SAFETY CLIMB ATTENUATION APPARATUS
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.

BALANCE MOBILE ANCHOR CART
An anchor cart assembly can include a cart including a frame defining at least one front foot and at least one rear foot, the at least one front foot and the at least one rear foot defining a bottom plane of the frame; and an axle assembly mounted to the frame, the axle assembly being repositionable relative to the frame between a raised position and a lowered position, the axle assembly positioned above the bottom plane in the raised position, at least a portion of the axle assembly positioned below the bottom plane in the lowered position; and a load supported by the cart.
FALL HAZARD SAFETY SYSTEM
A fall hazard safety system includes first and second base units movable with respect to each other. First and second support members are secured to and extend from the first and second base units, respectively. A crossbeam is securable to the first and second support members. A tether is secured to the crossbeam and is securable to a harness for harnessing an individual when support on an elevated surface and for reducing a fall hazard of the individual falling from the elevated surface.
REBAR BITER
A device may include an anchor point operationally connected to a rebar, an E-clamp coupled to the anchor point, and a forcing handle configured to tighten the E-clamp to the rebar.
Band spacing in fall protection system
This invention provides fall protection systems, in metal building construction, and methods of installing such systems. A given such system comprises a suspension fabric, supported by a grid-work of longitudinal and lateral support bands. The distance of the safety band from the rafter corresponds to about 40 percent to about 75 percent of the diameter of the bag. Thus for a 30-inch diameter bag, the distance between the edge of the rafter and the middle of the safety band is about 12 inches to about 23 inches. The safety band protects the suspension fabric from being cut by the near edge of the rafter when a falling object impacts the fall protection system near the edge of the rafter.
Fall protection apparatus
A fall protection apparatus includes a heavy support base with a pivotal mast having a top member for rotation around the axis of the mast carrying a series of booms pivotal about respective vertical axes, each having an end coupling member for receiving a fall restraint harness. Each boom is formed by a tube which fractures on a fall and an elongate stainless steel strap inside the tube which bends without fracturing. The mast includes a series of telescopic rectangular mast sections with a winch driven cable and pulley arrangement for extending the first section which acts to pull the second inner section to the extended position as the first inner section moves out of the outer section. Each section includes first and second pulleys mounted at the same face of the section with the cable located between the face of the section and the face of the next section.
Variable-height attachment point system for a safety harness
Systems and methods relate to a operator selectable, variable-height attachment point system for a safety harness, where the attachment point is disposed on a radial support member that can be reversibly coupled to a vertical support member, and where the attachment point height can be selected by the operator by reversing a coupled orientation of the radial support member to the vertical support member.
Mobile fall protection unit for flatbed platforms
A mobile fall protection unit can be maneuvered by hand and brought to a flatbed with readily deployable, temporary fences for worker fall protection. The mobile fall protection unit can include a chassis, which carries a frame, which in turn carries a ladder as well as selectively deployable fall protection devices for worker fall protection. The frame carries a pair of retractable fall barriers separated from each other by about the width of the back of the flatbed.
Safety band longitudinal and transverse control
This invention provides fall protection systems comprising a suspension fabric, supported by a grid-work of longitudinal and lateral bands, in metal building construction. The fall protection system uses the combination of relatively softer banding, a safety band spaced a particular distance from each rafter, and safety clips to attach the safety bands to the intermediate purlins, thus to distribute the force of impact of a load, falling close to a rafter, to better absorb and dissipate the force of the impact, including distributing the impact of the falling load over a greater area of the roof structure. The invention further provides methods of making elements of such systems, methods of installing elements of such systems, and buildings embodying such systems.
