For many years, the drive controls on overhead cranes were commonly single-speed, two-speed, or fixed-speed designs. These types of drives can be pretty rough on the brakes, gearboxes, couplers, and girders on the crane because the starting and stopping of the crane can be fairly abrupt.
With the introduction of variable frequency drives, microprocessors now control all the components of the drive system, and provide smoother acceleration and deceleration curves. This allows for smooth starts, smooth transitions, and smooth stopping which greatly reduces the strain on the gear boxes, couplers, girders, and other crane components.
This also greatly prolongs the life of the brake system as the computer controls and slows down the motor, while the brakes mostly act as a control to keep the crane from moving. Also, by eliminating the abrupt starting and stopping of the crane, you get far less load swing because the crane moves in a controlled manner—making it safer for everyone on the floor.
Magnetek designs them with versatility, reliability and safety in mind. Models range from basic, compact, low-cost units to advanced units featuring their exclusive crane and hoist software. Magnetek drives meet the demands of material handling applications from 1/4 HP to 1500 HP.
Drivecon has the products, knowledge, experience and technology to design, fabricate and support all your controls and electrification needs. Drivecon’s products range from standard and custom Variable Frequency Drive (VFD) panels, motors, radio controls, pendant stations and quick festoon systems to complete turnkey modernization projects.Magnetek’s family of Adjustable Frequency Drives is the industry leader.
Power Electronics (PE) products are known to be the most reliable in the industry. PE drives have the best ratings in the industry. The temperature rating alone is 50% higher. PE products are specifically engineered for crane and hoist use. Hardware and software are designed as one product—you get the maximum reliability and usability. PE products are Made In America with high reliability circuitry—not requiring extra parts or cards to “make it work.”
