When a disaster strikes, temporary towers are used to restore power quickly, while the permanent towers are replaced.EMERGENCY RESTORATION

When line maintenance is required, temporary towers are used to keep power flowing, without the need to commit expensive equipment.REGULAR MAINTENANCE

THE EVOLUTION OF TEMPORARY TOWERSIn the beginning the Aluminum Lattice Tower.

The first generation of emergency tower was developed in the 1970s as an aluminum lattice type. This technology satisfied transmission requirements at that time.

Then, the Modular Aluminum Tower

In 1990, the first modular aluminum type tower was introduced.This second generation design solved many of the shortcomings of the aluminum lattice tower.THE EVOLUTION OF TEMPORARY TOWERS

And today, the Advanced Modular Aluminum TowerIn 2002, the Advanced Modular Tower was introduced by Tower Solutions Inc. The new design meets all the TL challenges of the 21st century and beyond such as 765 kV, 198 kmph wind and 600m span.This new tower is a significant improvement, setting the new standard.THE EVOLUTION OF TEMPORARY TOWERS

Faster and easier installationEasier to store and transportCan be erected in any terrainHigher strength to weight ratioUses standard nuts and boltsFewer components and more adaptableSpecial foundation not requiredMaintenance freeAdaptable to any configurationBase articulation has low friction surfaceAttachment plate has 2 degrees of freedomADVANTAGES OF THE NEW TOWER

UNIVERSAL ATTACHMENT FOUNDATIONMAST SECTIONARTICULATIONCOMPONENTSOF THE ADVANCED MODULAR TYPE TOWER GIN POLE

Very small footprint Uses standard nuts and boltsDesigned for balanced load distributionCan be expanded for soft soilsThe FoundationCOMPONENTS

Allows free rotation in all directionsTower can be orientated in any direction, without limitBronze alloy components reduce friction to a minimumMakes it easy to erect the towerEvenly distributed loadCOMPONENTSThe Articulation

High strength-to-weight ratioModular square design allows easy erectionPatented hole design maximizes strength and minimizes wind resistance and weightHardware components are interchangeableOptimal fit for storage in shipping container Ends machined to tight tolerance to eliminate alignment problemsVery high area of contact at section endsCorner rail in each corner gives unrestricted sliding movement for gin pole and fall arrestor COMPONENTSThe Mast Section

A single attachment is used for both guywires and insulatorsTwo degrees of freedom means conductor movement is not transmitted to towerMade of only 4 parts, making assembly and installation easy

Transfer rods distribute load evenly to towerCOMPONENTSUniversal Attachment Plate

For lifting tower sections, insulators and other tower componentsCan be operated without heavy equipmentEasily attached to the tower sectionHigh strength to weight ratioSlides independent of lineman safety devices

COMPONENTSGin Pole

Keeps the line worker safely attached to the towerRemains attached to the tower at all timesNever disconnects from the towerTravels freely upward, but will not move down until you want it toOut of the way while climbing the towerSPECIAL TOOLSFall Arrestor

Gives the lineman a place to rest when working on the tower.Lightweight and durable.Securely attached to tower but easy to move when needed.

SPECIAL TOOLSLinemans Step

Capstan WinchGasoline powered winchSpecial braking system prevents uncontrolled releaseSimple operationIEC certifiedSPECIAL TOOLS

Helicopter Centering ToolEasy to useMakes it easy for a helicopter to drop the upper tower sections onto the lower sectionSPECIAL TOOLS

CraneCan be used with short or long end to lift up to 2000 Kg weight.Using a temporary tower as the crane, a permanent steel tower can be erected without the expense of a crane or helicopter.SPECIAL TOOLS

Linemans PlatformExtendible to 12 outreach from the towerLightweight and durableEasy to installVersatile and adaptable to any orientationSPECIAL TOOLS
