We have Spare Parts Bulletins and reference sheets, often more complete than the manufacturer and we know how to use them.

The Dependable DC Crane Controls that Gang Up On Downtime

Square D DC crane controls can make the difference between cranes that stay on the job - and cranes that don't, with costly downtime and lost productivity. Let us help you update your crane with our complete line of DC crane controls.

For example, we offer Front-Line® motor controllers in NEMA Sizes 1 through 8 for single motor and multimotor drives. TabWeld® power resistors rated from 13 to 500A. Youngstown® hoist power limit switches from 25 to 600 HP. Manual magnetic disconnect switches from 150 to 2700A. Master switches in three different types. And 8" through 30" brakes with torque ratings from 100 to 9000 ft./lbs.

We've made our experience pay off for you with proven product innovations. For instance, our Type M mill type contactor incorporates the Line-Arc® interrupting principle for longer life. And our rugged WB brake is easier to install, adjust and maintain. Plus it's available with an optional self-adjuster that automatically compensates for lining wear.
