A sliding spider ( 10 ) for supporting tubing (T) through a rig floor includes a fixed gate ( 60 ) and a movable body ( 30 ). The fixed gate ( 60 ) is fixedly positioned on a base assembly ( 20 ) and is positioned adjacent one side of the tubing (T). The fixed gate ( 60 ) has a pair of locking ribs ( 66 ) for engaging the movable body ( 30 ) and has a roller ( 68 ) mounted atop the gate ( 60 ) for guiding a line (L) past the gate ( 60 ). The movable body ( 30 ) is positioned on the base assembly ( 20 ) adjacent another side of the tubing (T). The movable body ( 30 ) defines an open throat ( 32 ) for the tubing (T) and has first and second body portions ( 41 a-b) connected together by a hinge pin ( 44 ). The movable body ( 30 ) slides on the base assembly ( 20 ) to an advanced position over an opening ( 24 ) in the base assembly ( 20 ) such that the tubing (T) is positioned through the open throat ( 32 ) of the body ( 30 ). When in the advanced position, a pair of ribs ( 46 ) on movable body ( 30 ) engages the pair of ribs ( 66 ) on the fixed gate ( 60 ) to lock the body portions ( 41 a-b) around the tubing (T). Slips ( 54 ) are moved within the open throat ( 34 ) to engage the tubing (T) so that sections of tubing can be added or removed during well operations. An arm assembly ( 70 ) is pivotably attached to the fixed gate ( 60 ) for guiding one or more lines (L) and moving them nest to the tubing (T) for clamping.
