Why does an electric arm truck perform differently than a hydraulically powered diesel arm truck?? The simplest answer is because of the limitations of DC drive systems.。Conventional DC motors with brushes are limited in speed，Low transmission ratio、High motor torque。Due to the change in the polarity of the magnetic field，The speed of the twisting torque of the device becomes very slow，This results in the machine accelerating and decelerating significantly before，There is a long lag time.。

Gini pioneered new AC drive technology，For electric and fuel electric arm vehicles。Our direct drive design is suitable for indoor use、Outdoor work at height，The working efficiency of the high-altitude vehicle is improved without sacrificing the driving performance.。The performance of these devices is no less than that of hydraulically driven diesel machines.，But also can save the cost and the fuel consumption of the engine.。

Three Performance Advantages of AC Drive

Maintenance-free and more efficient

Four times more efficient than conventional hydraulic drives

For more than a decade.，Gini continues to improve the AC drive system，Improve the working efficiency of the equipment，Maximize battery life。The maintenance-free AC drive system designed by Gini will，The brake and the gearbox are integrated，No need to change brushes or commutator，Extend device life， Reduced maintenance cost。

The Gini AC drive system is 50% more efficient than the DC electro-hydraulic drive%。DC pump motor driven hydraulic pump，Provide power for lifting and driving function，Additional valves and hoses are required to control the speed，Resulting in power loss and heat generation。And the heat wastes battery capacity.，That's why 6,The 123 kg electro-hydraulic drive requires 300 amps of current，And 7,756 kilosZ-60/37DCAndFEThe arm truck is driven by AC flow，It only needs 125 amperes of current.，This greatly extends battery life.。

At the same time，AC drive simplifies mechanical braking system，Brake pads do not need to be worn or replaced，The service life of the arm vehicle is prolonged.。A speed sensor is used，Efficient regenerative braking helps the unit maintain consistent travel speed，And return some of that energy to the battery，Further extends the life of a single charge。

High waterproof grade

Reduced maintenance costs 35%

One of the main advantages of an AC drive system is that it provides more accurate low speed control than a DC drive，Easy positioning，Unlike liquid drives, which require calibrating the device back and forth to the operating point.。

Gini electric arm carZ-60 andFEThe traction of the hybrid equipment is actually better than most hydraulically driven diesel models.。Even when driving to the maximum steering angle，The AC drive system also balances the torque to each wheel，Hydraulic drive can't do that.。In addition，AC drive for full torque on all four wheels，Even if one wheel loses traction，The torque of the other three wheels is not affected.。

Many DC drive arm trucks have a protection level of onlyIP40, Dust and water can penetrate into the drive system，Suitable for outdoor dry floors only。Gini's sealed AC drive has a protection rating ofIP67，Waterproof and dustproof，It can work safely even in 1 meter deep water.。

Reduce total cost of ownership of equipment

Enhance Return on investment

Customers are most concerned about the efficiency of equipment use and cost control.。The Gini AC drive system combines these two aspects well.，Suitable for indoor and outdoor site applications。Hybrid models only need 18kWA small engine，Rental customers can save on fuel costs，But also does not need to carry out complicated maintenance on the tail gas treatment system.。
