The trailer in essence is the foundation of your tiny home, it carries the full weight of your home and contents AND makes it portable rendering it NOT a house but a vehicle!
To immerse myself further into the design I have decided to design and build the trailer as part of the project. Tinka Design will complete the design engineering and the build will be done by a good friend of mine Craig Baker who has many years’ experience as a welder building large agricultural farming equipment. Together Craig and I will cut, weld and assemble the trailer using a farm shed down in Geraldine, a 2 hour drive south of Christchurch.
The trailer design has taken some time and has been a steep learning curve to understand all the necessary components, the brands, price points and benefits. I have chosen to purchase my trailer components from CM trailers based in Ashburton, New Zealand. They have a distributor close by the work office which has allowed viewing the components and discussing issues as they come up very easy without wasting valuable time.
The basic layout of the chassis consists of 2 125 x 75 RHS beams that run the length of the trailer. These are held apart by the joists (63 x 35 RHS) placed at 600mm centres to allow a ply floor to fasten down directly onto the steel. 100 x 50 Duragalv C-Channel runs the perimeter of the trailer so that the frame can be easily bolted to the trailer base.
The overall dimensions of the trailer are as follows:
Width: 2.4m frame width, 2.5m overall width including the mud guards.
Wheels: 14 inch 8 ply – rated to 850Kg per wheel.
Weight: 720 – 800KG (a final weight will be confirmed once the trailer is fully assembled)
Being responsible for all aspects of the trailer, from design, part selection to ordering of steel has proven to be a great challenge allowing me to understand each design decision and know where the money is being spent.
