Self leveling boom system with rotatable working assembly
View Patent ↗A fire fighting vehicle having a boom system includes a working assembly attached to an end portion of the boom system. The working assembly comprises a frame pivotally mounted at a midpoint of the frame to the end portion of the boom. The frame carries a mechanical actuator that is connected to a tool capable of piercing an exterior of a structure when the mechanical actuator is actuated.
1. A working assembly for a fire fighting vehicle having a boom system, the working assembly comprising:
a frame mounted to an end portion of the boom system, the frame having a first end, a second end and a midpoint between the first and second ends;
a mechanical actuator mounted to the frame wherein the mechanical actuator is a hydraulic cylinder, the hydraulic cylinder supported between the first end and the midpoint of the frame, the hydraulic cylinder having a piston rod extendable toward the second end of the frame; and
a tool axially aligned with and connected to the piston rod, the tool configured to pierce an exterior of a structure via movement of the mechanical actuator.
2. The working assembly of claim 1 , wherein the frame is pivotally mounted to the end portion of the boom system.
3. The working assembly of claim 2 , wherein the midpoint of the frame is pivotally mounted to the end portion of the boom system.
4. The working assembly of claim 3 , wherein the frame further comprises a rotary actuator secured at the midpoint of the frame.
5. The working assembly of claim 1 , wherein the tool comprises a lance having a first end configured to deliver a fluid and a second end connected to the piston rod of the hydraulic cylinder.
6. The working assembly of claim 5 , wherein the lance comprises a hollow body, the hollow body having a port for connection to a fluid source, the hollow body having at least one opening at the first end of the lance for delivery of fluid.
7. A working assembly for a fire fighting vehicle having a boom system, the working assembly comprising:
a frame mounted to an end portion of the boom system, the frame having a first end, a second end and a midpoint between the first and second ends;
a hydraulic cylinder having a piston rod, the hydraulic cylinder mounted to the frame near the first end of the frame, the piston rod being extendable toward the second end of the frame; and
a lance configured for connection to a fluid source, the lance having a first end connected to the piston rod of the hydraulic cylinder and a second end configured to pierce an exterior surface of a structure when the piston rod is extended toward the second end of the frame.
8. The working assembly of claim 7 , wherein the flame is pivotally mounted to the end portion of the boom.
9. The working assembly of claim 8 , wherein the midpoint of the frame is pivotally mounted to the end portion of the boom system.
10. The working assembly of claim 9 , wherein the frame further comprises a rotary actuator secured at the midpoint of the frame.
11. The working assembly of claim 7 , wherein the second end of the lance is configured to deliver a fluid.
12. The working assembly of claim 7 , wherein the lance comprises a hollow body, the hollow body having a port for connection to a fluid source, the hollow body having at least one opening at the second end of the lance for delivery of fluid.
13. A working assembly for a fire fighting vehicle having a boom system, the working assembly comprising:
a frame mounted to an end portion of the boom system, the frame having a first end, a second end and a midpoint between the first and second ends; and
means connected to the frame for piercing through an exterior surface of a structure, wherein the means for piercing through the exterior surface of a structure comprises:
a hydraulic cylinder having a piston rod, the hydraulic cylinder mounted to the frame near the first end of the frame, the piston rod being extendable toward the second end of the frame; and
a lance configured for connection to a fluid source, the lance having a first end connected to the piston rod of the hydraulic cylinder and a second end configured to pierce an exterior surface of a structure when the piston rod is extended toward the second end of the frame.
14. The working assembly of claim 13 , wherein the frame is pivotally mounted to the end portion of the boom system.
15. The working assembly of claim 14 , wherein the midpoint of the frame is pivotally mounted to the end portion of the boom system.
16. The working assembly of claim 15 , wherein the frame further comprises a rotary actuator secured at the midpoint of the frame.
17. The working assembly of claim 13 , wherein the lance comprises a hollow body, the hollow body having a port for connection to a fluid source, the hollow body having at least one opening at the first end of the lance for delivery of fluid.
