The GHA12, GHB11, GHD13 incorporate frequency inverters to its hoist and cross travel movement as a standard feature. This inclusion has improved the performance of aspects such as speed control, movement precision, acceleration and load braking. This feature also prevents hazardous swing, improves motor protection and extends the working life of the motors and other crane mechanisms resulting in decreased maintenance costs.
GH has also decided to include a frequency converter for lifting, with these clear advantages:
Better speed and precise movement control.
Smoother startup and stopping movements.
Reduced starting current and more durable electric and mechanical components, motors, brakes and gears.
No wear to the brake as it functions as a parking brake.
Less power consumption.
