CSV Stepless Speed Control Electric Chain Hoist
Load capacity 500Kg~2 tons, 1Hp variable frequency (speed control) dual speed
The lifting mechanism adopts a variable frequency speed control design to meet the needs of fast handling and slow positioning.
Features
- The braking resistor is mounted on an aluminum alloy casing and equipped with a hollow metal protective cover, which takes into account both heat dissipation and safety.
- Traditional overhead cranes are mostly single-speed designs. The intense vibrations during hoisting and braking can cause the transported goods to sway or become unstable, leading to injuries to personnel and making the goods prone to damage when they reach the ground.
- The lifting mechanism is implemented using the variable frequency principle.Speed control design (optional)This eliminates the violent speed jumps that occur when switching between fast and slow speeds in polarity motors or dual-motor designs.
- Traditional cranes use full-pressure starting and brakes are activated while the motor is still at high speed, causing motor overheating and excessive brake wear.
- By controlling the brakes and motor through the principle of frequency conversion, when the stop command is issued, the controller generates a reverse braking torque to the motor. The brake is activated when the motor speed approaches zero, which can effectively extend the life of the brakes and motor.
Advantage
- Stepless speed control reduces the swaying and shaking of loads during handling.
- When raising/lowering or positioning loads, it can significantly reduce the impact and vibration on structures and equipment.
- It saves electricity and extends the lifespan of mechanical parts.
- Built-in multiple protection functions: voltage detection, current detection, phase loss detection, and temperature detection.
Standard Functions
- Motor protection functions: overvoltage, overcurrent, and motor overheat protection.。
- 鏈條與吊鉤之斷裂荷重 > 5 倍額定荷重機械式過負荷保護裝置。
