P4 UniMiner

Heavy Duty Conveyor Drives - Heavy Duty Design; Proven in the Field
The Hansen P4 UniMiner features a robust design that offers versatility for
different mounting positions. With a ‘flippable’ housing and horizontal
split line, it’s the ideal alignment-free drive package.
Hansen Industrial Gearboxes’ P4 UniMiner gear units are compact
and optimized for mining and other applications involving
bulk material handling.
Drop-In replacement for most other alignment-
free drives.
The Paramax® UniMiner is built on the reliable existing product platform and incorporates
a new housing design that can reduce product inventories when both left and
right handed assemblies are required.
Paramax® gearboxes are compact and proven in mining and other
heavy-duty applications. They excel in all types of bulk material handling
applications and provide long and trouble-free operation.
Paramax® UniMiner can be a direct drop-in to most other alignment-
free, shaft mounted drive packages.

Retro-Fits

Match Existing Footprint
A custom transition base will position the new low-speed shaft to be in the EXACT same position as the original low-speed shaft. Our retrofits provide an excellent balance between the cost savings of a standard gearbox and the benefits of minimal on-site modifications.
Typically, only relocating the motor mount is required for this option. We offer motor mounting options to help minimize the impact of relocating the motor mount, such as flanged motor adapter for c-face or d-flange motors.
Options might include a special low-speed shaft diameter or length and motor lantern.
The red circles in the diagram represent the existing bolt pattern of a customer’s unit. The transition base is fabricated to match the height, ensuring alignment of the low-speed shaft to the machine shaft.
Retro-Fit units with transition bases allow us to match your
existing footprint for an easier upgraded installation.
