The TROK trailer was modified from a standard no braked trailer. The sides were built up using thin ply that was protected with Ronseal exterior wood stain (many coats). This has lasted for years without any degredation.

The walls are held in place with 2 inch aluminium angle. The walls are bolted to teh angle with M6 roofing bolts and repair washers. Brown sealant was used ebtween the aluminium and the plywood panels.

The rear door hinges down and is made of 3/4 inch quality plywood. It is reinforced at the edges with a welded 1 inch steel angle frame. This is painted with silver Hamerite paint.

The rear of the trailer has two drop legs. The telescope rocker and mirror box are wheeled into the trailer with the aid of a hand winch that is bolted to the A frame of the trailer at the front. A hole in the front panel allows the winch strap and hook to pass through. An eyebolt is supplied in the front of the rocker box to hook the winch to.

The 3 x 20Kg counter weights sit on the floor of teh trailer. The top box then sits on top of teh counterwights with some protection. Old sleeping bags are used to protect the finish.

There are white and red lights fitted inside the trailer along with a 12V outlet for additional power.

Wrachet straps are used to hold down each section of the telescope to the floor of the trailer during transport. A crossbar is used to prevent the rocket box moving also. This is held in place with some wingnuts to the floor of the trailer.

The truss poles and ladder are mounted on the roof rack.

We can normaly remove the telescope and have it set up within 20 minutes.
