Collapsible columns with hand balances system

Description

Collapsible columns with hand balances system, are mainly suitable to light sport areas or large areas, with height form 8 up to 20m and a limited number of floodlights.
They are a good solution in areas which are  difficult to.
With its simple operating system, they allow mainteinance of floodlights safely at ground.

Conical column with octagonal or polygonal cross section, collapsible with hand balances system, manufactured under certified quality check according to  ISO9001 by authorized processing center according to DM 14/01/08, obtained by cold forming of trapezium of pressed steel plate and subsequent external longitudinal welding carried out by approved automatic process (submerged arc) and welding check according to EN ISO 3834.
Completed with hinge, counterbalance designed according to the load on top, cable, driving pulley. Movement can be carried out without effort and danger, provided that the stated minimum and maximum weights   are respected; in fact pivoting is made thanks to gravity balanced between the weight of the floodlights on one end and the counterbalance on the other. The operator has just to check following the movement with the cable. The system with cable and driving pulley allow to increase the weight to be installed on top, keeping the operator’s effort within the safety standard. 

Protection against corrosion by means of hot dip galvanisation obtained with the following cycle: degreasing; pickling, washing, fluxing, pre heating; hot dip galvanization in melted zinc bath at 440÷450°, with minimum percentage of zinc into the bath ³ 98.5%. Coating obtained according to UNI EN ISO 1461 with minimum thickness 55 microns et average 70 microns.

External painting, if any, with colour from our colour card, rough effect, obtained with thermosetting powders cycle including: cleaning from zinc coating burs; smoothing of the surfaces by means of a light mechanic device; cleaning of the surfaces in order to eliminate grease or dirty and create a good adherence base; application by means of electrostatic spray of polyester powder suitable for galvanized surfaces for outside installation, in order to reach  60/80 micron thickness; polymerization into oven at constant temperature of approx. 200° for 40-50 minutes, package for each column, by banding with tissue 100% polyester, (no pluriball), in order to avoid damages during the handling phase. The characteristics of the obtained coat will be: average thickness  60 micron, resistance to checkering test  ISO2409, resistance to crash test to UNI8901

The columns will be CE marked according to the standard in force  (DPR246/93, 89/106/CEE; 93/68/CEE). The label on each column must quote: standard reference  EN40-5, manufacturer’s identification, certificate number of the authorization to the mark CE CPD P029,  year of marking, product code, and order number reference

To design lighting column You need to know the following data:
– design wind speed
– features of the surrounding landscape that is ground roughness category 
– height  up to the lighting source 
– number, type, dimensions and weight of the fixture to be installed 
– fixture arrangement  (post top; or brackets)

Standard

Columns, provided to be fixed to the basement by direct burying, are completed of the 3 works for electric wiring at base, cable entry slot, earth device, slot for junction box

The maximum weight which can be installed on top is meant with movement by means of rope and driving pulley.
In order to choose the suitable model You need to know: height up to the lighting source ; arrangement (post top or with bracket, …), number and type of lighting fixture to be installed; installation site.
