Continuous operation in water requires special considerations in order to combat the impact of chain operation in corrosive environments. The Ivanhoe water ride series chain has been developed to enhance performance in this challenging environment to overcome the impact of corrosion, chain seizure and component wear.
In considering constant exposure to water with chemical addition for algal control, corrosion is an issue on water ride chains. With the benefit of long experience Precision chains has developed a dual process surface treatment to increase corrosion resistance. The zinc based high integrity coating offers superior protection combined with PC802 topcoat designed to enhance the anticorrosion properties of trivalent chromium passivates on zinc and zinc alloys in submerged water environments. Even when the coating is penetrated, the treatment continues to offer superior corrosion resistance.
The challenging environment encountered in Transfer and Lift chain on rides can create pin and bush seizure which in turn significantly shortens the life of the chain. Long experience has seen the development of a polymeric sleeve to act as a low friction and lubrication free bearing element thus eliminating metal to metal contact.
The water ride chains conform to British Standard series BS4116 which has traditionally employed a thin walled bush. Recognising that the component could be improved Precision Chains have introduced a heavy wall bush design which overcomes premature wear and failure.
