When a malfunction occurs, an operator can manipulate the override button to provide power to the override switches. The override switches can comprise jack switches, swing switches, tilt switches, traverse switches, and hoist switches to control their corresponding functions. When activated, the override switches provide power directly to hydraulic controls corresponding to each respective function and bypassing all sensor inputs including proximity sensors and switches. In one embodiment, the hydraulic controls are hydraulic coils. When a safety system of the invention, such as an emergency stop system, is activated, all override functions will be deactivated.
[0059] In an embodiment, the safety system also comprises an alarm. In another embodiment, the alarm is triggered when the jacks are moving. In yet another embodiment, the alarm is triggered when the container transport vehicle is placed in reverse. For example, when the shifter is placed in reverse, a signal is sent from the vehicle to the reverse alarm, sounding the alarm. In yet another embodiment, the vehicle comprises a reverse camera proximal to the rearward end of the vehicle that allows visualization of the area behind the vehicle on a screen.
[0060] In another embodiment, the safety system comprises work lights. In one embodiment, the work lights are controlled by a work lights electrical box. This control box canAttorney Docket No. 23749836 be as depicted in FIG. 7. The work lights can comprise lights at one or more steps of the vehicle and rear work lights on the vehicle. In another embodiment, lights around the vehicle turn on when a safety system is activated.
[0061] In one embodiment, the safety system is capable of disabling all functions of the vehicle and vehicle-mounted device described herein. In another embodiment, the emergency stop system disables one or more functions of the vehicle-mounted device described herein.
[0062] In certain embodiments of the invention, safety systems of the invention allow the jacks to only be raised when the carriage is at its forward-most position. In other embodiments, safety systems of the invention enable swing in and swing out functions only when the carriage is traversed all the way forward and the hoist cylinder positioned in the first stage, wherein the hoist cylinder is capable of raising in two stages, wherein stage one requires lower hydraulic pressure than stage two. Stage two can comprise a lower bore hydraulic cylinder than stage one. In yet other embodiments, safety systems of the invention require the hoist to always be raised to the second stage of the hoist cylinder for a traverse to operate in either direction. In other embodiments, safety systems of the invention require the forks to be fully swung out to operate the hoist up function, but the hoist down function is independent of other component locations or sensors for operation, and may rely on gravity.
[0063] The description of the invention includes exemplary apparatus, methods, techniques, and / or steps that are provided for illustrative purposes. However, it is understood that the invention may be practiced with additional embodiments and modifications as understood by one in the pertinent field.
[0064] Example 1Attorney Docket No. 23749836
[0065] A vehicle-mounted device is powered from a small gas engine so that it can operate while an attached truck’s engine is not running. The gas engine powers a hydraulic pump which provides power to all functions. A hydraulic motor is used for the traverse function of the carriage and drives a reduction gearbox. The gearbox output turns a sprocket that engages with a track or roller chain along the length of the chassis. A small hydraulic cylinder engages a pin that locks a traverse carriage in its position as shown in FIG. 8. Hydraulic cylinders are used to move the jacks, swing the forks, and lift the forks. The cylinder for lifting the forks on the mast is a one-way (single-acting) two-stage cylinder; it lowers by gravity, allowing oil in the bore end of the cylinder to flow back into a hydraulic tank.
[0066] Example 2
[0067] The emergency stop signal originates at an “I” terminal of the panel engine start switch as a wire (1) and then enters a switch and exits through another wire (2). The signal through the exiting wire (2) provides power to a wired pendant, entering at the pendant’s emergency stop switch and exiting as yet another wire (3). The signal proceeds through this other wire (3), then enters a left emergency stop switch and exits through another new wire (4). The signal from this new wire (4) enters a common terminal of a wired relay. The coil for the wired relay is energized by another wire (5) which has two wired sources. When the wireless pendant was not used, the wireless pendant enable switch is set to off, preventing power to the wireless receiver and switching the power to the wire (5) that energizes the coil for the first relay. To use the wireless control pendant, the wireless pendant enable switch is set to on. Power is then supplied to the wireless antenna that produces an output to a pin where a wire is connected that energizes the coil for the relay. When the wireless pendant is turned off, goes out of range, or the emergency stop button is pressed, the antenna output operating between the wireless points is deAttorney Docket No. 23749836 energized and the coil for the relay is not powered, and an emergency stop is activated by breaking the emergency stop signal. As long as none of the emergency stop buttons or conditions are triggered, power passes through the circuit and energizes a coil for the first relay, a relay providing ignition to the gas engine when energized, a relay providing power to the switches, and relays that control a hydraulic valve solenoid, an engine fuel cutoff solenoid, and a carriage lock or its cylinder valve. When an emergency stop is triggered, all of these relays deactivate, causing deactivation of the gas engine ignition, fuel cutoff solenoid, and all hydraulic functions. When the carriage lock cylinder valve is de-energized, the carriage lock cylinder loses oil pressure, and the cylinder spring causes the carriage lock to engage.
