Drum Clamps are suitable for some designs of drums and may cause damage to others. The drums are carefully rolled down an inclined plane. During unloading, drums are inspected for damage and to ensure that they are properly labeled. A lift truck equipped with drum clamps picks up four drums of scrap metal from within an arrived truck trailer.
Drum Controllers are intended for starting and speed control of A.C. slip ring induction motors , which drives various motions of cranes of all types and other machinery. The controllers are provided with direct stator reversing contacts as well as rotor resistance control. Contacts are standard, with current ratings upto 250 amps., for higher current ratings stator reversing is performed through contractors. Reversing contractors are controlled through auxiliary contacts provided in the enclosure.
Drum drainers consist of a high volume draining screen and draining belt for final draining and the application of gentle pressure to present dry curt to the creamers. Curd and water is pumped into the drum drainer and runs across the high volume screen. The effectiveness of the drainer is controlled by the speed of the curd pump. Then the curd is gently squeezed as the draining belt runs the curd over a drum. The dry curd exits the drum drainer and drops into the creamer.
