Winch load indicator
An indicator for use with a winch is disclosed. It includes; a sensor for determining the load on a winch, a controller in communication with the sensor, and a load indicator comprising multiple lights in an array. Each of the lights in the array can be changed by the controller from one appearance to another. The controller is configured to change the appearance of each of the lights in the array, with the number of lights with a changed appearance being proportional to the load sensed by the sensor. Preferably, the indicator is incorporated into a fairlead for use with a winch.
1. An indicator for use with a winch comprising:
a sensor for determining the load on a winch;
a controller in communication with the sensor;
multiple lights in an array, each of which can be changed by the controller from one appearance to another;
wherein, in response to a signal from the sensor, the controller is configured to change the appearance of lights in the array, with the number of lights with a changed appearance being proportional to the load sensed by the sensor; and
wherein the array begins with all the lights showing one color when there is no load on the winch; and
wherein, as a load is applied to the winch, one light first changes to another color; and
wherein, as the load is increased, more lights change to the other color according to the load on the winch.
2. The invention of claim 1 , wherein all the lights change to the other color when the maximum load is reached.
3. The invention of claim 1 , wherein the sensor is a current sensor.
4. The invention of claim 3 , wherein the sensor is a non-contact open loop sensor.
5. The invention of claim 1 , wherein the one color is green, and the other color is red and wherein all the lights change to red when the maximum load is sensed.
6. The invention of claim 5 , wherein the lights progressively change colors to indicate the load on the winch.
7. The invention of claim 6 , wherein the lights change from green to yellow to orange to red.
8. The invention of claim 1 , wherein the number of lights is 12.
9. The invention of claim 1 , wherein the controller is adapted to communicate with and receive commands from a remote-control device.
10. The invention of claim 9 , wherein the remote-control device includes a user interface adapted to display the load on the winch.
11. The invention of claim 10 , wherein the remote-control device is adapted to display an alert at a user determined percentage of a maximum load on the winch.
12. A fairlead for use with a winch comprising:
a sensor for determining the load on a winch;
a controller in communication with the sensor;
multiple lights in an array, each of which can be changed by the controller from one appearance to another;
wherein, in response to a signal from the sensor, the controller is configured to change the appearance of lights in the array, with the number of lights with a changed appearance being proportional to the load sensed by the sensor
wherein the array begins with all the lights showing one color when there is no load on the winch; and
wherein, as a load is applied to the winch, one light first changes to another color; and
wherein, as the load is increased, more lights change to the other color according to the load on the winch.
13. The invention of claim 12 , wherein the fairlead is integrated into a winch.
14. The invention of claim 13 , wherein the winch is adapted to communicate with and receive commands from a remote-control device.
15. The invention of claim 14 , wherein the remote-control device includes a user interface adapted to display the load on the winch.
16. The invention of claim 14 , wherein the remote-control device is adapted to display an alert at a user determined percentage of a maximum load on the winch.
17. The invention of claim 14 , wherein the remote-control device is adapted to issue a command to the winch to stop spooling the line in when the current draw reaches a user-selected percentage of a maximum current draw.
