• Transfer house and feed conveyors to existing staithes facility at Harton on the River Tyne. • The pipe conveyor belt to have a minimum life of 4 years, idlers and rollers to meet British Coal design life standards of 26,000 and 50,000 hours. Chute wear rate to be guaranteed for 4 years.
CONVEYOR PERFORMANCE These conveyors are not the first to use such wide idler spaces successfully. CDI designed the 15.3km Zisco Conveyor for Zimbabwe Iron and Steel Company with 5 x 10m spacing, and the British Coal Board owned Selby incline conveyor used 5m carry spaces from the 1980s. Wide idler spacing should not however be used irresponsibly.
