GZT-PC Hoist Intelligent Frequency Conversion Electric Control System

I. Product Introduction

This system is designed with scientific, advanced, and reliable principles, featuring low power consumption, a PLC intelligent control system, and dynamic display on a touch screen. Daily hoisting operations are performed via handle speed change and direction reversal, along with a brake handle device. Equipped with multiple intelligent protection functions, the system ensures that incorrect operations do not trigger erroneous actions, while correct operations proceed normally, maximizing the safety of the hoisting system.

II. Main Functions

This system can monitor various operating parameters of the hoist in real-time, providing real-time fault alarms and control. Operational status monitoring mainly includes:

1. Hoisting direction, hoisting height, hoisting speed, hoisting acceleration/deceleration speed, constant speed overspeed protection

2. Creep zone speed limit protection

3. Wellhead positioning

4. Wellhead overwind, frequency conversion fault

5. Emergency stop

6. Hoisting cycle count memory

7. Signal count memory

8. Monitoring of the hydraulic braking system: brake shoe clearance, primary braking oil pressure, secondary braking oil pressure, brake disc runout, idle time, residual pressure of the hydraulic station, etc.

9. Monitoring of the motor and transmission parts: motor operating voltage, current, temperature of various bearing bushes in the reducer, temperature of the main shaft bearing bush, motor load bush, reducer oil pressure, oil temperature, etc.
