A tether system for a safety line has an elongate guide track and stay elements arranged to move along the guide track and be carried at spaced positions along the length of a tether line. The system is typically employed in a fall arrest or protection system mounted to a structure, having an ascent/descent ladder fixed to the structure, the system including a self-retracting safety line device including a safety line, mounted at height.

A safety device for a ladder for protecting a user of the ladder is provided. The safety device includes a guard member formed extending in one direction, the guard member being mountable on the ladder, and a plurality of fixing members connected to the guard member, spaced apart from each other along a longitudinal direction of the guard member, and configured to fix the guard member to the ladder, wherein the guard member is configured to protrude at least partially toward a mar side of the ladder and cover a rear surface of the ladder.

In one embodiment, an electronically controlled hatch system for safe ingress, egress, hazard detection, and methods thereof are provided to reduce or eliminate hazards to personnel, including protection of people above and below a scuttle hatch, access port, skylight or elevated deck. Said hatch system reduces the risk of falls while ascending or descending a ladder through an access port. In certain embodiments, severe weather, hazard, security, and other safety information are detected and transmitted to a central control unit for processing and regulating the opening and closing of a hatch covering the access port and/or raising and lowering a safety railing system based on said information and/or user input. Said hatch system may include an actuator and guides for automatically locking/unlocking and opening/closing a hatch, an actuator and guides for automatically raising/lowering a railing system, safety monitoring detectors/apparatuses, and a centralized controller.

The present invention provides a hoisting device for working in heights, specifically including a vehicle body, a lower bracket installed at a bottom of a safety ladder, a host driver fixed on the lower bracket and providing lifting power, an upper bracket installed at a top of the safety ladder, a traction rope connecting the upper bracket, the vehicle body and the host driver, and a sliding rail installed on the safety ladder, and further including a fall arrester installed on the sliding rail, a guiding device assembly installed on a back portion of the vehicle body, a stall protection device installed on the vehicle body and matched with the sliding rail, a collapsible pedal installed on a lower portion of the vehicle body and configured to carry people and goods, an operation handle fixed to an upper portion of the vehicle body and a position-limiting bracket installed on an upper portion of the safety ladder. The host driver drives, trough the traction rope, the vehicle body to ascend or descend along the sliding rail, thus enabling the vehicle body to ascend or descend so as to convey people and goods. The hoisting device is simple and convenient to operate, occupies a small floor space and can be installed without changing a structure of an original safety ladder.
