Abstract: A worker-lifting unit such as a boom lift or scissors lift may be provided with fall-arresting system for a worker. The fall-arresting system may include a worker-support device enclosed by guard rails and an anchoring point for a fall-arresting harness of the worker. The anchoring point may be positioned on the worker-support device high enough so that, when the worker is in the device, the anchoring point is above the worker's harness. Thus the worker may safely leave the device, when it is in a raised position, while the worker's fall-arresting harness may remain attached to the anchoring point.
