Bauer BF Series Geared Motors for Lumber Tilt Hoists
A lumber-handling equipment manufacturer needed a robust electric geared motor
solution to replace hydraulic cylinders on its tilt hoists. During operation, full bundles
of stacked, rough-cut lumber are moved onto the hoist. The entire bundle is then lifted
and tilted. As the tilted hoist slowly raises the bundle, single layers/rows of boards are
released from the top of the bundle and slide onto a feeder conveyer that transports the
boards for further finishing.
Bauer supplied BF60 parallel shaft gear motors to meet the customer’s application
requirements. Each tilt hoist utilizes two 30 HP geared motors that drive long ball
screws. The electric gear motors combined with the ball screws provide a more precise,
controlled movement of the hoist compared to hydraulic cylinders. The possibility of
damaging fluid leaks and cylinder creep/drift are also eliminated.
BF Series gearboxes feature high-tensile, case-hardened steel gearing with strong,
non-flexible pinion design and oversized input bearings to ensure exact tooth meshing
and longevity of the gearbox. Gearing is enclosed within a thick, reinforced, high-tensile
cast housing. Units feature a 3-piece labyrinth input seal to protect against oil leakage
in any orientation. Aluminum die-cast motor housings, bearing covers and terminal
boxes provide maximum corrosion-resistance. An aluminium die-cast cage rotor
ensures high reliability at high starting torques and low starting currents. Bauer motors
are manufactured in-house allowing for customization to meet specific application
requirements. All Bauer motors are inverter duty and IP65 rated as standard.
