High-altitude work platform with a horseshoe-shaped fastener and folding seat for securing ladders to utility poles

This technology is a ladder safety device that secures a leaning ladder to an external structure, such as a utility pole, by attaching a support frame to the ladder rungs under a hollow, rim-style main frame that allows the worker to pass through, and fastening the front locking mechanism to the structure. A folding seat is attached to the rear of the main frame with a hinge, allowing the worker to sit while working on the ladder.

High-altitude work is often performed by climbing ladders, and if the ladder is not properly secured, it can wobble or tip over, leading to falls. Such accidents are particularly common on cylindrical structures like utility poles where the ladder only makes contact at a single point. Existing safety devices that use curved supports to lean the ladder against the structure have failed to fully secure the ladder, leaving risks unresolved.

This technology uses a horseshoe-shaped frame to wrap around the structure, tightened by fasteners at both ends, and includes a preliminary fixture for temporary stabilization before final tightening to prevent wobbling during installation. The support frame's base wraps around the ladder rungs and locks with a hinge to prevent detachment. Safety hooks can be attached to handles on both sides of the main frame, and a detachable backrest helps reduce the risk of falling backward. Applicable to utility pole maintenance, street light and traffic signal repair, and telecommunications equipment installation, it provides a stable, fixed platform that allows workers to sit while working on ladders that were previously unstable.

Key Features:
  • A main frame with an open interior rim that allows a worker to pass through
  • A folding seat hinged to the rear of the main frame that covers a portion of the rim
  • A plurality of support frames coupled to the bottom of the main frame, designed to hold the base of a ladder leaning against an external structure
  • A locking mechanism coupled to the front of the main frame that secures the ladder to the external structure for safe installation
