34b, 34c, 34d, 61a, 61b, and 62 can also prevent contact of the hose with the frame 10, reducing friction wear of the hose.
The powered cylinders 50a and 50b can be connected with a power system. A motor 72 can be operatively connected with the power system.
The motor 72 can be a pneumatic motor, an electric motor, an internal combustion engine, a hydraulic motor, or the like. In one or more embodiments, a drive power system can be connected with the motor 72 instead of the power system. For example, if the motor 72 is an electric motor a power source and electric control panel can be operatively connected with the motor 72 to drive and control the motor 72. The electric control panel can be a variable speed drive controller. The connection of the motor and powering of the motor is known to one skilled in the art with the aid of this disclosure.
The motor 72 can drive the top drive roller 26, one or more of the lower drive rollers 42a and 42b, or combinations thereof.
In one or more embodiments, the top drive roller 26, one or more of the lower drive rollers 42a and 42b, or combinations thereof can be an idler roller as long as at least one of the drive rollers 26, 42a, and 42b is powered by the motor 72.
FIG. 2 depicts a hose being retrieved into a support structure.
The support structure 25 can be a trailer, a vehicle, a crate, a building, a skid, or the like.
The apparatus 2 can be connected with the support structure 25. To start retrieving the hose with the apparatus 2, a proximate end 200 of the hose 22 can be placed onto at least a portion of the lower drive rollers 42a and 42b.
