• Low Cost
• Works at 480VAC, 600VAC or 690VAC
• One MCC bucket per gearbox motor

 Disadvantages
• Special high slip motor
• Re-torqueing system required
• Wear and tear on the system is high
• Higher wear on the brake system
• Overdesign of the gearbox/pinion due to high starting torque.
• Limited number of jacking speeds
• Extra electrical losses due to use of high slip electric motors
• If one braking resistor fails the lift boat may not be able to be lowered

Variable Frequency Drive – AFE one per leg
 Advantages
• Active Front End (AFE) Variable frequency drive (VFD) which limits
harmonics
• Works at 480VAC, 600 VAC or 690VAC
• Continuously variable frequency/speed control from 0 to 100%
• One MCC bucket per gearbox motor
• No need for Re-torqueing
• Simple design but slightly more complex than the basic DOL system
• Limits wear and tear on the system because of smooth acceleration and
deceleration

 Disadvantages
• System is slightly more complex with AFE VFD technology
• If one braking resistor fails the lift boat may not be able to be lowered
• If any component of the AFE VFD fails, the lift boat cannot be raised or
completely lowered

Features/Benefits of the Jacking System
• Starting of movement of all legs at same time
• Accurate speed and torque (pinion load) control even at almost zero speed
• Smooth start up (torque increases slowly with brake engaged)
• Different speed levels for operation modes
• Equal load distribution for each pinion during movement
• Failsafe system to protect personnel and equipment
• Rack Phase Difference monitoring and correction is standard
• Main components are designed to be integrated together
• Reliable and easily maintained system
• Jacking is possible even after component failures
• Accurate load sharing reduces wear
• Standard off the shelf components
