Aerial-ladder truck with bed extensions
View Patent ↗This disclosure pertains to industrial trucks, and in particular to aerial-ladder trucks with bed extensions. An aerial-ladder truck consistent with the present disclosure includes a cab at a front thereof and a truck bed at a rear thereof. The back end portion of the truck bed includes bed extensions that are slidably coupled in a transverse direction to the back end portion of the truck bed. When the bed extensions are engaged, the width of the truck bed increases by a length that the bed extensions extend from the truck bed. The aerial-ladder truck further includes a ladder turret provided to the truck bed to pass there through. The aerial-ladder truck further includes an extensible post fixedly passing through the ladder turret, an extensible ladder connected to a top portion of the extensible post, and a carrier provided at the top thereof.
1. An aerial-ladder truck, comprising:
a cab at front thereof and a truck bed at a rear thereof;
wherein the truck bed has a front end portion and a back end portion, the back end portion having at least one bed extension that is slidably coupled in a transverse direction to the back end portion of the truck bed;
wherein when the at least one bed extension is engaged, the width of the truck bed increases by a length that the at least one bed extension extends from the back end portion of the truck bed;
a ladder turret provided to the truck bed to pass there through;
an extensible post fixedly passing through the ladder turret and standing upright, the height of a top thereof being adjustable;
an extensible ladder having a rear end connected to the top of the extensible post by a first hinge shaft so that an angle of the extensible ladder relative to the truck bed thereof is changeable, and a moving bucket provided at the top of the extensible ladder;
an angle adjusting cylinder for changing the angle of the extensible ladder; and
a tailgate component pivotably coupled to said back end portion of said truck bed between an open and a closed position; wherein, a pair of collapsible lateral surfaces extends pivotably from said tailgate component, when said tailgate component is in said open position.
2. The aerial-ladder truck of claim 1 , wherein the tailgate component includes a plurality of cavities therein.
3. The aerial ladder truck of claim 1 further comprising a door stopper which can be extended from the truck bed to provide support for the tailgate component when open.
4. The aerial-ladder truck of claim 1 , wherein the at least one bed extension includes a bed extension on both lateral sides of the truck bed.
5. The aerial-ladder truck of claim 1 , wherein the at least one bed extension includes three bed extensions on a first side and a second side of the truck bed.
6. The aerial-ladder truck of claim 5 , wherein each bed extension can be extended independent of each other.
7. The aerial-ladder truck of claim 1 , wherein the at least one bed extension includes a locking mechanism wherein when engaged, allows the at least one bed extension to extend from a side of the truck bed, and when disengaged, restricts the at least one bed extension from extending from the side of the truck bed.
8. The aerial-ladder truck of claim 7 , wherein the locking mechanism includes a set of pins.
9. The aerial-ladder truck of claim 1 , wherein the at least one bed extension includes a handle for engaging the at least one bed extension.
10. The aerial-ladder truck of claim 1 , wherein the at least one bed extension includes a plurality of ridges disposed on a top surface thereon.
11. The aerial-ladder truck of claim 1 , wherein the angle-adjusting cylinder has a rear end connected at the front of the top of the extensible post by a second hinge shaft and a front end connected to the bottom of the extensible ladder by means of a third hinge shaft.
12. The aerial-ladder truck of claim 1 , wherein the at least one bed extension is adjacent to a rear end of the truck bed.
13. The aerial-ladder truck of claim 1 , wherein when engaged, at least one expander surface of the bed extensions extends two feet from an edge of the truck bed.
14. An aerial-ladder truck, comprising:
a cab at a front thereof and a truck bed at a rear thereof;
wherein the truck bed has a front end portion and a back end portion, the back end portion having at least one bed extension that is slidably coupled in a transverse direction to the back end portion of the truck bed;
wherein when the at least one bed extension is engaged, the width of the truck bed increases by a length that the at least one bed extension extends from the back end portion of the truck bed;
a tailgate component pivotably coupled to said back end portion of said truck bed between an open and a closed position; wherein, a pair of collapsible lateral surfaces extends pivotably from said tailgate component, when said tailgate component is in said open position;
a door stopper which can be extended from the truck bed to provide support for a tailgate when the tailgate is open;
a ladder turret provided to the truck bed to pass therethrough;
an extensible post fixedly passing through the ladder turret and standing upright, the height of a top thereof being adjustable;
an extensible ladder having a rear end connected to the top of the extensible post by a first hinge shaft so that an angle of the extensible ladder relative to the truck bed is changeable, and a moving bucket provided at the top of the extensible ladder; and
an angle adjusting cylinder for changing the angle of the extensible ladder relative to the truck bed.
15. The aerial-ladder truck of claim 14 , wherein the at least one bed extension comprises aluminum.
16. The aerial-ladder truck of claim 14 , wherein the length of the at least one expander surface of the at least one bed extension is in the range of 2-5 feet.
