Foldable safety apparatus for an upper region of a ready-mix concrete truck

Foldable safety apparatus for providing fall protection for a person when on an elevated element on a ready-mix concrete truck, comprising:

• support members located above and adjacent to opposite sides of the elevated element, respectively;
• an elongate, rigid railing element having opposite end portions pivotally connected to the support members, respectively, such that the railing element is supported above a peripheral portion of the elevated element generally between the opposite sides thereof, the railing element having a generally concave portion extending between the end portions thereof;
• and
• an elongate arm having a first end portion pivotally connected to the railing element, such that the arm extends downwardly therefrom to a location below the elevated element, the arm being movable for pivotally moving the railing element between a deployed position wherein the concave portion extends outwardly from the support members and the elevated element a predetermined distance above the elevated element, and a stored position angularly related to the deployed position, the arm having a second end portion opposite the first end portion thereof supportable on an element of the truck for holding the railing element in the deployed position.

Foldable safety apparatus for above a peripheral region of an elevated platform on a ready-mix concrete truck including a ladder extending upwardly to the peripheral region of the platform, the safety apparatus comprising:

• support members located above and adjacent to opposite sides of the peripheral region, respectively;
• an elongate, rigid railing element having opposite end portions pivotally connected to the support members, respectively, such that the railing element is supported above the peripheral region, the railing element including an intermediate portion disposed between the opposite end portions thereof, the intermediate portion having a generally concave shape defining a predetermined area;
• and
• an arm having a first end connected to the railing element and extending downwardly therefrom, movable for pivotally moving the railing element between a first position extending outwardly from the support members generally above the peripheral region such that the predetermined area is generally above the predetermined region, and a second position angularly related to the first position wherein the intermediate portion extends across the peripheral region for obstructing passage through an area above the peripheral region.

Foldable safety apparatus for providing fall protection for a person when on an elevated element on a ready-mix concrete truck, the elevated element being located above a ladder on the truck having an upper portion and a lower portion, the lower portion being mounted for pivotal movement relative to the upper portion between a folded position generally beside the upper portion and an unfolded position extending downwardly from the upper portion, the safety apparatus comprising:

• an elongate, rigid railing element having opposite end portions pivotally connected to elements on the truck, respectively, such that the railing element is supported above a peripheral portion of the elevated element, the railing element having a generally concave intermediate portion extending between the end portions thereof;
• and
• an elongate arm having a first end portion pivotally connected to the railing element and extending downwardly therefrom to a second end portion of the arm pivotally connected to the lower ladder portion, such that the arm is movable by upward movement of the lower ladder portion relative to the upper ladder portion to move the railing element to a deployed position wherein the concave intermediate portion thereof extends outwardly above the peripheral portion of the elevated element, and the arm is movable by downward movement of the lower ladder portion to move the railing element from the deployed position to a stored position angularly related to the deployed position and extending across an area above the peripheral region of the elevated element for impeding movement of a person between the elevated element and the ladder.
