Cargo loading trailer
A cargo loading system for loading freight into or out of the cargo hold, the system comprising: a tilt control means which can be actuated by control signals in such a way that variances in tilt of a palletized load can be immediately righted; a control panel for actuation by personnel; a power source to the control panel; and a trailer base connected to the tilt control means for accepting freight.
1. A cargo loading system for loading freight into or out of the cargo hold, the system comprising:
a trailer base sized to secure a pallet adapted to hold an AFFS unit;
a plurality of support legs affixed to said trailer base in spaced relationship in fore and aft locations thereon;
a plurality of steerable casters, each caster operatively coupled to a corresponding support leg of the plurality of support legs such that each casters can rotate about an axis of rotation perpendicular to the ground,
a first set of hydraulic actuators coupled to the plurality of support legs to displace the plurality of casters from a stored orientation in which the casters are not in contact with the ground to a deployed orientation in which the castors contact the ground to raise the trailer base to a desired height;
a second set of hydraulic actuators coupled to the plurality of casters to control the rotation of each caster about the axis of rotation for steerable control thereof; and
a control panel assembly coupled to the trailer base and in operative communication with the first set and the second set of hydraulic actuators to provide a single point of control for height adjustment and steering capability of said casters by personnel, the control panel assembly having tilt control switches in operative communication to maintain horizontal and vertical alignment of the trailer base during height adjustment of the trailer base by vertical articulation of said casters.
2. The cargo loading system of claim 1 , wherein the tilt switches utilizes unidirectional and bi-directional open collector outputs.
3. The cargo loading system of claim 2 , wherein the tilt switch is a non-mercury, single axis, programmable tilt switch.
4. The cargo loading system of claim 1 , wherein the control panel assembly further comprises a safety cut off switch system, activated manually or automatically by a tip-over protection warning system.
5. The cargo loading system of claim 1 , wherein the cargo hold is for an aircraft.
6. The cargo loading system of claim 5 , wherein the aircraft is a rear loading aircraft.
7. The cargo loading system of claim 1 , wherein the trailer base has a length of at least about 551 inches.
8. The cargo loading system of claim 1 , wherein the plurality of support legs include two support legs affixed in fore locations to said trailer base and two support legs affixed in aft locations to said trailer base.
9. The cargo loading system of claim 8 , wherein the plurality of steerable casters include two steerable casters, each coupled to a corresponding support legs of the two support legs affixed in the fore locations to said trailer base.
10. The cargo loading system of claim 8 , wherein the plurality of steerable casters include two steerable casters, each coupled to a corresponding support legs of the two support legs affixed in the aft locations to said trailer base.
