Radio-controlled cargo truck ramp load assist system
View Patent ↗A cargo truck ramp load assist system comprises a hand truck engagement device disposed in a longitudinal slot in a cargo truck ramp, a first actuator coupled to the hook operable to effect displacement of the hand truck engagement device along the longitudinal slot in the ramp, a remote controller coupled to a hand truck and equipped with a first radio transceiver, a second radio transceiver coupled to the first actuator operable to receive directional/speed control signals from the remote controller, and the hand truck engagement device operable to engage the hand truck and the first actuator effecting displacement of the hand truck engagement device up and down the ramp in response to the directional/speed control signals to facilitate the hand truck going up and down the ramp.
1. A cargo truck ramp load assist system, comprising:
a hand truck engagement device disposed in a longitudinal slot in a cargo truck ramp;
a first actuator coupled to a hook operable to effect displacement of the hand truck engagement device along the longitudinal slot in the ramp;
a remote controller coupled to a hand truck and equipped with a first radio transceiver;
a second radio transceiver coupled to the first actuator operable to receive directional/speed control signals from the remote controller; and
the hand truck engagement device operable to engage the hand truck and the first actuator effecting displacement of the hand truck engagement device up and down the ramp in response to the directional/speed control signals to facilitate the hand truck going up and down the ramp.
2. The system of claim 1 , further comprises a second actuator operable to raise and lower the hook.
3. The system of claim 1 , wherein the remote controller further comprises a user interface configured to receive directional/speed inputs from an operator.
4. The system of claim 3 , wherein the user interface comprises:
a directional control interface configured to receive a directional input from the operator;
a speed control interface configured to receive a speed input from the operator; and
a hook control interface configured to receive a hook raising and lowering input from the operator.
5. The system of claim 1 , wherein the first actuator comprises a variable speed motor.
6. The system of claim 1 , further comprising a cable and pulley system coupled to the first actuator and configured to effect displacement of the hook along the longitudinal slot in the ramp.
7. The system of claim 1 , wherein the hand truck engagement device comprises a hook configured to engage a component of the hand truck.
8. The system of claim 1 , wherein the remote controller further comprises a visual indicator configured to visually provide system operational status.
9. A cargo truck ramp load assist system, comprising:
a hook disposed in a longitudinal slot in a cargo truck ramp;
a first actuator coupled to the hook operable to effect displacement of the hook along the longitudinal slot in the ramp;
a second actuator coupled to the hook operable to effect raised and lowered positions of the hook;
a user interface configured to receive control input from an operator;
a remote controller coupled to a hand truck and equipped with a first radio transceiver, the first radio transceiver configured to transmit the control input from the operator;
a second radio transceiver coupled to the first actuator operable to receive the control input from the remote controller; and
the hook operable to engage the hand truck and the first actuator effecting displacement of the hook up and down the ramp and the second actuator effecting raised and lowered positions in response to the control input to facilitate the operation of hand truck going up and down the ramp.
10. The system of claim 9 , wherein the user interface comprises:
a directional control interface configured to receive a directional input from the operator;
a speed control interface configured to receive a speed input from the operator; and
a hook control interface configured to receive a hook raising and lowering input from the operator.
11. The system of claim 9 , wherein the first actuator comprises a variable speed motor.
12. The system of claim 9 , further comprising a cable and pulley system coupled to the first actuator and configured to effect displacement of the hook along the longitudinal slot in the ramp.
13. The system of claim 9 , wherein the remote controller further comprises a visual indicator configured to visually provide system operational status.
14. A remote-controlled cargo truck ramp loading method, comprising:
elevating a hook disposed in a longitudinal slot in the cargo truck ramp;
engaging a hand truck carrying a load with the hook;
facilitating the hand truck going up or down the ramp via remote controlling the displacement of the hook along the longitudinal slot; and
lowering the hook.
15. The method of claim 14 , further comprising receiving an operator input to elevate and lower the hook.
16. The method of claim 14 , further comprising receiving an operator input to displace the hook in a specified direction along the longitudinal slot up and down the ramp.
17. The method of claim 14 , further comprising receiving an operator input to displace the hook according to a speed setting along the longitudinal slot up and down the ramp.
18. The method of claim 14 , further comprising providing a visual indication of direction and speed operational status to the operator.
