MAXbase™
Maximize your crane's potential
Working under tight conditions is common on jobsites, and the challenge is that not all of the mobile crane's outriggers can be fully extended. MAXbase™ offers more flexibility on the jobsite by allowing asymmetrical outrigger positions, making it much easier to work in these conditions. In addition, the use of MAXbase™ increases the possible lifting capacity.
MAXbase™ benefits
Use MAXbase™ to benefit from sector-defined load charts. With higher lifting capacities and greater reach, even with lower counterweight, transportation costs can be reduced by eliminating the need for additional counterweight. MAXbase™ can be retrofitted on certain GMK and GRT cranes with Manitowoc’s Crane Control System (CCS).
Get the most out of your crane in even the tightest job sites.
- Position closer to your lift to reduce radius and take advantage of better lifting capacities.
- Enlarge your working area with sector-defined load charts to complete jobs.
- MAXbase™ versatility allows you to bring fewer accessories to the jobsite lowering your transport expenses.
Fitting into tight and constricted job sites is easier with MAXbase™.
- Variable outrigger bases provide greater versatility.
- The Crane Control System (CCS) displays the lifting capacity gained from MAXbase™ and offers calculated load charts for each configuration. It also makes it easy to select the right configuration and offers intuitive menu navigation.
- Simple planning - no guessing: Your projects can be planned for cranes featuring MAXbase™ either with the CRANIMAX CRANEbee software, via Lift Planning Tools on the Manitowoc website or directly on the crane using the boom configurator.
MAXbase™ can be retrofitted on certain GMK and GRT cranes with Manitowoc’s Crane Control System (CCS).
