System and method for aligning portions of a loading ramp
A system for aligning outer edges of upper surfaces of ramp portions of a loading ramp. The system may include a plurality of sensors configured to provide signals indicative of whether the outer edges of upper surfaces of adjacent ramp portions are aligned. The system may also include a plurality of actuators configured to raise and lower at least one of the outer edges of an upper surface of a ramp portion. The system may also include a controller configured to receive signals from the plurality of sensors, determine whether the outer edges of upper surfaces of adjacent ramp portions are aligned, and provide signals to the actuators to affect movement thereof causing the outer edges of the upper surfaces of the adjacent ramp portions to be aligned.
1. A system for aligning outer edges of upper surfaces of ramp portions of a loading ramp, the system comprising:
a plurality of sensors configured to provide signals indicative of whether the outer edges of upper surfaces of adjacent ramp portions are aligned;
a plurality of actuators configured to raise and lower at least one of the outer edges of an upper surface of a ramp portion; and
a controller configured to:
receive signals from the plurality of sensors;
determine whether the outer edges of upper surfaces of adjacent ramp portions are aligned; and
provide signals to the actuators to affect movement thereof causing the outer edges of the upper surfaces of the adjacent ramp portions to be aligned.
2. The system of claim 1 , wherein the sensors are configured to provide signals indicative of a distance between the outer edges of upper surfaces of the adjacent ramp portions.
3. The system of claim 1 , wherein the sensors are located at opposing edges of adjacent ramp portions, and the sensors are configured to provide signals indicative of whether the sensors located at opposing edges of the adjacent ramp portions are aligned with one another.
4. The system of claim 1 , further including leveling jacks provided at outer edges of the ramp portions, wherein the leveling jacks are configured to raise and lower at least one of the outer edges of upper surfaces of the ramp portions.
5. The system of claim 4 , wherein the leveling jacks include:
a mounting device configured to be coupled to a ramp portion;
a shaft extending from the mounting device; and
a foot attached to an end of the shaft, wherein the mounting device and the shaft are configured to raise and lower at least one of the outer edges of the upper surfaces of the ramp portions.
6. The system of claim 5 , wherein the foot of the at least one leveling jack is configured to come in contact with a rail surface and at least partially support a weight of the ramp.
7. The system of claim 6 , wherein the at least one leveling jack comprises a threaded shaft and the foot comprises a nut.
8. A ramp comprising:
a plurality of ramp portions, each having a first end, a second end, and a top surface for supporting objects movable over the ramp sections;
a plurality of joints, each connecting the first end of one of the plurality of ramp portions to the second end of another of the plurality of ramp portions; and
a leveling system, including:
a plurality of sensors configured to provide signals indicative of whether the outer edges of upper surfaces of adjacent ramp portions are aligned;
a plurality of actuators configured to raise and lower at least one of the outer edges of an upper surface of a ramp portion; and
a controller configured to:
receive signals from the plurality of sensors;
determine whether the outer edges of upper surfaces of adjacent ramp portions are aligned; and
provide signals to the actuators to effect movement thereof causing at least one ramp portion to move such that the outer edges of the upper surfaces of the ramp portions are aligned.
9. The ramp of claim 8 , wherein the sensors are configured to provide signals indicative of a distance between the outer edges of upper surfaces of the adjacent ramp portions.
10. The ramp of claim 8 , wherein the sensors are located at opposing edges of adjacent ramp portions, and the sensors are configured to provide signals indicative of whether the sensors located at opposing edges of the adjacent ramp portions are aligned with one another.
11. The ramp of claim 8 , further including leveling jacks provided at outer edges of the ramp portions, wherein the leveling jacks are configured to raise and lower at least one of the outer edges of upper surfaces of the ramp portions.
12. The ramp of claim 11 , wherein the leveling jacks include:
a mounting device coupled to a ramp portion;
a shaft extending from the mounting device; and
a foot attached to an end of the shaft, wherein the mounting device and the shaft are configured to raise and lower at least one of the outer edges of the upper surfaces of the ramp portions.
13. The ramp of claim 12 , wherein the foot of the at least one leveling jack is adapted to come in contact with a rail surface and at least partially support a weight of the ramp.
