"WANANCHI" OX-CART

DEVELOPED BY: Originally designed by Rev. V. Swenson of Singida Mission and later developed further at T.A.M.T.O., Tanzania.

DESCRIPTION; Built to carry a load of 1400 lbs. (656 kg), pulled by two oxen. An important design feature of this cart is the woodblock axle bearings, each made of two pieces of wood, oil-impregnated by soaking in hot oil, the axle bearing hole of

(38) diameter being drilled centrally through the blocks. This bearing design facilitates ease of maintenance and renewal of the bearings by carpenters in rural areas.

Each of the wheel assemblies is an integral unit, the wheel spokes welded to the axle shaft.

Note; Figures in brackets are in millimetres.
