Hot-dip galvanizing

When steel is dipped into molten zinc at a temperature of approximately 450 °C, a layer of iron-zinc alloy builds up on the steel component as a result of inter-diffusion between the liquid zinc and the steel surface.

     
 

Transport

Moving the Hot-dip galvanizd HEB260. Because it has been raining the last few weeks, heavy machinery is forbidden onto the lawn...

Therefore inventiveness manpower

     
 

Poles

Using wooden poles to move the HEB's

     
  Lifting

Using the chain hoist for lifting the iron parts onto the rotorbase.
     
 

Slowly

The wooden plate is to prevent damage and will smoothly slide the beam along the rotor.

     
 

Parts

Four beams will be screwed together to compose the tower base plate.

     
 

Grease

Using grease underneath the beams forms a thin layer.

     
 

Slide

Grease also makes sliding easier...

     
 

Last parts

Moving cross the lawn...

     
 

Detail

Wooden poles and on top of the rotor.

Bolts

Secure the towerbase with:
26x M24x80 (8.8) bolts.
The frame using 16x M20x80 bolts

Using off-shore grease to smear the bolts.

Fixed with M24 @ the rotor base

     
 

Spacer

The first tower section will be placed onto these spacers,

     
 

Marker

After dipped into molten zinc the drill holes can be places exactly onto the base using marking stripes...
