Vulcan Engineering offers mold rollovers, rollover draw, and rollover closers for flaskless and flask nobake molds.
Donovan™ mold handlers, a product of Vulcan Engineering Co., offer a more safe and efficient way to handle the nobake molds in your foundry. The use of slings, chains and some other manipulators on the market lack the control of the mold that is inherent to the Donovan™ design. Donovan™ mold handlers have a long-standing reputation in the foundry industry for dependability and low maintenance. They offer 
superior control of the molds and can provide these major benefits for your foundry:
- Enables fewer people to handle heavy molds with minimum effort.
- Controlled mold handling reduces the risk of damage to the molds.
- Reduces the chance of costly injuries to your valuable employees.
Overhead crane hung models are available for both flaskless and flask type molds in standard models with capacities to 18,000 lbs. Custom designed units have been built with capacities of over 50,000 lbs.
Donovan mold handlers are available to clamp the molds from the ends or with the “picture frame” type to clamp large molds from the side.
