Excavation sling

The Excavation sling is the lift that carries Roberta “Bobbi” Anderson and James Eric Gardener between the surface and the trench containing the buried ship. Long used as ordinary excavation equipment, it becomes more than a means of access when the pair decide to descend together: its controls are out of reach from below, and a modified Electrolux vacuum cleaner must operate them. The sling’s simple up-and-down motion thus exposes the dependence of their work on improvised machinery—and, increasingly, on Bobbi’s uncanny command of it.

Design and operation

The sling is controlled by two switches. At the bottom, a button starts its movement; at the top, a conventional electrical switch is mounted on a support post beneath the lean-to, fifty feet from the trench’s edge. The arrangement had not seemed troublesome while the pair used the sling routinely. But once they consider how to get down, the distance between the controls becomes an immediate practical problem: neither person can reach the switch above from the trench, and their arms are considerably shorter than fifty feet.

That inconvenience also reveals how thoroughly routine has concealed the device’s limitations. Bobbi and Gardener have been riding the sling for a long time, but have never descended together. Either could have gone down alone while the other operated the bottom button. Instead, they understand without discussing it that this descent must be shared, both standing with one foot in the sling’s single stirrup and their arms around each other’s waists. The machinery offers no built-in accommodation for two riders or for remote operation; each requirement has to be met in the moment.

Remote control by the modified Electrolux

Bobbi’s solution turns an old Electrolux vacuum cleaner into an operator. It trundles across the beaten earth to the lean-to and stops below the switchbox. A click and a hum precede a thin black length rising from its side. Gardener first sees it as a rope; it is coaxial cable, moving upward toward the controls with a motion that strikes him as blind yet searching.

The cable reaches the black button that starts the sling, presses it, and holds it in. When the sling has descended about twelve feet, the cable slackens, finds the red Stop button, and presses that instead. It then returns to the black button, restarting the motor; the sling rises, and at the top the motor stops automatically. The sequence demonstrates that the Electrolux can operate both switches, not merely trigger a one-way descent. Bobbi watches with a smile and says, “There,” she said. “Works fine.”

Gardener’s amazement is mixed with unease. He notices that Bobbi is not gesturing with a radio to direct the machine; instead, he sees the brief frown of concentration and the moment her eyes drop just before the cable moves from the start button to the stop button. The sling’s remote operation looks mechanical, but the scene associates its precise timing with Bobbi’s attention. Her improvised device is useful precisely where ordinary controls fail, while its apparent responsiveness makes the boundary between tool and operator harder to take for granted.

The shared descent and return

Once the cable has demonstrated the controls, Bobbi rides down first while it runs the switches. The sling comes back up for Gardener, who holds the rope as it begins its second descent. He looks back at the battered Electrolux before entering the trench, where the ship rises beside him through the dimness. The two do not, in fact, make the first descent together: the machine’s new function allows them to go down in sequence while preserving access to the controls.

The sling also becomes the focus of Gardener’s suspicion later in the ship. He imagines Bobbi might send him up and leave him below, trapped beside the hatch; the imagined betrayal turns an ordinary piece of equipment into a possible means of abandonment. Bobbi insists that he go up first, and her look indicates that she understands his suspicion without needing to read his mind. The sling does bring him back to the surface, but that passage is physically punishing: he clings to the cable, fights nausea, and emerges with a severe nosebleed. Bobbi sends a warning not to remove his mask until he is topside, explaining that the trench air remains dangerous and may not equalize with the air outside for the rest of the day, perhaps longer.

Narrative significance

The Excavation sling’s role shifts from familiar convenience to a test of coordination, trust, and risk. Its inaccessible controls make the limits of the excavation arrangement visible just as Bobbi and Gardener insist on sharing a descent that could have been done separately. The Electrolux bridges the gap, but does so in a way that seems to give a commonplace machine a searching, purposeful motion and links its actions to Bobbi’s concentration.

Later, Gardener’s fear that Bobbi could strand him below the hatch shows how the same mechanism can be imagined as a means of control as well as transport. Yet she sends him up first, and the return exposes a more immediate danger than his suspicion: the air itself is unsafe, and the trip out leaves him bleeding and sick. The sling is therefore neither a guarantee of safety nor merely a neutral conveyance. It is the narrow, improvised connection between the dangerous space around the buried ship and the surface, controlled by machinery whose apparent responsiveness both enables their work and sharpens their mistrust.
