PORTABLE TOWER MANUFACTURING
Patented portable towers for container shipping all sizes, on skids or wheels “size 20’/6M – 250’/76.2M Rapid Deployment portable tower solutions handling multiple large microwave dishes on portable towers designed to meet your immediate needs.
Towers can be permanent on the skid mounts with auto-leveling systems, container shippable, or our flagship roll on roll off with expandable deck platform working areas.
Trusted and contracted with the US Government GSA advantage program.
US DOD Missile Defense Systems Quote: LMS Tower is the only one that meets all the critical requirements pursuant to analysis and comparison/evaluation, LMS robust design and larger deployed footprint provides 105 mph wind resistance capability on the launch pad. Oil and Gas Alberta Canada: Where undisturbed grounds are a priority LMS mobile tower trailers are a perfect fit. For quality stable microwave path alignment they rely on Landa reliability.
LMS NEVER FAIL LATTICE TOWER KEY SYSTEM INCLUDED: LMS key system. Both Tilt and Erection Systems are designed with redundant systems utilizing LMS fail-safe key and hand cordless drill, impact or custom hand tool in case of no power, etc. Hydraulic units have an optional hand pump for redundant backup as well Towers are 100% true emergency field unit.
The only authorized GSA government-contracted provider of this product in the USA.
The real-world experience and deployments of the Landa Mobile Systems towers have proven themselves in all climates and conditions to meet or exceed the MIL-STD-810G standards. We warrant our lattice and tilt-up crank towers under our warranty to meet or exceed the below. Landa Mobile Systems lattice products under gov’t (Navy) acquisition rules worked through the approval testing process, by their acceptance testing standards. BAE imposed additional gov’t required Acceptance Test Procedure which mandated they test every aspect of the tower system with us as a witness before we would accept it (which, having gone through one with them, BAE quote led buyer “I would recommend for anyone, commercial or government.”
US Department of Commerce, Bureau of Industry and Security approved exportable goods.

For each tower deployment the location of the COW, location of guy cables, quantity of guy cables, coaxial cables, specific antenna loading, and antenna elevation are all very critical factors in determining the specifics of that tower. Therefore, we analyze each specific COW deployment based on the above criteria to determine it‘s feasibility. The TIA-222-G uses the following factors that are considered in the design wind pressure of these towers.
- Structure Class: Used to determine the important factor for the structure based on the hazard to human life, property damage, and the necessity of essential services.
- Exposure Category: An exposure category that adequately reflects the characteristics of ground surface irregularities at the site shall be determined. An account shall be taken of variations in ground surface roughness from natural topography, vegetation as well as from man-made / constructed features.
- Topographic Category: A factor to consider wind speed-up at isolated hills, ridges, and escarpments constituting abrupt changes in the general topography.
- Wind Speed: The basic wind speed and ice thickness shall be at a minimum per the IBC wind maps and shall be considered to come from any horizontal direction.
- Gust Effect Factors: Factors that account for the effects of wind gusting and the calculated response of a tower type structure.
- Load Combinations: Used to determine the “timing” or combinations of loads on the structure at the same time per the 2012 IBC.
- Maximum angle of terrain in degrees for safe trailer deployment up to 7 degrees side to side, 3.5 degrees front to back without additional blocking.
- With this being said, there are no easy copy/paste answers. If you have a specific set of criteria we can analyze that as a baseline to help create an understanding of the COW’s feasibility.
- Providing clients detailed pertinent design information with exhaustive wind load reports and specific guying requirements for each install while maintaining Landa proprietary design drawings and calculations.
- Certified TAA Compliant supplier
