Powermatic Universal Mobile Base JMB-UMB is a mobile machinery base designed to add flexibility to JET machines by putting heavy tools on wheels so they can be repositioned around the shop as needs change. The base expands from 18 in. wide by 18 in. long to 28 in. wide by 28 in. long, which lets you size the frame around different machines so the weight rests over the steel structure instead of hanging off edges. This adjustable width and length configuration supports the tool footprint, so sheet-metal cabinets and stands carry load more evenly during movement. The strong yet lightweight construction is rated to hold tools up to 600 lbs, so typical stationary machines in that range can be rolled instead of dragged. Two fixed and two swivel casters provide steering control at one end and pivoting at the other, allowing a single person to shift equipment through normal shop pathways.
The base expands from 18 in. wide by 18 in. long to 28 in. wide by 28 in. long, so the inner frame can be brought tight to compact stands or spread out for larger cabinets, supporting the machine footprint during rolling and parking. Adjustable width and length let you configure the base to the tool, which helps align machine feet over the frame corners and crossbars instead of unsupported sheet metal. This adjustable geometry aids fit-up when machines share similar but not identical base sizes, letting the same mobile base serve multiple tools at different times. The strong yet lightweight construction paired with this adjustment range helps maintain maneuverability even when the frame is expanded close to its maximum size.
The mobile base adds a new dimension of flexibility to JET machines because equipment that was previously considered immovable can be repositioned by only one person, allowing the shop layout to shift between ripping, assembly, or sanding setups as jobs change. With adjustable width and length, the frame can be configured to match the tool footprint, so cabinet bases and stands rest securely over the support points while moving across typical concrete or smooth shop floors. The expansion range from 18 in. x 18 in. to 28 in. x 28 in. lets a single mobile base serve different JET machines whose footprints fall within that envelope, which gives more options when rearranging workcells or clearing central space for large panels.
Two fixed and two swivel casters provide easy maneuverability by combining directional stability at one side with steering capability at the other, so one person can guide a 600 lb-class machine around obstacles without repeated lifting or shifting. The strong yet lightweight base supports tools up to 600 lbs, so the casters and frame carry that load while rolling instead of relying on dragging force across the floor, which helps keep machines aligned to their stands. Adjustable width and length let you configure the base to the tool for total support and portability, so when the machine is parked for use, its weight bears on a frame tailored to its footprint, helping it remain steady during normal operation. This configuration-focused design supports repeatable machine placement when rolling tools back to marked positions for ongoing workflows.
The Powermatic Universal Mobile Base JMB-UMB is described as adding flexibility to JET machines, so it is intended to carry JET equipment whose footprints and weights fall within the stated adjustment range and 600 lb capacity.
The adjustable width and length let you expand the base from 18 in. x 18 in. to 28 in. x 28 in., so you can size the frame around different tool footprints and keep the feet supported over the structure.
The mobile base is rated to hold tools up to 600 lbs, so machines within that range can be moved on casters rather than dragged, aiding layout changes while staying within the designed load limit.
The two fixed and two swivel casters provide easy maneuverability by letting one side track straight while the other steers, which helps guide machines through typical shop aisles and turns.
The strong yet lightweight base holds tools up to 600 lbs while remaining easier to position under machines, aiding handling when assembling the base and when rolling equipment around the shop.
The mobile base adds a new dimension of flexibility by allowing equipment previously considered immovable to be moved by only one person, so shop layouts can be rearranged for special projects within minutes.
The Powermatic Universal Mobile Base JMB-UMB pairs an 18 in. x 18 in. to 28 in. x 28 in. adjustment range with a 600 lb load rating, so JET machines within that envelope can be rolled between work zones instead of staying fixed. Two fixed and two swivel casters provide controlled maneuvering, giving one person the ability to angle heavy tools into position and return them to known spots when work is finished. For shops that need to rearrange machines quickly for special projects, this adjustable mobile machinery base offers a straightforward way to keep equipment mobile while still supporting the tool footprint during use.
