MAXbase: Finding Room in Tight Spaces

 As job sites get increasingly compact, users want a solution that offers more flexibility in how they configure their Grove mobile cranes. 

The MAXbase function on Grove all-terrain cranes and some rough-terrain cranes is a great example of how innovative Manitowoc technology can deliver better performance from the same crane. MAXbase works by allowing users to position the crane’s outriggers in a wide variety of configurations, including asymmetric layouts. This enables them to select the optimum setup for the job.

Without MAXbase, crane outriggers must extend to the same distance when setting up. The issue with this is that a particular job site might not have a uniform layout for crane positioning (for example, if less space is available on the right side or left side). 

Andreas Cremer, Grove’s vice president of product management for mobile cranes, explains how MAXbase offers a workaround to this problem.  

“MAXbase makes asymmetric outrigger positioning possible. This maximizes a crane’s potential on constricted job sites, where obstacles can prevent outriggers from being fully extended,” he says. “MAXbase enables a greater variety of options for positioning the outriggers and removes the need for symmetry. It also provides improved load charts, allowing the crane to make better use of its full capacity. Ultimately, this means better rental rates for owners.”  

The Roll-Out Continues

Currently, MAXbase is available on 15 Grove all-terrain cranes and one rough-terrain crane, each of which has Manitowoc’s Crane Control System (CCS). It works seamlessly with CCS on the Grove AT cranes, displaying the limit of MAXbase’s lifting capacity and providing load charts for each configuration. CCS also makes the setup straightforward and intuitive for the operator with its boom configurator integrated into the crane’s menu navigation. For the 15 AT models that feature MAXbase, it can be retrofitted at any time, so there’s no problem if a customer decides to add it to a crane already in the field.

Ahead of a project, users can also harness MAXbase in the outrigger pad load calculation tool on Manitowoc’s homepage or for more detailed planning using the CRANEbee lift planning tool to help with preparations. 

MAXbase is proving such a popular option on all-terrain cranes, Grove is extending the technology into its Grove rough-terrain cranes. It includes all the functionality that Grove all-terrain crane users experience, as John Bair, Grove’s product manager for rough-terrain cranes, explains:

“With a traditional outrigger set-up for RT cranes, limited space forces users to set up outriggers at a reduced span or send a higher capacity crane to the job site – even though they feature a compact design,” he says. “But with MAXbase, users know they are lifting to the maximum possible capability of the crane in that configuration. This allows them to increase utilization and lower overall project costs.” 

Users of the GRT8120 with MAXbase will not only benefit from greater flexibility but also from MAXbase’s advanced lift calculation program that improves capacities throughout the 360° chart. 

Customer focus

MAXbase is another great example of how customers are seeing tangible increases in the earning power of their Grove cranes. With this innovative feature set to appear on ever more Grove cranes in the future, users can look forward to even more flexibility from their Manitowoc fleets.

MAXbase advantages:

  • Allows users to position the crane as close as possible to the lift
  • Improves access to tight job sites
  • Increased lift capacities throughout the 360° load chart
  • Enlarges the work area thanks to sector-defined load curves
  • More precisely identifies the need for a counterweight or jib, optimizing transport expenses
  • Fully compatible with the CRANEbee lift planning tool by CRANIMAX
