Sheep snooze under the mobile shelter while others eat in the August sunshine.
The mobile shelter has weathered 100 mph winds without any sign of overturning. The rear axle has been extended to three metres (about 10 feet) by cutting the original axle in half and welding a new middle. The diagonal steel supports from axle ends increase rigidity in the steel frame.
Fifty mm (two inch) square tubing holds two beams that support the trusses. The tubing is welded to the front axle made from a former antique hay wagon. The wagon frame has plywood and boards attached to prevent sheep from getting injured. The tires are recycled from cars. The bungee cord is used to secure the tongue when the shelter is parked for the day.
The standard roof trusses are 5 metres (16 feet) long and placed 60 cm apart (two feet) on beams made of 2 by 6 inch boards. A plywood underlay for the roof maintains rigidity while the sheet metal roof protects the sheep from rain, sun or severe wind. The two metre (7 feet) height from ground to trusses allows the shelter to pass over fence posts and human heads safely.
