The bulkhead plug is plugged into the signal socket and the controller plug is plugged into the cab bridge controller for transfer of at least one electrical signal from the at least one of electric joystick, at least one electric treadle, a button panel and an operator display to the cab bridge controller. A vehicle controller is preferably used to receive electrical signals from the button panel and the operator display. The vehicle controller is also used to display information to an operator display. The vehicle controller is also connected to the cab bridge controller.
An output from the cab bridge controller is connected to the cab transceiver. A power cable includes a generator plug on one end and a power plug on an opposing end. The generator plug is connected to an electrical generator and the power plug is plugged into the power socket. With the electric generator connection, the remote wireless electric cab is capable of operating remotely from the remote wireless electric frame through wireless communication.
A docking station may be used to provide a physical foundation and an operational base for the remote electric cab. The docking station includes a base member and an electrical generator. The base member includes a support base and at least two upright mounting members. The at least two upright mounting members extend upward from the support base. A fastener threaded tap or hole is formed through a top of each upright mounting members. The electrical generator is preferably attached to a top surface of the support base. The remote wireless electric cab is preferably attached to the at least two upright mounting members with four fasteners. The electrical generator is connected to the electrical bulkhead through the power cable.
The remote wireless electric frame preferably includes a frame member, a frame transceiver and a frame bridge controller. The frame member preferably includes a frame support, an engine, at least one electrical component, a plurality of hydraulic components and at least one tool. The engine, the at least one electrical component, the plurality of hydraulic components and the at least one tool are retained on the frame support. An electrical control signal originates from the at least one electric joystick, the at least one electric treadle, the electrical button panel or the display touch screen. The electrical button panel includes a plurality of buttons and knobs. The electric joystick, electric treadle, electrical button panel and display touch screen are located in the cab enclosure. Electrical control signals from the electric joystick, the electric treadle, the button panel and the display touch screen are converted into a suitable protocol by the cab bridge controller and sent to the cab transceiver. The cab transceiver wirelessly transmits the electrical control signals to the frame transceiver.
The frame bridge controller receives electrical control signals from the frame transceiver and converts the signals into a suitable form. The electrical control signals are sent from the frame bridge controller to a hydraulic controller, an engine controller and at least one electrical component. The electrical control signals from the joystick and the treadle are sent to the hydraulic controller to control a tool and a plurality of hydraulic components on the frame support. Electrical control signals from the button panel and the operator display are sent to the engine controller or the at least one electrical component.
Accordingly, it is an object of the present invention to provide a remote wireless electric frame, which is used in conjunction with a remote wireless electric cab for remote operation of the remote wireless electric frame and the at least one tool by the remote wireless electric cab.
These and additional objects, advantages, features and benefits of the present invention will become apparent from the following specification.
With reference now to the drawings, and particularly to
An output from the cab bridge controller 20 is connected to the cab transceiver 22. The cab bridge controller 20 converts the electrical signals from the at least one electric joystick 25, at least one electric treadle 27 and the vehicle controller 45 into a suitable form for wireless transmission. The cab transceiver 22 transmits the plurality of electrical signals from the signal socket 42 to a frame transceiver 52. The frame transceiver 52 sends the electrical signals to a frame bridge controller 53. A power cable 54 includes a generator plug 56 on one end and a power plug 58 on an opposing end. The generator plug 58 is plugged into an electrical generator 106 and the power plug 56 is plugged into the power socket 44. The at least one electric joystick 25 and the at least one electric treadle 27 are powered by the electric generator 106 through the power cable 54. With the electric generator 106 connections, the electric cab 1 is capable of operating remotely with the electric frame 2 through wireless communication.
The docking station 12 may be used to provide a physical foundation and an operational base for the electric cab 1. The docking station 12 includes a base member 60 and the electrical generator 106. The base member 60 includes a support base 62 and at least two upright mounting members 64. The at least two upright mounting members 64 extend upward from the support base 62.

The cab bridge controller 20 and the cab transceiver 22 may be retained on the cab member 14 or the support base 62. The electrical generator 106 is attached to a top surface of the support base 62. With reference to
However, the electric cab 1 does not have to be used with the docking station 12. The electrical generator 106 may be connected to the electric cab 1 from any other suitable source, besides the docking station 12. The cab bridge controller 20 and the cab transceiver 22 could be physically retained on the cab enclosure 14 and not on the docking device 12.

The operator display 49 includes the touch screen. The at least one electric joystick 25, at least one electric treadle 27, electrical button panel 47 and touch screen 49 are located in the cab enclosure 14. The electrical control signals are sent to the cab bridge controller 20. The electrical control signals are converted into a suitable protocol by the cab bridge controller 20 and sent to the cab transceiver 22. The cab transceiver 22 wirelessly transmits the electrical control signals to the frame transceiver 52.
The frame bridge controller 53 receives the electrical control signals from the frame transceiver 52 and converts the signals into a suitable form.
