overhead crane using vfd

None of the overhead hoist and crane manufacturers, service and sales companies, out of the more than 1,500 we deal with directly, are using other than asynchronous motors. When we discuss the 90% efficiency achievable via the use of variable frequency drives (VFD), it's not optimistic, it's factual.

VFD for overhead crane | ATO.com

VFD speed regulating: Low consumption and high efficiency. At present, the new overhead crane regulating usually adopts the frequency conversion speed regulating mean. Some old overhead cranes are gradually transformed with the VFD. The characteristics of applying the VFD on the overhead crane: High positioning precision; Good vibration-proof

Today’s Variable Frequency Controls and Flux Vector Motor Controls have become the industry standard for crane and hoist control. VFD’s have replaced the older technologies of wound rotor motor control, static step-less and eddy- current. VFD’s are also making the use of two -speed control using contactors and two speed motors less practical.

Compensatory externals to aid in starting torque generation for synchronous motors are also basically expense burdens that need not be borne. The cost of the synchronous motor itself over the asynchronous motor, with increased in frame size, added copper and other materials, is another base reason synch motors are seldom, if ever used in the overhead hoist and crane industry. As far as pr

IMPULSE•G+ and VG+ Series 4. For Class C, D, E and F cranes the G+ and VG+ Series 4 adjustable frequency crane controls are the ideal choice. These variable speed drives have power modules which can withstand four times more thermal cycles than any other overhead material handling VFD's.

(Harbour cranes operate precisely and reliably even in high winds and poor weather with variable frequency drive. Ready to be connected Extended to form complete pre-assembled application modules, variable frequency drives offer you further benefits for a wide variety of travel and lifting requirements.

Drives and PLCs for cranes and hoists | ABB

Our variable frequency drives (VFD) and PLCs provide the intelligence, performance, flexibility and safety for your crane applications. Wherever the cranes are installed, our global service and support is always near. ACS880 drives with built-in crane control software and range of safety functions help various types of cranes move efficiently.

Magnetek IMPULSE G+ and VG+ Series 4 VFD/Adjustable Frequency Crane Controls. Magnetek's IMPULSE G+ and VG+ Series 4 drives are designed "from square one" for material handling applications and provide the most crane-specific capabilities far beyond any other general purpose drive's functionality.

This 40 Tons overhead crane has a standard general purpose VFD with break chopper and also controls the mechanical break. The problem is it does not use DC breaking to hold the weight before applying or releasing the mechanical break. This results in very high wear of break leathers. A few times weight fell and drive or break could not hold.

Jan 01, 2019 · This 40 Tons overhead crane has a standard general purpose VFD with break chopper and also controls the mechanical break. The problem is it does not use DC breaking to hold the weight before applying or releasing the mechanical break. This results in very high wear of break leathers. A few times weight fell and drive or break could not hold.

One of such initiatives is the use of variable frequency drives that work by increasing the time a crane will take to assume its full speed limit and to come to a pause, which, in turn, will work to minimise the forces that may lead to sway. Notably, the efficacy of such measures often depends on hook and load heights.
