Abstract: A double hollow rod cylinder is provided. The cylinder includes a cylinder body and a piston apparatus. The cylinder body has a hollow cylinder member with an internal cylinder cavity. The piston apparatus includes a piston, a first piston rod coupled to a first end of the piston and a second piston rod coupled to the second end of the piston. The piston apparatus is arranged such that the piston is within the cylinder cavity. The piston is fixed in place while the cylinder body is free to slide from a first position to a second position based on fluid input to the apparatus. A fluid system provides fluid to the first piston rod to move the cylinder body towards the free end of the first piston rod and fluid to the second piston rod to move the cylinder body towards the free end of the second piston rod.
