We’re looking for ISO type shelters that we can mount on one of our antennas to house electronics and chiller cooling systems.  The shelters will have the unique requirements of rotating with the antenna on two axes both horizontal to the ground and vertical to the ground.  This requires the shelter and its contents to support tipping over on its side.  A list of basic specifications and drawings describing the rotation are below.
Two shelters required per antenna to house 6 racks of electronics, AC power distribution, and chiller cooling equipment
Specifications:
Size: Approx 20 ft length x 12 ft width x 9 ft height
Material:  Steel or aluminum frame with insulated fiberglass walls and ceiling
Color:  White
Weight: TBD by design
Flooring: Steel or aluminum frame capable of supporting 6 x 300 lb racks
Rotation:  Both shelters will be mounted to the sidearms of the antenna 50 ft off of the ground and will rotate with the antenna on two orthogonal axes
Elevation Axis:  horizontal axis parallel to ground where the shelter short face rotates end-over-end.  If a person were in the shelter during this motion they would fall into the short face.  The velocity of rotation is 3 degs/sec and the acceleration is 3 degs/sec^2.
Azimuth Axis: vertical axis perpendicular to ground where the shelter spins like a carousel. The velocity of rotation is 3 degs/sec and the acceleration is 3 degs/sec^2.
 
Doors: 2 on one side (see figure below)
3 ft width x 6 ft 8 in height
Industrial hydraulic closer
Rain drip shield above
Pad-lockable
Lighting: LED overhead interior; LED exterior over door
Light switch: 2; one for each doorway
Outlets:  6 dual NEMA 5020R GFCI weatherproof outlets, 120 VAC
Power distribution panel:  100A main, 10 circuit, single phase
Surge Protection Device: Type 2 MOV, 100kA, 120 VAC
Proximity sensors: 6 interior 24 VDC sensors to detect full coverage indoors
Floor drainage: water channels in floor leading to drain holes in short walls
