The Tip Barrow is the equivalent of a wheel barrow except it is designed for the height of a Jumbo MK2 and Jumbo MK3 brick machine. The contents are tipped into the bin of the brick making machine and returns to collect more mixture while the machine continues production. The JSB is also at a height suitable for the Doubell Panmixer, which ejects a concrete mix (aggregate + cement). Two are optimal for the MK2 and three for the MK3. A static machine will not require a tip barrow since the mixture is ejected from the panmixer into a chute which feeds into the bin.
