UniMAX® Bucket Elevator / Grain Legs

The UniMAX® bucket elevator is a high capacity centrifugal discharge elevator engineered to meet the most strict industry standards. The elevator head, boot, and intermediate sections have been designed with adequate space for buckets and belt to travel un-impeded throughout the system. Bucket spacing and belt speeds follow recommendations and standards set forth by industry leaders. UniMAX® bucket elevators are designed with cleanliness in mind by eliminating shelves for material to build up in the head, inspection doors, vents, access and boot section. The casings were also designed for afterthought installation of hazardous monitoring equipment to eliminate cutting and grinding on newly purchased elevators.

Safety is priority – UniMAX® elevators are built with the provisions to install hazardous monitoring equipment. The boot and head casings have removable covers to install belt alignment sensors and boot shafts are drilled and tapped for speed sensors. The boot bearing guards offer a take up location indicator and knock outs to access grease zerks and installation of bearing temperature sensors.

BUCKET ELEVATOR HEAD

The UniMAX® head has been designed with a crowned drum pulley with slide lagging. Inspection doors are included for inspecting the buckets, belt, deflector pad, and discharge throat. Incorporated are jack bolts to assist with aligning the bearings. Lifting eyes are contained in the lower head, up-leg and down-leg casings for rigging and maintenance. Removable covers for installation of belt alignment sensors are standard.

INTERMEDIATE SECTIONS AND LEGS

The intermediate section is constructed with seam welded 12-gauge trunking built in a jig. An optional 10-gauge upgrade for heavier construction is also offered. Included is an access section for easy maintenance of buckets and belts.

BELTING AND BUCKETS

We offer standard rubber belting with PVC, high temp, and food grade options are available upon request. HDPE Buckets come standard with all units but optional carbon steel, stainless steel, nylon, and urethane buckets are available as well. Buckets may be vented when the application requires it.

DRIVE OPTIONS

UniMAX® elevators offer two different drive packages all rated for Class II Service and are mounted on the right hand side when looking into the hopper. When purchased with a new elevator, the #2 drive package includes a shaft mounted reducer, v-belts, sheaves, v-belt guards and optional internal backstop. The #5 drive package includes a right hand mounted helical bevel gearbox with internal backstop and guards. Additional options for drive packages include motors, creep drives and dual drives.

BUCKET ELEVATOR BOOT

The UniMAX® Boot has a solid welded design for durability. Included are removable covers for installation of belt alignment sensors and for the installation of a shovel pocket. The boot shaft is drilled and tapped on both sides for installation of speed sensors.
