Solution for C900 in electrical chain hoist

Electrical chain hoist with the inverter used in it is known as Frequency changed electrical cable hoist , the performance of the whole machine has improved a lot after it uses the inverter as its drive and it has the characteristics of smoothly and stably going up and down as well as achieving an accurate positioning to the hanging objects.

And take the complete self-protecting function of inverter, like it can alarm in time and stop when over current, overloading,over voltage etc... occurs into consideration, it decrease the rising in temperature of the motor, decrease the breakdown of the Electric hoist and improve its safety.

Features and advantage of C900

- Characteristics of Inverter special for Electrical chain hoist

- It has a compact structure;
- It has a special design for heat radiation;
- It has a function of operating stop;
- It can be used with all types of Electrical chain hoist.

Solution for C900 in electrical cable hoist

Electrical cable hoist is a common, light and small lifting equipment, it can be fixed on the mono spar, move horizontally, directly lift the goods vertically and do the loading and unloading operation to the goods on the given place. The motor of Electrical cable hoist uses the motor control mode of cone.

While the past Electrical hoist doesn’t use the control of inverter, the current and mechanical shock would be very big during the starting-up, the lifting hook would even slide when the coordination of time or order failed and the speed of going up and down also can’t be controlled. After that, the operating performance has been improved a lot when the inverter was adopted in the Electric hoist to change the frequency change of the power suppliers and control the rotary speed of motor.

Features and advatages of C900

- This is for the Electrical cable and chain hoist which have the cone rotor motor special use
- The control on current vectors is of high efficiency;
- The high resolution ratio and stable inspection on the position of magnetic pole can both help to achieve a stable start-up
- The S curve acceleration, thus making the acceleration and deceleration very stable;
- The speed accuracy is +-0.2%, the torque precision is +-5%.
