DETAILED DESCRIPTION OF THE DRAWINGS

(11) The embodiments of the invention described herein are not intended to be exhaustive or to limit the invention to precise forms disclosed. Rather, the embodiments selected for description have been chosen to enable one skilled in the art to practice the invention.

(12) FIGS. 1-7 show exemplary embodiments of the disclosure in accordance with various embodiments of the invention. One embodiment can include an ESSLI system 1. The cover assembly 3 can be lifted using cover lift sling couplers 17, 17, 17, 17 disposed at lateral sides of upper corners of the cover assembly 3 at reinforced sections of the cover assembly 3 suitable for distributing weight of the ESSLI 1 system in sling lift operations. The exemplary ESSLI 1 major assemblies include a MMP 19 and a cover assembly 3 which mounts and seals to the MMP 19 to provide a protective enclosure for an equipment item, e.g., aircraft radar antenna, supported by the MMP 19 within the cover assembly 3. The MMP 19 includes a chassis 2 that is configured to receive, latch, (e.g. using thirty latches 12), and seal with the cover assembly 3. The MMP 19 also includes an equipment, e.g., antenna, lift station & frame support assembly (ALSFSA) 8 which is surrounded by and coupled to the chassis 2 using shock isolation mounts 21, 21, 21, 21 (see FIG. 2) (e.g., a rubber or elastomer material formed to dampen or isolate shock and vibration from the chassis 2 to the ALSFSA 8) disposed around the ALSFA 8. The ALSFSA 8 includes an equipment mount and lift assembly, e.g., an antenna mount and lift assembly (AMLA) 9.

(13) The MMP's 19 chassis assembly 2 includes a frame, chassis bottom wall piece 53, retractable caster assemblies 5, 5, 5, 5, removable leveling jacks 23, 23, 23, 23 (See FIG. 2) shown in a stowed position at two corners of the chassis assembly 2, a tow bar 11 with a retaining latch 11A (not shown but see FIG. 5), latches 12 (e.g. thirty latches surrounding the chassis assembly 2), and corner strap/chain tie down apertures 10, 10, 10, 10 (see FIG. 2) at corners of the chassis assembly 2 frame. The frame and chassis bottom wall piece 53 are sealed together at their junction points with a seal or fastening (e.g., welding) to provide protection from external environmental conditions such as moisture or dirt entering into the ESSLI 1 internal cavity. Retractable caster assemblies 5, 5, 5, 5 are attached to side sections of the chassis 2 in proximity to corner sections to enable movement on a supporting surface. The casters themselves in the retractable caster assemblies 5, 5, 5, 5 have a locking mechanism (not shown) to prevent rotation of a wheel in the caster assembly 5, 5, 5, 5. Chassis assembly 2 has a set of lower forklift slots 7, 7 formed in a mid-section of the chassis' 2 frame forming an aperture or elongated cavity through the chassis 2 from one side to another which is designed to receive forklift forks or tynes (e.g., cantilevered arms attached to a forklift load carriage that engage a load, e.g, the ESSLI 1). To permit a forklift to raise the ESSLI and maneuver it without damage to the chassis 2. Chassis 2 is coupled with the ALSFSA 8 at interior sections of the chassis assembly 2. Exemplary ALSFSA 8 includes the AMLA 9 that provides lift capabilities for the MMP 19.

(14) MMP 19 chassis assembly 2 is further formed with corner strap/chain tie-down apertures 10, 10, 10, 10 at corners of the chassis assembly 2, leveling Jack 11, cover-to-chassis latches 12 (e.g. thirty), and removable jack attachment structures 13, 13, 13, 13 positioned on external sides of the chassis assembly 2 frame near chassis assembly 2 corners. Once the ESSLI 1 has been positioned on a sufficiently hard or hard paved surface, retractable caster assemblies 5, 5, 5, 5 can be lowered and used to move the system 1 without the assistance of material handling equipment or can be towed via a tow bar 11.

(15) FIG. 2 shows various elements shown in FIG. 1 with a focus on an exemplary embodiment of the MMP 19 which shows an additional or more detailed view of the FIG. 1 MMP 19 as well as showing some additional or different features from the FIG. 1 MMP 19. For example, FIG. 2 shows a better view of how shock and vibration isolation mounts 21, 21, 21, 21 couple the ALSFA 8 and the chassis assembly 2 which isolate vibrations and shock between the chassis and the MMP 19. The shock and vibration isolation mounts 21, 21, 21, 21 protect or mitigate shock or vibration damage to an equipment item mounted within the ESSLI 1, e.g., radar antenna, that is mounted on the AMLA 9 from impact or shock damage caused by vibration or shock to the chassis assembly 2 or cover assembly 3. FIG. 2 also shows cover assembly guide stations (CAGS) 31,31, 31,31 which insert into holes formed in upper corner areas of the chassis assembly 2 that provides mechanical guidance and alignment for installing the cover assembly 3 onto the chassis assembly 2.

(16) The removable leveling jacks 23, 23, 23,23 include a jack section and a jack pad which spreads out force on a support surface and are shown in a stowed position The removable leveling jacks 23, 23, 23,23 are designed to be removed from their stowed position and installed on leveling jack attachment structures 13,13,1313 to provide an ability to level the MMP 19 as well as to permit three-axis movement of the equipment item positioned on the AMLA 9 to facilitate installation or removal of such an equipment item, e.g., radar antenna, from an end item such as an aircraft nose or radar attachment bulkhead. The lift jack, gear assembly, and handle 25 provides a capability for raising or lowering the equipment item mounted on the AMLA 9 and its antenna mount bracket 27 (see FIG. 3).

(17) FIG. 3 shows a drawing of an exemplary ALSFA 8 which attaches to the chassis assembly 2 of the overall MMP assembly 19. An antenna could be mounted on the antenna mount bracket 27 that is then further supported by frame support assembly (FSA) 45. Note the FSA 45 has a variety of support structures to include interconnecting lateral bracing structures 45A as well as diagonal vertical bracing structures 45B, 45B.

(18) FIG. 4 shows a perspective drawing of the exemplary ESSLI 1 such as, e.g., shown in FIGS. 1-3, fully assembled with the cover assembly 3 installed on the FIG. 2, 3 MMP 19. Cover assembly 3 is formed with cover assembly forklift slot frames 43 which are formed to accept the forklift forks or tynes and lift or move the cover assembly 3 off of the MMP 19 via material handling equipment, e.g., a forklift. Access to an interior of the cover assembly 3 can be done via one or more maintenance access cover assemblies or panel assemblies, e.g., 51, 51, or by lifting and removing the cover assembly 3. Removal of maintenance access panels or covers to these maintenance access cover or panel assemblies 51, 51 allow for easy access to some key components of the ESSLI 1 that help maintain preconfigured, desired conditions such a inspection or replacement of desiccant bags installed within the ESSLI 1 to dry an internal environment of the ESSLI 1. The cover assembly 3 can be formed to include a maintenance access aperture (not shown) formed into a wall of the cover assembly 3 that has the maintenance access cover or panel bolted onto the maintenance access aperture (forming the cover or panel assemblies 51, 51) to provide for maintenance personnel access into the ESSLI 1. The maintenance access panels are placed and coupled to the cover assembly 3 over the maintenance access aperture and secured to the cover assembly 3 via fasteners such as bolts. A seal or sealant (not shown) can be included in the cover or panel assemblies 51, 51 disposed between the maintenance access covers or panels along the perimeter of each of the maintenance access apertures. The seal or sealant can be configured to provide a barrier between an internal section of MMP 19 and an external environment (e.g., moisture or dirt). Additional features of the FIG. 4 embodiment include pressure relief valves 23 (three in this case) and a humidity indicator 20 which indicates via a color indication of humidity conditions of the internal environment of the ELSSI 1. Pressure relief valves 23 can be used in intermodal transportation activities such as, e.g., required for shipping of the ESSLI 1 using aircraft (not shown).

(19) FIG. 5 shows an end view of the FIGS. 1-5 ESSLI 1 showing the cover assembly 3 over the exemplary MMP 19 base. Another view is shown of one of the maintenance cover panels 51, the humidity indicator, 20, and the pressure relief valves 23 as well as the tow bar 11 with the retaining latch 11A. The humidity detector 20 can be inspected to show, e.g., a blue color, indicating a particular environmental condition within the ESSLI 1. If the humidity detector 20 indicates another color, e.g., pink, such an indication can show, e.g., desiccant drying bags require replacement within the system 1

(20) FIG. 6 shows a closer view of one of the exemplary retractable caster assemblies, e.g., 5, that can be lowered or raised by removal of a locking clip 33 and pulling a caster assembly position locking pin 34 (a separate pin for each assembly) out of retracted position pin holes 61A in lateral retractable caster assembly frame 67 mounted to the chassis 2 and pivoting the caster assembly 5 to align with another hole set (extended pin holes 61B) in the lateral retractable caster assembly frame 67 extending from the chassis assembly 2 so the caster assembly 5 is lowered so it extends below the chassis assembly 2. The lowered caster assembly 5 thus permits movement on the hard or paved surface in a maneuver position. A pivot pin and locking clip assembly 37 permits the caster assembly 5, e.g., to pivot and acts as a hinge type structure as well as being able to support the caster assembly 5 in the extended position (e.g. carrying distributed weight of the ESSLI 1 and enabling movement.

(21) FIG. 7 shows a view of the cover assembly 3 being lifted into position for lowering on the MMP 19 by a forklift with its forks or tynes engaged and inserted into the cover assembly forklift slot frames 43.

(22) FIG. 8 outlines a method of using the ESSLI 1, which can include: step 201: providing the ESSLI 1 and lowering the caster assemblies 5, 5, 5, 5 into the extended position and locking them into position using the caster assembly locking pins 34 inserted into the extended pin holes 61B for each assembly 5. Step 203: removing the cover assembly 3 from the MMP 19 using material handling equipment, such as a forklift inserting forklift forks or tynes into the Cover Assembly Forklift Slot Frame 43 or using a crane coupled to the ESSLI 1 via the cover lift sling couplers 17, 17, 17, 17, and positioning the MMP 19 under an end item, e.g., an aircraft fuselage nose section, using the caster assemblies 5, 5, 5, 5 in the extended configuration. Step 205: If required due to support surface condition (e.g. not level), a next step can include removing the removable leveling jacks 23, 23, 23, 23 from their stowed position attached to the chassis 2 and installing them on the leveling jack attachment structures 13,13,1313 to provide an ability to adjustably level the MMP 19 as well as to permit three-axis movement of the equipment item positioned on the AMLA 9 to facilitate installation or removal of such an equipment item, e.g., radar antenna, from the end item such as the aircraft nose or radar attachment bulkhead. Step 207: operating the lift jack, gear assembly, and handle 25 to raise or lower the antenna mounted on the AMLA 9 and its antenna mount bracket 27 to position the antenna mount bracket 27 in contact with the antenna then, if required, adjusting the leveling jacks 23, 23, 23,23 and/or the AMLA 9 height to mate the antenna mount bracket 27 with a connection point on the antenna then installing antenna mount bracket 27 hardware to couple the antenna mount bracket 27 with the antenna. At step 209, removing antenna-to-end-item mounting hardware and other connections (e.g. electrical wiring, cooling connections, etc) and lowering the antenna using the AMLA 9 and the lift jack, gear assembly, and handle 25 to a lowered or stowed position on the MMP 19. At step 211, repositioning the MMP 19 laterally using the caster assemblies 5, 5, 5, 5, repositioning and lowering the cover assembly onto the MMP 19, and latching the latches 12 to the cover assembly 3. At step 213, the ESSLI 1 can be positioned into a storage mode to include ensuring, e.g., desiccant bags, are positioned in the ESSLI 1 and the ESSLI is configured, if required, for mitigating undesirable internal environmental conditions through, e.g., leveling via the leveling jacks 23, 23, 23,23 on a support surface. At step 215, a loading process can include loading the ESSLI 1 onto a truck, aircraft, or rail intermodal system using material handling equipment, e.g., a forklift engaging its tynes or forks into forklift slots 7, 7 or a crane and sling coupled to cover lift sling couplers 17, 17, 17, 17. At step 217, securing the ESSLI 1 to the intermodal system equipment, e.g., truck, rail car, or aircraft load bed, using at least strap/chain tie downs coupling the corner strap/chain tie-down apertures 10, 10, 10, 10 with the intermodal system equipment. At step 219, transporting the ESSLI 1 to a predetermined destination location. If required, step 213 can be repeated at the predetermined destination location.

(23) For installation of an equipment item stored in the ESSLI 1, an installation process can include that which is outlined in FIG. 9: step 301: providing the ESSLI 1 with the equipment item contained therein mounted on the antenna mount 27 and lowering the caster assemblies 5, 5, 5, 5 into the extended position and locking them into position using the caster assembly locking pins 34 inserted into the extended pin holes 61B for each assembly 5. Step 303: removing the cover assembly 3 from the MMP 19 using material handling equipment, such as a forklift inserting forklift forks or tynes into the Cover Assembly Forklift Slot Frame 43 or using a crane coupled to the ESSLI 1 via the cover lift sling couplers 17, 17, 17, 17, and positioning the MMP 19 under an end item, e.g., an aircraft fuselage nose section, using the caster assemblies 5, 5, 5, 5 in the extended configuration. Step 305: If required due to support surface condition (e.g. not level), a next step can include removing the removable leveling jacks 23, 23, 23, 23 from their stowed position attached to the chassis 2 and installing them on the leveling jack attachment structures 13,13,1313 to provide an ability to adjustably level the MMP 19 as well as to permit three-axis movement of the equipment item positioned on the AMLA 9 to facilitate installation of such an equipment item, e.g., radar antenna, from the end item such as the aircraft nose or radar attachment bulkhead. Step 307: operating the lift jack, gear assembly, and handle 25 to raise or lower the antenna mounted on the AMLA 9 and its antenna mount bracket 27 to position the equipment item in relation to the end item's equipment item mating and mounting structures (e.g., the antenna's mounting structures on the aircraft) then, if required, adjusting the leveling jacks 23, 23, 23, 23 and/or the AMLA 9 height to further align end item mounting hardware with the end item's mating and mounting structures then mounting the end item on the end item's mating and mounting structure with end item mounting equipment. At step 309, removing antenna mount bracket's 27 mounting hardware to the end item, e.g. antenna, and lowering the AMLA 9 using the lift jack, gear assembly, and handle 25 to a lowered or stowed position on the MMP 19. At step 311, repositioning the MMP 19 laterally using the caster assemblies 5, 5, 5, 5, repositioning and lowering the cover assembly onto the MMP 19, and latching the latches 12 to the cover assembly 3.

(24) One exemplary embodiment of the invention is configured with structure and materials configured to enable the antenna lift station and frame support assembly 8 with a load limit of four hundred pound antenna. Alternatively, cover lift sling couplers 17, 17, 17, 17 can be used to raise or lower the cover assembly 3. The cover assembly guide stanchions 31, 31, 31, 31 guide the cover assembly 3 onto the MMP 19 to ensure the cover assembly 3 is properly aligned to the chassis 2 and further aids in ensuring the cover assembly 3 is sealed against environmental conditions after latches 12 are latched to the chassis assembly 2.

(25) Embodiments of the ESSLI 1 can be stored in different configurations depending on environmental conditions. The caster assemblies 5, 5, 5, 5 can be stored in the extended and maneuverable position or retracted for intermodal transportation or sitting directly on a support surface. Alternatively if environmental conditions (e.g., wet, cold, uneven surface, wide temperature variations that require even cooling/heating throughout the ESSLI 1) require, the ESSLI 1 can be stored so that the leveling jacks 23, 23, 23,23 can used, e.g., to keep the ESSLI 1 elevated so that environmental conditions inside the interior of the system 1 can be more equalized with ambient temperature.

(26) Although the invention has been described in detail with reference to certain preferred embodiments, variations and modifications exist within the spirit and scope of the invention as described and defined in the following claims.
