Iron and steel scrap handling is special case requiring a combination of lifting technologies and very careful analysis to ensure a successful application. Street can provide a computer analysis of magnet capacity requirements, the required crane speeds which in the foundry business will be dictated by optimum melt rates and the duty classifications necessary for each motion of the crane. Heavy duty open winch hoists such as the Street VX hoist are essential when scrap handling using magnets as the rope deviation destroys standard hoists.

Latest developments include programmable flux vector drives, anti-swing control and ‘auto homing’ which allows the operator to send the crane automatically to one or more co-ordinates.
