INSTRUCTIONS,TELESCOPIC-TILTOVER LATTICE TOWERSBEFORE CARRYING OUT ANY WORK,READ ALL THE INSTRUCTIONS CAREFULLYIF IN DOUBT ASK.1。GENERAL DESCRIPTIONALTRON lattice towers are robustly constructed in modular sections of 15ft,4.57 M,overall length from quality heavy gauge steel tubeing,reinforced by a latticeof steel bracing rods.These are welded together using the electronically controlledMIG process and hot dip galvanized to BS729 for maximum weather durability.Thesections are based on a standard format and designed to telescope one inside theother to make up numerous combinations of tower to suit most applications.2.OPERATING PRINCIPLEThe ALTRON range of towers is made up of two types tower,those operated by a SINGLEwinch system,as the AT32/31 'mini tower'series and those operated by a Two winchsystem as the series 2 and comercial towers.SINGLE winch system."On the AT32/31'mini tower'series,the single winch systemis used for economy and carries out both the telescoping and luffing operationsas in the well proven ALTRON SM30 slimline mast.To carry out the tilt over operationusing a single winch,the two sections are locked together and the now fixed cablemerely operates as a luffing cable.Once the tower is locked in the upright positionthe sections are freed and the telescoping operation carried out in the normal wayusing the same winch.TWO winch system.On the larger towers the telescoping and luffing,tilt over,operations are carried out indipendantly by two seperate winch and cable systemsas shown in PIG 1.Where there are more than two sections,each additional sectionhas a seperate telescoping cable to operate it so that all the sections are thenextended or lowered in unison.The tilt over or luffing operation must only be carriedout with the sections FULLY LOWERED DOWN.3.FINISH.All the main components of ALPRON towers are protected by hot dip galvanizing toBS729 and the smaller parts are electro zinc plated.ALPRON products,manufactured exclusivly by Allweld Engineering,are purposedesigned and engineered to a high standard with every effort made to ensure Quality,Reliability,Versatility and Economy.4.ASSEMBLY.STANDARD TOWERS TWO WINCH OPERATION SINGLE WINCH AT32/31()1.On delivery,check the tower for damage or missing components againstthe parts list.Notify the carriers and Allweld Engineering in writingof any damage within three days of receipt.If there are any partsmissing,report the shortages to Allweld Engineering imediately.()2.Select the place where the tower is to be installed,making sure that thereis ample room for it to be lowered down with the aerials fitted.()3.Prepare the foundations needed for your tower to the required specificationwhich vary acording to the type of tower concerned.Soil conditions andthe structure of any walls intended to support the tower can vary so itis recomended that a local builder is consulted for guidence.Refer to DGo102
