Geared Motor Solution For Lumber Tilt Hoists

Geared Motor Solution For Lumber Tilt Hoists

A robust electric geared motor solution was needed by a lumber-handling equipment manufacturer to replace hydraulic cylinders on its tilt hoists. Full bundles of stacked, rough-cut lumber are moved onto the hoist during operations. Then the entire bundles are lifted and tilted. Slowly the tilted hoist raises the bundle, single layers/rows of boards are released from the top of the bundle and slide onto a feeder conveyor 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 aluminum 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.
