Application of INVT GD300-39 all-in-one machine in construction elevator

Elevator adopts variable frequency speed to solve the above problems, which has greatly improved the performance and safety of construction elevator.

With the continuous development of China's construction industry and the improvement of construction mechanization level, the requirements of construction elevator’s manufacture and technical level of all-in-one machine are getting higher and higher; its operating conditions directly affect the construction progress. The traditional construction elevator generally uses the contactor - relay control, direct start and mechanical brake forced braking, and the large brake impact has greatly affected the service life of mechanical structure.

The main components of construction elevator are as follows: rail frame, cage, transmission system, wall-attached frame, chassis fence, electrical systems, safety protection devices, cable power supply devices.

Ordinary construction elevator has a poor comfort due to adopting the direct start and stop of industrial frequency. In order to upgrade the start and stop comfort, some manufacturers install the inverter to the construction ladder, and the system adopts a contactor - relay + inverter control mode, but the inverter is basically only used for speed control. And the device can be equipped with PLC control module and floor calling and leveling device. The construction elevator installed with leveling device can be better controlled and more accurately stops in the required floor; the calling device of installing floor is convenient for information circulation and management.

The electrical system introduced in this paper is the frequency conversion and adjusting speed of construction lifting all-in-one machine, The internal integrated signal logic processing of inverter has a rich expansion capability while replacing the PLC, which has tightly combined the variable frequency, speed regulation and contactor control system.
