Modular, reusable transmission tower systems

ERS with Lindsey

The leading choice of utilities around the world, Lindsey Emergency Restoration System (ERS) structures are designed to rapidly bypass permanent transmission towers at any voltage in any terrain. Lindsey ERS can be erected in hours and are suitable for hand, crane, and helicopter installation methods.

Though designed for temporary use, many utilities have kept Lindsey towers in continuous service for over a decade and counting because of their robust design.

Terrain Conquered

Lindsey ERS have been used in practically every terrain found around the world.

Lindsey ERS structures support mountain-to-mountain spans in the Himalayas, EHV lines crossing the hot, hard-packed sands of the Middle East, and in the soft-soiled flood plains and estuaries of Southeast Asia.

Flat, hilly, or mountainous terrain? Loose, rocky, hard-packed or marshy soils? Lindsey’s ERS engineering team can work with you to determine the best gimbaled structure design, and the most appropriate foundation bases, anchor types and installation methods for your system. Have the confidence that Lindsey ERS can conquer your terrain.

An Essential Part of Grid Resiliency

Damage is Always Unplanned

Storms, soil erosion, ice, earthquakes, flooding and willful acts all can damage or destroy towers. Lightweight Lindsey ERS structures are designed to rapidly get lines back in service. By quickly and safely bypassing damaged permanent structures, ERS structures allow you to rebuild or replace the permanent structures without time constraints.

Support during Construction and Maintenance

Lindsey ERS structures have been used to bypass transmission lines around towers or entire substations that are under construction or being maintained, replaced, or expanded.


Lindsey ERS structures have been the leading choice of utilities for decades to provide for unscheduled tower restoration and scheduled construction.

Versatility is our Hallmark

Lindsey ERS structures are completely modular and reusable. All system components can be used to configure dead-end, running angle, tangent, herringbone, and chainette structures. Requiring no special foundation, suitable for any soil, and capable for use at any voltage, AC or DC, Lindsey ERS structures provide the ultimate in flexibility.

Lineman Safe and Lineman Friendly

Lineman safety and convenience are built in to every Lindsey ERS. Compatible with all commercially-available fall arrest systems, linemen feel safe using familiar gear. Wide, comfortable footing means confident climbing, supporting as many as 4 workers at the same level. A variety of platforms, lifts, hoists, and other accessories simplify and speed installation. Lindsey ERS structures use only permanent anchors for safety during construction.

Four LINDSEY Models

1070-Series ERS

The Gold Standard

Our 1070-Series ERS are fully compliant with the design, testing, AND dimensional requirements of IEEE Standard 1070-2006, “Guide for the Design and Testing of Transmission Modular Restoration Structural Components”.

Size: 2.4 MB

600L-Series ERS

Compact and Light

When lightweight and compact storage are paramount, Lindsey 600L-Series ERS are the solution. Physically the lightest ERS system on the market, this ERS is ideal when carrying the ERS system components by hand in the field is expected. While light in weight, the 600L-Series still has almost twice the buckling strength of other non-fully IEEE Std. 1070 compliant ERS systems. All 600L-Series components, including column structure segments, fit neatly into standard 20-foot shipping containers, making for compact storage and security of inventory.

Size: 3.4 MB

600H-Series ERS

Compact and Tough

Almost identical to the 600L-Series, the 600H-Series uses larger structural elements for greater buckling strength, while still being easy to transport by hand and store. The 600H achieves 90% of the 1070-Series rigidity while still providing for compact storage. All 600H-Series components, including column structure segments, fit neatly into standard 20 foot shipping containers, making for compact storage and security of inventory.

Size: 3 MB

800-Series ERS

For Very Heavy Loads and/or Helicopter Assembly

The 800-Series is designed to support the heaviest, most-challenging conductor loads with ease. Designed for lines spanning the French Alps, the 800-Series has 3 times the critical buckling load capacity of our popular 600L-Series, and twice that of the 1070-Series. While all ERS towers can be installed by helicopter, the 800-Series allows for assembly by helicopter, with a unique optional alignment and centering frame designed to assist helicopter pilots in landing tower sections on top of foundations or already installed tower sections. Like Lindsey’s 600L- and 600H-Series ERS structures, the 800-Series is export friendly, easily fitting into standard shipping containers
