This technology is a fall prevention device consisting of a footrest with an insertion part that installs into the outer surface of a utility pole and a support part with a cross-section wider than it is tall, along with a sole component fixed to safety shoes that features multi-angled, overlapping grooves designed to fit the footrest. When a worker steps on the footrest, the grooves in the sole interlock with the footrest to prevent the foot from slipping.
Utility pole workers climb up and down by stepping on rod-shaped metal step bolts while wearing safety shoes, but fatal accidents involving falls from heights of up to 10 meters while changing positions have occurred consistently. Existing technology, which applies anti-slip metal particles to the surface of step bolts, becomes slippery again once the particles or shoe soles wear down, and it has limitations in that it easily slips even with slight movement while standing on the bolt, not just during climbing.
In this technology, the temporary coupling grooves of the sole component are formed to overlap at various stepping angles, ensuring they interlock with the footrest regardless of the angle of approach. Additionally, directional protrusions extending along the insertion part prevent the support from wobbling. The head at the end of the footrest features a through-hole for attaching a worker's safety lanyard, with a diameter set to no more than half the width of the support. Applicable to utility pole climbing steps, street light or tower inspection footrests, and safety shoes for electrical workers, this device reduces slip-related falls when standing or moving without requiring major changes to existing step bolt structures.
