If you’re looking for a one size fits all solution for Mill Roll Handling, a motorized lifter may be the best option for you. While they are quite complex and expensive when compared to other lifter styles, a motorized unit allows for a wide variety of roll or roll and chock configurations to be handled by a single unit.
This means less downtime to switch lifting devices for each different configuration, reducing the overall time required for a maintenance shut down. Motorized units also allow for completely hands-free operation, which reduces the number of personnel required to perform the lifting operation.
A motorized lifter offers a great degree of adjustability, to suit a wide range of load sizes. Also, because they already require power to operate, a motorized unit is easily incorporated in an automated crane system, with the addition of automation sensors and controls.
Motorized lifters can be designed to handle many different configurations of rolls & chocks: bare rolls, rolls with chocks, tandem rolls, and more. In many cases, a single lifter can be designed to handle a significant number of configurations and roll sizes.
A motorized unit isn’t without drawbacks though. They require an external power source and controls that need to be integrated with the crane. They are highly complex, which means more maintenance is involved in keeping them in top condition. Finally, they are quite heavy when compared to other equipment options, which may limit the load configurations that can be lifted with an existing crane.
The above being said the complexity and weight of this unit style is greatly overshadowed by the increase in efficiency and safety they can provide in a roll lifting operation. The reduction in time and personnel required allows more time for higher-value work to be done.
