Safety climb attenuation apparatus
11925822 · 2024-03-12 · ·

A safety climb attenuation apparatus provides a more robust and visually inspectable apparatus for climbing safety. In an upper bracket, a pivot arm is attached to a base that is disposed upon a structure. The upper bracket includes an attenuation member such as an elastic bushing, mounted on the pivot arm or the base, that resists pivoting of the pivot arm relative to the base when a safety cable attached to the pivot arm causes the pivot arm to pivot. In a lower bracket, a similar attenuation member is attached to a base disposed on the structure, with an anchor bolt connecting the cable to the attenuation member so that the attenuation member resists upward movement of the cable.

Fall arrest system
10486002 · 2019-11-26 · ·

A fall arrest system for a silo having a ladder is described. Silos typically have a slopping top and substantially vertical sides. Typically, multiple independent fail arrest systems are used, one for the sloping top and one for the vertical sides. The single fall arrest system described includes: a safety cable, having a top end and a bottom end, to which in use a user connects to; a collar for fitting at the top of the silo, around the neck of the silo to which the top end of safety cable is attached; a pulley at the transition of the slopping top and substantially vertical sides, wherein the pulley supports the safety cable at the transition; and securing means for securing the bottom of the safety cable at the base of the silo.

INTEGRATED CLIMB ASSIST AND FALL ARREST SYSTEMS AND METHODS
20190338593 · 2019-11-07 ·

Integrated climb assist and fall arrest system and methods to assist users climbing ladders and vertical paths are disclosed. The integrated systems and comprise a controller connected to a user's harness, a static fall arrest cable, and a movable climb assist belt. The connection of the fall arrest components and the climb assist components may include physical connection, electronic connection, communication, or any combination thereof. The climb assist belt can be driven by a motor to provide an upwards climb assistance force to a user along a vertical path. The motor can be dynamically adjusted to continuously provide a level of climb assistance. The integrated controller is also configured to mechanically detect downwards movement and engage an overspeed braking mechanism when a threshold velocity or acceleration is detected.

Pass-Through Cable Grab System
20190277088 · 2019-09-12 ·

A pass-through cable grab system which allows a workman wearing a harness to move up and down a ladder on a tower or similar structure while being protected from falling by a vertically extending safety cable attached to the tower. The system includes at least one standoff bracket having a rear end secured to the tower and a forward end secured to the cable. A cable grab assembly includes a housing that can move vertically up and down the cable and further includes a brake mechanism. A lever extends from the housing and is connected to the workman through a lanyard. In the event of a fall, the lever moves downwardly activating the brake mechanism. The housing includes a vertically extending slot which allows the cable grab assembly to pass over the forward end of the standoff bracket as the cable grab assembly moves up and down. The standoff bracket also includes cam surfaces adjacent the top and bottom thereof which engage the housing as it moves toward the bracket to properly align the cable grab assembly so that it can pass over the standoff bracket.

Cable Guide for Fall Protection System

A cable guide for stabilizing a safety cable of a fall protection system. The cable guide includes an elongate member with an engaging end that is arcuately deflectable relative to a stationary end of the elongate member and that comprises a magnet.

Tether system for a safety line
10370898 · 2019-08-06 · ·

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.

CABLE SLEEVE FOR FALL PROTECTION SYSTEM

A cable sleeve for use with a safety cable of a fall protection system. The cable sleeve has a braking system that includes a constant-contact wheel, a rotor that is connected to the constant-contact wheel, a cam plate, and a braking shoe. The rotor may have a permanent magnet and a magnetically susceptible item that is held in a disengaged position by the permanent magnet. Rotation of the constant-contact wheel can overcome the magnetic force and cause the item to move so as to engage with the cam plate and actuate braking by the braking shoe.

Rope based fall protection device
11998776 · 2024-06-04 · ·

A rope based fall protection device including a rotation unit, a brake unit, and a rope. A first end of the rope is connected to the rotation unit. The rope includes a first rope loop and a second rope loop that are wound around the rotation unit. A first retaining portion of a retaining ring is sleeved on the first rope loop and a second retaining portion thereof is sleeved on the second rope loop, such that the rope forms a rope section which has a fixed length between the second retaining portion and the first end and is wound around the rotation unit. When a free end of the rope is pulled by an external force to release the rope wound around the rotation unit in a direction away from the rotation unit, the retaining ring is broken to release the rope section of the rope. The external force is greater than or equal to a pulling force generated by a user's free fall. By releasing the rope section of the rope, the rotation unit rotates and simultaneously drives the brake unit to rotate to slow down or stop the rotation of the rotation unit.
