• and
• b) a derrick mast comprising:
• a lower mast section with a base end and an upper end, the base end pivotally attached to the frame;
• and
• an upper mast section pivotally attached to the upper end of the lower mast section,
• the derrick mast configured to move between a lowered position and a raised substantially vertical position relative to the frame, wherein in the lowered position, the lower mast section extends along a plane substantially parallel to the horizontal plane of the frame and the lower mast section extends along a length of the frame on the first side and the upper mast section is folded along the second side, beside the lower mast section and extends in the plane in which the lower mast section extends, substantially parallel to the horizontal plane of the frame.
